A power supply on both ends of a coil of the AC contactor can be converted into a direct current power supply when the AC contactor is started by installing the power saving device on both ends of the coil, so that the running voltage is low, the holding current is small, and the noise is small, thereby achieving objectives of energy conservation and noise elimination.
Description
Technical field
The utility model relates to a kind of battery saving arrangement of A.C. contactor, relates in particular to a kind of battery saving arrangement that is used for the A.C. contactor running.
Background technology
The A.C.power loss of present existing A.C. contactor is to be produced by the eddy current of the impedance of coil, iron core, magnetic hysteresis, leakage field; Noise is produced by alternating magnetic field; To burn be because coil, iron core are overheated, and the iron adhesive is bad, and short-circuited conducting sleeve damages or comes off and overheated causing; Therefore, cause A.C. contactor power consumption high, had potential safety hazard on the contrary.
Summary of the invention
The purpose of the utility model provides a kind of battery saving arrangement that is used for the A.C. contactor running with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises stop button switch, compound button switch, electric capacity, double throw rotary switch and diode; Said stop button switch is connected successively, and its two ends are connected with AC power behind normal open switch and the said A.C. contactor of said electric capacity, said A.C. contactor; Said electric capacity is connected in parallel with the two ends after the normal open switch of said A.C. contactor is connected and the normal open switch of said compound button switch; The end that said A.C. contactor connects said electric capacity is connected with the center link of said double throw rotary switch; Be connected with the negative pole of said diode again after the series connection of first link of said double throw rotary switch and the normally closed switch of said compound button switch; The positive pole of said diode is connected with an end of said AC power, and second link of said double throw rotary switch is connected with the end of said electric capacity near said stop button switch.
The said electric capacity of the utility model is the electric capacity of 4 ц/400V; Said diode is the diode of 1A/800V.
The beneficial effect of the utility model is:
After the coil two ends of A.C. contactor install the utility model additional;, A.C. contactor can the power supply at its coil two ends be become DC power supply after starting; Make and do not have phenomenons such as eddy current, magnetic hysteresis, leakage field in the A.C. contactor; So working voltage is low, it is little to keep electric current, noise is little, thereby reaches purpose energy-conservation, that eliminate the noise.
Description of drawings
Accompanying drawing 1 is the utility model circuit structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing: the utility model comprises stop button switch S B1, compound button switch S B2, capacitor C, double throw rotary switch SA and diode VD; Stop button switch S B1 successively behind normal open switch and the A.C. contactor KM of series capacitance C, A.C. contactor KM its two ends be connected with AC power; Capacitor C is connected in parallel with two ends after the normal open switch of A.C. contactor KM is connected and the normal open switch of compound button switch S B2; The end that A.C. contactor KM connects capacitor C is connected with the center link of double throw rotary switch SA; Be connected with the negative pole of diode VD again after the normally closed switch series connection of first link of double throw rotary switch SA and compound button switch S B2; The positive pole of diode VD is connected with an end of AC power, and second link of double throw rotary switch SA is connected with the end of capacitor C near stop button switch S B1.
Among the figure, capacitor C is the electric capacity of 4 ц/400V; Diode VD is the diode of 1A/800V.
Shown in accompanying drawing: but the circuit of the utility model is a kind of sinusoidal DC operation, and circuit of AC/DC of starting; Double throw rotary switch SA places " 1 " position when starting; Press start button switch S B2, its normally opened contact is closed, and normally-closed contact breaks off; At this moment A.C. contactor KM coil starts for simple alternating current through stopping push-button switch SB1 and start button switch S B2 energising.Often open the auxiliary contact closure for its two simultaneously, after unclamping start button switch S B2, its normally opened contact breaks off earlier, and closed behind the normally-closed contact, the KM coil is connected the alternating current 220V power supply through capacitor C, makes contactor keep adhesive.By the time after the start button switch S B2 normally-closed contact closure; Diode VD is often driven the auxiliary contact place in circuit through start button switch S B1, double throw rotary switch SA and A.C. contactor KM; At the positive half cycle of AC power, diode VD ends, and A.C. contactor KM coil is through the electric capacity energising; At the AC power negative half period, diode VD conducting, electric current is through capacitor C and diode VD formation path, makes that to flow through A.C. contactor KM coil current be direct current.
Shown in accompanying drawing: press stop button switch S B1, A.C. contactor KM coil blackout is discharged, cut off the control circuit power supply.
Because the electric current through coil when starting is a full-wave electric current, make contactor obtain enough starting currents and adhesive, when operation, the magnetic field of DC electromagnet is constant simultaneously, and adhesive is stable, does not have electric and magnetic oscillation, does not have phenomenons such as eddy current, magnetic hysteresis, leakage field.Before coil magnetic circuit was saturated, the suction-combining force was directly proportional with number of ampere turns, and coil impedance is little, and working voltage is low, and it is little to keep electric current, thereby reached purpose energy-conservation, that eliminate the noise.
