Description
Technical field
The present invention relates to a kind of A.C. contactor, especially a kind of electromagnetic energy-saving noise elimination A.C. contactor.
Background technology
At present, the electromagnetic system of A.C. contactor still needs to continue to solenoid after adhesive, the normal work of guarantee A.C. contactor, and this A.C. contactor is due to the lasting energising of needs, so electromagnetic system temperature is high, first cause the useful life of contactor short; Meanwhile, in the energized state, current noise is also very high for the solenoid of A.C. contactor, and noise pollution is serious, poor working environment.3rd, the solenoid of A.C. contactor continues energising, also wastes a large amount of electric energy, if be all added by the electric energy that the contactor of all for whole nation power consumption equipments is wasted, should be equivalent to an energy that big power station generates electricity.Therefore, designing a kind of electromagnetic energy-saving noise elimination A.C. contactor, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of electromagnetic energy-saving noise elimination A.C. contactor.
The technical scheme that the present invention solves its technical problem is:
A kind of electromagnetic energy-saving noise elimination A.C. contactor, primarily of electromagnetic system, main contacts system, auxiliary contact system, base forms, base between electromagnetic system and main contacts system is fixed with the rectangle bent axle frame of front apron with " U " v notch v, bent axle frame is provided with bent axle, the connecting rod neck of bent axle is hinged with " L " shape connecting rod, the other end of " L " shape connecting rod and the moving magnet backplate of electromagnetic system hinged, distance between the axis of the axis of the connecting rod neck of bent axle and the trunnion of bent axle equals 1/2 of displacement, the height of " U " v notch v of bent axle frame can >=oscillating quantity of " L " shape connecting rod, the base of contact system side is also fixed with solenoid actuator, the sidewall of bent axle frame main contacts system side has solenoid actuator magnetic post passing hole, solenoid actuator magnetic post passing hole is at the rear portion of the trunnion of bent axle, the upper change point of solenoid actuator magnetic post is a little less than the lower-limit point of the trunnion of bent axle.
The technical scheme that the present invention solves its technical problem can also be:
The leading section of solenoid actuator magnetic post of the present invention is taper type.
The present invention is provided with normally closed sensitive switch on the backboard of bent axle frame, makes sensitive switch just in time back down normally closed sensitive switch, make normally closed sensitive switch be in off-state after the connecting rod neck of bent axle reaches during dead point.
Operation principle of the present invention is:
When pressing start button QA, contactor coil and solenoid actuator coil simultaneously electric, contactor adhesive, solenoid actuator magnetic post is overhanging, and moving magnet backplate drives crank rotation by " L " shape connecting rod, dead point or only slight beyond rear dead point after the connecting rod neck of bent axle reaches, the connecting rod neck of bent axle makes normally closed sensitive switch disconnect, and contactor coil dead electricity, due to the stop of solenoid actuator magnetic post, electromagnetic system keeps running without electricity under contactor coil power failure state, and main contacts system is connected; When pressing TA, solenoid actuator magnetic post bounces back, and under moving magnet spring action, main contacts system disconnects.
This kind of structural principle is same with control method is suitable for vertical alternating-current contactor.
Compared with prior art, the present invention is energy-conservation, noiseless, long service life.
Accompanying drawing explanation
Fig. 1 is the front view of this practical structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is using state control circuit schematic diagram of the present invention.
