摘要/Abstract

摘要： 介绍了内蒙古华电包头发电有限公司利用#1机组大修机会，对C相主变压器箱体焊缝渗漏油带油进行气割和补焊的过程。通过现场带油处理，避免了主变压器放油吊罩处理工作程序繁琐及主变压器返厂处理的高昂费用，同时也缩短了工期。

关键词: 主变压器, 油箱渗漏, 带油处理, 气割, 补焊

Abstract: There was welding seam leakage fault in No.1 unit main transformer Cphase oil reservoir of Inner Mongolia Huadian Baotou Power Generation Corporation Limited. When No.1 unit was overhauled, the gas cutting and repair welding with oil filled for the oil reservoir had been carried out, and the process was introduced in this paper. Because of the field treatment with oil filled, the tedious work of the oil discharging, the cover hanging and others were avoided, and the high cost for returning the main transformer to the manufacturer to repair was eliminated, and the repair period also was shortened.

Key words: main transformer, oil reservoir leakage, treatment with oil filled, gas cutting, repair welding
