Abstract
A high-voltage switch contact resistance test bar is provided with an insulating bar, an insulating board is fixed at the upper end of the insulating bar, two sides of the insulating board are symmetrically and penetratingly provided with contact pin screws, an adjusting nut and a connecting nut are sequentially disposed on each contact pin screw under the insulating board, and pressure springs are respectively sleeved on the contact pin screws inside the insulating board. The high-voltage switch contact resistance test bar has the advantages that the test bar replaces the traditional step ladder with the insulating rod, replaces a connecting clamp of a testing wire with the contact pin screws, and uses the connecting nut to be connected with the testing wire, thereby realizing a contact resistance test of a high-voltage switch by replacing overhead working with ground working; the test bar is simple in structure, convenient in use, high in work efficiency and fine in safety performance, and can test contact resistance of the high-voltage switch without setting and climbing the step ladder; and the test bar can ensure the front end of each contact pin screw to reliably contact with a connecting terminal of the high-voltage switch as the contact pin screws have certain elasticity under the action of the pressure springs, and then can test contact resistance accurately, conveniently and quickly.
Description
Technical field
The utility model is particularly related to a kind of high-voltage switch gear contact resistance reference test bar.
Background technology
There are a lot of high voltage substations in China, many high-voltage switch gears are used in the high-voltage transforming standing-meeting, as 220KV isolating switch, 220KV disconnector etc., therefore the annual contact resistance test that all will carry out high-voltage switch gear, the connection terminal of this need of work in the high-voltage switch gear both sides respectively connects two balanced bridge p-wires, measures contact resistance.Because porcelain equipment No climbing, therefore at present the maintainer is measuring high-voltage switch gear for example during the contact resistance of 220KV isolating switch, two six meters fork ladders are set up in employing in 220KV isolating switch both sides, need eight people to erect the fork ladder, two maintainers are being with p-wire binding clip climbing ladder to carry out wiring, need for a long time, not only influence work efficiency and work quality, and can have certain danger, also be difficult to reach simultaneously standardization, normalized requirement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, need not to set up, climb the contact resistance that the fork ladder just can be measured high-voltage switch gear, high efficiency, the high-voltage switch gear contact resistance reference test bar that security performance is good.
The utility model is achieved in that it has an insulating bar, upper end at insulating bar is fixed with insulcrete, symmetria bilateralis at insulcrete is penetrated with the contact pilotage screw rod, on the contact pilotage screw rod, be positioned to be provided with successively below the insulcrete and adjust nut and wiring nut, on the contact pilotage screw rod, be positioned at insulcrete and be with pressure spring respectively.
Above-mentioned high-voltage switch gear contact resistance reference test bar is provided with a screw rod in the upper end of insulating bar, described insulcrete middle part is through on the screw rod and by nut to be fixed.
Above-mentioned high-voltage switch gear contact resistance reference test bar, the front end of described contact pilotage screw rod is provided with screw thread for most advanced and sophisticated, rear portion, be provided with the annular snap edge at the middle part of contact pilotage screw rod, correspondence runs through contact pilotage screw rod place and is provided with shoulder hole on insulcrete, described pressure spring one end withstands on annular snap along last, and the other end withstands on the ladder place of shoulder hole.
Above-mentioned high-voltage switch gear contact resistance reference test bar, described insulating bar are to be formed by connecting by screw-casing by four pole bodies, so that use and carry.
The utility model has the advantages that: can replace traditional fork ladder by insulating bar, the binding clip that can replace p-wire by the contact pilotage screw rod, connect p-wire by the wiring nut, therefore this high-voltage switch gear contact resistance reference test bar has been realized replacing work high above the ground to finish the contact resistance test of high-voltage switch gear at Ground Operation, simple in structure, easy to use, need not to set up, climb the contact resistance that the fork ladder just can be measured high-voltage switch gear, high efficiency, security performance is good; Because the contact pilotage screw rod has certain retractility under the effect of pressure spring, can guarantee that the contact pilotage screw front end contacts with the reliable of high-voltage switch gear connection terminal, it is accurate, convenient, fast therefore to measure contact resistance.
