摘要

本文针对在220 kV民丰变电站发现的604、616断路器断口电容介损数据异常情况进行了更进一步的试验及数据分析。对电容量变化相对值最大的003号断口电容进行了解体检查及故障查找。并根据以上的试验数据分析提出了疑似存在缺陷的3台断口电容的故障处理建议

制定了检修策略。

Abstract

In this paper

the test and data analysis for the abnormal dielectric loss data of capacitor acrossthe open contacts found in 604

616 circuit breakers at 220 kV Minfeng substations are performed. The ca-pacitor 003 across the open contacts with maximum relative capacitance variation is disassembled and thefault is checked. The suggestion for three capacitors with suspected detects is proposed on the basis ofabove test data and corresponding maintenance strategy is advised.
