Dianci bileiqi, 2016 针对检测电涌保护器（SPD）击穿方法的问题,通过对雷电过电压作用下,SPD击穿时周围产生的瞬态电磁场以及电磁感应的理论分析。利用组合波发生器（12、50μs）模拟雷电流发生器,对开关型SPD、限压型SPD分别做冲击试验。试验结果得出:冲击电压为0-5 k V范围时,传感器两端的感应电压随着冲击电压的增大而线性增加;冲击电压相同时,测试开关式压敏电阻的感应电压小于限压型压敏电阻;测试器件相同的情况下,不同表面尺寸的传感器两端的感应电压存在较大差异。探究了利用电磁感应的原理检测SPD的击穿方法 ...

Dianci bileiqi, 2017 快波前冲击过电压对输电线路用盘形悬式瓷绝缘子危害较大,依据标准GB/T20642-2006《高压线路绝缘子空气中冲击击穿试验》,对盘形悬式瓷绝缘子中的空气动力学型瓷绝缘子进行了50%雷电冲击闪络电压和陡波试验,并与钟罩型瓷绝缘子进行了比对研究;研究了瓷绝缘子的形状及大气相对湿度对闪络电压的影响。试验表明:空气动力学型瓷绝缘子50%雷电冲击闪络电压较钟罩型瓷绝缘子低;空气动力学型瓷绝缘子在规定的试验电压下,波前（放电）时间不能满足标准要求;同时,当大气相对湿度较大时,会对瓷绝缘子陡波试验结果产生不利影响。

Dianci bileiqi, 2011 介绍了1 000 kV交流系统用避雷器的电流分布试验方法及研究结果。在操作冲击电流和雷电冲击下多柱并联电阻片的电流分布试验结果表明,冲击电流的波形对电流分布系数的影响不大,但在同一波形下随着冲击电流幅值减小,电流分布系数增大;同时分析了电阻片配组参数,当按照每层每片电阻片的直流2 mA参考电压值和500 A操作冲击残压值之间的偏差同时小于0.5%的原则进行配组,电流分布系数小于10%;不同串联片数的4柱并联电阻片组进行试验,结果表明,随着串联电阻片的数量增加,电流分布系数减小。
