4、2011 Aspose Pty Ltd.雷电的种类通常有三种:云间闪络(闪电)云地闪络和雷电 电磁感应。另外一种形象的分类是:直击雷、感应雷、球形雷 。云间闪络即是我们常常看到的闪电,云地闪络是闪电击中地 面的一类,而雷电电磁感应则看不到,它是处在放电云团电磁 场范围内的各个导体上,会感生出强大的电流并且随着导体传 播,损坏各种设备。Evaluation only.Evaluation only.

10、造成的危害非常巨大,人类在长期与 雷电较量中,总结了以下一些防雷方法:均压:建筑物和设备使用的等电位连接较多。均压的目的是让各个参考连接点的电位保持一致,避免电动势移动造成人员和财产损失。接闪:多用于建筑物和室外文物,需安装专业接闪器引下线和接地装置。Evaluation only.Evaluation only.
