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 ...

胶浸纸穿墙套管电容芯体悬臂负荷下的绝缘性能研究

Dianci bileiqi
胶浸纸穿墙套管是直流输电工程换流站直流场与阀厅的连接设备，运行条件严酷，需要长期承受机、电、热等多种应力作用，其可靠性对系统安全至关重要。胶浸纸穿墙套管是典型的长悬臂结构，机械应力集中更加突出，因此其重负荷下的绝缘性能研究具有重要意义。国内外现行标准均开展单因素试验考核，与实际多因素工况存在一定差异，尚未见有关直流穿墙套管多因素试验研究的报道。本研究以某典型胶浸纸直流穿墙套管缩比单元电容芯体为研究对象，重点开展重负荷状态下电容芯体的绝缘性能测试。试验数据表明未加悬臂负荷时局部放电合格的电容芯体 ...
