结合典型案例,分析了变压器油中单一H2异常的原因,认为单一H2异常不一定表明变压器存在缺陷,应结合红外、铁芯电流、带电局部放电及例行停电试验等测试结果进行综合判断。非故障原因引起变压器油中单一H2异常的原因主要是水分的电解、铁的氧化反应和不锈钢的催化反应。
結閤典型案例,分析瞭變壓器油中單一H2異常的原因,認為單一H2異常不一定錶明變壓器存在缺陷,應結閤紅外、鐵芯電流、帶電跼部放電及例行停電試驗等測試結果進行綜閤判斷。非故障原因引起變壓器油中單一H2異常的原因主要是水分的電解、鐵的氧化反應和不鏽鋼的催化反應。

By combining typical cases, the paper analyzes abnormal H 2 in insulating oil of transformer. It is believed that the single H2 abnormity does not necessarily mean that there are transformer defects, and it should be comprehensively judged by results of infrared test, iron core current test, PD test and routine out-age test. The single H2 abnormity not due to faults is caused by water electrolysis, oxidizing reaction of iron and catalytic reaction of stainless steel.
