摘要
某35kV变电站出现主变压器轻瓦斯频繁报警现象,通过对该变压器的全面检查,排除了主设备故障,最后确定是由于变压器密封不良而导致外部空气进入。经反复论证、方案优化,对故障变压器处理后其运行正常。本文针对该案例,讨论主变压器轻瓦斯频繁报警时的分析判断思路,为大型设备预警提供经验借鉴。
Frequent alarm of light gas occurred in a 35kV main transformer substation.Through comprehensive inspection of the equipment,the fault of the main equipment was eliminated,and the transformer was confirmed to have poor sealing,resulting in air entering.After repeated demonstration and program optimization,the transformer ran normally after processing.Based on this case,this paper discusses the analysis and judgment while provides experience of large transformer alarm.
