摘　　要：换流变油枕油位是其安全运行中的重要参考量。针对一起换流变油位异常缺陷,通过阐述换流变油位监测原理,利用现场检查、红外测温及实际测量与理论计算分析,确认故障原因为油位表浮球连杆异常,导致换流变出现假油位。提出缺陷处理措施,使换流变油位监测恢复正常,并对换流变油位监测装置的设计和选材提出了建议。The oil level of converter transformer oil pillowis an important reference in its safe operation,for a converter oil level abnormality defect,through the elaborationofthe principle of converter transformeroil level monitoring,theon-site inspection,infrared temperature measurement,actual measurement and theoretical calculation analysisare usedto confirm that the fault is caused by abnormal floating ball connecting rod of oil level meter,which leads to false oil level of converter transformer.The defect treatment measures are put forward to restore the oil level monitoring of converter transformer to normal,and suggestions are put forward for the design and material selection of oil level monitoring device of converter transformer.
