Operation principle of the present utility model is as follows:
As Figure 10, shown in Figure 18 and Figure 26, when change over switch SA pushes remote control position, system is by multifunctional measurement and control module 1PD, 2PD, 3PD controls inlet wire bus connection switch, in addition as shown in Figure 1, multifunctional measurement and control module 1PD, 2PD, the voltage that 3PD also can will collect, electric current and inlet wire bus connection switch 1QF, 2QF, the electric network informations such as the switch state of 3QF, automatic safety device is uploaded to by bus communication system, automatic safety device passes through the real-time grid amount of information collected, carry out computational analysis, accurately can judge power supply status, and implement Switching power, and there is on-line operation Stateful Inspection, Long-distance Control and event recording function.
As shown in Figure 10, Figure 18 and Figure 26, when change over switch SA pushes manual position, system controls inlet wire bus connection switch 1QF, 2QF, 3QF at switch cubicle scene by button 1SB1,1SB2,2SB1,2SB2,3SB1,3SB2, when change over switch SA pushes zero-bit, lockable all operations.
When change over switch SA push haul oneself willingly into runback position time, as shown in Figure 1, under normal circumstances, service entrance switch 1QF and 2QF is in closure state, bus connection switch 3QF is in off-state, and as shown in Figure 6, the coil being arranged on voltage relay 1KV1,1KV2 of inlet wire side is always charged.If due to transformer tripping operation or after other reasons makes incoming power decompression, voltage relay 1KV1, normally-closed contact is closed separately due to decompression for 1KV2, time relay 1KT1 coil obtains electric, as shown in Figure 10, the timing closing of time relay 1KT1 normally opened contact, fault side service entrance switch 1QF is tripped, auxiliary relay 1KA1 and time relay 1KT3 coil losing electricity simultaneously, as shown in figure 11, auxiliary relay 1KA1 normally-closed contact resets closed, auxiliary relay 1KA3 coil obtains electric, after starting prepared auto restart, the time delay of time relay 1KT3 normally opened contact disconnects, as shown in figure 26, auxiliary relay 1KA3 normally opened contact closes, bus connection switch 3QF is closed a floodgate, prepared auto restart process completes.After faulty line voltage resume is normal, as shown in figure 11, voltage relay 1KV1,1KV2 obtain electric closed due to the normal normally opened contact separately of voltage resume, time relay 1KT2 and auxiliary relay 1KA4 coil obtain electric, as shown in figure 26, auxiliary relay 1KA4 normally opened contact is instantaneous closed, make bus connection switch 3QF separating brake, as shown in Figure 10, the timing closing of time relay 1KT2 normally opened contact, service entrance switch 1QF is closed a floodgate, and runback process completes, it is identical with 1# inlet wire that 2# inlet wire hauls oneself willingly into runback process, see Figure 18, Figure 19 and Figure 26.
When change over switch SA push haul oneself willingly into not runback position time, as shown in Figure 10, Figure 18, Figure 26, by the sub-gate circuit locking of change over switch SA by the closing circuit bus connection switch 3QF of service entrance switch 1QF or 2QF, make it carry out runback operation.
Only have after working power is reliably disconnected, stand-by power supply could drop into, and prevents stand-by power supply He Zhong Library, improves the success rate of backup auto-activating device action.Whether backup auto-activating device through time delay, no matter the tripping of work circuit breaker, first can send out the order of jumping work circuit breaker after working power dead electricity.After judging reliable tripping according to its auxiliary contact, then close stand-by power supply.
Prepared auto restart except the service entrance switch power supply of reliable tripping fault side, also can join the non-ensured load cut on working bus bar before closing stand-by power supply.As shown in figure 26, when prepared auto restart starts, auxiliary relay 3KA3 coil obtains electric, is then connected to non-ensured load control loop by the normally opened contact of the auxiliary relay 3KA3 shown in Figure 29, and non-ensured load is tripped when prepared auto restart drops into.
Prepared auto restart, except possessing corresponding locking, prevents outside misoperation, also possesses the function of fail lockout prepared auto restart, and as shown in figure 26, when circuit overload, control loop disconnects by auxiliary relay 3KA1, makes prepared auto restart cannot act on inlet wire and bus connection switch.
The utility model autogamy electrical source exchange function, as shown in figure 28, when any road inlet wire has electricity, power line L01 and N01 has electricity, controls power supply guarantee for this system provides.
