摘要
通过红外测温和预防性试验发现罗店变电站的多只110 kV复合套氧化锌避雷器的绝缘性能有所下降,经解体试验和分析,认为原因是密封不良导致环氧筒受潮。指出红外测温能有效发现运行中的复合套氧化锌避雷器的此类缺陷。
It is found that the electrical insulation performance of many 110 kV polymer housed zinc oxide arrester degrades in Luodian Substation after the infrared temperature measurement and preventive tests.Cause analysis is performed after disassembly experiments.The reason is the undesirable sealing leading to epoxy tube affected by dampness.It indicates that the infrared temperature measurement is an effective method to detect this type of defect of the running zinc oxide arrester.
