All major components are manufac t ured by Eaton, establishing one source of responsibility for the equipment’s performance and ensuring high standards in quality, coordination, reliability and service.A complete line of Eaton switches and fuses is available:■■38 kV voltage class■■600 A continuous loadinterrupting ratings■■Non-fused or fused with current limiting or boric acid-type fuses■■Manual or motor operated■■Indoor or outdoor non-walk-in enclosures■■Single switches and transformer primary switches■■Duplex loadbreak switch arrange m ents for selection of alternate feeds■■Lineups with main bus■■Standard arrangements with auto m atic transfer control systems (two sources feeding one bus or two sources feeding two buses on a split bus with tie switch) Standard design configurations for:■■NEMA T pads for cable lugs■■Surge arresters■■Instrument transformers■■Control power transformers■■Power Xpert T and IQelectronic metering■■Other auxiliary equipmentOutdoor Duplex with Customer MeteringApplication DescriptionEaton’s Load Interrupter T ype MVSmetal-enclosed switchgear provides safe,reliable switching and fault protectionfor medium-voltage circuits rated to38 kV. T he MVS switch is ideal forapplications where high duty cycleoperation is not required.MVS switchgear has the advantage oflow initial cost inherent in switch designswhile offering the characteristics mostvital to safety and coordination.The MVS switch’s quick-make, quick-break mechanism provides full-loadcurrent interrupting capability whilefuses provide accurate, permanentlycalibrated short circuit detecting andinterrupting capabilities. Visibility ofactual blade position improves safetyby giving positive assurance of circuitde-energization.Standards and CertificationsEaton’s MVS load interrupter switchgearmeets or exceeds the requirements ofthe following industry standards:■■IEEE T Standard C37.20.3■■ANSI C37.57■■NEMA SG5■■Canadian Standard CAN/CSA RC22.2 No. 31Type MVS switches meet or exceedthe requirements of the followingindustry standards:■■IEEE Standard C37.20.4■■ANSI C37.58■■ANSI C37.22■■NEMA SG6■■Canadian Standards CAN/CSA C22.2No. 193 and CAN/CSA C22.2 No. 58Load interrupter switches should notbe used to interrupt load currents abovetheir interrupting rating of 600 A, asthey are not designed nor tested forinterrupting fault currents on electricalsystems . Optional fuses can be providedfor phase overcurrent protection .3838150150600–1200600–12004050.46581.92531.5Switch MechanismThe quick-make, quick-break mecha n ism uses a heavy-duty coil spring that provides powerful opening and closing action. T o close the switch, the handle is inserted into the spring charging cam, then rotated upward through an angle of 120 degrees. This action charges the operating spring, as the mechanism is forced past toggle. The stored energy of the spring is released and transferred to the main shaft that snaps the switch closed.As a result of the over-toggle action, the blades are moved independently of the operator. It is impossible to operate the switch into an intermediate position.To open the switch, the handle is inserted into the spring charging cam and rotated downward through 120 degrees resulting in charging of the operating spring,then releasing its stored energy in similar sequence.Quick-Break DE-ION Arc InterruptionWith the switch closed, both main andauxiliary (flicker) blades are closed, andall of the current flows through the mainblades. T he flicker blades are in the closedposition in the arc chutes, but are past thearcing contacts and thus carry no current.As the main blades open, current istransferred momentarily to the flickerblades, which are held in the arc chutesby high pressure contact fingers. T hereis no arcing at the main blades.When the main blades reach a pre-determined angle of opening, a stoppost on the main blades prevents furtherangular movement between the mainand flicker blades. T his starts the flickerblades out of the high pressure contactsin the arc chutes and as contacts arebroken, the flicker blades are snappedinto position by their torsion springs.The heat of the arc, meanwhile, releasesa blast of de-ionizing gas from thegas-generating material of the arc chute.This combination of quick-break andDE-ION action quickly extinguishes thearc and the circuit is safely de-energized.A non-fused switch has the ability to closeand latch four times when rated 40 kA,and one time when rated 61 kA, andcontinue to carry rated current thusadding a large margin of integrity tothe electrical system.Bus Insulation SystemAll bus runs are supported using a highstrength and high creep, finned supportproviding in excess of 24.00 inches(609.6 mm) for 38 kV, of creep distancebetween phases and ground. T he moldedhigh track-resistant fins are constructedas standard of Aramid nylon or optionalCycloaliphatic epoxy.■■Significantly superior bus bracingthan standoff type A20 insulators■■Significantly increased creep distancephase-to-phase and phase-to-ground■■Improved endurance fromfault incidents■■Minimizes bus system failures dueto tracking■■Eliminates additional groundplanes in the switchgear for bussupporting systemsBus SupportFigure 8.3-1. Switch OperationBoth Blades Disengaged Main, Flicker BladesEngagedMain Blades Disengaged,Flicker Blade EngagedDuplex Switch ConfigurationTwo MVS load interrupter switch sections can be used to provide cost- effective source selectivity with a common load side bus feeding one load (fused or nonfused). Key interlocks are a standard feature provided to per m it only one switch to be closed at a time and prevent opening any switch door unless both switches are open.Figure 8.3-2. Typical Duplex Switch Configuration with One K1 Key— Dimensions in Inches (mm)Loadbreak Switch with Grounding Jaw The loadbreak switch can be supplied with optional grounding jaws for auto-matic grounding of the load circuit. When the switch is opened, the switch main blades engage grounding jaws to ground the load circuit. This feature cannot be used in a duplex switch configuration . The ground jaw option is available at38 kV. It is meant for applying a static ground, and is not rated for carrying fault currents.Figure 8.3-3.

