摘要

变压器是电力系统中的重要设备之一，变压器承受短路的能力对电网的安全稳定运行有重要的作用。对一起 110 kV 变压器短路承受能力试验不合格进行分析，通过对该变压器短路前后试验数据的对比，结合变压器解体情况，从设计、材质、工艺 3 个方面分析事件发生的原因，并提出针对性的整改措施。

Abstract

Transformer is one of the important equipment in power system． The ability of transformer to withstand short circuit plays an important role in the safe and stable operation of power grid． An unqualified test for short － circuit withstand ability of a 110 kV transformer is analyzed． By comparing the test data before and after the short circuit of transformer，the causes of the accident are analyzed from the aspects of design，material and process combined with the disintegration of the transformer． And the targeted rectification measures are proposed at last．
