Description
Technical field
The present invention relates to arrester the field of test technology, are specifically related to a kind of dedicated reality for lightning arrester live-line test
Test bar.
Background technique
There are two outstanding problems when electrical test class is for arrester progress live detection work:
(1) wiring is cumbersome, and testing efficiency is lower: needing to pick up test line in arrester discharge counter upper and lower ends, but keeps away
Thunder device discharge counter is usual liftoff higher (2.4m-2.6m), so needing testing crew to scale a ladder to complete assembly and disassembly line
Work.When carrying out whole station lightning arrester live-line test, need repeatedly from ladder high and low, it is such to connect mode of taking out stitches on the one hand
Taken a long time so that testing efficiency is lower, still further aspect to testing crew bring it is certain drop risk, in addition, repeatedly carrying
Ladder compares the physical strength of consumption test personnel, so that testing crew is quite tired out.
(2) live line connection has person electric shock risk: directly wearing insulating glove with manpower and take out stitches come connecing when being tested,
If not paying attention to keeping safe enough distance, the position that arm is stretched is excessively high, may cause lead of high pressure directly to human body discharge,
Lead to serious human casualty accident.
It needs to design a special equipment for arrester live detection, to improve efficiency, simplify work step, mention
High safety index.
Summary of the invention
In order to overcome existing method there are the shortcomings that, the present invention designs a arrester live detection Special test bar, keeps away
Exempt from using and carrying for ladder, eliminate the work of climbing of staff, improves arrester live detection efficiency.
The present invention provides a kind of Special experimental bar for lightning arrester live-line test, and upper end conductive structure (1) is in question mark shaped,
It is provided with arc sections (101), centre is provided with branch (103), and terminals (102) are arranged in the end of branch (103), lower end setting
There are threaded portion (104)；Conductive structure (1) is connected through a screw thread by the threaded portion (104) of its lower end with connector (2), i.e. spiral shell
Line portion (104) is provided with external screw thread, and connector (2) is provided with internal screw thread, connector (2) and first segment insulating bar (4) fixed company
It connects, 5 section insulating bars (4) are linked together by 4 fasteners (3), form section formula of taking out, Section of five insulating bar (4) lower end setting
Insulated handle (5)；4 section insulating bar (4) of top is shrinkable to enter, also it is stretchable come out, fastener (3) can after shrinking or
Insulating bar (4) is fixed after stretching, slips insulating bar (4) not.
Fastener (3) and insulating bar (4) are that insulating materials is made, and it is that conductive material is made that conductive structure (1) is whole；
The length of every section insulating bar (4) is 60-90cm, total length 4-4.5m after test club stretches, and the length after contraction is 90-
120cm。
Application method of the invention are as follows:
P-wire is connected on the terminals of conductive structure, the arc sections of the conductive structure of test club are mounted on arrester meter
At number device upper end lead, to realize the connection of p-wire Yu arrester to be measured, every testing experiment is then carried out, test is completed
Afterwards, remove test club.
The beneficial effects of the present invention are:
1, reliable performance: p-wire is connected on conductive conductive structure, and is mounted its front-end architecture using insulating bar
The connection of measurement lead and tested device is realized at the lead of counter of lightning arrester upper end, check bar can be reliably connected test
Lead and counter terminals, meet live safety requirement, provide reliable safety to personnel during entire test and equipment
It ensures；
2, it improves efficiency: avoiding using and carrying for ladder, eliminate the work of climbing of staff, improve arrester band electric-examination
Efficiency is surveyed, the amount detection of arrester in the unit time is increased；
3, reduce risk: realization replaces manpower with arrester reference test bar connect the work taken out stitches, and reduces person electric shock, height
Empty falling risk, reduces the labor intensity of staff, while significantly improving the safety of this work, reduces wiring people
The person electric shock risk of member；
4, at low cost, structure is simple, portable, easily promotes: material selection carries out selection in line with economic, practical, safe angle, adopts
With qualified light weight insulating material, low in cost, structure is simple, small in size, is convenient for carrying and uses, durable, in electric power
Industry, which is promoted, to be easy.It is adjustable to test pole length, can be adapted for the test of the arrester of a variety of height.
