摘　　要：具有良好保护性能的氧化锌避雷器在电力系统中被广泛使用,因此研究的重要问题是氧化锌避雷器中电阻片的老化。为了了解氧化锌避雷器电阻片在不同电流与温度条件下的电流和电容的关系,使用MATLAB对氧化锌电阻片进行泄漏电流的仿真分析。仿真分析的结果表明,氧化锌电阻片的V-I曲线和仿真分析所得出不同温度下氧化锌的泄漏电流波形结果一致。The zinc oxide surge arresters with good protection properties are widely used in powersystems. Therefore,the aging of zinc oxide arresters is an important issue that should be studied. In orderto understand the relationship between the current and capacitance of the zinc oxide arrester module un-der different current and temperature conditions,the leakage current of the zinc oxide block was simulat-ed using MATLAB. The simulation analysis results show that the V-I curve and simulation analysis of the zincoxide block show that the leakage current waveform of zinc oxide is consistent at different temperatures.
