Working principle of the present invention is as follows：

As shown in Figure 10, Figure 18 and Figure 26, when change-over switch SA pushes remote control position, system can pass through multifunctional measurement and control Module 1PD, 2PD, 3PD control inlet wire bus connection switch, in addition as shown in Figure 1, multifunctional measurement and control module 1PD, 2PD, 3PD The electric network informations such as the switch state of collected voltage, electric current and inlet wire bus connection switch 1QF, 2QF, 3QF can also be passed through Bus communication system uploads to automatic safety device, and automatic safety device is by collected real-time grid information content, carrying out Calculate analysis, can accurately judge power supply status, and implement Switching power, and with on-line operation Stateful Inspection, remote control and Event recording function.

As shown in Figure 10, Figure 18 and Figure 26, when change-over switch SA pushes manual position, system can by button 1SB1, 1SB2,2SB1,2SB2,3SB1,3SB2 control inlet wire bus connection switch 1QF, 2QF, 3QF at switchgear scene, work as conversion When switch SA pushes zero-bit, lockable all operations.

When change-over switch SA, which is pushed, hauls oneself willingly into runback position, as shown in Figure 1, under normal circumstances, service entrance switch 1QF and 2QF In closed state, bus connection switch 3QF is off, as shown in fig. 6, mounted on enter line side voltage relay 1KV1, The coil of 1KV2 charges always.If after making incoming power decompression due to transformer tripping or other reasons, voltage relay 1KV1,1KV2 due to decompression respectively normally-closed contact be closed, time relay 1KT1 coils obtain it is electric, as shown in Figure 10, time relay Device 1KT1 normally opened contact timing closings make failure side service entrance switch 1QF trip, while intermediate relay 1KA1 and time relay Device 1KT3 coil losing electricities, as shown in figure 11, intermediate relay 1KA1 normally-closed contacts, which reset, to be closed, and intermediate relay 1KA3 coils obtain Electricity, after starting prepared auto restart, the delay of time relay 1KT3 normally opened contacts disconnects, and as shown in figure 26, intermediate relay 1KA3 is normally opened Contact closure makes bus connection switch 3QF close a floodgate, and prepared auto restart process is completed.After faulty line voltage restores normal, such as Figure 11 institutes Show, voltage relay 1KV1,1KV2 obtain electric closure since voltage restores normal respectively normally opened contact, and time relay 1KT2 is in Between relay 1KA4 coils obtain electric, as shown in figure 26, intermediate relay 1KA4 normally opened contacts are instantaneously closed, and make bus connection switch 3QF Separating brake, as shown in Figure 10, time relay 1KT2 normally opened contact timing closings make service entrance switch 1QF close a floodgate, and runback process is complete It is identical as 1# inlet wires that runback process is hauled oneself willingly at, 2# inlet wires, referring to Figure 18, Figure 19 and Figure 26.

When change-over switch SA, which is pushed, hauls oneself willingly into not runback position, as shown in Figure 10, Figure 18, Figure 26, pass through change-over switch SA The sub-gate circuit of the closing circuit bus connection switch 3QF of service entrance switch 1QF or 2QF are latched, make it that can not carry out runback operation.

Only after working power is by reliable disconnect, stand-by power supply could be put into, and prevented stand-by power supply He Zhong Library, carried The success rate of high backup auto-activating device action.Backup auto-activating device after working power dead electricity through delay, though work breaker whether Tripping can first be sent out and jump work breaker order.After judging reliable tripping according to its auxiliary contact, then close stand-by power supply.

Before prepared auto restart closes stand-by power supply, in addition to the service entrance switch power supply of reliable tripping failure side, it can also join and cut on working bus bar Non-ensured load.As shown in figure 26, when prepared auto restart starts, intermediate relay 3KA3 coils obtain electric, then pass through Figure 29 institutes The normally opened contact of the intermediate relay 3KA3 shown is connected to non-ensured load control loop, makes non-ensured load when prepared auto restart is put into Tripping.

Prepared auto restart prevents malfunction outer, is also equipped with the function of fail lockout prepared auto restart, such as scheme except having corresponding locking Shown in 26, when circuit overload, intermediate relay 3KA1 disconnects control loop, makes prepared auto restart that can not act on inlet wire and mother Connection switch.

Autogamy power supply handoff functionality of the present invention, as shown in figure 28, when arbitrarily inlet wire has electricity all the way, power cord L01 and N01 has electricity, and control power supply guarantee is provided for the system.
