Its drive disk assembly can be aoxidized progressively, corrosion, loosening, there is familial defect, cause disconnecting link to go out in grid switching operation in part disconnecting link
Now divide, close a floodgate exception defect.
Such as SPV, GW10, GW22, GW16/17 single-pole vertical cut-off folding-jib disconnecting link, and dynamic and static contact occurs in separating brake
Kill, moving contact is opened not open and the separating brake that cannot be well on, can also occur during combined floodgate such as the conductive arm slightly only situation at dead point.Again
Such as SPO, GW23, GW11, GW17 double-column horizontal cut-off folding-jib disconnecting link, moving contact can occur withstand on static contact when closing a floodgate to hold
Mouthful edge and the combined floodgate that cannot be well on.
Current processing method has：One is that temporary interruption is overhauled or adjusted the method for operation, by directly to the steady of system
Fixed operation brings very big influence；Two are with the powered drawing of Conventional insulation rod or push the positions such as contact or conductive arm, but such
Greatly, success rate is not also high for operational danger.So, it is badly in need of developing special operation auxiliary Work tool, may be implemented in powered feelings
Safe and effective compounding practice under condition.
The content of the invention
It is a primary object of the present invention to overcome deficiency of the prior art, there is provided a kind of disconnecting switch of new structure
Separating brake aids in Work tool with emergent extremely, and it has compact conformation, convenient disassembly, makes easy, safe and reliable, practical
Advantage, the abnormal conditions that dynamic and static contact is killed during not only for disconnecting switch separating brake can be slightly spaced its moving contact, smoothly
Realize separating brake；And make it by way of on-line treatment in place, reduce the non-safe operation for stopping number of times, equipment not being influenceed, drop
The security risk of low temporary downtimes repairing, improves equipment operational reliability, has the value in industry.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of disconnecting switch separating brake is extremely with emergent auxiliary Work tool, including the vertical hanging board that is made of insulating materials and level

Wherein, the vertical hanging board is disposed with retainer ring and spacing ring, the spring along central axis from top to bottom
Top be fixed on retainer ring, the bottom of spring is connected with vertical rod, the vertical rod penetrates spacing ring and by being fixedly arranged on vertical rod
The limited block of shaft is connected with vertical hanging board support；One end of the pressure pin and the vertical rod shaft between spring and spacing ring
It is hinged, the other end of pressure pin is connected with the bottom surface of horizontal shelf；The vertical hanging board is additionally provided with support ring, and the pressure pin is passed through
It is connected with vertical hanging board through support ring.
The present invention is further arranged to：The top surface of the vertical hanging board is provided with rain cover.
The present invention is further arranged to：The suspension member is linked up with for curved arc shape.
The present invention is further arranged to：The suspension member is inverted U button suspension member.
The present invention is further arranged to：The retainer ring and spacing ring are respectively arranged on the top and bottom of vertical hanger.
The present invention is further arranged to：The bottom of the vertical rod is provided with draw ring.
The present invention is further arranged to：The shaft of the vertical rod is coated with anti-skidding insulating barrier.
The present invention is further arranged to：The vertical rod includes the fix bar being connected with spring and stretching positioned at bottom of fixed
Contracting bar.
Compared with prior art, the invention has the advantages that：
By the setting of vertical hanging board and horizontal shelf, and the interaction relation of spring, vertical rod and pressure pin setting, hanging down
Direct screening plate in the case that static contact top surface, horizontal shelf support prop up moving contact bottom surface, pulls downward on vertical rod by suspension member lodge
So that pressure pin drives moving contact to be slightly spaced with support ring as fulcrum holds up horizontal shelf, so that realize smooth separating brake, i.e.,
Can be used under electriferous state carry out sub-switching operation, it can also be used to the artificial separating brake under power down mode；By way of on-line treatment
Make separating brake in place, the non-security risk stopped number of times, reduce temporary downtimes repairing can be reduced, improve equipment operational reliability；And use
In power failure separating brake, quick, safe and reliable operation is capable of achieving, it is ensured that maintenance is efficient.
