Abstract

The present invention discloses a sampling valve installation structure of the resistive leakage current of the arrester, which comprises a sampling valve and an installation mould; the sampling valve consists of a plurality of valve layers which are tightly pressed together; each valve layer consists of two copper pieces and a valve which is clamped between the two copper piece; and the sampling valve is arranged in the installation mould, and is solidified with the installation mould in an insulating way through the epoxy resin to form an integrated body. The installation structure of the sampling valve of the resistive leakage current of the arrester has the following advantages: firstly, the residual voltage after the impact of the large current appears is low; and secondly, the installation process is simple.

Description

technical field [0001] The invention relates to an installation structure of a sampling valve plate for resistive leakage current of a lightning arrester. Background technique [0002] Zinc oxide arrester is a kind of protective equipment to protect electrical equipment from overvoltage. Due to the superior nonlinear characteristics and good flow capacity of the zinc oxide arrester, it has been accepted and widely used by users in the power sector. Damage and electrical accidents occur from time to time, especially for 110KV and above voltage level zinc oxide arresters, once an accident occurs, it will cause huge losses to users. [0003] It is very important to test the performance of the arrester under the operating voltage. How to accurately obtain the leakage current of the arrester is the key to accurately detect the performance of the arrester. Although a variety of technical measures have been taken over the years, due to the detection device and method, the detect...
