摘要
对某电厂1号变压器油中溶解气体在线监测仪的可燃性气体总量及增长速率超报警设定值取油样进行色谱分析,判断变压器存在过热性故障。停电检查,发现高压引线烧断,说明变压器油中溶解气体在线监测仪的有效性、准确性、重要性。
Chromatography is employed to analyze total combustible gas and hyper-alarm setting of growth rate of online monitoring instrument for gases dissvolved in oil of transformer No. l in a power plant through oil samples, and overheat fault of transformers is figured out. It is found after power cut that the HV lead is burnt out, which verifies effectiveness, preciseness and importance of online monitoring instrument for gases dissvolved in oil of transformers.
