Parameter Optimization of Electric Pulse Deicer for Overhead Ground Wire Based on Finite Element Method

Abstract Because it is difficult to implement short-circuit deicing, overhead ground wire deicing has always been a problem in power grid ice prevention and disaster reduction. In this paper, the working principle of electric pulse device introduced. Then force calculation model established. The validity verified by comparing model-calculated values coil inductance resistance with experimentally measured values. effect turns, multiplier thickness, side length on peak impulse are analyzed. Finally, test short-size carried out artificial climate chamber. results show that increase number turns coil, value decreases gradually, increases but growth rate slows down. With thickness multiplier, almost unchanged near skin depth. gradually until area close coil. shows efficiency 60-turn 90%.
