Lightning Protection Design for Medium Wave Broadcast Transmission Feeder Line Systems
The working environment of the feeder system of medium wave broadcast transmitting sky is complicated and the lightning protection design task is difficult.This paper analyzes the key factors affecting the lightning protection effect of the antenna feeder,and puts forward the lightning protection strategy from the aspects of device selection,grounding optimization and line protection.In terms of device selection,lightning rod and isolation switch are arranged in key parts.The grounding system uses high-quality materials and adopts multi-point grounding to reduce grounding resistance.At the same time,strengthen the protection of the line itself,improve the insulation and waterproof performance.These measures can effectively protect the safety of the antenna feeder.