T ests were performed to substantiate all published ratings in accordance with ANSI, IEEE, CSA and NEMA standards.The testing program included tests of:■■Basic impulse levels■■Momentary withstand■■Short-time withstand■■Fault closing■■Load interrupting at various loads, various power factors■■Mechanical life tests■■Temperature rise testThese tests verified not only the per-formance of the switch and integrated switch-fuse assembly, but also the suitability of the enclosure venting, rigidity and bus spacing.The mechanical life test subjected the MVS switch to a number of no load cycles greater than the requirements tabulated in ANSI C37.22 standards. T here were no moving or current carrying part failures as a result.The Fault Close and Load Interrupting test demonstrated significant improved performance above ANSI/IEEE standards. See T able 8 .3-3 and T able 8 .3-4 for results.38381501506006004050.46581.92531.5386005538384050.46581.91111a When RBA expulsion fuses are used, and two ratings appear, the lower rating applies when thelower-rated switch (15 kV, 40 kA fault close, 25 kA short-time current) versus the higher rating that applies when the higher-rated switch (15 kV, 61 kA fault close, 38 kA short-time) is used.Motor Operated MVSApplicationEaton’s MVS Pow-R-Drive E motor operator makes possible the safety and convenience inherent in remote switch operation.Motor Operated MVS Switch DescriptionA MVS Pow-R-Drive motor operatedswitch is a standard, manually operatedswitch in combination with a heavy-dutyelectric motor-driven linear actuator thatcharges the spring. T he linear actuator islocated in a separate isolated low-voltagecompartment. During electrical operation,it smoothly and quietly extends orretracts the proper distance to cause theswitch mechanism to operate.Standard motor operators are mounted inthe switch enclosure. T his eliminates theneed for a separate motor compartmentconserving floor space.Manual Operation OverrideManual OperationTo operate manually, loosen the holdingscrew that keeps the pin connecting thelinear actuator to the mechanism, andremove the pin. Remove the clevis pinon the support of the bottom of the linearactuator. Unplug the cord from thedisconnect i ng terminal block as theactuator is removed and set the actuatoraside. T he switch can now be operatedmanually with the removable handle.Lock Open Key InterlockA keyed lock is standard to lock the switchin the open position only.This lock not only locks the switch in theopen position, but also breaks theelectrical motor contacts integral to themotor control circuit and permits the keyto be removed. With the key, the operatorcan then open the lock on the switch door.This scheme gives positive assurance thatthe switch is open and cannot be closedwith the door open.MeteringElectronic Metering and Communications ApparatusMVS switchgear assemblies can be equipped with Eaton’s family of Power Xpert T and IQ digital meters to monitor a power circuit’s electrical quantities within the capabilities of each device. Eaton’s power management products provide hardware and softwaresolu t ions that allow customers to interface with their switchgear at varying levels of sophistication. Power Xpert and IQ Meters monitor common electrical parameters and communicate the data via standard industry protocols and optional web interfaces. Power Xpert Gateways consolidate devices into a single web browser interface and provide Ethernet connectivity. Eaton’s Foreseer web-based software system can display, analyze and store data from multiple devices across the facility to enable management of the customer’s power system.Electronic Metering Outdoor Enclosures Weatherproofing complying with the requirements of IEEE standard C37.20.3 is available for MVS switch g ear assemblies. The weatherproofing consists of sloped roof panels that are joined together with caps. Doors and rear covers are fully gasketed. Externally accessible louvered filtered covers, top and bottom, front and rear, are provided for ventilation. At least one 250 watt heater is provided in each vertical section. Power for the heaters may be supplied from an external source, or an optional integral control power transformer may be specified to provide power for the heaters.Outdoor EnclosurePower Xpert MeterPXM 4000/6000/8000IQ 130/140/150/250/260Automatic Transfer ControlT wo-Switch Automatic T ransferApplicationEaton’s MVS switchgear with an automatic transfer control system is an integrated assembly of motor operated MVS switches, sensing devices and control components. Available in 38 kV class.It is typically applied where the continuity of service for critical loads from two power sources in either a main/main or a main/ tie/main configuration is desired.MVS switchgear with an automatic transfer control system can meet most automatic throwover requirements as it has a wide variety of operational sequences embodied in one standard automatic transfer control system. Please note that the duty cycle of load interrupter switches is limited by ANSI Standard C37 .22 . Refer to T able 8 .3-3for maximum number of switching operations allowed . If the number of switching operations is expected to exceed the maximum allowed, then load interrupter switches should not be used . Use circuit breakers (refer to T ype MSB, MEB, MEF or V CP-W switchgear designs) . Also note that the operating times of Eaton’s motor operated load interrupter switches are much longer compared to circuit breakers, therefore, the switches are not suitable for closed-transition transfer applications . Use circuit breakers if closed-transition transfer is required . T ypical T wo-Switch AutomaticT ransfer Using ATC ControllerEaton’s ATC-900 controller continu o uslymonitors all three phases on both sourcesfor correct voltages. Should the voltageof the normal source be lost while thevoltage of the alternate source remainsnormal, the voltage sensing function inthe ATC controller will change statestarting the time delay function. If thevoltage of the normal source is notrestored by the end of the time delayinterval, the normal switch will open andthe alternate source switch will close,restoring power to the load.ATC ControllerEaton’s ATC controller is equipped todisplay history information via the frontpanel. ATC-900 controller stores 320 timestamped events. Oscillographic data forlast 10 events can be downloaded via theUSB port or displayed in the controller’sdisplay window. T he controller allowscommunications via RS-232 or Modbusthrough RS-485 port, Ethernet or viaUSB interface.ATC ControllerStandard Features■■Voltage sensing on both sources isprovided by the ATC controller■■Lights to indicate status of switches,sources, etc.