Embodiment
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model, is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
As shown in Figure 1, of the present utility model a kind ofly mainly consist of the following components without the earth leakage protective device (hereinafter to be referred as earth leakage protective device) of tripping operation power-off while carrying out leakage tests: protector input end, protector main switch, protector output terminal, protector main control chip, trip coil relay, detect reset switch, trip coil, electrical apparatus release, busy relay, phase change-over switch and test port, wherein protector input end, protector main switch, protector output terminal, protector main control chip, trip coil relay, trip coil, electrical apparatus release is the device in prior art earth leakage protective device.
Protector input end is connected with protector output terminal by protector main switch, and when protector main switch closes a floodgate, the power supply that self-shield device input end enters is delivered to protector output terminal through protector main switch, for being connected to the customer power supply of protector output terminal.Protector main switch is connected with protector main control chip, and the output terminal of protector main control chip is trip coil relay in parallel and busy relay simultaneously, and protector main control chip can be controlled trip coil relay and busy relay moves simultaneously.Trip coil relay is connected with trip coil by detecting reset switch, can be trip coil power supply after the trip coil actuating of relay, and reset detection switch can cut off the current supply circuit between trip coil relay and trip coil.Trip coil powers on and can drive electrical apparatus release action, realizes the action of protector main switch.Between busy relay and protector output terminal, be provided with phase change-over switch, test port is connected by the normally closed contact of busy relay and the moved end of phase change-over switch, and the not moved end of phase change-over switch is connected with protector output terminal.
As shown in Figure 2, coil KM1 is above-mentioned trip coil, and K switch 1 is above-mentioned detection reset switch, and K switch 1 is linked switch, is connected on the current supply circuit of coil KM1, can be switched on or switched off by Push switch K1 the current supply circuit of coil KM1.Coil KA1 is the coil of above-mentioned busy relay, is connected in parallel on the output terminal of protector main control chip with trip coil relay simultaneously.Normally closed contact KA1-1 one end of busy relay KA1 is connected with the moved end of switch K2; three of switch K2 not moved end be in parallel with three phase line A, B, C of protector output terminal respectively; the other end of normally closed contact KA1-1 is connected with test port S, and switch K2 is above-mentioned phase change-over switch.In actual earth leakage protective device; the not top of the coil KM1 of electrical apparatus release, the coil KA1 of busy relay and normally closed contact KA1-1 and switch K2 is all arranged on earth leakage protective device inside; the moved end of detecting reset switch K1, test port S and switch K2 is arranged on a side of the shell of earth leakage protective device, and convenient operation personnel manually operate.
