To control the investment and disconnection of alternating current.
The working principle of the utility model are as follows:
Referring to Fig. 1, (1) closes circuit breaker Q F1, QF2 and QF3；(2) when the normally closed touching of change-over switch SA1 and contactor KM
In the closure state, alternating current is put into point, and the coil of contactor KM1 and contactor KM3 obtain electric, the normally opened contact of contactor KM1
Closure, indicator light HR1 is bright, and the normally-closed contact of contactor KM1 and the normally-closed contact of contactor KM3 disconnect, the coil of contactor KM2
It cannot obtain electric, the normally opened contact of contactor KM2 disconnects, and backup power source is not put into, and indicator light HR2 goes out；(3) it if mains failure, connects
The normally opened contact of the coil losing electricity of tentaculum KM1 and contactor KM3, contactor KM1 disconnects, and indicator light HR1 goes out；Contactor KM1 and
The normally-closed contact of contactor KM3 is closed, and the coil of contactor KM2 obtains electric at this time, the normally opened contact closure of contactor KM2, instruction
Lamp HR2 is bright, and alternate power autocast is load supplying；(4) if city power recovery, system mode automatically switches to (2) step
State；(5) to force to be switched to backup power source power supply in the case where alternating current has electricity condition, then change-over switch SA1 is pushed disconnection
The normally opened contact of state, the coil losing electricity of contactor KM1 and contactor KM3, contactor KM1 disconnects, and indicator light HR1 goes out；Contact
The normally-closed contact of device KM1 and contactor KM3 closure, the coil of contactor KM2 obtains electric at this time, and the normally opened contact of contactor KM2 closes
It closes, indicator light HR2 is bright, and in-put of spare power supply is load supplying；(6) when alternating current works, button switch SS1, button switch are pressed
SS1 is disconnected, the coil losing electricity of contactor KM1, then the normally opened contact (main contacts) of contactor KM1 disconnects, and stops powering load,
But since the coil of contactor KM3 does not have power loss, contactor KM2 is not put into, then presses button switch SS1, and button is opened
It closes SS1 to reset, normally opened contact (main contacts) investment of contactor KM1 continues powering load.(7) it when standby electricity works, presses
Button switch SS2, button switch SS2 are disconnected, then the normally opened contact (main contacts) of contactor KM2 disconnects, and stop powering load,
Because alternating current is without electricity, contactor KM1 is not put into, then presses button switch SS2, and button switch SS2 resets, and contactor KM2's is normally opened
Contact (main contacts) investment, continues powering load.(9) by X1-X6 dry contact signal (X1-X6 is the second connecting terminal, the
Two connecting terminals at least 6 pins), it can be with remote monitoring system working condition.(10) function of KM is that optionally (KM's is normal
Closed contact can be the normally-closed contact of contactor, relay or button switch), concrete function is received by the first connecting terminal
External remote signal is disconnected, contactor KM1 and contact by the normally-closed contact of external remote signal control switch KM
The normally opened contact of the coil losing electricity of device KM3, contactor KM1 disconnects, and indicator light HR1 goes out, and alternating current is not put into, and indicator light HR2 is bright, standby
It is put into power supply, therefore the effect of KM is that the switching of alternating current and backup power source is controlled by remote control signal.
In conclusion the present embodiment has the function of the backup power source power switching of alternating current and emergency, has the machine pressure and cut
Function is changed, has long-range control handoff functionality, has state-indicating function, while also can provide necessity to route by fuse
