Description
Technical field
The present invention relates to technical field of electric power, especially a kind of pressurized line support meanss for test of lightning arrester.
Background technology
In power system, it is generally the case that high-voltage connection and high-voltage output end expose in atmosphere, its over the ground, it is right
Insulation stent and neighbouring device have certain stray electrical current, leakage current to flow through, and the result of test of lightning arrester is affected very
Greatly.
In order to cut down the impact of stray capacitance, most easily means of testing improved method is to change high-voltage output line and take shelter from the thunder
Angle high-voltage output line and lightning arrester body in 90 ° is simultaneously installed by the distance between device body, so can greatly improve test
The accuracy of value.When therefore doing leakage current of an arrester test, for the accuracy for ensureing to measure, measure traverse line should be with spark gap
Body is tried one's best at an angle of 90, while noticing that pressurized line maintains enough distances with spark gap metal shell.
And when spark gap field test works, due to being limited by field test condition, we are often pressurization wire clamp
On the gold utensil contact on insulating bar top, then insulating bar is hung over the high-pressure side of spark gap.Due to insulation ready-made on market
Bar gold utensil contact cannot be rotated and short and small（Lengths of contacts is no longer than 15cm）, so it is difficult to ensure that pressurized line and spark gap sheet
Body angle in 90 °, while pressurized line is also difficult to ensure that enough distances with spark gap metal shell, when electric pressure is higher
（110kV and above）, test bit is alternate, interindividual variation is very big, and the error for causing is particularly evident；In addition, city
On field, ready-made short and small contact gold utensil is limited because contact size is short and small when circulation is repeatedly measured, and needs testing crew to move repeatedly
Test instrunment, causes work efficiency low.
The content of the invention
The technical problem to be solved in the present invention is that：For the problems referred to above that prior art is present, the present invention provides one
Simple and compact for structure, low cost, the pressurized line support meanss for test of lightning arrester easy for installation are planted, the pressurized line clamps work
Tool can increase the distance between spark gap and pressurized line, and pressurized line is installed with spark gap angle in 90 °, greatly can carry
The accuracy of high test value.
For achieving the above object, the pressurized line support meanss for test of lightning arrester of the invention, including insulating bar and peace
The gold utensil on insulating bar top is mounted in, above-mentioned insulating bar is parallel with spark gap；Above-mentioned gold utensil includes a long contact, long contact one end
It is vertically connected with spark gap, other end connection pressurized line.In this programme, long contact can make to keep between spark gap and pressurized line
Enough distances, and long contact gold utensil act as a part of p-wire, it is ensured that it is vertical between pressurized line and spark gap, can pole
The earth improves the accuracy of test value.
As a further improvement on the present invention, rotating disk is installed on above-mentioned gold utensil, is flexibly connected gold utensil and insulating bar,
So as to adjustable gradient of the gold utensil on insulating bar, and then adjust the angle on gold utensil between long contact and spark gap.
Further, to make above-mentioned pressurized line clamping device be applied to the measurement of differing heights, above-mentioned insulating bar is scalable
Structure.
Preferably, above-mentioned gold utensil is made using pyrite.
Relative to prior art, the invention has the advantages that and beneficial effect：
1st, in the present invention, gold utensil adopts long contact, can make enough distances are kept between spark gap and pressurized line, improves
The accuracy of test value；
2nd, in the present invention, long contact gold utensil act as a part of p-wire, it is ensured that hanging down between pressurized line and spark gap
Directly, the accuracy of test value can be greatly enhanced；
3rd, in the present invention, rotating disk is installed on gold utensil, the gold utensil angle of inclination on insulating bar can be adjusted by rotating disk,
While insulating bar adjustable in length, highly versatile；
4th, the simple compact, low cost of present configuration, easy for installation.

Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not
It is only limitted to this.
【Embodiment 1】
As shown in Figure 1, Figure 2 and Figure 3, the pressurized line support meanss for test of lightning arrester of the present embodiment include insulating bar
2 and installed in the gold utensil 3 on 2 top of insulating bar, wherein：Insulating bar 2 is parallel with spark gap 1, and gold utensil 3 includes a long contact 31,
31 one end of long contact is vertically connected with spark gap 1, other end connection pressurized line 4.In Fig. 1,6 is microampere meter, and 7 is test system.This
In embodiment, long contact 31 can make enough distances are kept between spark gap 1 and pressurized line 4, and the long contact 31 of gold utensil 3 fills
When a part of p-wire, it is ensured that vertical between pressurized line 4 and spark gap 1, the accuracy of test value can be greatly enhanced.
