Research on Snow Melting and Deicing Device of Power Substation Equipment

Transmission lines as the most important part of the entire power system, due to long-term exposure to the air, it is easy to be affected by various external factors in the daily operation process, and may appear cross-area blackouts, personnel electrocution accidents and other problems. Snow and ice cover has been an important destructive factor affecting the safe operation of substation equipment and transmission lines, and accidents caused by snow and ice cover are common. Ice cover overload will lead to equipment deformation, wire fracture, easy to cause the operating mechanism jammed incapacitating normal action, but also easy to cause the outer insulation ice cover flashover discharge, discharge to ground, burst accident. However, the current deicing methods are difficult to meet the requirements of high efficiency and economy at the same time, and there is a lack of a high-efficiency, low-energy, low-cost and reliable deicing technology. Therefore, this paper proposes a hot air ice melting device for substation equipment.
