主变储油柜缺陷导致的油位异常分析及处理

针对一起主变油位异常缺陷,结合实际油位、显示油位及温度-油位曲线,分析了油位异常的可能原因。计算了指针式油位计摆杆长度,对储油柜容积进行了理论计算分析,结果表明储油柜容积至少应为主变本体油量的10%。指出现有主变存在的缺陷和误差,并提出了处理措施和运维检修建议,为主变验收及维护工作提供了一定的参考。

Analysis and Treatment of Oil Level Abnormity Caused by Defects in Main Transformers

The possible causes of the oil level abnormity were analyzed for the main transformer oil level abnormal defects,combined with the actual oil level,showed oil level and temperature-oil level curve.The length of pointer-type oil level swing-rod was calculated.The capacity of oil conservator was calculated and analyzed,and results show that it should be at least 10% of the body oil volume of main transformers.Defects and errors of existing main transformers were pointed out,and treatment measures and operational maintenance suggestions were put forward,which provides a reference for the main transformer acceptance and maintenance work.
