Embodiment

Below in conjunction with accompanying drawing, the utility model execution mode is described further:

as shown in Figure 1, the utility model provides a kind of self-sustaining energy-saving electromagnet, include yoke 1 and be placed in yoke 1 interior coil rack 2 and solenoid 3, be provided with moving iron core 4, static iron core 5 and permanent magnet 6 in coil rack 2, moving iron core 4 one ends are placed in outside yoke 1, and the other end can fit or separate with static iron core 5 under the magnetic force of solenoid 3, need long-term energising in order to solve existing electromagnet solenoid 3 when controlling Intelligent electronic-type ammeter contact break-make, cause the technical problems such as energy waste and the lost of life, described solenoid 3 includes and is wrapped in coil rack 2 outer closing coil 31 and separate winding 32, closure, separate winding 31,32 same pole to an end adjacently be arranged on coil rack 2 centres and closure, separate winding 31,32 inlet wire phase and connect, with the inlet wire of closing coil 31 and separate winding 32 and connect, in use, only need to connect closure, separate winding 31,32 outlet, make electric current just can realize closure or the separation of electromagnet through closing coil 31 or separate winding 32, the end of described moving iron core 4 in coil rack 2 be placed in below closing coil 31 and and static iron core 5 between be provided with cut spring 7, the magnetic force of closing coil 31 can order about moving iron core 4 and fit with static iron core 5 end faces to static iron core 5 one side displacements and under the magneticaction of permanent magnet 6 and form the first service position of closed-lock, is separated with static iron core 5 with the moving iron core 4 of the magnetic drive of separate winding 32 and forms under the elastic force effect of cut spring 7 to separate locking the second service position, solenoid 3 is made as two, and between moving iron core 4 and static iron core 5, cut spring 7 is set, when the needs electromagnet is closed, the outlet of connecting closing coil 31 makes electric current pass through closing coil 31 through inlet wire, closing coil 31 namely generates an electromagnetic field and the elastic force that overcomes cut spring 7 orders about moving iron core 4 to static iron core 5 one side horizontal slidings, after moving iron core 4 and static iron core 5 are fitted, just can be connected with static iron core 5 adhesives under the magneticaction of permanent magnet 6, form the self-sustaining Operating In Persistent Current Mode state of electromagnet, at this moment, closing coil 31 outages, energy-conservation purpose when realizing Operating In Persistent Current Mode, and when the needs electromagnet separates, the outlet of connecting separate winding 32 makes electric current pass through separate winding 32 through inlet wire, separate winding 32 can produce equally with the electromagnetic field of closing coil 31 adverse effect power and the magnetic force that overcomes permanent magnet 6 iron core 4 and static iron core 5 are separated, and realize moving iron core 4 and static iron core 5 under the elastic force effect of cut spring 7 separate the self-sustaining operating state, at this moment, separate winding 32 outages, thereby the energy-conservation purpose when realizing the electromagnet disconnection, adopt this structure, when electromagnet is in separation or closure state, closed, separate winding 31,32 all can need not long-term energising and just can realize the self-sustaining operating state, only need to be when switching the operating state of electromagnet, closing coil 31 or separate winding 32 are carried out the moment energising to be got final product, so not only can effectively save the energy, lower use cost, extend the useful life of electromagnet, simultaneously, as long as connect closure, separate winding 31,32 outlet just can realize the switching of work of electromagnet state fast, greatly facilitates long-range or automatic control.
