全固态中波发射机外部联锁功能的实施

Implementation of External Interlocking Function for All Solid State Medium Wave Transmitter

结合贵州八九六台的实际情况,主要介绍了全固态中波发射机外部联锁的构建和实施过程。以外部联锁的原理为主线,该功能主要依靠主备机、主备天线以及假负载切换组合柜来实施运行。基于此,重点介绍了主备机、主备天线以及假负载切换组合柜的原理图。

Combining with the actual situation of 896 stations in Guizhou,this paper mainly introduces the construction and implementation process of external interlock of all solid-state medium wave transmitter.With the principle of external interlocking as the main line,this function mainly relies on the main and backup machine,the main and backup antenna and false load switching cabinet to implement the operation.Based on this,the schematic diagram of main and standby machines,main standby antennas and dummy load switchover cabinets is mainly introduced.
