2. 母联可以根据要求，相应选择 NA, HA, HF 型的 MT 负荷开关。
根据保护配置和测量功能要求不同，MIC 控制单元型号也将随之改变。

Cutting the energy supply is avoided with zero risk for the operator.The plug and socket connection cuts cost installation as well as in-situ wiring errors. ESSAILEC is ideal for the wiring of sub-assemblies in the secondary circuits.ESSAILEC terminal blocksProtection relays,Protection relays,Testing :The ESSAILEC socket supplies energy to the protection or counting devices. The insertion of the test plug, which is connected to the measurement equipment, allows the testing of the devices, without perturbing the circuit.ESSAILEC blocks are well adapted to current or voltage measurement :-Current sockets with make before break contacts and pre-wired test plug for current measures-Voltage sockets with open contacts and pre-wired test plug for voltage measures-Up to 4 ammeters or 4 voltmeters connected to the test plugDistributing :The ESSAILEC plug is continuously mounted on the socket to supply current or voltage to secondary circuits sub assemblies.ESSAILEC blocks extreme versatility allow :-Safe current distribution with current socket with mobile contacts since the secondary circuit is not cut when plug is removed-Voltage or polarity distribution with dedicated voltage or polarity socket with closed contactESSAILEC is designed to offer :Great flexibility :-Connection multi contacts « plug and play »-Panel, rail, rack fixed mounting or stand-alone connector -Two wiring technologies, up to 10 mm²Extreme reliability :-Non symmetric blocks -Coding accessories -IP20 design -Locking system -Sealed coverR S T NFor technical characteristics and complete part numbers list, please ask for the ESSAILEC catalog10005006003225254 mm 21.65 mm²12 AWG 13 mm / .51"IECB.SCSANFC DINTS 50-180.5 - 0.8 Nm /4.4 - 7.1 Ib.in0.2 - 422-12 AWG0.22 - 40.5 - 1.50.28 - 1.6580050060041252562.512 AWG 13 mm / .51"0.8 - 1 Nm / 7.1 - 8.9 Ib.inIECB.S CSANFC DINTS 50-180.5 - 1020-12 AWG0.5 - 60.28 - 2.590050060046406510 mm 26 mm² 6 AWG 14 mm / .55"IECB.S UL/CSANFC DINTS 50-181.2 - 1.4 Nm / 10.6 - 12.3 Ib.in0.5 - 1620 - 6 AWG0.5 - 100.28 - 6M 4/6.RS - 4 mm² blocks - 6 mm .238" spacingCharacteristicsWire size mm² / AWGVoltage V CurrentARated wire sizemm² / AWG Wire stripping lengthmm / inches Recommended torque (screw)Nm / Ib.inSolid wire Stranded wire Solid wire Stranded wire Screw clampLugsM 6/8.RS - 6 mm² blocks - 8 mm .315" spacingCharacteristicsWire size mm² / AWGVoltage V CurrentARated wire sizemm² / AWG Wire stripping lengthmm / inches Recommended torque (screw)Nm / Ib.inSolid wire Stranded wire Solid wire Stranded wire Screw clampLugspending M 10/10.RS - 10 mm² blocks - 10 mm .394" spacingCharacteristicsWire size mm² / AWGVoltage V CurrentARated wire sizemm² / AWG Wire stripping lengthmm / inches Recommended torque (screw)Nm / Ib.inSolid wire Stranded wire Solid wire Stranded wire Screw clampLugspending SelectionAccessories(1) Only for block M 4/6.RS (4) For blocks M 4/6.RS and M 6/8.RS(2) Only for block M 6/8.RS(3) Only for block M 10/10.RSDR 1,5/4 - 1.5 mm² blocks - 4 mm .157" spacingDR 1,5/5... - 1.5 mm² blocks - 5 mm .200" spacing。
施耐德断路器选择1进线和分段断路器－空气断路器1.1一般规定变压器容量S≤800kV A，断路器选用MT06~16N 分断能力I cu=I cs=50kA, I cw=36kA (1s)控制单元选用Micrologic 5.0A变压器容量S ≥1000kV A，断路器选用MT20~40H1-H2分断能力I cu=I cs=65-100kA,I cw=65-85kA (1s)控制单元选用Micrologic 5.0A1.2应用举例配电变压器S9-630KV A, 4.5%,二次侧额定电流I n2＝909A，最大工作电流I2max＝957A，二次侧最大三相短路电流I k＝17.91kA，最小16.2kA1.2.1进线断路器选用MT12N2, 1250A,4P空气断路器,额定电流I n＝1250A(1)过载长延时保护－反时限，t＝k/I2整定电流：I r=1.05×957=1005A,取I r=0.8I n=1000A（整定范围500 ~ 1250A）即0.4~1.0I n长延时整定时间(6I r的动作时间)要与以下条件配合：1)应躲过最大一台电动机起动时间，或自动再起动时间；2)变压器二次侧最大短路时，过载保护动作时间不小于0.4s，即K=179102⨯0.45=(6⨯I r)2⨯t r=60002⨯t r得t=4.01s取t r＝4 s或t r＝8 s（级差为4s）当变压器过载1.3倍，即I=1.3⨯957=1244A时，若t r=4s保护动作时间：t=(60002⨯4)÷12442=93 s 可见，太保守－完全没有发挥变压器的过载能力取t r=8s(2)短路短延时保护整定电流I sd的整定应取以下两种情况最大者：1）一台变压器带总负荷（不含最大电动机负荷）加上最大一台电动机的起动电流；2）一台变压器带50％总负荷，加上另一段母线上电动机自动再起动电流；有时，为了简化计算，可取2.0~2.5倍变压器额定电流，即认为变压器最大尖峰电流不超过额定电流的2~2.5倍。
