The utility model has the advantages that the structure is simple, the operation is convenient, the armature iron can directly operate a main shaft of a movable switch, a transmission link does not exist, the permanent magnet is fixed on a machine frame, the impact and the vibration are small, the mechanical latch is not required, the clamping does not exist, the fault operation does not exist, and the maintenance-free operation of the vacuum switch can be realized.
Description
The utility model relates to a kind of bistable state permanent magnet operating mechanism of vacuum switch.
General high-pressure vacuum switch all have one make its main axis rotation drive contact carry out closure (combined floodgates) or open (separating brake) also can keep close, the operating mechanism of gate-dividing state.This mechanism often is made up of the complicated mechanical system.The Chinese patent 89106683.7 comparatively approaching with the utility model discloses a kind of bistable magnetic actuator.This mechanism is by yoke, two separating brake iron cores, and two switching windings, permanent magnets etc. are formed.It is clipped in permanent magnet between two moving iron cores, and the servo-actuated iron core moves up and down together.Permanent magnet will bear bigger impact and vibrations during this structure operation, will produce adverse influence to its service behaviour; Moving quality unshakable in one's determination is bigger, and motional inertia is big, directly influences the mechanical property of switch.
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of transmission link simple in structure, no is provided, is hit and shakes little, do not have mechanical snap close, wearing and tearing are little, can realize the bistable state permanent magnet operating mechanism of on-pole switch of the non-maintaining operation of vacuum switch.
Main solution of the present utility model is achieved in that it mainly adopts switching winding 3, closing coil 8 is installed in respectively on the separating brake unshakable in one's determination 2 and the iron core 9 that closes a floodgate, and be fixed on the yoke 1, magnetic conductor 7 connects permanent magnet 10 and is fixed on the yoke 1, fixing rotation magnetic conductor 5 on the magnetic conductor 7, armature 4 is installed on the rotation magnetic conductor 5 is fixed on the axle 6, by bearing fixing on frame.
Description of drawings:
Fig. 1 is the utility model structural representation:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
Above-mentioned accompanying drawing is the schematic diagram that the utility model is in closing position.
The utility model employing switching winding 3,, closing coil 8 is installed in respectively on the separating brake unshakable in one's determination 2 and the iron core 9 that closes a floodgate, and be fixed on the yoke 1, magnetic conductor 7 connects permanent magnet 10 and also is fixed on the yoke 1, fixing rotation magnetic conductor 5 on the magnetic conductor 7, armature 4 is installed on the rotation magnetic conductor 5 is fixed on the axle 6, by bearing fixing on frame.The radial polarization magnetic flux flow that permanent magnet 10 produces is crossed two magnetic loops; One is the closed combined floodgate magnetic circuit of low magnetic resistance that is made of permanent magnet 10, fixed magnetizer 7, rotation magnetic conductor 5, armature 4, the iron core 9 that closes a floodgate, yoke 1, another is by permanent magnet 10, magnetic conductor 7, rotation magnetic conductor 5, armature 4, air gap delta, the non-closed separating brake magnetic circuit of high magnetic resistance that separating brake iron core 2, yoke 1 constitute.Owing to there is air gap delta, the magnetic resistance of separating brake magnetic circuit is high, and mainly the flow through combined floodgate magnetic circuit of low magnetic resistance of polar flux, armature 4, and can not inhaled by the pole shoe of separating brake iron core 2 on unshakable in one's determination 9 the pole shoe of closing a floodgate by firm suction.
When switching winding 3 energisings, in the separating brake magnetic circuit, produce a short-term operation magnetic flux, this flow direction direction with polar flux in magnetic conductor (5,7) is consistent, thereby can not produce demagnetizing effect to permanent magnet.The short-term operation magnetic flux increases the magnetic flux in the air gap delta, and the magnetic flux in the iron core 9 that closes a floodgate is reduced.The armature 4 that former cause polar flux is kept will be by broken ring with the stable state of 9 stickings unshakable in one's determination that close a floodgate, armature drives switch spindle and is rotated counterclockwise, make the pole shoe sticking of armature 4 and separating brake iron core 2, switching winding 3 outages, the polar flux that is produced by permanent magnet 10 is kept the closed sticking state of separating brake magnetic circuit, and vacuum is opened sky and is stabilized in gate-dividing state.
When closing coil 8 energisings, can make armature 4 drive switch spindle 6 dextrorotations equally and go to closing position, and keep the "on" position of vacuum switch constant by polar flux.Alternately closed, the switching winding energising, said process can not have repeating down of placing restrictions on.The switch that the utility model is mixed is the pole vacuum on-load switch.
Compared with the prior art the utility model has the following advantages: 1, simple in structure, easy to use; 2, the direct actuating switch spindle of armature, no transmission link; 3, permanent magnet is fixed on the frame, is rushed Hit and shake little; 4, machinery-free snap close, it is little to wear and tear, clamping stagnation not, no malfunction can realize that vacuum opens The non-maintaining operation of closing.
