摘　　要：天线倒换系统作为主、备发射机与天线、假负载间必不可少的转换装置,其可靠性与经济性事关中波发射台能否实现“高质量、不间断,既经济又安全”的播出。本文详述了我台天线倒换系统各部分的结构及实现方法,该系统耐高频高压且工作可靠直观,为同行提供了一个可行方案。As a necessary conversion in the primary transmitter,standby transmitters,aerial and dummy loads,the reliability and economy of antenna switching systems are related to whether the medium wave transmitter can achieve“high-quality,uninterrupted,economical and safe”broadcasting.This paper introduces the structure and implementation method of each part of our antenna switching system in detail.This system is resistant to high frequency and high voltage,and works reliably and intuitively,which provides a feasible solution for the whole industry.
