Description

Clothoid type self-balancing anti-shock arrester

Technical field

The utility model relates to power equipment, especially relates to a kind of Clothoid type self-balancing anti-shock arrester that is used for transmission line.

Background technology

The damage to crops caused by thunder tripping operation of 220kV and above transmission line basically all is to be caused by around shocking; The application of anti-shock arrester has great significance to the lightning protection of 220kV and above transmission line; From anti-shock arrester in recent years should be used for see; The circuit of anti-shock arrester is installed, and the thunderbolt trip-out rate obviously reduces.

Beginning in 2005, China 220kV and above transmission line are installed anti-shock arrester in a large number, and the installation of anti-shock arrester greatly reduces the thunderbolt trip-out rate.

But after circuit is installed anti-shock arrester in a large number, increased very big workload for circuit operation maintenance unit, because the upset of lightning rod ubiquity, the slippage of using at present, fall phenomenon such as pin, particularly lightning rod upset, very general.Its main cause is that ground wire received weather influences such as icing after lightning rod was installed on the ground wire, and stress changes; Cause ground wire to twist; Lightning rod also follows ground wire to reverse together, and the lightning rod after reversing can't effectively reduce shielding angle, thereby loses lightning protection capability.

In addition, common anti-shock arrester installs very trouble, and skilled trackman on average can only install a base for each person every day.Its reason is that the workman is being with lightning rod that lightning rod is installed on ground wire, and after adjusting angle; Get back on the shaft tower, ground wire has lost the effect of people's gravity, and stress changes; Ground wire reverses, and lightning rod and then reverses, and the workman gets the adjustment of outlet once more; So back and forth, workload is very big, and is difficult to adjust to desirable angle.

Also there is the shortcoming that installation cost is high, maintenance workload is big in the anti-shock arrester of present domestic widespread usage.

Summary of the invention

The purpose of the utility model is to provide a kind of and can overturn along with ground wire upset, lightning rod remains specific angle, remain unchanged, not slippage, do not fall pin, reliable, the non-maintaining Clothoid type self-balancing anti-shock arrester of simple installation.

The purpose of the utility model is achieved in that

A kind of Clothoid type self-balancing anti-shock arrester; Characteristic is: be made up of left self-balancing base, right self-balancing base, left needle body, right needle body, counterweight and ground wire chuck; Left side self-balancing base and right self-balancing base connect together through the last hinge on top; Left side needle body, right needle body are separately fixed on the lateral wall of left self-balancing base and right self-balancing base; Be processed with left kidney slot in the centre of left self-balancing base, be added with the right mounting hole under shed in the lower end of right self-balancing base, fastening bolt passes behind right mounting hole and the left kidney slot middle part that the lower end of left self-balancing base is fixed on right self-balancing base; Be processed with the inverted U-shaped right compensating groove under shed in the lower end of right self-balancing base, counterweight is installed in the lower end of the support arm at right compensating groove two ends through down hinge; Be processed with relative left semicircle groove of opening and right semi-circle groove respectively on the top of left self-balancing base and the top of right self-balancing base; Left semicircle groove and right semi-circle groove constitute the ground clamp grooving of inner wall smooth altogether; Center fixed have the smooth ground wire chuck of ground wire and outer wall by left self-balancing base and right self-balancing base double team in the ground clamp grooving, and left self-balancing base, right self-balancing base, left needle body, right needle body and counterweight together can be around ground clamp interplanting relative motions.

The ground wire chuck is formed by four bolt of two semi-circular axle clamp plates through the rear and front end; Inwall at two semi-circular axle clamp plates is coated with conductive rubber; To prevent that the local stress that lightning rod contacts with lightning conducter (being ground wire) from concentrating, avoid lightning rod damage lightning conducter.

The utility model is made up of left self-balancing base, right self-balancing base, left needle body, right needle body, counterweight and ground wire chuck; After two semi-circular axle clamp plates of ground wire chuck are wrapped in the centre with lightning conducter; Four bolts through the rear and front end are fixed on the ground wire chuck on the lightning conducter; Open the left self-balancing base and the right self-balancing base lower end that connect together of top then; Make the ground wire chuck be positioned in the ground clamp grooving; After last fastening bolt passes left mounting hole and right kidney slot right self-balancing base and left self-balancing base are fixed together, so left self-balancing base, right self-balancing base, left needle body, right needle body and counterweight together can be around ground clamp interplanting relative motions.The lightning rod below is equipped with counterweight, makes lightning rod in the vertical plane of lightning conducter, can freely rotate, and under gravitational effect, no matter how lightning conducter reverses, lightning rod remains specific angle, remains unchanged again.

The utility model is connected with bearing pin with bolt, and simple installation is reliable, and it has solved the high problem of installation cost, safeguards to become very easy, has reduced the installation and operation cost, really accomplishes non-maintaining.

Therefore, not the utlity model has can overturn along with the ground wire upset, lightning rod remains specific angle, remain unchanged, not slippage, do not fall pin, reliable, the non-maintaining advantage of simple installation.