■■Interlocking to prevent paralleling ofsources via software■■Control power for the automatictransfer control system is derived fromthe sensing voltage transformers■■Manual override operation■■Open transition on return to normal■■Programmable time delays on bothsources, “OFF DELA Y” and “ON DELA Y”■■Four programmable digital inputsand outputs■■Single-source responsibility; all basiccomponents are manufac t ured by Eaton■■Key interlocking of operating systemand doors where required to provideoperator safetyOptional Features■■Lockout on phase and/or groundovercurrents and/or internal bus faults■■Blown fuse overcurrent lockout■■Load current, power and PF meteringwith optional dcT module■■24 Vdc control power input■■Up to four additional I/O modules, eachwith four programmable digital inputsand digital outputsSurge ProtectionIEEE standard C62.11 for Metal Oxide Surge Arresters lists the maximum rated ambient temperature as 40 °C. T he ambient temperature inside an Eaton MVS switchgear vertical section may exceed this temperature, especially in outdoor applications where solar radiation may produce a significant contribution to the temperature. T able 8 .3-6 lists the recommended minimum duty cycle voltage rating for various system grounding methods. Surge arrester rating is based upon the ambient air temperature in the switchgear vertical section not exceeding 55 °C.33.0034.50 38.0027303022.0024.4024.403030—24.4024.40———————27303022.0024.4024.4036363629.0029.0029.004548—36.5039.00—Note: MCOV = Maximum Continuous Operating Voltage.System OptionsPartial Discharge Sensing and Monitoring for SwitchgearPartial Discharge in SwitchgearPartial discharge (PD) is a common name for various forms of electrical discharges such as corona, surface tracking, and discharges internal to the insulation. It partially bridges the insulation between the conductors. T hese high frequency discharges are essentially small arcs occurring in or on the surface of the insulation system when voltage stress exceeds a critical value. With time, airborne particles, contaminants and humidity lead to conditions that result in partial discharges. Partial discharges start at a low level and increase as the insulation becomes deteriorated. Examples of partial discharge inswitchgear are surface tracking across bus insulation, or discharges in the air gap between the bus and a support (such as where a bus passes through an insulating window between the sections of the switchgear). If partial discharge activity is not detected and corrected, it can develop into a full-scale insulation failure followed by an electrical fault. Most switchgear flashover and bus failures are a result of insulation degradation caused by various forms of partial discharges.Sensing and MonitoringEaton’s T ype MVS metal-enclosedswitchgear (2.4–27 kV) is corona-free by design. By making switchgear assemblies corona-free, Eaton has made its standard switchgear more reliable. However, as indicated above, with time, airborne particles, contaminants and humidity lead to conditions that cause partial discharges to develop in switchgear operating at voltages 4000 V and above. Type MVS switchgear can be equipped with factory-installed partial discharge sensors and a partial discharge sensing relay for continuous monitoring under normal operation. T imely detection ofinsulation degradation through increasing partial discharges can identify potential problems so corrective action can be planned and implemented long before permanent deterioration develops. Partial discharge detection can be the foundation of an effective predictive maintenance program. T rending of partial discharge data over time allows prediction of failures, which can be corrected before catastrophic failure occurs.The PD sensing and monitoring system consists of Eaton’s InsulGard T relay and PD sensors, specifically developed for application in the switchgear to work with the relay. T here are two types of PD sensors used in the switch g ear: the first sensor is a coupling capacitor type sensor developed for use with 5 kV, 15 kV and 27 kV switchgear.The coupling capacitor sensor detects partial discharges within the switchgear cubicle and/or adjacent cubicles, and is typically installed on the load side of the feeder switches or on the main bus. T he second sensor is a small donut type radio frequency current transformer (RFCT). It is designed for installation around the ground shields of incoming or outgoing power cables. It detects partial dis c harges in power cables and monitors for external electrical noise.Typically one set of coupling capacitor sensors is used at every two cubicles. One RFCT sensor is used for each incoming and outgoing power cable circuit.Output signals from sensors (coupling capacitor and RFCT) are wired out to terminal blocks for future or field use, or connected to the InsulGard relay. One InsulGard relay can monitor up to 15 input signals, as well as temperature and humidity. T he temperature andhumidity sensors are included with each InsulGard relay system. T he relaycontinuously monitors the switchgear primary system for partial discharges and provides an alarm signal (contact closure) when high PD level is detected. Also, data analysis and diagnostics by Eaton engineers can also be provided by remote communication with the InsulGard relay.The sensors and InsulGard relay are optional in MVS switchgear .Figure 8.3-5.

