某高山广播电视发射台站防雷接地改造案例分析

Case Study of Lightning Protection and Grounding Reconstruction of a High Mountain Radio and Television Transmitting Station

发射台站内的设备如遇雷击会出现严重损坏,因此需要对发射台站采取严格的防雷接地保护。对此,主要研究某地区高山广播电视发射台站防雷接地改造案例,通过使用超绝缘屏蔽独立引下接地技术方案,可以实现雷电泄放,避免地网反击对设备造成损害。通过改造,有效地完成对雷击的预防,较好保护当地广播电视发射台站设备的安全。

The equipment in the lightning launch station will be seriously damaged due to electromagnetic induction,so it is necessary to adopt strict lightning protection grounding protection for the launch station.In this regard,this paper mainly studies the case of lightning protection grounding transformation of a mountain radio and television launch station in a certain area.Through the use of super insulation shield independent lead down grounding technology,lightning discharge can be achieved to avoid damage to equipment caused by ground network counterattack.Through the transformation,the lightning strike prevention can be effectively completed,and the safety of the equipment of the local radio and television launching station can be better protected.
