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.
