Solving the technical solution of above-mentioned technical problem is：
A kind of breaker, it includes Insulating frame, vacuum switch tube, permanent magnet mechanism, is fixed respectively in Insulating frame both sides
There is vacuum switch tube, permanent magnet mechanism is fixed among two vacuum switch tubes, two vacuum switch tubes and permanent magnet mechanism are same
Plane is installed side by side, and permanent magnet mechanism is fixed among Insulating frame, and the static side of two vacuum switch tubes is connect with upper busbar respectively,
It being separately fixed on Insulating frame again, the moved end of two vacuum switch tubes is made of conductive strips, touch spring and adjustment bolt, and
It is connected respectively with insulation actuating arm.
Above-mentioned breaker, the permanent magnet mechanism are made of closing coil, dynamic iron core, permanent magnet, switching winding, closing coil
It is sleeved on dynamic iron core top, switching winding is sleeved on dynamic iron core lower part, and permanent magnet is housed among closing coil and switching winding, dynamic
The top and bottom of iron core are respectively provided with top guide bar, lower guide rod, and top guide bar is connected with dynamic iron core, lower guide rod and dynamic iron core and exhausted
Edge actuating arm centre position is connected.
The utility model has the beneficial effects that：
Two vacuum switch tubes and permanent magnet mechanism of the utility model are installed side by side in same plane, two vacuum switch tubes
It keeps symmetrical in the corresponding position of both sides, realizes volume minimization and linear drives, while permanent magnet mechanism is designed to both sides
With a degree of stray field, making both sides vacuum switch tube, charged particle is attracted or is arranged in electric arc between contact in disjunction
Reprimand, to make electric arc elongate, plays the role of magnetic blow-out, electric arc is made to be more easy to extinguish.
The utility model has the advantages of simple structure, dependable performance, cheap, and interrupting performance higher, the scope of application are wider, can make
It is widely used in AC and DC electric system for breaker and contactor.Multipole open circuit can be become after the utility model combination
Vacuum switch tube series connection can be used as high voltage, the dc circuit breaker of high current or contactor and uses by device or contactor.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Figure label is as follows：Top guide bar 1, closing coil 2, dynamic iron core 3, permanent magnet 4, permanent magnet mechanism 5, switching winding 6, under
Guide rod 7, touch spring 8, insulation actuating arm 9, adjustment bolt 10, upper busbar 11, Insulating frame 12, vacuum switch tube 13, arc
Plate 14, conductive strips 15.
Specific implementation mode
The utility model is by Insulating frame 12, vacuum switch tube 13, permanent magnet mechanism 5, upper busbar 11, top guide bar 1, lower guide rod
7 compositions.
It is shown in figure, vacuum switch tube 13 is respectively fixed in 12 both sides of Insulating frame, in two vacuum switch tubes 13
Between fix permanent magnet mechanism 5, two vacuum switch tubes 13 and permanent magnet mechanism 5 are installed side by side in same plane, permanent magnet mechanism 5 fix
Among Insulating frame 12.
The quantity of vacuum switch tube 13 can be with more than two, two or more vacuum switch tubes 13 and permanent magnet mechanism
5 is arranged side by side in same plane, and is symmetrically fixed on 5 both sides of permanent magnet mechanism.
It is shown in figure, the static side of two vacuum switch tubes 13 is connect with upper busbar 11 respectively, then is separately fixed at insulation frame
On frame 12, the moved end of two vacuum switch tubes 13 is made of conductive strips 15, touch spring 6 and adjustment bolt 10, and respectively with absolutely
Edge actuating arm 9 is connected, and adjustment bolt 10 can be opened away from the adjustment of the, excess of stroke.
It is shown in figure, permanent magnet mechanism 5 is made of closing coil 2, dynamic iron core 3, permanent magnet 4, switching winding 6.Closing coil 2
It is sleeved on 3 top of dynamic iron core, switching winding 6 is sleeved on 3 lower part of dynamic iron core, and permanent magnet is housed among closing coil 2 and switching winding 6
4, it is respectively provided with top guide bar 1, lower guide rod 7, lower guide rod 7 and insulation 9 centre position phase of actuating arm in the top and bottom of dynamic iron core 3
Connection.
When the utility model is used, when dynamic iron core 3 moves upwards, the insulation actuating arm 9 that is connected with lower guide rod 7 simultaneously to
Upper movement makes vacuum switch tube 13 close a floodgate to drive two 13 moving contacts of vacuum switch tube to move upwards；Conversely, dynamic iron core 3
When moving downward, 13 separating brake of vacuum switch tube.And so on operation realizes the combined floodgate and separating brake of breaker or contactor.
Since vacuum switch tube 13 keeps symmetrical in the corresponding position of 5 both sides of permanent magnet mechanism, to ensure the two poles of the earth vacuum switch
The synchronization splitting or integrating lock of pipe 13, and realize linear drives with vacuum switch tube 13, volume minimization, straight line are realized with this
Driving, while permanent magnet mechanism 5 is designed to that both sides have a degree of stray field, make both sides vacuum switch tube 13 in disjunction
Charged particle is attracted or is repelled in electric arc between contact, to make electric arc elongate, plays the role of magnetic blow-out, and electric arc is made to be more easy to put out
It goes out, to keep breaker breaking capacity stronger.
