By adoption of the +/- 800 kV convertor station direct-current field high-voltage equipment mounting structure provided by the invention,the excellent anti-seismic property of each electrical loop during a high-intensity earthquake can be ensured, the equipment bracket column top displacement acceleration amplification coefficient canmet the requirements of anti-seismic specifications for electric power facilities, and then the normal running requirements of electrical equipment can be met. Through the optimization of the direct-current field layout, the occupied land area can be reduced, and the safe distance can be kept after the electrical equipment is mounted in place.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment installation in a DC field of a ±800kV converter station, in particular to an installation structure for high-voltage equipment in a DC field of a ±800kV converter station. Background technique [0002] In the field of UHV DC transmission in electric power engineering, the requirements for civil structures and equipment supports are very high. The installation of the high-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...

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 high-voltage equipment in the DC field of the ±800kV converter station also requires a certain amount of land resources. Therefore, how to save the land resources occupied by the DC field of the ±800kV converter station to the greatest extent and ensure the safe operation of all electrical equipment , is also a question that must be considered
