The invention provides a thyristor valve type controllable lightning arrester support, an integrated structure and an anti-seismic verification method. The support comprises a lightning arrester support; a thyristor valve support which is arranged on one side of the lightning arrester support, wherein the thyristor valve support is connected with the lightning arrester support; the thyristor valve maintenance platform is arranged on one side of the thyristor valve support and the lightning arrester support, the thyristor valve maintenance platform is connected with the thyristor valve support, and the thyristor valve maintenance platform, the thyristor valve support and the lightning arrester support form an integrated structure. According to the controllable lightning arrester, the lightning arrester body, the thyristor valve and related components are integrally mounted, so that the structural strength of the integrated structure of the lightning arrester is greatly improved, the mechanical property and the shock strength of the controllable lightning arrester are improved, and the controllable lightning arrester is ensured to meet the engineering requirements of safety, stability and long-term operation.
Description
technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a thyristor valve-type controllable lightning arrester bracket, an integrated structure and an anti-seismic verification method. Background technique [0002] In the UHV transmission system, the saturation characteristic of the air gap operation impulse discharge voltage is more significant, and the deep reduction of the operating overvoltage level plays a vital role in reducing the line air gap. When the operating overvoltage drops from 1.7pu to 1.6pu, the air gap of the transmission line is reduced by 0.6m on average. In addition, the operating overvoltage level also has a certain impact on the manufacturing difficulty of power transmission and transformation equipment, so it is necessary to deeply reduce the operating overvoltage multiple. [0003] At present, there are mainly two solutions to reduce the operating overvoltage: [0004] 1) Metal oxide arresters an...
