电荷在重力作用和气流作用下产生分离,形成带有正负不同极性的电荷区,当云中的电场达到100kV/m以上的时候,有可见性的闪电就会发生,而这种闪电因为电压大,极其容易破坏地面上的高层建筑。发射台的发射塔一般比较较高,并且带有磁场,更容易在雨天受到雷击,本文从高山广播电视发射台的实际情况出发,探讨如何防止高山广播电视发射台被雷击的问题。
The charge separates under the action of gravity and air flow to form a charge region with positive and negative polarities. When the electric field in the cloud reaches more than 100 kV / m, a visible lightning occurs. Because of this Large voltage, extremely easy to destroy high-rise buildings on the ground. Launching towers generally have relatively high launch towers with magnetic fields that are more susceptible to lightning strikes in rainy days. This article starts with the actual situation of launch stations at Alpine Broadcasting and Television broadcasting and discusses how to prevent the launch of Alpine radio and television transmitters from being struck by lightning.
