摘要(Abstract):

针对一起220 k V油浸正立式电流互感器绝缘受潮缺陷,开展了基于常规电气试验、频域介电谱测试、油中溶解气体分析、脱气处理前后对比分析以及故障解体检查的综合诊断分析与探讨。结果表明,综合高电压介质损耗、频域介电谱、局部放电以及油色谱分析试验可对电流互感器的绝缘受潮缺陷进行有效诊断。
Based on the conventional electrical test, frequency domain spectroscope test, oil dissolved gas analysis and other means of detection and degassing treatment analysis and fault disintegration inspection, the insulation damp defects with 220 k V oil-immersed vertical current transformer is analyzed. The results show that integrating with high voltage dielectric loss test, frequency domain spectroscope test, partial discharge test and oil chromatography analysis test, the insulation damp defects of current transformers can be effectively diagnosed.
