Description
Technical field
The utility model relates to the emergent only heat of a kind of 220kV GW7 disconnecting link pincers, belongs to the technical field of electric power system operation safe device.
Background technology
Administer 22,220kV electric substation in the checking experiment work area, 124 groups of existing GW7 disconnecting links, annual heat supply in winter, summer is while irrigating oepration at full load, because disconnecting link static contact finger structure inner spring is aging, surface oxidation, the reasons such as environmental pollution, climate change, the disconnector contact-finger superheating phenomenon that quantity does not wait all can appear in every year, to system safety operation, brings very large threat.During the grid power blackout maintenance, can affect power supply reliability again, in the Ying Fengdu summer, meet peak and cross the particular time in winter, electric power is all near oepration at full load mostly, while at this moment wanting interruption maintenance disconnecting link overheating fault, is exactly very difficult, for this situation, it is exactly necessary developing a kind of only heat pincers that just can process overheating fault that need not have a power failure.
The staff was connected between wire and conducting rod with short line in the past, the danger of the method operation is very large, very easily cause distance to the ground not enough, at least needing four people of three insulating bars to cooperatively interact during operation just can complete, and wire is difficult to when vertical install, add that as short line gold utensil weight reaches tens jin, length reaches more than 800 millimeters.Adopt now wooden contract nail between rain cover and fingertip, increase the clamping force between fingertip and contact, solve the overheated problem of disconnecting link temporarily, this processing procedure needs three people to complete at least.Although the method is feasible, implement cumbersome, follow closely the disconnecting link after wooden contract, when operating, the operations staff sometimes breaks not open, affect operations staff's normal running, wooden contract must be taken off just and can be operated, and can only just can carry out after power failure while getting wooden contract.Burn in order to prevent disconnecting link from continuing overheated, do not have a power failure as far as possible, use the fastest time to process.
The utility model content
In order to solve above-mentioned problems of the prior art, the utility model provides the emergent only heat of a kind of 220kV GW7 disconnecting link pincers, purpose be for provide a kind of safe and reliable, simple in structure, do not need to have a power failure, single use insulating bar is removable emergent only heat pincers.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The emergent only heat of 220kV GW7 disconnecting link pincers, be connection fixing block below parallel baffle, and fixed block is connected with the plate washer support; Be connected with the insulating bar connector on the plate washer support; The other end of plate washer support is connected with the L baffle plate; One end of L baffle plate is connected with the Self-adjustment parallel baffle; The L baffle plate other end is connected with the insulating bar connector.
Be set with spring on the screw mandrel on described insulating bar connector top.
Described fixed block and bottom are provided with screw hole, by two roll adjustment screws, with the plate washer support vertical, are connected.
On described plate washer support, a through hole is established at middle part, passes the insulating bar connector in hole.
The other end of described plate washer support is connected by the second pivot pin with the L baffle plate of L shaped shape, and L baffle plate one end is connected with the Self-adjustment parallel baffle by the first pivot pin; The L baffle plate other end and insulating bar connector top spring overlap joint.
Described L baffle plate is the baffle plate of L shaped shape.
Advantage of the present utility model and beneficial effect are: the utility model be a kind of safe and reliable, simple in structure, do not need to have a power failure, single use insulating bar is removable emergent only heat pincers.Have characteristics easy and simple to handle, safe and reliable.The quantity that can also significantly reduce a staff, and shorten working hours, rapidly removing faults, be significantly improved operating efficiency.The utility model is suitable to vast electric power system promotion and application.
