Gaoya dianqi, 2015 目前,当GIS断路器单台停电时,由于其两侧相邻的断路器或母线带电运行,该断路器断口并联电容的整体介损tanδ是无法测量的。文中分析了单台断路器停电时断路器断口并联电容整体介损测量的难点,提出了"先接后断"防止高电压、确保安全的方法和采用"形成中性点"消除耦合高压和强电场干扰的技术措施。经试验验证,说明此方法安全可行、实用便捷,具有推广价值。

Dianci bileiqi, 2017 针对雷电电磁波引起电子信息设备损坏造成经济损失的问题,利用理论和实验相结合的方法,建立了天线接收雷电电磁波信号的等效电路模型,对雷电波近场和远场进行辐射耦合。对比分析各线天线和宽带天线耦合雷电波的电压峰峰值及能量,得出雷电流主要分布在低频部分,且随着频率的升高而递减,需特别注意防止低频率雷电波侵入的结论,这对于防雷工程设计具有指导意义。同时提出了宽带天线能更准确拟合雷电电流和雷电电磁脉冲大小以及变化趋势的宽带天线能量法,对今后雷电监测定位和预报系统的改进以及雷电防护的研究具有参考价值。
