摘要
Abstract
To understand the insulation property of neutral reactor in 1 000 kV UHV AC transmission project,the power frequency overvoltage was analyzed and the debugging data of the project were use to simulate the potential distribution of the neutral reactor under impulse voltage.Then,an on-site withstand voltage test method of turn insulation of neutral reactor was proposed,the dynamic stability and thermal stability of the neutral reactor in test process were calculated and checked,and the feasibility and applicability of the on-site withstand voltage test of turn insulation were proved theoretically.In addition,the proposed test method was verified in practical application.This test method is expected to be applied to hand over test of neutral reactor.关键词
