摘要
研究变压器的在线监测是一项重要的工作,可及时发现变压器的异常状态并进行故障诊断,在减少人力、财力的消耗的同时,又有效保障了变压器的安全可靠运行.研究了油中气体产生的原理和变压器油的取样过程、脱气过程,基于三比值法分析了变压器不同运行状态的油色谱.研究表明,采用三比值法可以有效诊断出变压器故障类型.
Abstract
It is an important work to study the online monitoring of the transformer,timely find the abnormal state of the transformer and make fault diagnosis,and reduce the consumption of human and financial resources,but also effectively guarantee the safe and reliable operation of the transformer.The paper studies the principle of gas pro-duction in oil,the sampling process and degassing process of transformer oil,and analyzes the oil chromatography of different operating states based on three-ratio method.The study shows that the transformer fault type can be effec-tively diagnosed by the three-ratio method.
