| 摘 要： | 配电网中经常因操作或短路而产生过电压，从而危害电气设备的绝缘安全。以35kV配电母线上的过电压监测数据为例，运用数理统计方法对三相对地操作过电压进行统计计算分析，得出操作过电压幅值倍数的概率密度分布。为设备绝缘配合设计提供有效地依据，具有一定工程意义。 |
| 关 键 词： | 操作过电压 统计分析 绝缘配合 |

| Abstract: | Overvoltage is often generated by the operation or short-circuit fault in distribution network,thereby endangering the insulation safety of electrical equipment.Taking the overvoltage data monitored in 35 kV distribution bus for example,the theoretical analyses and calculations for three-phase switching overvoltage to earth are carried out using mathematical statistics,and the probability density distribution of switching overvoltage amplitude multiple is obtained,which can provide a effective basis for ins... |
