DC GENERATION SYSTEM-INTRODUCTIONPurposeThe DC generation system makes a nominal 28v dc for airplane systems.GeneralThe DC generation system has these components:- Battery- Battery charger- Transformer rectifier units (3).DC GENERATION SYSTEM - GENERAL DESCRIPTIONGeneral DescriptionThe DC generation system supplies a nominal 28v dc to different loads. The power source for the DC system is usually the AC system. The battery supplies power if the AC system is not available.Transformer Rectifier UnitsTo create DC power from the normal AC source, the DC system uses transformer-rectifier units (TRUs). The three TRUs take 115v ac, decrease the voltage (transforms), and rectify it to a nominal 28v dc.Battery ChargersThe main battery charger and auxiliary battery charger give a DC voltage output to charge their respective battery. Each charger operates like a TRU after the battery gets to full charge. The main battery charger sends a constant DC voltage to the battery and the hot and switched hot battery buses. The auxiliary battery and auxiliary battery charger power DC buses only during non-normal conditions. See the standby power system section for more information. (AMM PART I 24-34)BatteriesEach battery is a 48 ampere-hour, nominal 24v dc power source. The main battery supplies power for APU starting and is a standby power source if all other power supplies do not operate. The auxiliary battery helps the main battery supply standby power only.Control and ProtectionThe standby power control unit (SPCU), the battery switch, and the standby power switch give primary control of the DC system.The battery switch and the standby power switch give manual control of power to some DC buses. The SPCU gives automatic control and protection of DC buses. It uses inputs from the flight compartment and system monitoring to control DC power sources and distribution.Power DistributionThe DC power distribution system is in the powerdistribution panels (PDPs) and in the SPCU.DC GENERATION SYSTEM - MAIN BATTERY CHARGERAND AUXILIARY BATTERY CHARGERPurposeThe main battery charger has these two functions:- Keeps main battery at maximum charge- Supplies DC power to the battery buses.The auxiliary battery charger keeps the auxiliary battery at maximum charge.General DescriptionBoth battery chargers have the same part number. Each battery charger has these two basic modes of operation:- Battery charge mode (constant current)- Transformer rectifier mode (constant voltage).Each battery charger supplies constant current, variable voltage power in the battery charge mode. The battery charger overcharges the battery. The battery charger logic calculates the amount of overcharge. The total charge time is less than 75 minutes.In the transformer rectifier (TR) mode, the main battery charger supplies constant voltage DC power to the hot battery bus and the switched hot battery bus.The main battery also receives a small trickle charge to help keep it at maximum charge. The auxiliary battery charger does not supply power to the DC buses in either mode. However, the auxiliary battery receives a small trickle charge when the auxiliary battery charger is in the TR mode.The front face of each battery charger has two green status lights (LED). One light is for the battery charger and the other is for the battery. These lights are on when the battery and battery charger are in operation.LocationThe main battery charger is on the E2 rack. The auxiliary battery charger is on the E3 rack.Functional DescriptionEach battery charger takes three-phase, 115v ac power and changes it to DC power. Usually, each battery charger is in the transformer rectifier mode. The battery chargers supply a constant voltage output in this mode. Each charger can supply up to 65 amps in this mode.A battery charger goes to the charge mode when its battery voltage is less than 23v dc. In this mode, the charger supplies constant current power. The output voltage is variable. During the charge, the battery voltage rises until the voltage gets to the inflection point. The charger logic uses the battery temperature at the start of charging to calculate the inflection point. The charger logic then calculates the length of the overcharge period.After the overcharge period, the charger goes into a transformer rectifier mode with a constant 27.5v dc output. The battery gets a trickle charge in this mode.The battery charger goes into the charge mode again if any of these occur:- Battery charger input power is off for more than 1 second.