摘要
对IEEE提出的避雷器等效模型进行简化,采用多指数拟合函数拟合避雷器小电流区和中电流区的工作曲线。依照该曲线,分析研究谐波电压、避雷器老化和污秽对避雷器泄漏电流的影响。
In order to fit the curve of arrester working in the lower current field and the middle current field,the modeling of arrester formed in 1992 by IEEE was simplified. According to the fitting curve,the influences of harmonic voltage,the aging condition of arrester and pollution degree on leakage current of arresters were studied.
