The contactor provided by the utility model has the advantages of low power consumption and low cost.
Description
Technical field
The utility model relates to a kind of contactor, particularly a kind of energy-saving type contactor.
Background technology
Contactor is the important power control member for control motor start-stop and other electrical load break-make.The adhesive of tradition contactor mainly is abutted against the tentaculum coil and is realized by electric current for a long time, and the capacity of contactor is larger, and the electric current that needs is just larger; Longer pickup time such as contactor, the electric energy of consumption is also just more.
Contactor is electrified and automation and other economic construction field extensive use in industrial or agricultural, and its consumption is large, longevity of service.And along with popularization electrified, automatic technology, the consumption of contactor increases very fast.Therefore, reduce the active demand that contactor cost and less electrical energy consumption are undoubtedly market.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of new type contactor, has little power consumption, advantage that cost is low.
Contactor described in the utility model comprises:
Electromagnet and moving iron core, described electromagnet comprises static iron core and coil, described moving iron core links to each other with a spring and links to realize adhesive and the release of contactor with the contact system of contactor, wherein said moving iron core is permanent magnet, and described contactor comprises that also a control circuit is to control the electric current in the described coil.
By the setting of electromagnet and permanent magnet, described electromagnet in coil during by forward current and described permanent magnet attract each other to realize the adhesive of contactor.
By the setting of control circuit, no current in the described coil when the contactor adhesive.
Further, by the setting of electromagnet and permanent magnet, described electromagnet in coil during by reverse current and described permanent magnet mutually repel to realize the release of contactor.
According to the utility model, the adhesive of contactor need to not alived in coil always.When no current in the solenoid after the adhesive passes through, still can keep in touch by the attraction of permanent magnet and static iron core the adhesive of device.Thus, realized the reduction of power consumption by the simple structure of described contactor.
Description of drawings
Fig. 1 shows the structural representation of contactor described in the utility model.
Embodiment
Describe contactor of the present utility model in detail below in conjunction with accompanying drawing 1.
Contactor described in the utility model is that from the main distinction of traditional contactor the core structure of solenoid is different with the mode that drives solenoid.As shown in Figure 1, contactor comprises electromagnet 1 and moving iron core 2, and described electromagnet comprises static iron core 11 and coil 12, and described moving iron core 2 links to each other with a spring 4 and links to realize adhesive and the release of contactor with the contact system of contactor.Wherein, moving iron core 2 is permanent magnet, and described contactor comprises that also a control circuit 3 is to control having or not and direction of electric current in the described coil.
Preferably, static iron core 11 is to be made by the monoblock ferromagnetic material, rather than coincides with silicon steel sheet such as the traditional electrical pole core and to make, and structure is more simple.
The basic functional principle of contactor described in the utility model is as follows:
When the adhesive of needs contactor, under the control of control circuit 3, solenoid 12 logical forward currents, the mutual adhesive in magnetic field that electric current produces in static iron core 11 in the magnetic field of permanent magnet 2 and the coil, the elastic force that overcomes back-moving spring 4 makes the contact of contactor by adhesive.
After the adhesive, just pass through without drive current in the solenoid.The adhesive of contact can be kept by permanent magnet 2 and attracting each other of static iron core.
Further, when the needs contactor resets disconnection, under the control of control circuit 3, solenoid 12 same reverse currents, repel mutually with the magnetic field of permanent magnet 2 in the magnetic field that electric current produces in static iron core 11 in the solenoid 12 (opposite when its polarity and adhesive), and superimposed with the elastic force of back-moving spring 4, so that the contact of contactor resets (traditional contactor only resets by the elastic force of back-moving spring).
Contactor described in the utility model has following characteristics:
1, economize on electricity, power factor height
According to contactor of the present utility model, only just there be electric current to pass through by extremely lacking in the process of adhesive in the solenoid at electromagnet, and only have control circuit to consume small electric energy at the state (overwhelming majority time is in this kind state in the contactor work) of adhesive, so electric energy is high.A coil rating voltage is AC220V, the contactor model machine of major loop rated current 100A, the attracting state power consumption only 0.59W (and the A.C. contactor of traditional same specification in the attracting state power consumption about more than 20 watts also has the reactive power more much bigger than this numerical value in addition; Power in startup moment of adhesive is just more much bigger, with manufacturer's difference difference to some extent).Because the electric current by solenoid is direct current, thus the electric current in the startup moment solenoid of adhesive and little, with identical in the course of action.
2, adhesive and rate of release are fast
Through testing at the model machine of above-mentioned specification, only more than 30 millisecond of its pickup time, release time is then ofer short duration many.Alleviate the ablation degree of contact, prolonged the useful life of contact.And contact is the principal element that determines the contactor life-span useful life, thereby has prolonged the life-span of contactor.The attracting state of contactor is to be kept by the suction-combining force of permanent magnet to static iron core, compares with traditional contactor, is not subjected to the impact of mains fluctuations, also is beneficial to the life-span that prolongs contactor.Improved rate of release, can reduce and the electric arc that produces when avoiding cutting off the power supply causes the work safety accidents such as phase fault.
3, under-voltage protection function is arranged
According to control circuit described in the utility model, contactor just automatically resets breaking-off contact not to load supplying when line voltage is lower than the minimum of requirement, has avoided burning because electric current increases owing to brownout causes some load (such as motor).This can't realize at traditional electromagnetic contactor.
4, this contactor is silent at the sticking state, without the annoying interchange boom of A.C. contactor.
5, easy to use.Power supply and contactor and startup, stop knob etc. be connected and traditional contactor identical.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