- Battery voltage is less than 23 volts.You use the electrical meters, battery, and galley power module to monitor the operation of eachbattery charger. The main battery charger is in the charge mode when you see a positive DC AMPS indication while the DC meter selector in the BA T position. Use the AUX BAT position to monitor the auxiliary battery charger.The main battery charger cannot go into the charge mode during any of these conditions:- Fueling station door open- APU start- Standby power switch (P5-5) in the BAT position- Standby power switch (P5-5) in the AUTO position, battery switch ON, and DC BUS 1 and AC TRANSFER BUS1 do not have power- Main battery overheat.The auxiliary battery charger cannot go into the charge mode during any of these conditions:- Standby power switch (P5-5) in the BAT position- Standby power switch (P5-5) in the AUTO position, battery switch ON and DC BUS 1 and AC TRANSFER BUS 1 do not have power.- Auxiliary battery overheat.Status LightsBoth status lights are usually on when the battery charger has input power. A malfunction with any of these components makes one or both status lights go off:- Battery charger- Battery- Connection wiring.Both status lights are off if any of these conditions are true:- Input power to the battery charger goes away- Input voltage to the battery charger is less than 94v ac for more than 0.5 seconds.The battery charger status light is on and the battery status light is off if any of these conditions are true:- Battery charger senses a loss of connection to the battery- Battery overheat- Battery temperature sensor open or shorted- Battery not charged in time limits- Battery voltage less than lower limits.The battery charger status light is off and the battery status light is on when there is an internal battery charger failure. The battery charger fail maintenance message also shows on P5-13 BITE.DC GENERATION SYSTEM-BATTERY CHARGER-FUNCTIONALDESCRIPTIONFunctional DescriptionThe battery charger takes 3-phase, 115v ac power and changes it to dc power. Usually, the battery charger is in the transformer rectifier mode. The battery charger supplies a constant voltage output in this mode. The charger can supply up to 65 amps in this mode.The battery charger goes to the charge mode when the battery voltage goes below 23v dc. In this mode, the charger supplies constant current power. The output voltage is variable, the currentoutput is 50 amps. During the charge, the battery voltage increases until the voltage gets to the inflection point. The charger logic uses the battery temperature at the start of charge to calculate the inflection point. The charger logic then calculates the length of the overcharge period.After the overcharge period, the charger goes into a transformer rectifier mode with a constant 27.5v dc output. The battery gets a trickle charge in this mode.The battery charger goes into the charge mode again if any of these occur:- Battery charger input power is off for more than 1 second- Battery voltage goes below 23 volts.You use the electrical meters, battery and galley power module to monitor the operation of the battery charger.The battery charger is in the charge mode when you see a positive DC AMPS indication when the DC meter selector in the BAT position.The battery charger cannot go into the charge mode during any of these conditions:- Fueling station door open- APU start- Standby power switch (P5-5) to the BAT position- Standby power switch (P5-5) to the AUTO position, battery switch ON, and DC BUS 1 and AC TRANSFER BUS 1 do not have power- Battery overheat.DC GENERATION SYSTEM - MAIN BATTERY AND AUXILIARY BATTERY PurposeThe main battery has these functions:- Supply power to critical airplane systems (AC and DC standby buses) if the normal power sources are not available- Backup power supply for the AC system control and protection- Power supply for APU start.The auxiliary battery helps the main battery supply power to the critical airplane systems (AC and DC standby buses).LocationThe batteries are in the EE compartment, under the E3 rack. The auxiliary battery is forward of the main battery. You remove an access panel in the forward cargo compartment to get access to the batteries. You must remove the main battery before you can remove the auxiliary battery.General DescriptionEach battery is a 20 cell nickel-cadmium battery with a 48 amp-hour capacity. With full