Be described further below in conjunction with the utility model:
The monophase machine spirally-controlled switch is fixed in the box body 1, and box body 1 is provided with several fairleads 13, fixing hole 14 and terminal screw 19.Be separated with insulating material 5 between thermal relay 4 and the bidirectional triode thyristor fin 7, be connected and fixed on radiator 20 by hold-down screw 3.Trigger the G utmost point of resistance 11 1 termination bidirectional triode thyristors, the other end connects with the A utmost point and the electric motor starting electric capacity 16 of bidirectional triode thyristor respectively through moving contact 17, the thermal relay 4 of relay 2 successively, and the other end of starting capacitance 16 connects current rectifying and wave filtering circuit through decompression capacitor 12.The K utmost point of one termination bidirectional triode thyristor 6 of motor main winding 15, the negative pole of electric capacity 8 in the other end of another termination starting winding 18 and the current rectifying and wave filtering circuit.Whole monophase machine spirally-controlled switch is installed and fixed through fixing hole 14 by fixture.
Behind power connection, there is electric current to pass through in the motor main winding 15, the G utmost point of while bidirectional triode thyristor 6 must be established by cable logical successively through triggering resistance 11, the moving contact 17 of relay 2, thermal relay 4, and starting capacitance 16 and starting winding 18 get electric, electric motor starting.The voltage of starting winding 18 two ends induction is by decompression capacitor 12 step-downs, supply with relay 2 operating voltages through current rectifying and wave filtering circuit, make moving contact 17 disconnect, the G utmost point dead electricity of bidirectional triode thyristor 6 and turn-offing, starting winding 18 loses starting current, and motor enters normal operation.
When motor is obstructed stall because of certain reason, the non-inductive voltage in starting winding 18 two ends, relay 2 dead electricity, moving contact 17 closures, bidirectional triode thyristor 6 conductings, starting capacitance 16 gets electric starting winding 18 and gets starting current, and motor is reset.In starting process; the big electric current of bidirectional triode thyristor 6 because of by electric motor starting the time generates heat; grow with time; radiator 20 and fin 7 obtain heat and give thermal relay 4 through insulation material 5 sensings; when reaching its working temperature, thermal relay 4 disconnects, and bidirectional triode thyristor 6 turn-offs; starting winding 18 no starting currents pass through, thereby reach the effect of protection starting winding 18 and bidirectional triode thyristor 6.
After the motor rotation blockage fault was got rid of, thermal relay 4 was resumed work because of former operating temperature hangs down within the several seconds, the motor operate as normal.
