Description

Special support for distribution type zinc oxide arrester test

technical field

The invention relates to an electric power test tool, which is mainly used as a special support for the test of the distribution type zinc oxide arrester during the leakage current test and insulation resistance test of the distribution type zinc oxide arrester.

Background technique

Due to the advantages of small size, light weight, impact resistance, and flexible installation, distribution type zinc oxide arresters are widely used in 6~35kV power main transformers, switch cabinets, box-type transformers, and power cables. Before the arrester is put into operation, and when the operation time of the arrester in operation reaches the specified test period, it is necessary to perform a leakage current test and an insulation resistance test on the arrester. In order to avoid the impact of lines or other electrical equipment on the test data, the arrester to be tested is usually removed. When doing the leakage current test and the insulation resistance test, since the applied voltage is as high as several thousand volts or even tens of thousand volts, the arrester cannot be directly placed on the ground to prevent the arrester from discharging to the ground. The testers need to temporarily build a test platform, suspend the arrester in the air with ropes, and then conduct the test. It takes a long time to build the test platform and fix the arrester, and there is a risk of the arrester falling during the test.

Contents of the invention

The purpose of this utility model is to design a special support for the test of distribution type zinc oxide arrester. In order to achieve the above purpose, the technical solution of this utility model is:

The special support for distribution type zinc oxide arrester test, including telescopic support, is characterized in that: the telescopic support is connected with a disc, the disc has a round hole, the telescopic support has fixing holes, and the fixing holes are stretched and contracted by bolts, and the telescopic support The bottom is provided with a stable chassis, and the stable chassis has a fixing groove corresponding to the fixing protrusion at the bottom of the telescopic bracket, and the bottom of the stable chassis has anti-skid lines. The utility model is safe in use, convenient to carry, and greatly reduces the danger of users.

Detailed ways

The device is similar to the base of a camera stand, and the three supporting legs of the base can be extended and retracted, and can also be folded and unfolded, so as to be convenient to carry. Weld a metal disc on the base, and punch a round hole in the middle of the metal disc. During the test, the arrester and the metal disc are kept in a vertical position, the grounding end of the arrester (a threaded metal rod) is passed through the round hole, and is fixed with a nut on the bottom of the disc. The clamp of the test grounding wire is clamped on the metal disc, and the terminal of the arrester is suspended vertically and connected to the high voltage end of the test test line.