charge, the batteries supply a minimum of 60 minutes of standby AC and DC power.Each battery has an internal thermal sensor. The battery's charger uses this sensor to measure internal battery temperature. See the MAIN BA TTERY CHARGER AND AUXILIARY BA TTERY CHARGER page in this section for more information.You can see the output of each battery on the electrical meters, battery and galley power module on the P5 forward overhead panel. You see the voltage and current output of a battery with the DC meter selector in the BAT position or AUX BAT position. If the battery's charger has power, you see the output voltage of the battery or its battery charger, whichever is more.The amber BAT DISCHARGElight comes on when any one of these output conditions are true for either battery:- Current draw is more than 5 amps for 95 seconds- Current draw is more than 15 amps for 25 seconds- Current draw is more than 100 amps for 1.2 seconds.Master caution and the ELEC annunciator usually come on with the BA T DISCHARGE light. The light goes out when the output current goes below the limit for more than 1 second. Master caution and the ELEC annunciator do not come on during a DC power APU start.Training Information PointYou remove a battery from the airplane before you do a battery inspection or servicing.DC GENERATION SYSTEM - DUAL BATTERY REMOTECONTROL CIRCUIT BREAKERPurposeThe dual battery remote control circuit breaker (RCCB) puts the output of these in parallel:- Auxiliary battery- Auxiliary battery charger- Main battery- Main battery charger.LocationThe RCCB is inside the J9 junction box. J9 is in the EE compartment, in front of the E2 rack.General DescriptionThe RCCB is normally open and closes when the SPCU signals it to close. This lets the 28v dc battery bus bar receive power from the main and auxiliary batteries at the same time.DC GENERATION SYSTEM - TRANSFORMER RECTIFIER UNIT (TRU) PurposeThe transformer rectifier units (TRU) change three-phase nominal 115v ac, 400 hz input power into 28v dc to supply the main DC system loads.General DescriptionThe DC generation system has three TRUs. Each TRU can supply a continuous output load of 75 amps, with forced air cooling. The TRUs can supply 50 amps, with convection cooling.There are no external controls to the TRUs. The TRUs are the same part number.The TRUs are in the EE compartment. TRU 1 is on the E2 rack. TRU 2 and TRU 3 are on the E4 rack.IndicationYou may monitor output power for each TRU from the P5-13. You can use the DC meter selector to select the TRU. TRU output voltage and amperes show in the alphanumeric display.The amber TR UNIT light comes to show a TRU failure.The light comes on for any of these conditions:- Any TRU fails on the ground- TRU 1 fails in flight- TRU 2 and TRU 3 fail in flight.DC GENERATION SYSTEM-BATTERY BUSES-FUNCTIONALDESCRIPTIONHot Battery Bus PowerThe hot battery bus receives DC power from the battery through a 28VDC bat bus bar in the J9 battery shield.There is a circuit breaker on the SPCU that permits power to the bus.The 28v dc battery bus bar receives DC power from the main battery or the main battery charger under normal power conditions. On standby power the 28v dc battery bus bar receives power from the main battery and the auxiliary battery.Switched Hot Battery Bus PowerThe switched hot battery bus receives DC power from the 28v dc battery bus bar through a circuit breaker on the SPCU and relay K8 in the SPCU.To get power to the switched hot battery bus, the battery switch must be ON. When the battery switch is ON, K8 SW HOT BAT BUS RL Y closes and gives dc power to the bus.With the forward airstair option, the K8 relay closes when the airstair handle is put in the standby position.The K8 relay gives DC power from the 28v dc battery bus bar to the SPCU power supply.Battery Bus PowerThe battery bus receives power from the 28v dc battery bus bar or TRU 3.The BA T BUS NORM RL Y (K2) is closed and gives DC power from TRU3 to the battery bus when all of these conditions are true:- BATTERY SW ON- STANDBY POWER SW not in BAT position- TRU 3 gets more than 18v dc for more than 0.15 seconds.- When the K2 relay is closed, the BAT BUS ALT RL Y(K1) must be opened.The K1 BAT BUS ALT RL Y is closed and gives power to the BATTERY BUS during these conditions:- Battery switch is ON and TRU 3 does not have power (less than 18v dc) for more than 0.1 seconds or- STANDBY POWER SWITCH is in the BAT position.直流电系统－介绍目的直流电系统产生28 伏直流供飞机系统。

