Description
Technical field
The utility model is related to test of lightning arrester pressurization lead support device, specifically a kind of 110kV and more than arrester
Carry out leakage current test pressurization lead support device under the voltage and 75% voltage under direct current 1mA.
Background technology
Arrester is the important equipment in electric system, and main function is to prevent thunder and lightning from being damaged to equipment, and it is fixed to need
Phase carries out arrester leakage current test under voltage and 75% voltage under direct current 1mA, to judge the healthy shape of arrester
State.
At present when carrying out 110kV and the power failure experiment of above arrester, due to test voltage height, pressurization lead
Over the ground, certain stray electrical current, leakage current flow through insulation stent and neighbouring device.These electric currents have flow through it is lightning-arrest
Leakage current inside device has the stray electrical current of shielding line over the ground, there is stray electrical current of the pressurization lead to adjacent equipment, and pressurization is drawn
Stray electrical current caused by line is very big on the result influence of experiment, and below 110kV voltage class test of lightning arrester voltages are relatively low, therefore
It need not consider influence of the stray electrical current to result of the test.
In order to improve the accuracy of experiment, pressurization lead is needed with arrester as possible into 90 degree, and pressurization lead and arrester
Ontology holding distance enough is simultaneously hanging, at present when being tested, usually stretches pressurization lead with phase colour band, ties up in other frameworks
It waits on insulators, the method is difficult to ensure that above-mentioned two test condition, causes test data precision low, need to repeatedly measure, and influences
Working efficiency.
CN104237571A discloses a kind of pressurized line support device for test of lightning arrester, including insulating bar and installation
Gold utensil on insulating bar top, insulating bar are parallel with arrester；Gold utensil includes a long contact, and long contact one end is hung down with arrester
It is straight to be connected, other end connection pressurized line.In the present solution, long contact can make to keep between arrester and pressurized line it is enough away from
From and long contact gold utensil acts as a part of p-wire, ensure that vertical between pressurized line and arrester, can greatly improve
The accuracy of test value can solve above-mentioned problems of the prior art.But the support device is in use, the length of gold utensil is touched
Head acts as a part of p-wire, and due to the exposure of long contact in air, there is stray electrical current in when pressurization to surrounding air, causes to try
Test data inaccuracy.In addition, the support device is connect with arrester using gold utensil and erects insulating bar, filled without special support
It puts and insulating bar is supported, be not sufficiently stable.Therefore, it is necessary to a kind of pressurized line support devices reliable and easy to operate to solve
The certainly above problem.
Utility model content
The purpose of this utility model be in view of the deficiencies of the prior art, and provide it is a kind of simple in structure, it is easy to operate, stablize
Property it is good, reliability is high, light weight, mounts and dismounts all convenient 110kV and more than test of lightning arrester pressurization lead support device.
Realizing the technical solution of the utility model aim is：
A kind of 110kV and more than test of lightning arrester pressurization lead support device including A-frame and are threaded through triangle branch
The multi-stage expansion insulating bar at frame center, unlike the prior art：The top connection screw thread of the multi-stage expansion insulating bar connects
Head is equipped with corner coupling head on nipple；It further includes the horizontal stand of drum type brake hollow-core construction and is matched with horizontal stand and matched
The three-way connection of dress, horizontal stand pass through the both ends of three-way connection, and the other end and the corner coupling head of three-way connection are equipped with, arrester
Experiment pressurization lead is connected across horizontal stand with arrester.
The bottom end of the multi-stage expansion insulating bar is fixedly connected with pedestal, and iron plate of the pedestal for square is exhausted to multi-stage expansion
Edge bar plays supporting ＆ stablizing.Multi-stage expansion insulating bar, one shares 4 sections, is made of epoxide resin material.
The horizontal stand is made of epoxide resin material, and corner coupling head and three-way connection use polythene material system
Into horizontal stand passes through the both ends of three-way connection, can be moved left and right at the both ends of three-way connection.
The A-frame be the prior art, three foldable contractions of foot, multi-stage expansion insulating bar pass through A-frame
Center, open A-frame and stabilization risen to multi-stage expansion insulating bar.
The utility model support device is used to support and fixes test of lightning arrester pressurization lead so that pressurization lead is with keeping away
Thunder device keeps 90 degree of angle, and passes through the pedestal support of A-frame and multi-stage expansion insulating bar so that pressurization lead is stablized
Enough safe distances are vacantly kept with arrester, pressurization lead passes through horizontal stand, considerably reduces it to the miscellaneous of air
Electric current is dissipated, improves the accuracy of arrester power failure experimental test, excludes interference of the human factor to test data, improves work effect
Rate.
