摘　　要：为监测MOA的性能,分析了MOA的非线性特性,论证了MOA的受潮和阀片的老化等变化能反映在阻性电流及其3次谐波上,得出阻性电流及其3次谐波峰值的变化可以作为判断MOA性能好坏的指标;并分析了用谐波分析法计算阻性电流的基本原理,采用ICA对MOA作了监测仿真。结果表明,该方法可适用于MOA的监测,判断其电气性能的优劣。In order to monitor the white zinc arrester＇s performance,the nonlinear characteristics of the arrester is analyzed and the situation that the change of the arrester wetting and valve piece ageing can be indicated on the resistive current and its third harmonic is demonstrated and then the index on judging the arrester＇s performance is obtained according to the change of resistive current and its third harmonic peak value.The basic principle of the resistive current calculation is analyzed using the harmonic analysis method and the monitoring and simulation on the arrester are proceeded too using the ICA.The result shows that the method is suitable for the arrester monitoring and its electrical performance judging.