DC GENERATION SYSTEM-INTRODUCTIONPurposeThe DC generation system makes a nominal 28v dc for airplane systems.GeneralThe DC generation system has these components:- Battery- Battery charger- Transformer rectifier units (3).DC GENERATION SYSTEM - GENERAL DESCRIPTIONGeneral DescriptionThe DC generation system supplies a nominal 28v dc to different loads. The power source for the DC system is usually the AC system. The battery supplies power if the AC system is not available.Transformer Rectifier UnitsTo create DC power from the normal AC source, the DC system uses transformer-rectifier units (TRUs). The three TRUs take 115v ac, decrease the voltage (transforms), and rectify it to a nominal 28v dc.Battery ChargersThe main battery charger and auxiliary battery charger give a DC voltage output to charge their respective battery. Each charger operates like a TRU after the battery gets to full charge. The main battery charger sends a constant DC voltage to the battery and the hot and switched hot battery buses. The auxiliary battery and auxiliary battery charger power DC buses only during non-normal conditions. See the standby power system section for more information. (AMM PART I 24-34)BatteriesEach battery is a 48 ampere-hour, nominal 24v dc power source. The main battery supplies power for APU starting and is a standby power source if all other power supplies do not operate. The auxiliary battery helps the main battery supply standby power only.Control and ProtectionThe standby power control unit (SPCU), the battery switch, and the standby power switch give primary control of the DC system.The battery switch and the standby power switch give manual control of power to some DC buses. The SPCU gives automatic control and protection of DC buses. It uses inputs from the flight compartment and system monitoring to control DC power sources and distribution.Power DistributionThe DC power distribution system is in the powerdistribution panels (PDPs) and in the SPCU.DC GENERATION SYSTEM - MAIN BATTERY CHARGERAND AUXILIARY BATTERY CHARGERPurposeThe main battery charger has these two functions:- Keeps main battery at maximum charge- Supplies DC power to the battery buses.The auxiliary battery charger keeps the auxiliary battery at maximum charge.General DescriptionBoth battery chargers have the same part number. Each battery charger has these two basic modes of operation:- Battery charge mode (constant current)- Transformer rectifier mode (constant voltage).Each battery charger supplies constant current, variable voltage power in the battery charge mode. The battery charger overcharges the battery. The battery charger logic calculates the amount of overcharge. The total charge time is less than 75 minutes.In the transformer rectifier (TR) mode, the main battery charger supplies constant voltage DC power to the hot battery bus and the switched hot battery bus.The main battery also receives a small trickle charge to help keep it at maximum charge. The auxiliary battery charger does not supply power to the DC buses in either mode. However, the auxiliary battery receives a small trickle charge when the auxiliary battery charger is in the TR mode.The front face of each battery charger has two green status lights (LED). One light is for the battery charger and the other is for the battery. These lights are on when the battery and battery charger are in operation.LocationThe main battery charger is on the E2 rack. The auxiliary battery charger is on the E3 rack.Functional DescriptionEach battery charger takes three-phase, 115v ac power and changes it to DC power. Usually, each battery charger is in the transformer rectifier mode. The battery chargers supply a constant voltage output in this mode. Each charger can supply up to 65 amps in this mode.A battery charger goes to the charge mode when its battery voltage is less than 23v dc. In this mode, the charger supplies constant current power. The output voltage is variable. During the charge, the battery voltage rises until the voltage gets to the inflection point. The charger logic uses the battery temperature at the start of charging to calculate the inflection point. The charger logic then calculates the length of the overcharge period.After the overcharge period, the charger goes into a transformer rectifier mode with a constant 27.5v dc output. The battery gets a trickle charge in this mode.The battery charger goes into the charge mode again if any of these occur:- Battery charger input power is off for more than 1 second.