It is simple that the purpose of this utility model provides a kind of wiring, but random installation or remote the installation, and volume is little, in light weight, can be subjected to the monophase machine spirally-controlled switch that stall is restarted and winding and bidirectional triode thyristor are started in protection when transship at motor.
The purpose of this utility model is achieved in that
A kind of monophase machine spirally-controlled switch, comprise a box body, box body is provided with fairlead, fixing hole and terminal screw, be provided with bidirectional triode thyristor in the box body, trigger electronic components such as resistance, relay, thermal relay, electric capacity, diode, the electronic component that is fixed in the box body is passed by fairlead through lead, is connected with motor through terminal screw.
Described monophase machine spirally-controlled switch is separated with insulating material between thermal relay and the bidirectional triode thyristor fin, and is connected and fixed on radiator by hold-down screw.
Described monophase machine spirally-controlled switch, triggering resistance one end is connected with the control utmost point G of bidirectional triode thyristor, the other end connects with the anode A and the electric motor starting electric capacity of bidirectional triode thyristor respectively through moving contact, the thermal relay of relay successively, the starting capacitance other end connects current rectifying and wave filtering circuit through decompression capacitor, supplies with the relay working signal by current rectifying and wave filtering circuit.
Described monophase machine spirally-controlled switch, current rectifying and wave filtering circuit is made up of two diodes (9,10) and an electric capacity.

Described monophase machine spirally-controlled switch, the monophase machine spirally-controlled switch is installed and fixed through fixing hole by fixture.
The utility model compared with prior art, electronic component is fixed in the box body, volume is little, connects conveniently through fairlead and terminal screw, installs simply, and is provided with protective circuit, prevents that motor from playing burning out of winding and bidirectional triode thyristor, performance is good, cost is low.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the circuit diagram that the utility model connects with motor.
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.
