悬式绝缘子交流耐压试验新方法

摘要

Suspension insulators were widely used in electric power system,insulation performance is directly related to the personal,equipment and power system security.AC withstand voltage test method was applied to handing over test,preventive test,overhaul and defect treatment.At present,single-chip withstand voltage test method and insulator strings withstand voltage test method were widely used,which still existed shortcomings in test efficiency,accuracy,economy and safety.This paper presented a practical,efficient and safe test method.%悬式绝缘子广泛应用于电力系统中,绝缘性能直接关系到人身、设备及电力系统安全.在交接试验、预防性试验、检修、缺陷处理等环节后需要进行交流耐压试验.目前,广泛采用的耐压试验方法有单片耐压试验、成串耐压试验等方式,各试验方案在试验效率、试验精度、经济性、安全性方面存在缺陷,本文提出了一种实用、高效、安全的试验方法.
