摘要
本文针对电力企业常用的离相封闭母线常见故障做了简介,对较为多见的绝缘下降事故做了较为详细的分析。探讨问题的根源,即国内过多的关注母线的固体绝缘性能,而忽视了空气的绝缘性能。本文对如何解决离相封闭母线绝缘下降问题提出了自己的见解。以供大家参考。
This article introduces the common faults of out-of-phase closed buses commonly used in power companies,and analyzes the more common insulation drop accidents.Explore the source of the problem.That is,too much attention is paid to the solid insulation performance of the bus in China,while neglecting the insulation performance of the air.And put forward my own views on how to solve the problem of the insulation degradation of the closed phase bus.For your reference.