Layouts shown are for rear-accessible equipment . Front-accessible designs are available—refer to Eaton . Many other configurations and combinations are available. T wo voltage transformers for metering and one control transformer for auxiliary power can be mounted in the structures shown. For control power above 1 kVA, additional space is required. Depth of units will vary due to cable entrance and exit requirements, the addition of lightning arresters, instrument transformers, special cable terminators, etc. Cables are shown out top and bottom for layout only. T op or bottom must be selected for incoming and for outgoing cables. Cable sizing is based on two 500 kcmil XLP or EPR insulated cables per phase using preformed slip-on cable termination devices.Note: Width for Utility Metering Structures may vary.ATC = Automatic T ransfer Controller (see Page 8 .3-9)M = Motor OperatorPLC = Programmable Logic ControllerNote: Not to be used for construction purposes unless approved.Figure 8.3-9.

Satisfy the conditional equation below.Where the maximum detectable piston speed = V (mm/s)V (mm/s) =Travel of auto switch (mm)X1000 Change over time of load (ms)•Reserve a space for maintenance.Remember to leave space for maintenance when installing the product.•Product handling∗Installation•Follow the specified tightening torque. (0.05 to 0.10 N•m)Excessive tightening torque can break the mounting screws, mounting bracket or Auto switch.Insufficient tightening torque can displace the Auto switch from the original position.(Refer to the installation manual)•Connect frame-ground terminal (FG terminal) to the ground when using a switching power supply. •Do not drop, hit or apply excessive shock (larger than 1000 m/s2) to the Auto switch.Otherwise it can result in damage to the Auto switch causing failure or malfunction.∗Wiring•Do not pull the lead wires.Especially never lift actuator equipped with Auto switch by holding the lead wires.It can result in damage to inside of Auto switch causing malfunction.•Do not bend or apply tensile stress to lead wires repeatedly.Wiring with repetitive bending stress or tensile stress can cause peel of a sheath.If the lead wire can move, fix it near the body of the Auto switch.A bend radius of about 40 to 80 mm is recommended. Contact us for the details.•Connect wires and cables correctly.Miswiring can break the Auto switch depending on the miswired circuit.•Do not connect wires while the power is on.Otherwise it can break the circuit inside the Auto switch causing malfunction.•Do not lay wires or cables with power cable or high-voltage cable in the same wiring route.Lay the wires to the Auto switch to a wire duct or in a protective tube other than those for power cables orhigh-voltage cables to prevent contamination with noise or induced surge voltage from power lines or high-voltage lines.•Verify the insulation of wiring.Poor insulation (interference with other circuit, poor insulation between terminals and etc.) can introduce excess voltage or current to the Auto switch causing damage.•Keep wiring as short as possible to prevent contamination from noise and induced surge voltage.Do not use a cable longer than 100 m.∗Environment•Never use the product for a corrosive gas or liquid.It can cause failure or malfunction.•Do not use the product in a place where strong magnetic field exists.It can cause a malfunction of the Auto switch, or demagnetization of a magnet inside actuator.•Do not use the Auto switch in an environment where the Auto switch is always splashed with water drips.It can cause poor insulation or malfunction due to swelling of a resin filled inside the Auto switch.