摘要
在人工模拟鸟粪闪络现象的基础上 ,对鸟粪闪络机理及闪络条件进行了研究。发现鸟粪闪络主要是空气间隙在瞬间电场畸变情况下的击穿 ,而不是以往认为的沿面闪络。在以往认为的不明原因闪络中 ,有相当一部分实际上是属于鸟粪闪络 。
Based on the successful simulation of flashover caused by bird dropping, the mechanism of this kind of flashoverandtheflashoverconditions arestudied in this paper. It is found that the flashover caused by bird dropping is that the breakdown strength of the electric field of insulator at the air gap is suddenly changed where bird excrement drops, but not theflashoveralong theinsulator surface as previously assumed. Actually, inmanypreviouscasesof unknown reason flashover a considerable number could be attributed to bird droppings. The anti\|flashover method is also discussed.
