Abstract

The present invention proposes a remote snow removal method for UHV equipment based on a hot air snow removal device, which includes: determining the unit length of snow melting of the snow removal device, and determining the width of the air outlet of the hot air snow removal device according to the unit length of snow melting; selecting the insulating part of the snow removal device The middle position is used as the starting position of snow melting, and the hot air snow removal device is turned on to melt snow. After the snow melting at the starting position is completed, the snow is melted at the low-voltage end of the insulating part of the snow removal equipment, and then the snow is melted at the high-voltage end; when the snow accumulation on the snow removal equipment is When the snow melts and there is no dripping water on the surface, turn off the hot air snow removal device to complete the snow removal. By selecting 15%-20% of the dry arc distance of the snow removal equipment as the unit length of snow melting, and choosing the hot air snow removal device to remove snow, the efficiency and effect of snow melting are improved. Effective snow removal can effectively prevent snowmelt flashover of UHV insulation equipment and ensure the safe and stable operation of the equipment.

Description

technical field [0001] The invention relates to the technical field of remote snow removal of high voltage equipment, in particular to a method for remote snow removal of UHV equipment based on a hot air snow removal device. Background technique [0002] Under snow-covered conditions, the electrical performance of the wall bushing will drop sharply, causing partial discharge, and in severe cases, flashover, causing power outages, and seriously affecting the safe and reliable operation of electrical equipment and lines. There have been many insulation flashover and breakdown accidents at home and abroad when ice and snow are covered under cold climate conditions, causing great harm and economic losses, which has attracted great attention from power operation departments and scholars. [0003] The pollution level of wall-piercing bushings in my country's industrial concentrated areas reaches its peak in winter with little rain. Snowfall makes a lot of snow on the external insu...
