Remote intelligent fault removal device for high-voltage drop switch

Abstract

The invention discloses a remote intelligent fault elimination device for a high-voltage drop switch, which is characterized in that a top bracket and a bottom bracket are fixedly arranged at the upper end and the lower end of a switch body respectively, a winch motor is fixed at the lower end of the bottom bracket, and an insulating lifting rope is wound on a shaft of the winch motor; the fuse is fixed on the fuse base after passing through the through hole in the bottom bracket; a bolt of the fuse base is matched with an insertion hole in the bottom support, the transmission gear is connected with a high-voltage fuse tube through a connecting piece, the upper end of the high-voltage fuse tube is matched with a pressing elastic piece installed on the top support, a pressing electromagnet for attracting the pressing elastic piece is arranged above the pressing elastic piece, and the pressing electromagnet is fixedly installed on the top support. And a signal acquisition control system is additionally arranged on the top bracket. The working efficiency and the power supply reliability can be effectively improved.

Description

technical field [0001] The invention relates to a remote intelligent troubleshooting device for a high-voltage drop switch. Background technique [0002] The drop switch is an indispensable device in high-voltage transmission lines. When the current in the line is too large, the fuse in the drop switch will heat up and blow due to the excessive current, so as to achieve the purpose of protecting the line. When the high-voltage drop switch fails, maintenance personnel need to go to the site to check, the climbing pole is in close contact with the high-voltage equipment, and carries a large amount of maintenance equipment; after arriving at the site, it is necessary to wear various protective props, and the position of the on-site drop switch is different, and the length of the insulating rod is different. It is not easy to grasp in advance; the higher the position of the drop switch, the greater the difficulty of operation, and there are problems such as the inaccuracy of the...

AI Technical Summary

Problems solved by technology

When the high-voltage drop switch breaks down, maintenance personnel need to go to the site to check. The poles are in close contact with high-voltage equipment and carry a lot of maintenance equipment; after arriving at the site, you need to wear various protective props, and the position of the drop switch on site is different, and the length of the insulating rod is different. It is difficult to grasp in advance; the higher the position of the drop switch, the more difficult the operation is, and there are problems such as inaccurate alignment of the insulating rod with the hole of the fuse tube, misalignment of the closing switch with the slot, and inaccurate position of the slot for replacing the fuse tube.

Especially when the manual operation is improper, there will be problems such as arcing, opening and closing sequence errors

This not only threatens the personal safety of the maintenance personnel, but also is inefficient and poses a great potential safety hazard.
