Motivation.When power supply is normal, ac contactor coil obtain electric after, catalyst adhesive so that circuit ON or motor obtain electric fortune
Turn.After power supply is because of fault power-off, ac contactor coil dead electricity, catalyst disconnects, and after waiting power up normal, generally requires
Manually it is again started up catalyst.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that A.C. contactor fault power-off
Energising auto-start control circuit, simple in construction, easy to use, it is effectively increased work efficiency so that A.C. contactor fault again
After power-off incoming call, it is possible to realize automatic Power resumption.
Its technical scheme is: include 220V power supply, control circuit, insurance FU, start button S1, stop button S2, power-off
Time delay relay KT1, power cut off delay time relay KT2,220V power supply by insurance FU parallel connection A.C. contactor KM and
Connect respectively on power cut off delay time relay KT2, A.C. contactor KM and the power cut off delay time relay KT2 stop button
The two ends parallel connection power cut off delay time relay KT1, described stop button S2 and A.C. contactor KM of S2, A.C. contactor KM
Between series control circuit, described control circuit includes that start button S1, A.C. contactor KM auxiliary normally opened contact, power-off are prolonged
Time the time delay break contact of time relay K T1 and the timing closing contact of power cut off delay time relay KT2, start button S1
The time delay break contact of upper series connection power cut off delay time relay KT1 and power cut off delay time relay KT2 timing closing contact,
The auxiliary normally opened contact of the two ends parallel connection A.C. contactor KM of start button S1.
Wherein, the delay time of power cut off delay time relay KTI is disposed in contact with the maximum time t1 of device power-off, power-off
The delay time of time delay relay KT2 is set greater than the time t2 of t1.
The beneficial effects of the utility model are: simple in construction, easy to use, are effectively increased work efficiency so that exchange
After catalyst fault power-off again incoming call, it is possible to realize automatic Power resumption, it is not necessary to manually start, time saving and energy saving, simplify behaviour
Make formality, alleviate the labor intensity of operator.
Accompanying drawing explanation
Accompanying drawing 1 is circuit structure diagram of the present utility model.
Detailed description of the invention
In conjunction with accompanying drawing 1, the utility model will be further described:
This utility model includes 220V power supply, control circuit, insurance FU, start button S1, stop button S2, power cut off delay
Time relay KT1, power cut off delay time relay KT2,220V power supply is by insurance FU parallel connection A.C. contactor KM and power-off
Connect on time delay relay KT2, A.C. contactor KM and the power cut off delay time relay KT2 stop button S2 respectively, hands over
The two ends parallel connection power cut off delay time relay KT1 of stream catalyst KM, between described stop button S2 and A.C. contactor KM
Series control circuit, described control circuit includes when start button S1, A.C. contactor KM assist normally opened contact, power cut off delay
Between the time delay break contact of relay K T1 and the timing closing contact of power cut off delay time relay KT2, start button S1 is gone here and there
The time delay break contact of connection power cut off delay time relay KT1 and power cut off delay time relay KT2 timing closing contact, start
The auxiliary normally opened contact of the two ends parallel connection A.C. contactor KM of button S1.
Wherein, the delay time of power cut off delay time relay KTI is disposed in contact with the maximum time t1 of device power-off, power-off
The delay time of time delay relay KT2 is set greater than the time t2 of t1.
Operation principle:
Power cut off delay time relay KT1: power cut off delay time relay KT1 sets delay time as t1, presses startup
After button S1 A.C. contactor KM adhesive, A.C. contactor KM auxiliary normally opened contact is connected, power cut off delay time relay KT1 line
Circle is energized, and power cut off delay time relay KT1 time delay break contact moment closes, when the power break occurs, and A.C. contactor KM line
Circle dead electricity, A.C. contactor KM auxiliary normally opened contact disconnects, power cut off delay time relay KT1 coil blackout, and time delay starts, this
Time by power cut off delay time relay KT1 time delay break contact keep control loop connection, if power supply is extensive within the t1 time
Multiple normal, A.C. contactor KM coil automatic can obtain electric adhesive, and oil pumper recovers operating, as within the t1 time, power supply does not recovers,
Power cut off delay time relay KT1 time delay break contact disconnects, and manually presses after the power ups such as control circuit will be fully disconnected, need
Dynamic start button S1 adhesive A.C. contactor KM.
Power cut off delay time relay KT2: power cut off delay time relay KT2 sets delay time as t2, and t2 is more than t1,
After power cut off delay time relay KT1 is set as t1, when pressing stop button moment, when A.C. contactor KM, power cut off delay
Between relay K T1 coil blackout, A.C. contactor KM normally opened contact disconnect, power cut off delay time relay KT1 delayed contact closes
Closing, stop button normally opened contact closes, and power cut off delay time relay KT2 coil blackout, time delay starts, power-off after the t1 time
Time delay relay KT1 delayed contact disconnects, and after the t2 time, power cut off delay time relay KT2 timing closing contact is closed automatically
Close, A.C. contactor when so pressing stop button, can be disconnected immediately.
The above, be only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may profit
This utility model is revised by the technical scheme of above-mentioned elaboration or is revised as the technical scheme of equivalent.Therefore, foundation
Any simple modification that the technical solution of the utility model is carried out or substitute equivalents, belong to the greatest extent this utility model claimed
Scope.
