| 摘 要： | 沿染污绝缘表面的交流电弧在每周内强度交变，甚至当电流过零时发生熄灭和重燃。决定交流污闪条件的最重要的因素是交流电弧的恢复条件，而不是以往人们所认为的重燃条件。本文对交流电弧的恢复条件作了理论分析和试验验证，并提出了计算染污绝缘子交流污闪条件的数学模型，理论计算结果和试验结果是相符的。

| Abstract: | The AC arc on pollution surface is alternate in strength in each cycle and even extinguishes and reignnes during the current passing through zero. It is proposed that the most important factor to determine the AC flashover criterion is the recovery condition, but not the reignition condition as proposed by others. The recovers conditions of AC are on pollution surface are theoretically analysed and checked by tests. The mathematical model to calculate the AC flashover criterion of polluted insulators was presented. The calculated results are in agreement with experimental data. |
