摘要
某变电站1号主变从2013年8月至2015年3月先后发生3次异常。前2次油中出现了乙炔,且总烃的绝对产气速率大于注意值,运转热备用后发生气体继电器轻瓦斯报警。通过对1号主变3次异常状况的分析,得到该主变轻瓦斯报警的原因,并提出了相应的处理建议,为变压器运行及类似故障处理提供一定的参考价值。
No. 1 transformer in given substation occurred to three anomalies from August 2013 to March 2015. The first two anomalies appeared acetylene in oil, and the absolute generation speeds of total hydrocarbon is greater than the value of the note. Light gas alarm of gas relay took place after running changed to hot spare. Through analyzing of the three anomalies, the reasons for light gas alarm with the transformer are obtained, and the corresponding treatment recommendation are proposed. The results in the paper may provide cer- tain reference value for transformer operation and troubleshooting similar faults.
