智能化变电站中非常规互感器的现场检验方法

On-Site Inspection Method of Unconventional Mutual Inductor in Intelligent Substation

随着智能化变电站的建设,在非常规互感器被大量应用并经过一段时间运行之后,如何对其进行有效的检验,是一个难题。结合上海地区运行情况,对现场检验方法进行了探索,提出用大电流冲击法来实现对非常规互感器的检验,为现场检验人员提供一种新的思路。

With the construction of intelligent substation,unconventional mutual inductors have been put into opera-tion widely.After running for some time,how to inspect these inductors effectively is arising as a tough problem fa-cing the current inspectors.This paper,combined with operation situation in Shanghai,explored the on-site inspec-tion methods,and proposed that high current impulse be used to inspect unconventional mutual inductor.This new inspection method provides a new way of thinking for the field inspectors.
