A clamp force locking and releasing device is arranged in the wiring pliers. Pluggable connecting terminals are arranged on upper and lower sides of the wiring pliers. According to the utility model, the professional problem of transformer test with cooperation of an insulation bucket arm vehicle and an artificial lift platform is thoroughly solved, scheduled outage time of a transformer is reduced, and economic benefit of a power grid is raised.
Description
Technical field
The utility model relates to a kind of power system device field adjustable device, relates in particular to a kind of 220kV transformer test short-circuit wiring connector.
Background technology
As 23, the condominium linchpin 220kV of an electric company electric pressure transformer, according to power transmission and transformation repair based on condition of component cycle request, annual is carried out routine test nearly 8 times, does not wherein comprise that industry expands, and after the overhauls such as overhaul and newly-built substation project, with check, tests.After transformer routine and overhaul and the check pilot project, be for ensureing the 220kV transformer station rear safe and reliable operation that puts into operation, the pilot project that must detect.While completing above-mentioned pilot project in the past, mainly to carry out test connection connection, change and short-circuit line by testing crew climbing transformer high-voltage bushing to connect, the transformer top is to average 3 meters of bushing, complete the inferior test of 1 platform, testing crew need be climbed for more than 20 times, and labour intensity is large and have a serious potential safety hazard.And the regulation bushing shell for transformer is forbidden to climb, must adopt the aerial lift device with insulated arm compatibility test, but part transformer station, tool car can't approach main transformer, can only adopt the hand lifting/lowering platform to carry out operation, plan like this testing operation test and just by original 2 days, be increased to 4 days, have a strong impact on the economical operation of electric power system, because other equipment of operation field keep running status, therefore adopt above-mentioned two kinds of operational methods to have very big loss of life or personal injury and device damage hidden danger simultaneously.
Summary of the invention
The utility model is for above-mentioned problems of the prior art, a kind of 220kV transformer test short-circuit wiring connector that does not use aerial lift device with insulated arm and hand lifting/lowering platform just can complete the whole wiring of transformer test operation is provided, solve in prior art efficiency low, had the problem of potential safety hazard.
The technical solution of the utility model is as follows:
Comprise back-up system and connected system, connected system is arranged on the top of back-up system, and back-up system is the more piece insulating bar; Connected system forms jointing clamp by regular jaw and moved jaw, and jointing clamp inside is provided with folder power lock release, and the plug binding post is arranged on the both sides up and down of jointing clamp.
Described insulating bar is comprised of three grades of extensible link, and resistant to bending stresses is greater than 35kg, and weight is less than 3kg.
Between described regular jaw and moved jaw, by machine driving, connect.
Described folder power lock release is to be provided with the Mainspring type spring in the jointing clamp draw-in groove.
Described connected system and transformer contact site, area is greater than 1.3 square centimeters, and bite stress is greater than 20kg.
Described connected system is connected with back-up system by steering union joint, and connected system coupling part deflection angle is greater than 90 °.
The utility model has the advantages of as follows:
1, simple to operate, with action bars, the jaw of jointing clamp is hung tag on the position of wiring, by pushing away, the pulling process bar, can make the jaw free-open-close, complete wiring work.
2, coupling part is practical, and the jaw angle of jointing clamp can change, and can complete wiring position different angles different-thickness different-diameter, height in the test job requirement below 8 meters.
3, overall weight is little, uses light.Reasonable in design, excellent in quality, durable in use.
4, folder power lock release has the function that locking, recovery, jaw are unclamped, and retraction force is greater than 10kg;
During pull joystick, can make automatic locking on the jaw dynamics that will clamp of what is the need in office.While promoting action bars, can make the jaw clamped open.If inartificial promotion operating arm dedicated, the self-locking device in pincers will not make the jaw oneself clamped open, safe and reliable.
5, needing aerial lift device with insulated arm and hand lifting/lowering platform just can complete the scene of transformer test operation, adopt the present invention, testing crew needn't be climbed bushing shell for transformer or complete testing operation by aerial lift device with insulated arm and hand lifting/lowering platform, as long as testing crew stands in the transformer top transformer test short-circuit wiring connector is connected to transformer one successively, secondary sleeve pipe top, just can complete smoothly the total Test wiring work of transformer, thoroughly solve the problem that adopts aerial lift device with insulated arm and hand lifting/lowering platform to coordinate the transformer test specialty, reduce the transformer scheduled outage time, improve the electrical network economy benefit.
