摘要
研究了固体绝缘表面电荷对不均匀电场直流电晕起始电压、伏安特性的影响。提出了确定最低直流闪络电压的实验方法,并分析沿面闪络过程受表面电荷的影响及其机理,对电气设备绝缘系统设计有实际意义。
The effect of insulator surface charges on DC corona initial voltage and V-I characteristic in non-uniform field is studied. The experiment of determining DC minimum flashover voltage is proposed. The mechanism of surface charges influen -cing the process of flashover is analyzed.
