Description
The utility model relates to A.C. contactor DC operation energy saver, belongs to electricity field.
The A.C. contactor DC operation is a kind of energy-saving run mode that adopts at present, and the key problem of this operational mode is that high voltage startup, low pressure keep.Generally adopt at present the auxiliary contact of A.C. contactor self to carry out conversion between the high-low pressure.Because owing to cooperate not good auxiliary contact disjunction too early, can cause the chatter of main contact in auxiliary contact out-of-shape of himself and the attracting process, serious meeting causes the damage of A.C. contactor main contact.In addition, utilize himself auxiliary contact to also have the wiring complexity, be difficult for the shortcoming of installing.
The purpose of this utility model is to provide a kind of A.C. contactor DC operation energy saver.
The purpose of this utility model is achieved through the following technical solutions: a kind of A.C. contactor DC operation energy saver, comprise that the solenoid L of A.C. contactor goes up the rectification circuit that connects, and the two ends of solenoid L also are connected to sustained diode
6, in the interchange input of rectification circuit, be serially connected with a decompression capacitor C
2, at decompression capacitor C
2On be parallel with the normally closed interlock ZJ of intermediate relay ZJ

3Be connected in the output of another rectification circuit the interchange input of this another rectification circuit and decompression capacitor C after the parallel connection
1Be attempted by decompression capacitor C after the serial connection
2On the ac main circuit in front.
It is by diode D that described solenoid L goes up the rectification circuit that connects
5The half-wave rectifying circuit of Gou Chenging alone.
Another rectification circuit that connects on the described intermediate relay ZJ is by four diode D
1, D
2, D

Because the utility model is at decompression capacitor C
2On be parallel with the normally closed interlock ZJ of an intermediate relay ZJ
1, and on the coil of this auxiliary relay and be connected to a capacitor C
3, thereby when the solenoid of A.C. contactor when receiving the adhesive instruction, can be earlier by normally closed interlock ZJ
1, the total head adhesive starts, and the voltage on the coil of intermediate relay ZJ just can be raised to operating voltage thereafter, intermediate relay ZJ time-delay adhesive, its contact ZJ
1The time-delay disjunction, the DC operation solenoid L of A.C. contactor is then by decompression capacitor C
2Low pressure operation after the dividing potential drop plays energy-conserving action.As can be seen, the action of intermediate relay ZJ lags behind a bit of time than the action of A.C. contactor all the time, has guaranteed the accurate work of A.C. contactor.In addition, energy saver circuit of the present utility model is simple, has a style of one's own, and only needs during use to get final product on the corresponding coil that be connected A.C. contactor, not only made things convenient for and used and keep in repair, also be convenient to the existing A.C. contactor that is just using in system is carried out reducing energy consumption.As seen, this energy-conservation device has a wide range of applications.
Below in conjunction with accompanying drawing the utility model is made further explanation:
Fig. 1 is circuit theory diagrams of the present utility model.
Among Fig. 1, the utility model major loop constitutes the decompression capacitor C of A.C. contactor DC operation solenoid L major loop by being cascaded
2With halfwave rectifier diode D
5, and the sustained diode that is connected in parallel on solenoid L two ends
6It is main formation.The main points of control are at decompression capacitor C
2On be parallel with the contact ZJ commonly used of an intermediate relay ZJ
