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 ...

换流变压器有载分接开关是实现换流变压器调压的核心部件,对保证电力系统电压稳定性起到重要的作用。随着柔性直流输电技术的发展,有载分接开关切换含有谐波分量的负载电流工况日益凸显,经常在多次谐波叠加的复杂工况下进行切换操作,因此切换的负载电流零点会有较大的电流变化率,其显著增加了分接开关的切换负荷,尤其对真空有载分接开关中的真空灭弧室转换电流能力提出了极大挑战。因此,文中针对换流变压器应用的真空有载分接开关的谐波电流切换能力的验证开展了相应的试验技术研究,并通过建立的谐波电流切换试验条件开展了性能验证 ...
