Dianci bileiqi氧化锌避雷器是现代配电线路防雷中的重要一环，但目前对于线路所使用避雷器的选取仍以单重雷击下的数据作为标准。而在自然界中，多重雷击的比例超过40%，短暂时间内的冲击放电对避雷器的耐雷水平提出了更高的要求。因此，本文通过实验的方式，研究了一种42mm氧化锌电阻片在雷击间隔10ms的4/10μs雷电流作用下，分别受到单重、二重以及三重雷击时的电气性能（残压、参考电压）变化，得到该电阻片对于单、二、三重雷击的耐受电流极限分别为120kA、112kA与83kA，所对应雷击总能量分别为28.5kJ、36 ...

Gaoya dianqi风机一旦遭受雷击，机组内部会产生强烈的电磁干扰，影响风机正常运行。为研究雷电击中海上风电机组机舱部位时对风机电子设备造成的电磁影响，文中搭建了基于有限元的海上风机机舱、塔筒及接地体模型，进行海上风机机舱遭受雷击时电磁暂态分布模拟实验，并提出相应的雷电防护措施。仿真结果显示，雷电击中机舱时塔筒顶部的磁感应强度最大，高达3.24×10-4 T，沿塔筒壁向四周逐渐衰减；磁感应强度随接地体所处环境中海水深度的增大而增大；对比风机在海洋环境下首次雷击和二次雷电回击下的电磁场分布 ...
