Description
Technical field
The present invention relates to the instrument of charged detection porcelain insulator in a kind of ultra-high-tension power transmission line, specifically a kind of porcelain insulator detects with angle self-locking sparking distance short circuit fork.
Background technology
Regulation according to " power equipment handing-over and preventive trial rules ", transmission line of electricity zero (low) value porcelain insulator carried out the deterioration rate in 1～3 year and detects, must finish by the cycle in the annual 3-5 month,, guarantee the safe and reliable of operation of power networks to guarantee the acceptance rate of equipment.The transmission line of electricity fed distance is long, and the porcelain insulator quantum count is many, and annual all have a large amount of porcelain insulator to need charged detection.In porcelain insulator subband electro-detection, the testing tool that generally adopts is that sparking distance short circuit fork is connected the zero detection operation boom end by bolt at present, become the U-shaped opening in the middle of the semicircle sparking distance short circuit fork body bottom, during use jaw bottom U-shaped opening is inserted on the screw rod of test rod, tighten with wing nut, its weak point is: on shaft tower during charged detection insulator, because the operating personnel is different with angle between every porcelain insulator, need draw back control lever repeatedly, constantly adjust the wing nut that sparking distance short circuit fork is connected with control lever, adjusting the jaw angle detects, operate loaded down with trivial details complexity like this, the operation hazard level is big, detection time is long, labour intensity is big, inefficiency.
Summary of the invention
The object of the present invention is to provide a kind of adjusting easy, simple in structure, easy making, be easy to carry, detecting operation fast, conveniently can shorten detection time, reduces labor intensity, increases work efficiency and reduce the porcelain insulator detection angle self-locking sparking distance short circuit fork of operation danger.
In order to reach above purpose, the technical solution adopted in the present invention is: this porcelain insulator detects with angle self-locking sparking distance short circuit fork, comprise insulcrete, contact, electrode, set bolt and mount pad, contact and electrode are respectively equipped with two, and be fixed on the insulcrete with set bolt respectively, two electrodes are corresponding, the contact of homonymy is connected with electrode, it is characterized in that: the lower end of described insulcrete is provided with rotary connector, rotary connector is located in the U-lag of rotation lock device, fixes mount pad in the lower end of rotation lock device.
The present invention also implements by following measure: described rotation lock device, constitute by U-lag, rotation lock device body, register pin, spring and sliding chamber, the upper end of rotation lock device body is a U-lag, evenly be provided with arc groove on the edge of rotary connector, be provided with sliding chamber at the middle part of rotation lock device body, in sliding chamber, be provided with register pin and spring, spring is positioned at the bottom of register pin, the front end of register pin is corresponding with the arc groove of rotary connector, fixes mount pad in the lower end of rotation lock device body.
Beneficial effect of the present invention is: regulate easy, simple in structure, easy making, be easy to carry, detecting operation fast, conveniently, shortened the time of charged detection insulator, shortened to every basic 23 minutes of detection in every basic 36 minutes by original detection, reduce operating personnel's labour intensity, strengthened the safety coefficient of operation, improved work efficiency.
