摘　　要：针对双极低端换流变压器分接开关储油柜实际油位和测量油位偏差较大的问题,本文推导了储油柜中浮球、浮杆不同状态与油位之间对应关系,结合现场实际情况开展排查,并给出了详细的理论分析和处理方法。In view of the large deviation between the actual oil level and the measured oil level of the bipolar low-end converter tap switch oil conservator,the paper derives the float and float in the oil conservator.Correspondence between different conditions and oil level,combined with the actual situation of the site,made troubleshooting steps,and gave detailed theoretical analysis and processing procedures.
