Study on the Engineering Simulation of the Electric Hot Air De-icing Device of the Substation Equipment

摘要

In this paper, heat characteristics, energy conversion efficiency and energy transmission distance of electric hot air de-icing device are researched. Thermal energy conversion formula of jet bushing of hot air device is obtained. Finite element analysis software is used to establish the computing model of hot air de-icing device such as bushing shell, switches and disconnecting link. Take the bushing shell for 500kv transformer for example, de-icing performance is simulated, and de-icing time, energy consumption and energy utilization efficiency are analyzed in this paper. Feasibility and effectiveness of the electric hot air de-icing device is validated too.
