Abstract
The invention relates to an energy-saving alternating-current contactor, composed of a movable contact construction member, a static contact construction member, an electromagnetic coil and a base case. The energy-saving alternating-current contactor is characterized in that: the movable contact construction member comprises a permanent magnetic element; a thin soft magnet penetrates through a middle frame of the electromagnetic coil; and the two ends of the electromagnetic coil are provided with silicon controlled rectifiers. Accordingly, direction of a current passing through the electromagnetic coil can be controlled by controlling on-off of the silicon controlled rectifiers in a unit formed by connecting a front diode or a rear diode of the electromagnetic coil and the silicon controlled rectifiers in parallel, poles N and S of the soft magnet of the middle frame of the electromagnetic coil are controlled, thus the movable contact construction member containing the permanent magnetic element is pulled in or pushed off, the on-off state of the contactor is controlled, and the electromagnetic coil consumes no electricity when the contactor is pulled in. The silicon controlled rectifiers control the on-off of the electromagnetic coil, zero cross disconnection on the electromagnetic coil can be realized, the electromagnetic coil is prevented from producing back electromotive force, and the contactor acts more stably. Meanwhile, a permanent magnet is adopted for pulling-in, magnetic force is stronger, and power of the electromagnetic coil can be appropriately reduced, thus usage of copper wires and soft magnetic materials can be reduced. By adopting the energy-saving alternating-current contactor provided by the invention, energy is saved, the copper wires and soft magnetic materials are saved, and the action is stable.
Description
Affiliated technical field
The present invention relates to a kind of contactor, particularly a kind of energy saving ac contactor.
Background technology
At present, the power consumption of general A.C. contactor is bigger, and in service have an electromagnetic noise.Be to reduce energy consumption and noise, once carried out a large amount of research both at home and abroad, existing technology row can be divided into: keep current mode, 2. mechanical lock button-type, 3. micro electro mechanical snap close type, 4. permanent magnetism absorbent-type less 1..Wherein current mode is kept in minimizing will the support circuit more complicated, promotes relatively poor; The mechanical lock button-type has lost the basic function that the contactor outage discharges, and contains unsafe factor, and range of application is very limited; Micro electro mechanical snap close type is good than the former two, but complicated, promotes undesirable; Existing permanent magnetism adhesive type is more complicated and less stable substantially all, how not to promote substantially.
Summary of the invention
Bigger in order to overcome existing A.C. contactor power consumption, the shortcoming that electromagnetic noise is arranged in service the invention provides a kind of energy saving ac contactor, and its electricity consumption is few, does not have electromagnetic noise substantially.
The technical solution adopted for the present invention to solve the technical problems is: dynamic and static contact members, and solenoid, base shell is formed energy saving ac contactor.It is characterized in that: the moving contact member comprises permanent magnet component; The soft magnetism that passes the solenoid center is sparse; Perhaps there is the surface of individual direction greater than soft magnetism spare on the surface of permanent-magnet pieces contact position; All there is controllable silicon at solenoid two.Like this, silicon controlled conducting in the unit before or after the control solenoid after diode and the controllable silicon parallel connection, just the energy control flows is crossed the sense of current of solenoid, thereby N, the S utmost point of the soft magnetism of control solenoid center, also just can realize adhesive or push away the moving contact member that contains permanent magnet component, realize the on off operating mode of control contactor, and realize contactor not power consumption of solenoid when adhesive.By the break-make of SCR control solenoid, can also realize that the solenoid zero passage disconnects, avoid solenoid to produce inverse electromotive force, thereby reduce infringement other elements, make the contactor action more stable.Owing to adopt the permanent magnetism adhesive, magnetic force is stronger, can suitably reduce the power of solenoid simultaneously, therefore can reduce the consumption of copper cash and soft magnetic material.
The invention has the beneficial effects as follows: not power consumption of solenoid during adhesive, energy-conservation; Can save copper cash and soft magnetic material, and action is stable.

Among the figure, 1. normally closed interlock, 2. moving contact, 3. spring, 4. solenoid, 5. permanent-magnet pieces, 6. soft magnetism spare, 7. normally open contact, 8. base shell, 9. control circuit, 10. diode 1,11. controllable silicon 1,12. photosensitive tube 1,13. photosensitive tube 2,14. controllable silicons 2,15. diodes 2,16, piezo-resistance.
Embodiment
Among Fig. 1, Fig. 2, energy saving ac contactor is by dynamic and static contact members, solenoid, and base shell is formed.Wherein the fixed contact member comprises normally closed interlock (1), normally open contact (7); The moving contact member comprises moving contact (2) and permanent-magnet pieces (5); Solenoid (4) and soft magnetism spare (6) are formed electromagnetic circuit; Push away the moving contact member, must there be the surface of individual direction greater than soft magnetism spare (6) on the surface of permanent-magnet pieces during adhesive (5) contact position, and perhaps the surface, contact position of soft magnetism spare (6) is sparse.Adopted permanent magnetic material simultaneously, the magnetic force that electromagnetic circuit produces can the little of more common contactor can both be effective, thereby can save copper cash and soft magnetic material.And adopting permanent-magnet pieces (5) adhesive soft magnetism spare (6), solenoid after the adhesive (4) need not be switched on and all can be kept, and has saved electric energy.And the adhesive of contactor or push away by the decision of the sense of current of solenoid.If the magnetic field adhesive moving contact member that control controllable silicon 1 (11) conducting solenoid (4) produces, then the magnetic field of controllable silicon 2 (14) conducting solenoids (4) generation will push away the moving contact member.Rayed photosensitive tube 1 (12) just can trigger controllable silicon 1 (11), allows electric current pass through diode 2 (15), solenoid (4), controllable silicon 1 (11), thereby the magnetic field adhesive moving contact member that solenoid (4) is produced is connected normally open contact (7) two ends.Rayed photosensitive tube 2 (13) just can trigger controllable silicon 2 (14), allows electric current pass through diode 1 (10), solenoid (4), controllable silicon 2 (14), thereby the magnetic field that solenoid (4) is produced pushes away the moving contact member, and normally closed interlock (1) two ends are connected.Be characterized in: diode 2 (15) and controllable silicon 2 (14) compose in parallel ballast unit series electrical magnetic coil (4) unit that composes in parallel of order serial connection controllable silicon 1 (11) and diode 1 (10) again.Easily control flows is crossed the sense of current of solenoid (4).Wherein control circuit can be arranged to interlocking with the drive circuit of two photosensitive tubes of irradiation, just can easily control the adhesive of A.C. contactor or pushes away.Because not having reverse Control current, controllable silicon is that zero passage disconnects certainly, so solenoid (4) can not produce inverse electromotive force as the solenoid of common contactor, other elements is exerted an influence; Make the contactor action more stable.Vibrations for fear of the moving contact member simultaneously make solenoid (4) generation induced electromotive force exert an influence to other elements, the piezo-resistance (16) in parallel at solenoid (4) two ends.
In addition, because controllable silicon can adopt photosensitive tube or optocoupler control, make this kind contactor can cooperate the numeric type output interface of various automatic controls easily.
