基站供电变压器被雷击的原因及预防

The Reasons on Base Station Power Supplying Transformer Being Struck by Lightning and Its Precautions

根据基站变压器防雷击的实际,分析了铁塔接闪时,基站地网上所产生的地电位升,及其对基站变压器的影响;指出该地电位升是基站变压器被"正反变换"损坏的主要原因;提出了预防基站变压器被雷击损坏的方法;此外对基站内SPD的安装位置也提出了明确的要求。

Based on the prevention of base station transformer from lightning, it analyzes the rise of earth potential on base station earth mat when the iron tower is struck by lightning, and the influence on base station transformer. It points out that the rise of earth potential is the reason of transformer damage. It gives the methods on preventing the damage of transformer from lightning. Final y it also gives the specific requirements on instal ation position of SPD in base station.