•Do not use the product in an atmosphere containing oils or chemicals.Use of the Auto switch in an atmosphere containing various oils or chemicals such as coolant or detergent can result in giving bad influence (poor insulation, malfunction die to swelling of a resin filled inside the Auto switch, or hardening of lead wires) even if in a short operating period.•Do not use the product in an atmosphere where steel dusts accumulate or magnetic bodies are gathered closely.When an amount of steel chips or steel dusts such as sputters of welding accumulate around an actuator equipped with Auto switch, or magnetic bodies (those attracted by magnet) are gathered closely to the actuator, they can weaken a magnet inside the actuator causing inoperativeness of the Auto switch.•Do not use the product in an environment where heat cycle exists.Heat cycles other than ordinary change of the temperature can affect the inside of Auto switch.•Do not use the Auto switch nearby a place where electric surges are generated.Internal circuit elements of Auto switch can deteriorate or break when equipment generating a large surge (electromagnetic lifter, high frequency induction furnace, motor, etc.) is located near the Auto switch. Provide surge preventives, and avoid interference.•Do not use a load generating surge voltage.Use Auto switch equipped with surge absorber when a surge-generating load such as a relay or solenoid valve is driven directly.•Do not use in environments subject to radiation stress.It is not designed to withstand radiation, which may cause damage to the internal circuit elements of the auto switch.∗Adjustment and Operation•Adjust an Auto switch in the middle of operating area and then fix it.Adjust the position of Auto switch in a way that a piston stops at about the middle of operating area (where switch is in ON status).Mounting the Auto switch close to the end of operating area can cause instability of operation.Air grippers and rotary actuators have their own setting method. Follow their instructions.•Turn the power on after connecting a load.Otherwise it can cause excess current causing instantaneous breakage of the Auto switch.∗Maintenance•Perform maintenance and check regularly.Otherwise safety is not assured due to an unexpected malfunction or incorrect operation.•Do not touch terminals or printed circuit board inside the switch while the power is on.Otherwise it can cause in malfunction or damage to AUTO switch.∗Others•Contact SMC for water-proof capability, endurance of wire bending or use at welding shop. •Contact SMC when there is a problem of switch’s ON/OFF positions (hysteresis).D-Output typeSymbol SpecificationN 3-wire, NPNP 3-wire, PNPB 2-wireElectric entrySymbol SpecificationNIL In lineV Perpendicular•D-M9BA/M9NA/M9PA•D-M9BAV/M9NAV/M9PAV■InstallationWhen mounting the Auto switch to actuator it should be done with clamp for actuator.“How to mount” depends on actuator type and tube I.D. Please refer the actuator catalogue.When the Auto switch is mounted newly, please prepare the clamp for actuator after confirms that the actuator built in magnet.•Proper tightening torqueUse a watchmaker driver whose grip diameter is 5 to 6 mm when tightening the mounting screw.M2.5 mount screw tightening torque range shall be 0.05 to 0.10 N•m (0.5 to 1.0 kgf•cm)•Setting the detecting positionSet the actuator at the stroke end. Set the switch in the area to where the auto switch red lamp light.(Detecting actuator end)Based on A and B dimensions in the actuator catalogue, set the switch.For actual installation works, perform adjustment with checking the operating conditions of the Auto switch.Air grippers and rotary actuators have their own setting method.

