Embodiment Construction

[0024] An embodiment of a grounding switch for a DC valve hall Figure 1~5 As shown: it includes a grounding conductive rod mechanism and a driving device. The grounding conductive rod mechanism includes a grounding conductive rod 6 and a transmission base 2 for installation on the wall 20 of the corresponding valve hall. One end of the grounding conductive rod 6 is used to install the corresponding dynamic The other end of the contact 13 is fixed with a rotating shaft of the conductive rod that is rotatably matched with the transmission base 2. The rotating axis of the rotating shaft of the conductive rod extends along the left and right directions. Through the rotating shaft of the conductive rod, the grounding conductive rod 6 can swing back and forth relative to the wall of the valve hall. The grounding conductive rod mechanism also includes a counterweight structure that is connected to the rotating shaft of the conductive rod through a balance transmission mechanism to ap...

Abstract

The present invention relates to a grounding switch for a direct-current valve hall and a grounding conductive rod mechanism thereof. The grounding conductive rod mechanism comprises a grounding conductive rod which can swing front and back relative to a corresponding valve hall wall surface, and a transmission base mounted on the corresponding valve hall wall surface. The rotating shaft of the conductive rod is fixed on one end of the grounding conductive rod, wherein the rotating axes of the conductive rod extends along the left and right direction and the rotating shaft is rotatablely cooperated with the transmission base. The grounding conductive rod mechanism also comprises a counterweight structure which is transmission connected to the rotating shaft of the conductive rod by a balance transmission mechanism to apply torque for overcoming gravitational torque of the grounding conductive rod. This invention solves the problem that a grounding conductive rod in the prior art cannot be switched on or off stably.

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...
