50Hz wave trap lightning arrester bracket structure

Abstract

The invention provides a 50Hz wave trap lightning arrester bracket structure. The wave trap lightning arrester bracket structure comprises a lightning arrester bracket base main body, lightning arrester bracket columns, lightning arrester supporting longitudinal beams and lightning arrester supporting cross beams; the bottom of each lightning arrester bracket column is fixedly connected with the lightning arrester bracket base main body; a conversion top plate is fixedly connected with the top end of each lightning arrester bracket column; the conversion top plates are fixedly connected with the lightning arrester supporting longitudinal beams; the lightning arrester supporting longitudinal beams and the lightning arrester supporting cross beams form a fixed connection structure; the lightning arrester bracket columns and the lightning arrester supporting cross beams form a <pi>-shaped structure. The lateral stiffness of the 50Hz wave trap lightning arrester bracket can be greatly improved, the top displacement absolute amount and top displacement accelerated speed amplification coefficient of the columns can be greatly lowered, and the anti-seismic property of the 50Hz wave trap lightning arrester bracket is reinforced, so that the 50Hz wave trap lightning arrester bracket can well satisfy the safety operation anti-seismic requirements of high-voltage and low-voltage connecting circuits in earthquake high intensity areas.

Description

technical field [0001] The invention relates to the field of structural design of a 50Hz wave trap lightning arrester support structure, in particular to a 50Hz wave trap lightning arrester support structure applied to a ±800kV converter station. Background technique [0002] The installation of the low-voltage equipment in the DC field of the ±800kV converter station requires the civil structure to cooperate with the equipment support, and the electrical equipment is installed on the top of the equipment support. When an earthquake occurs, the equipment support can amplify the displacement and acceleration of the electrical equipment installed on it. Therefore, if the rigidity of the civil structure and related equipment supports used for electrical equipment installation is insufficient, its seismic performance will inevitably be reduced, resulting in poor seismic performance of electrical equipment, which cannot well meet the normal operating conditions of electrical equi...

Problems solved by technology

Therefore, if the rigidity of the civil structure and related equipment supports used for electrical equipment installation is insufficient, its seismic performance will inevitably be reduced, resulting in poor seismic performance of electrical equipment, which cannot well meet the normal operating conditions of electrical equipment, especially It cannot meet the normal operation of electrical equipment when the earthquake intensity is 9 degrees, which seriously affects the normal power transmission

In addition, the installation of low-voltage equipment in the DC field of the ±800kV converter station also requires a certain amount of land resources. Therefore, how to install within the scope of limited land resources to save land resources and ensure the safe operation of various electrical equipment is also an issue. issues that must be considered
