监测器串接于金属氧化物避雷器接地端，用于记录避雷器的动作次数以及泄漏电流。标准JB/T 10492—2025和GB/T 24845—2018对监测器在8/20 μs波形下的动作电流做了规定，而对其他冲击电流波形没有做出要求。在实际系统运行中，流过避雷器的电流波形并非都为标准8/20 μs雷电流波形，导致可能存在避雷器监测器不动作情况。文中针对一起换流站极母线直流避雷器监测器不动作的故障案例，逐项开展试验工作，分析监测器不动作原因。试验结果表明：电流波形越长，波头越缓，避雷器监...

为了准确计算GIS的温升,探究了载流导体邻近与趋肤效应及电流频率对三相共箱式GIS温升的影响。将弹簧触指和梅花触指均简化为圆环体来模拟电接触。采用三维多物理场耦合的方法,计算并对比了考虑与不考虑载流导体邻近与趋肤效应时的GIS的欧姆损耗和温度分布,比较了不同频率对GIS温升的影响。搭建温升试验平台验证了仿真结果的正确性。结果表明,三相共箱式GIS载流导体的邻近与趋肤效应所产生的的附加损耗较大,其影响不可忽略;相比于不考虑邻近与趋肤效应的计算结果,考虑载流导体邻近与趋肤效应下的...
