摘要

高频电流的趋肤效应使等效导体中电流产生的热损耗增大，为输电线路融冰提供了一种新的技术方法。文中提出了一种基于

振荡放电的高频融冰方法，利用

RLC

串联电路从某一稳态向另一稳态转换时由电容充放电引起电流变化的特性，通过控制电压方波来获得高频的电流。该方法可以有效降低IGBT的开关频率，减少开关损耗。根据功率器件的性能设计了一台融冰电源，仿真实验表明，对长度分别为40 km和35 km的LGJ-400/50导线、LGJ-240/40导线、LGJ-120/25导线和LGJ-70/10导线可获得1 kHz有效融冰电流。

Abstract

The skin effect of high-frequency current increases the heat loss caused by the current in the conductor

which provides a new technical method for

deicing on transmission lines. In this paper

a kind of high frequency deicing method based on

oscillating discharge is proposed. The high frequency current is obtained by controlling the voltage square wave by using the characteristics of current change caused by capacitor charge and discharge when the

RLC

series circuit is converted from one to another steady state. This method can effectively reduce switching frequency of IGBT and reduce switching loss. According to the characteristics of IGBT

a set of deicing power supply is designed. The simulation experiments show that an effective deicing current of 1 kHz can be obtained for LGJ-400/50、LGJ-240/40、LGJ-120/25 and LGJ-70/10 of wire with lengths of 40 km and 35 km.
