基于皮尔逊相关系数法的水树枝与超低频介损的相关性研究

Gaoya dianqi, 2014
水树枝是交联电缆的主要缺陷,相关研究表明,超低频介质损耗因数与交联电缆水树劣化状态具有较强相关性。笔者通过使用皮尔逊相关系数法,对国际电气电子工程师协会IEEE P4002.9/D9—2010推荐的超低频电压下介损平均值、介损变化率与介损随时间的稳定性3个评价指标,与交联电缆绝缘内部水树枝的密度、长度进行了相关性分析,研究结果对于采用上述指标评估水树枝的生长特性具有较好的理论价值与指导作用。

运行与检修问答

Gaoya dianqi, 1990
【问】测多油断路器的介质损耗因数tgδ应注意什么? 【答】对多油断路器作介质损耗因数tgδ值测试的主要目的是判断其套管是否有严重受潮的现象,电容式套管远较纯瓷套管容易受潮,受了潮也较难处理,最重要的是其发展下去会导致严重的后果。但电容式套管本身远没有多油断路器内某些其它绝缘件那样容易受潮。因此,测试时要注意二点:一是要在断路器分闸状态下进行测试,以免掩盖问题的暴露 ...
