Description

technical field

[0001] The invention relates to the field of DC power transmission and transformation equipment, in particular to a grounding switch for a DC valve hall. Background technique

[0002] With the continuous and rapid development of my country's economy, power consumption has maintained a high-speed growth. In order to meet the future development of the national economy, the construction of ultra-high voltage and ultra-high voltage direct current transmission will be increased. DC transmission has the advantages of long transmission distance, good regulation performance, low overvoltage level, and small line loss. It is suitable for long-distance high-power transmission, interval grid interconnection peak regulation, and submarine cable transmission.

[0003] As the key equipment of DC transmission, the safety of the equipment in the valve hall where the converter valve is installed is very important. The grounding switch in the valve hall is an important part of...
