The switching winding and the closing coil are successively set on the separating brake and kept on the downside of magnet, and the top of the eddy-current disc is with going out
The moving contact linkage of arc chamber, the storage capacitor connects the switching winding and the closing line by controllable silicon energy supply
Circle, the control end of the controllable silicon is provided with controller.
Further, the surface of the switching winding and the closing coil is all wound with copper lenticular wire.
Further, institute's storage capacitor is Large Copacity thin-film capacitor.
Relative to prior art, Fast Speed Vacuum Circuit Breaker described in the utility model has the advantage that：
The Fast Speed Vacuum Circuit Breaker that the utility model is provided, the storage capacitor being made of Large Copacity thin-film capacitor is as confession
Power supply, using controllable silicon as trigger, closes a floodgate and keeps magnet and separating brake to keep magnet as permanent magnet mechanism, by vacuum switch
Actuation time is reduced within 8ms, and speed substantially accelerates.The actuation time of the breaker accelerated, shorten non-faulting region
Power off time；The reclosing number of times of breaker is reduced, the service life of breaker is added.And failure occur with
It can play a part of reducing fault impact on family side and main line.
If the 1, failure is in user side, user demarcation circuit breaker failure completes Fault Isolation, non-faulting region in 10ms actions
Do not have a power failure, reduce the influence to other users.
If the 2, failure is on main line, separating brake action joins by dump before main line trouble point in section switch 10ms
Network breaker is closed a floodgate in 30ms, and power supply is supplied into non-faulting user.

Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, the utility model provides a kind of Fast Speed Vacuum Circuit Breaker, including eddy-current disc 1, close a floodgate keep magnet 2,
Separating brake keeps magnet 3, switching winding 4, closing coil 5, controllable silicon 6 and storage capacitor 7, and the eddy-current disc 1 is arranged on the conjunction
Lock is kept between magnet 2 and separating brake holding magnet 3, and the switching winding 4 and the closing coil 5 are successively set on described
Separating brake keeps the downside of magnet 3, and the top of the eddy-current disc 1 is linked with the moving contact 9 of arc-chutes 8, and the storage capacitor 7 passes through institute
The energy supply connection switching winding 4 of controllable silicon 6 and closing coil 5 are stated, the control end of the controllable silicon 6 is provided with controller 11.
The surface of the switching winding 4 and the closing coil 5 is all wound with copper lenticular wire.
Institute's storage capacitor 7 is Large Copacity thin-film capacitor.
The course of work of this example：Eddy-current disc 1 replaces moving magnet, and the quick action of eddy-current disc 1 is more stablized.In division
Moved up and down during lock, drive the moving contact 9 in arc-chutes 8 to complete divide-shut brake action.
Switching winding 4 and closing coil 5 are wound using special copper lenticular wire, increase the electric current passed through, are produced stronger
Magnetic field, increases the active force of divide-shut brake, accelerates eddy-current disc 1 and moves up and down speed.
Controllable silicon 6 replaces relay, and the actuation time of controllable silicon 6 is Microsecond grade, instead of actuation time for Millisecond after
Electrical equipment.Reduce the response time that control loop sends operation circuit after actuating signal.
Storage capacitor 7 uses vast capacity thin-film capacitor, the electric current provided during action as operation power, storage capacitor 7
Much larger than the electric current of the offer of conventional capacitive.
When the moving contact 9 and static contact 10 of arc-chutes 8 are in open position, eddy-current disc 1 is in top, and eddy-current disc 1 is with closing
Gap is larger between lock keeps the gap of magnet 2 smaller, also smaller with respect to magnetic resistance, and eddy-current disc 1 and separating brake keep magnet 3, relatively
The magnetic resistance answered is also larger, therefore the magnetic line of force formed of permanent magnet is largely focused on top, so as to produce very big upward suction
Gravitation, by the absorption of eddy-current disc 1 tightly above,
When breaker will close a floodgate, controllable silicon 6 is controlled by controller 11, closing coil 5 produces sensing by switching current
Magnetic field, the magnetic field produces downward attraction to vortex, 1, with the increase of switching current, and the downward attraction is become by lower
Greatly, when switching current reaches a certain critical value, the resultant direction that eddy-current disc 1 is subject to downwards, starts to move downward.
When eddy-current disc 1 reaches bottom, combined floodgate keeps the magnetic field that both magnet 2 and closing coil 5 are produced by the jail of eddy-current disc 1
The absorption in jail is in bottom.Switching current is disappeared, and eddy-current disc is kept lower lower portion by the magnetic field for keeping magnet 2 to produce of now closing a floodgate
Put.So far, breaker completes closing operation.
Similarly switching winding 4 it is electric after, eddy-current disc 1 upwards move, by separating brake keep magnet 3 maintain it in sub-gate position
Put.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
