Abstract
The utility model provides an operating mechanism of disconnector, its includes the base, is fixed to be set up the static contact on the base and fixes through the pivot moving contact on the base still is provided with the cantilever, cantilever one end is fixed to be set up in the pivot, the cantilever other end is provided with through inclined to one side compression spring is fixed on the base, compression spring is right partially a messenger has been applyed to the cantilever the pivot if the moving contact is kept away from the rotatory bias voltage power of static contact. The utility model discloses the technical problem that will solve lies in that the operating mechanism of disconnector disconnection back reset speed among the prior art is slow, and then provides the operating mechanism of disconnector that reset speed is fast. The utility model relates to a circuit breaker field, specifically speaking circuit breaker operating device.
Description
Technical field
This utility model is related to a kind of field of circuit breakers, specifically a kind of circuit breaker operation mechanism.
Background technology
Chopper be for can close, carry and cut-off the electric current under normal loop condition and can close, regulation
Carry and cut-off the switching device of the electric current under abnormal loop condition in time.
When abnormal conditions in loop or normally disconnecting, operating mechanism promotes moving contact support member so that dynamic/static contact is divided
Open, simultaneously lock and tripping unblock, and chopper is during disconnecting, because the power of operating mechanism is less, so chopper
It is difficult to upon opening reset, even resetting, the speed that it resets is also very slow.
Utility model content
For this reason, technical problem to be solved in the utility model is that the operating mechanism of chopper of the prior art disconnects
Reset speed is slow afterwards, and then provides a kind of operating mechanism of the fast chopper of reset speed.
For solving above-mentioned technical problem, a kind of operating mechanism of chopper of the present utility model, it includes pedestal, and fixation sets
The moving contact put in the static contact on pedestal and be fixed on by rotating shaft on described pedestal, is additionally provided with resetting means, described multiple
Position device includes cantilever, and described cantilever one end is fixedly installed in described rotating shaft, and the described cantilever other end passes through biasing force spring
It is fixedly installed on described pedestal, described biasing force spring is applied with one to described cantilever makes described rotating shaft described dynamic tactile to making
Head is away from the biasing force of described static contact rotation.
Described rotating shaft two ends are provided with described resetting means.
Described cantilever is set in described rotating shaft.
Described biasing force spring is extension spring.
Described biasing force spring is fixed on described pedestal by positioning piece.
Described keeper is cylinder, offers cannelure, described biasing force spring is set in described ring in the middle part of its axial direction
In shape groove, the other end hooks in the circular hole of described cantilever.
Technique scheme of the present utility model has advantages below compared to existing technology,
In the operating mechanism of chopper described in the utility model, it includes pedestal, is fixedly installed on the stationary contact on pedestal
Head and the moving contact on described pedestal is fixed on by rotating shaft, be additionally provided with resetting means, described resetting means includes cantilever, institute
State cantilever one end to be fixedly installed in described rotating shaft, the described cantilever other end is fixedly installed described pedestal by biasing force spring
On, described biasing force spring is applied with one and makes described rotating shaft to making described moving contact revolve away from described static contact to described cantilever
The biasing force turning.During on/off switch, operating mechanism can drive cantilever-rotating to chopper, so that spring elongation and receipts
Contracting, because the power of moment of closing a floodgate is very big, so spring will not produce impact to closing a floodgate to the counteracting force of chopper, and chopper
During separating brake, because mechanism's power of separating brake is less, so chopper is difficult to reset, reset speed is also slow, and this practicality
After the new biased power spring in the chopper left and right sides, during separating brake, biasing force spring has a power being pulled back to,
Chopper can be made reliably to reset, breaking speed also can be accelerated, further increase the reliability and security of chopper.
Brief description
In order that content of the present utility model is more likely to be clearly understood, it is embodied as below according to of the present utility model
Example simultaneously combines accompanying drawing, this utility model is described in further detail, wherein

Include cantilever 2, described cantilever 2 one end is fixedly installed in described rotating shaft, it is fixing that described cantilever 2 other end passes through biasing force spring 3
It is provided with described pedestal 5, described biasing force spring 3 is applied with one to described cantilever 2 makes described rotating shaft described dynamic tactile to making
Head is away from the biasing force of described static contact rotation.Cantilever 2 described in the present embodiment is set in described rotating shaft.Described biasing force bullet
Spring 3 is extension spring.Described biasing force spring 3 is fixed on described pedestal 5 by positioning piece 4.Turn described in the present embodiment
Axle two ends are provided with described resetting means.
Keeper 4 described in the present embodiment is cylinder, as shown in Fig. 2 offering cannelure in the middle part of its axial direction, described inclined
It is cylinder that compression spring 3 is set in described keeper 4 in described cannelure, offers cannelure in the middle part of its axial direction, described inclined
Compression spring 3 is set in described cannelure, and the other end hooks in the circular hole of mechanism's cantilever 2, and positioning and reseting procedure are more reliable.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Change among still in the protection domain of the invention.
