Description

A kind of pair of monostable permanent magnet AC contactor
Technical field
The utility model relates to the low-voltage distribution apparatus technical field, especially relates to a kind of pair of monostable permanent magnet AC contactor.
Background technology
A.C. contactor is the automation control apparatus that is used for switching on or off the main circuit that has load or big volume controlled circuit, and versatility is very strong.Be widely used in controlling motor, capacitor, illuminating line, resistance furnace and other power consumption equipment.The developing history of A.C. contactor is very long, and structural shape is also a lot, but the contact of most of A.C. contactors is to keep by sucking coil; The mechanical interlocking in addition, self-locking mechanism, the mechanical breakdown that have are many, consume certain electric energy again.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of pair of monostable permanent magnet AC contactor, reaches the electromagnetism actuating function of the DC pulse control permanent magnetism snap close of alternating current operation, not only economize on electricity, and the serviceability of raising contactor.
For achieving the above object, the utility model by the following technical solutions:
A kind of pair of monostable permanent magnet AC contactor of the present utility model comprises control circuit and electromagnetic operating mechanism; Described electromagnetic operating mechanism comprises closing coil, switching winding, electromagnet armature, transmission body, the moving joint of bridge-type, board-like Locking device, wherein, switching winding and closing coil integral type are provided with, and switching winding, closing coil, the permanent magnet and the fixed contact that are fixed on the Locking device are stationary part; Magnetic inductive block on electromagnet armature, transmission body, the moving joint of bridge-type and the board-like Locking device is a moving part; Control circuit comprises combined floodgate electric contact, separating brake electric contact, AC/DC convertor, the ac input end of AC/DC convertor is connected AC power by the combined floodgate electric contact with the separating brake electric contact respectively, and the dc output end of AC/DC convertor is connected with switching winding with described closing coil respectively.
Further, also comprise a no-voltage relay and a step-down energy storage type AC/DC convertor, the dc output end of this step-down energy storage type AC/DC convertor connects a normal opened contact of diode, described no-voltage relay successively, connects described switching winding then.
The beneficial effects of the utility model are: compared with prior art, because employing is integrated, simple in structure, mechanical breakdown is few; Because adopt the actuating of ac-dc conversion DC pulse, non-actuating state coil is not charged, saves energy, and do not have common A.C. contactor contact and iron core vibration problems; Because adopt the bistable state snap close, contactor is reliable and stable, the contact of contactor contact is good, has significantly reduced to burn out the contact fault; Because adopt electric energy storage type AC/DC convertor monostable to reply snap close, after the power supply decompression, contactor fixedly returns in the contactor off-state; Simultaneously, this type contactor also can combine with various protective circuits such as breaking protection, earth leakage protective, over-current over-voltage protection and control loop easily and constitute intelligent electric appliance.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Fig. 1 is the electromagnetic operating mechanism structural representation of the utility model contactor;
Fig. 2 is the control circuit figure of the utility model contactor.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Standing part as shown in Figure 1 is made up of fixed permanent magnet 7a and 7b, the fixed contact 6 of the integrated closing coil 1 of electromagnet, switching winding 2, Locking device; The integrated motion rigid body that moving part is made up of the magnetic inductive block 8 on electromagnet armature 3, transmission body 4, the moving joint 5 of bridge-type and the board-like Locking device.
As shown in Figure 2, be 220v between A and the N terminal, the electric control circuit of the utility model contactor is the combined floodgate circuit that is made of jointly the AC/DC convertor 10 of combined floodgate electric contact 9 controls and closing coil 1.The separating brake circuit that constitutes jointly by the AC/DC convertor 10 of separating brake electric contact 11 control and switching winding 2.Be connected to through the contact J of diode and no-voltage relay 13 again by step-down energy storage type AC/DC convertor 12 and constitute the decompression monostable on the switching winding 2 and reply snap close.As shown in Figure 2, what should illustrate also has: if need install earth leakage protective, overvoltage protection, overcurrent protection, breaking protection etc. additional the time, their output signal and be connected to relay J and get final product, also can combine the formation intelligent electric appliance with other control circuits.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
