摘　　要：以山东省济宁市广播电视传输保障中心的防雷工程技术选型实践为例,深入剖析中波发射台站弱电子信息设备遭受雷击导致损坏的原因,提出一种基于感应消雷技术的并联浪涌保护器(Surge Protection Device,SPD)模式升级方案,通过应用实践检验得出结论,该技术可有效消除由雷击引起中波发射台地电势叠加造成电源电压异常的影响,进而为中波发射台站的弱电子信息设备提供充分保护。This article takes the lightning protection engineering technology selection practice of radio and television transmission guarantee center of Jining city,Shandong province as an example,and deeply analyzes the causes of damage to weak electronic information equipment such as monitoring equipment in medium wave transmitting stations caused by lightning strikes.A parallel Surge Protection Device(SPD)mode upgrade scheme based on inductive lightning elimination technology measures is proposed.Through application practice,it is known that this technology can effectively eliminate the impact of abnormal power supply voltage caused by lightning strikes on the ground potential superposition of medium wave transmitting stations,thereby providing sufficient protection for weak electronic information equipment in medium wave transmitting stations.
