输电线路雷击事故的发展过程及主要防雷措施和措施<br>架空输电线路雷电事故的发展过程及相应的防护措施如图2-1所示。<br>线路防雷的目的是降低雷击跳闸率，因此线路防雷的原理是试图防止上述发展过程中的任何环节的实现，以避免雷电造成的长期停电。 。可以看出，线路防雷的原理是：防止雷电导体，防止雷电引起的绝缘闪络，防止雷击后工频短路电弧，防止电源的线路中断。

输电线路雷击事故的发展过程和防雷的主要原则和措施<br>架空输电线路上雷电事故的发展过程和相应的防护措施可以用图2-1来说明。<br>线路避雷的目的是降低雷电跳出速率，因此线路避雷原理是尽量防止上述开发过程中任何环节的实现，避免因雷电而长期停电。可见，线路避雷原理是：防止雷电导体，防止雷电引起的绝缘闪存，防止电波短路弧线在雷电闪过后，防止线路中断供电。

Development process of transmission line lightning accident and main principles and measures of lightning protectionThe development process of lightning accidents on overhead transmission lines and the corresponding protective measures can be illustrated with Figure 2-1.The purpose of line lightning protection is to reduce the lightning trip out rate, so the principle of line lightning protection is to try to prevent the realization of any link in the above development process, so as to avoid long-term power failure caused by lightning. It can be seen that the principle of line lightning protection is: to prevent lightning conductor, to prevent insulation flashover caused by lightning, to prevent power frequency short-circuit arc after lightning flashover, to prevent line interruption of power supply.<br>