- Battery voltage is less than 23 volts.You use the electrical meters, battery, and galley power module to monitor the operation of eachbattery charger. The main battery charger is in the charge mode when you see a positive DC AMPS indication while the DC meter selector in the BA T position. Use the AUX BAT position to monitor the auxiliary battery charger.The main battery charger cannot go into the charge mode during any of these conditions:- Fueling station door open- APU start- Standby power switch (P5-5) in the BAT position- Standby power switch (P5-5) in the AUTO position, battery switch ON, and DC BUS 1 and AC TRANSFER BUS1 do not have power- Main battery overheat.The auxiliary battery charger cannot go into the charge mode during any of these conditions:- Standby power switch (P5-5) in the BAT position- Standby power switch (P5-5) in the AUTO position, battery switch ON and DC BUS 1 and AC TRANSFER BUS 1 do not have power.- Auxiliary battery overheat.Status LightsBoth status lights are usually on when the battery charger has input power. A malfunction with any of these components makes one or both status lights go off:- Battery charger- Battery- Connection wiring.Both status lights are off if any of these conditions are true:- Input power to the battery charger goes away- Input voltage to the battery charger is less than 94v ac for more than 0.5 seconds.The battery charger status light is on and the battery status light is off if any of these conditions are true:- Battery charger senses a loss of connection to the battery- Battery overheat- Battery temperature sensor open or shorted- Battery not charged in time limits- Battery voltage less than lower limits.The battery charger status light is off and the battery status light is on when there is an internal battery charger failure. The battery charger fail maintenance message also shows on P5-13 BITE.DC GENERATION SYSTEM-BATTERY CHARGER-FUNCTIONALDESCRIPTIONFunctional DescriptionThe battery charger takes 3-phase, 115v ac power and changes it to dc power. Usually, the battery charger is in the transformer rectifier mode. The battery charger supplies a constant voltage output in this mode. The charger can supply up to 65 amps in this mode.The battery charger goes to the charge mode when the battery voltage goes below 23v dc. In this mode, the charger supplies constant current power. The output voltage is variable, the currentoutput is 50 amps. During the charge, the battery voltage increases until the voltage gets to the inflection point. The charger logic uses the battery temperature at the start of charge to calculate the inflection point. The charger logic then calculates the length of the overcharge period.After the overcharge period, the charger goes into a transformer rectifier mode with a constant 27.5v dc output. The battery gets a trickle charge in this mode.The battery charger goes into the charge mode again if any of these occur:- Battery charger input power is off for more than 1 second- Battery voltage goes below 23 volts.You use the electrical meters, battery and galley power module to monitor the operation of the battery charger.The battery charger is in the charge mode when you see a positive DC AMPS indication when the DC meter selector in the BAT position.The battery charger cannot go into the charge mode during any of these conditions:- Fueling station door open- APU start- Standby power switch (P5-5) to the BAT position- Standby power switch (P5-5) to the AUTO position, battery switch ON, and DC BUS 1 and AC TRANSFER BUS 1 do not have power- Battery overheat.DC GENERATION SYSTEM - MAIN BATTERY AND AUXILIARY BATTERY PurposeThe main battery has these functions:- Supply power to critical airplane systems (AC and DC standby buses) if the normal power sources are not available- Backup power supply for the AC system control and protection- Power supply for APU start.The auxiliary battery helps the main battery supply power to the critical airplane systems (AC and DC standby buses).LocationThe batteries are in the EE compartment, under the E3 rack. The auxiliary battery is forward of the main battery. You remove an access panel in the forward cargo compartment to get access to the batteries. You must remove the main battery before you can remove the auxiliary battery.General DescriptionEach battery is a 20 cell nickel-cadmium battery with a 48 amp-hour capacity. With full