成都奥托尼克斯温控器说明书1.接通智能温控器的电源，显示屏上显示的是当前的温度。

因为传感器未接触其他器件，而是直接暴露在空气中，所以这就是现在的气温：31摄氏度，还不算太热。

2.显示屏右下方是“启动温度”设置按钮，按升温键一下，温度提高1摄氏度；也可以按住不放手，温度连续升高。

这里我设置为65摄氏度，也就是传感器温度低于或等于65度时，输出插座自动通电，所连接的设备启动。

设备可以是电动机、电加热器等等。

3.显示屏左下方是“停止温度”设置按钮。

我设置为80度，即传感器温度高于或等于80度时，输出插座自动断电，受控设备停止工作。

4.再看温度传感器，它的作用是感知被监测对象的温度，并转变为电信号，通过导线传回温控器。

可以拿一个铁质物品试一下，传感器有较强磁性，能吸附其上。

5.现在，把传感器吸附在被监测的设备上。

当然，这个设备得有铁质部分；否则，就得想办法固定了。

6.把受控设备的插头插在温控器输出插座上。

注意：最好在温控器本身未加电的状态下进行。

至此，设置工作完成，温控器加电，该系统就开始工作了。

注意事项：必须明确温控器的输出功率，受控设备的电功率必须小于这个指标。

1.设定温度：按SET键可设定或查看温度设定点。

按一下SET键数码管字符开始闪动，表示仪表进入设定状态，按△键设定值增加，按▽键设定值减小，长按△键或▽键数据会快速变动，再一次按SET 键仪表回到正常工作状态温度设定完毕。

2.回差控制（XMT201-C）：按SET键3秒仪表进入内层参数设定状态。

第一个出现并闪动的参数为C00即回差值，回差控制参数要慎重调整，仪表控制加热输出值到设定值，当温度下跌到设定值减回差值时又开始加热，在回差范围内输出（继电器）是不动作的，这样可减少继电器动作次数以利延长继电器寿命。

例：若设定值是80.0℃，回差为0.5，仪表控制加热到80.0℃时继电器释放，温度下跌到80.0℃-0.5℃=79.5℃时继电器又吸合。

回差值越大继电器动作次数越少，回差值过大会降低控制精度。
