Problems solved by technology

The existing problem of this kind of grounding switch is that: the grounding switch conductive rod is long and its own weight is heavy. When the operating mechanism operates the grounding conductive rod, it needs to overcome the gravitational moment of the grounding conductive rod itself, and the required

Abstract

The invention discloses a grounding switch for a high-end straight-way valve hall, and relates to the field of direct current electric transmission and transformation equipment. An upper switch base, a lower switch base, a rotary device and a counter weight device are designed according to the actual conditions of the high-end valve hall. A grounding conductive rod is installed on the upper switch base, a folding arm connected with the grounding conductive rod is installed on the lower switch base, so that the conductive rod is effectively prevented from being deformed, switch misoperation is avoided, and switch operation impact is reduced. The grounding conductive rod is formed by welding a thick tube and a thin tube, self weight is effectively reduced, and handiness and convenience of mechanism operation are achieved, operating force for switch on-off is suitable, the moving process is stable and reliable, and the service life of the grounding switch is prolonged.

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 high-end 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 installed in the valve hall of the converter valve is very important. The grounding switch in the valve hall is an important part...
