一起220kV变压器油中氢气问题分析和处理

Analysis and Treatment of Hydrogen Problem of a 220kV Transformer

本文中作者以一起220kV变压器运行时油中氢气增长的案例为例,通过油色谱分析、局部放电试验、超声定位等手段,结合变压器的结构,对故障的原因进行了排查分析,最终确定了故障的位置并进行了处理。

In this paper,taking a case of hydrogen exceeding the standard in oil during the operation of 220kV transformer as an example,through DGA,partial discharge test,ultrasonic positioning,combined with the structure of the transformer,the causes of the fault are investigated and analyzed.The location of the fault is determined and dealt with.
