摘要

笔者对河南电网1台550 kV变压器套管烧损的典型故障从试验现象、检查情况等方面进行了介绍

通过对故障套管的解体检查和结构分析

指出拉杆式套管拉杆拉力不够是造成这次变压器套管烧损故障的原因

并据此提出了对拉杆式套管进行拉杆拉力检查、加强制造者与使用者间的技术交流等防范措施。

Abstract

In this paper

according to the test phenomenon and field inspection

a typical burned-out failure of 550 kV transformer bushing in Henan Power Grid is introduced.The cause of the burned-out failure of the transformer bushing is found out to be insufficient pull of the draw rod through the disassembled inspection and structure analysis of the failed bushing.Relevant preventive measures such as testing pull force of draw rod and strengthening the technical exchange between manufacturers and users are provided.