charge, the batteries supply a minimum of 60 minutes of standby AC and DC power.Each battery has an internal thermal sensor. The battery's charger uses this sensor to measure internal battery temperature. See the MAIN BA TTERY CHARGER AND AUXILIARY BA TTERY CHARGER page in this section for more information.You can see the output of each battery on the electrical meters, battery and galley power module on the P5 forward overhead panel. You see the voltage and current output of a battery with the DC meter selector in the BAT position or AUX BAT position. If the battery's charger has power, you see the output voltage of the battery or its battery charger, whichever is more.The amber BAT DISCHARGElight comes on when any one of these output conditions are true for either battery:- Current draw is more than 5 amps for 95 seconds- Current draw is more than 15 amps for 25 seconds- Current draw is more than 100 amps for 1.2 seconds.Master caution and the ELEC annunciator usually come on with the BA T DISCHARGE light. The light goes out when the output current goes below the limit for more than 1 second. Master caution and the ELEC annunciator do not come on during a DC power APU start.Training Information PointYou remove a battery from the airplane before you do a battery inspection or servicing.DC GENERATION SYSTEM - DUAL BATTERY REMOTECONTROL CIRCUIT BREAKERPurposeThe dual battery remote control circuit breaker (RCCB) puts the output of these in parallel:- Auxiliary battery- Auxiliary battery charger- Main battery- Main battery charger.LocationThe RCCB is inside the J9 junction box. J9 is in the EE compartment, in front of the E2 rack.General DescriptionThe RCCB is normally open and closes when the SPCU signals it to close. This lets the 28v dc battery bus bar receive power from the main and auxiliary batteries at the same time.DC GENERATION SYSTEM - TRANSFORMER RECTIFIER UNIT (TRU) PurposeThe transformer rectifier units (TRU) change three-phase nominal 115v ac, 400 hz input power into 28v dc to supply the main DC system loads.General DescriptionThe DC generation system has three TRUs. Each TRU can supply a continuous output load of 75 amps, with forced air cooling. The TRUs can supply 50 amps, with convection cooling.There are no external controls to the TRUs. The TRUs are the same part number.The TRUs are in the EE compartment. TRU 1 is on the E2 rack. TRU 2 and TRU 3 are on the E4 rack.IndicationYou may monitor output power for each TRU from the P5-13. You can use the DC meter selector to select the TRU. TRU output voltage and amperes show in the alphanumeric display.The amber TR UNIT light comes to show a TRU failure.The light comes on for any of these conditions:- Any TRU fails on the ground- TRU 1 fails in flight- TRU 2 and TRU 3 fail in flight.DC GENERATION SYSTEM-BATTERY BUSES-FUNCTIONALDESCRIPTIONHot Battery Bus PowerThe hot battery bus receives DC power from the battery through a 28VDC bat bus bar in the J9 battery shield.There is a circuit breaker on the SPCU that permits power to the bus.The 28v dc battery bus bar receives DC power from the main battery or the main battery charger under normal power conditions. On standby power the 28v dc battery bus bar receives power from the main battery and the auxiliary battery.Switched Hot Battery Bus PowerThe switched hot battery bus receives DC power from the 28v dc battery bus bar through a circuit breaker on the SPCU and relay K8 in the SPCU.To get power to the switched hot battery bus, the battery switch must be ON. When the battery switch is ON, K8 SW HOT BAT BUS RL Y closes and gives dc power to the bus.With the forward airstair option, the K8 relay closes when the airstair handle is put in the standby position.The K8 relay gives DC power from the 28v dc battery bus bar to the SPCU power supply.Battery Bus PowerThe battery bus receives power from the 28v dc battery bus bar or TRU 3.The BA T BUS NORM RL Y (K2) is closed and gives DC power from TRU3 to the battery bus when all of these conditions are true:- BATTERY SW ON- STANDBY POWER SW not in BAT position- TRU 3 gets more than 18v dc for more than 0.15 seconds.- When the K2 relay is closed, the BAT BUS ALT RL Y(K1) must be opened.The K1 BAT BUS ALT RL Y is closed and gives power to the BATTERY BUS during these conditions:- Battery switch is ON and TRU 3 does not have power (less than 18v dc) for more than 0.1 seconds or- STANDBY POWER SWITCH is in the BAT position.直流电系统－介绍目的直流电系统产生28 伏直流供飞机系统。
