Power high-tension porcelain insulator snow-blowing and deicing device

Abstract

The invention discloses a power high-tension porcelain insulator snow-blowing and deicing device, which comprises a fan. An air opening of the fan is connected with an air ejector pipe; a sectional insulated supporting rod is connected above the air ejector pipe; and an anti-rain cover is arranged above the sectional insulating supporting rod. The hot wind from the fan is blown to a porcelain insulator of a high-tension wire so as to melt rain and snow. Therefore, snows, ice columns and ice layers on the surface of the porcelain insulator can be rapidly removed, the security threat of snow, ice rain and other severe weather to power equipment is greatly reduced, and the safe operation of the power equipment in snow, ice rain and other severe weather in winter is guaranteed. Due to the sectional structure, the height of the insulated supporting rod can be flexibly adjusted, so that the device aligns to parts needing snow melting and achieves good snow-melting effect. The anti-rain cover is arranged above the sectional insulated supporting rod, can effectively prevent snow and rain from influencing the device in snow and rain weather, and can save the hot wind, so the snow-melting effect is more obvious.

Description

technical field [0001] The invention relates to a snow-melting device, in particular to a snow-blowing and ice-melting device aimed at snow accumulation on electric high-voltage insulating porcelain bottles. Background technique [0002] Before and after the Spring Festival in 2008, the ice, snow and freezing rain disasters in southern my country caused serious damage to people's production and life, especially the damage to power equipment was devastating, which paralyzed most of the southern power grids, and the restoration and reconstruction work was quite complicated. , the task is quite onerous, causing the country and the people to suffer huge economic losses. This is the most powerful proof of the devastating damage to power equipment caused by ice, snow and freezing rain disasters. The reasons are as follows: [0003] 1. Heavy snow in winter or too long snowing time, the snow accumulated on the surface of the insulating porcelain vase skirt is too thick, and a break...

[0002] Before and after the Spring Festival in 2008, the ice, snow and freezing rain disasters in southern my country caused serious damage to people's production and life, especially the damage to power equipment was devastating, which paralyzed most of the southern power grids, and the restoration and reconstruction work was quite complicated. , the task is quite onerous, causing the country and the people to suffer huge economic losses

[0003] 1. Heavy snow in winter or too long snowing time, the snow accumulated on the surface of the insulating porcelain vase skirt is too thick, and a breakdown short circuit channel is formed on the surface, which is easy to break down the insulation of the high-voltage live conductor to the ground, resulting in accident tripping, large-scale power outages, high-voltage Equipment insulation damage;

[0004] 2. During or after snowing in winter, due to the heating of the current-carrying conductor, heat transfer will be formed between the current-carrying conductor and the insulator that fixes it. When the outdoor ambient temperature is lower than 0°C, the snow on the surface of the porcelain skirt will gradually melt or After partial melting, icicle strings will be formed between the porcelain skirt and the porcelain skirt. When the dielectric strength of the porcelain insulation surface is lower than the breakdown limit, the insulating porcelain bottle will be broken down, causing accidental power outages and serious consequences of equipment damage;

[0007] This method has great disadvantages: there are many insulating porcelain bottles for substation equipment, and each insulating porcelain bottle has many layers of porcelain skirts. This method has a large workload, low efficiency, poor effect, and the speed of snow removal is very slow; 1. When the amount of snowfall is large, it is too late to remove it, and the effect is negligible, and the purpose of fast snow removal and icicle removal cannot be achieved at all.

When using the metal head of an insulating rod to clear snow laterally between the porcelain skirts of insulating porcelain bottles, it is easy to bruise and scratch the porcelain insulating surface, which reduces the insulating strength of the porcelain and brings hidden dangers
