Research on high-energy light spot deicing method for substation insulator

In this paper, the laser deicing technology of substation equipment is systematically studied from the aspects of theoretical analysis, simulation test and so on. Deicing characteristics of CO2 laser on the porcelain pillar insulators are obtained. The heat thawing effect and thermal stress effect of the main components of the substation under the action of laser are studied, and the main installation of the substation is obtained. The heat conduction effect and laser energy consumption per unit area are required. Relationship between the surface temperature of the insulator, exposure time and type of damage is obtained. Design method of high energy laser spot is put forward and experiment is carried out. The results show that the laser can be used for deicing of the transformer, heat thawing effect, thermal stress effect, the balance between melting power and heat conduction efficiency, and deicing quickly and safely without damage to the equipment.
