摘　　要：为分析10 kV母线绝缘老化的各种故障参数的变化情况,基于电力系统计算机辅助设计(Power system Computer Aided Design,PSCAD),对10 kV封闭母线绝缘老化进行仿真,得到单相和三相母线接地线电流与绝缘电容、绝缘电阻以及介质损耗正切值之间的关系曲线。结果表明:仿真计算与分析为监测10 kV母线绝缘老化情况,有效预防母线绝缘老化引起的故障提供了依据。In order to analyze the variations of parameters for insulation aging fault of 10 kV bus bar, bases on Power system Computer Aided Design（PSCAD）, by simulation for insulation aging of 10 kV closed bus bar, finds out the relation curves among the earth wire current of single-phase and three-phases bus bar with the insulation capacitance, insulation resistance and dielectric loss angular tangent value. The result shows that the simulation calculation and analysis can offer effectively gist for monitoring l0 kV bus bar insulation aging trend, and preventing the fault bringed by bus bar insula- tion aging.
