摘要
广播电视发射机开机时容易发生因为操作人员操作失误而产生的烧毁发射机事故。为了解决这个问题,本文根据笔者在发射台一线工作的实际情况,设计出一种安全的主备发射机电源相互锁定的装置,可以避免出现不必要的播出事故。
At present, the accidents of radio and television transmitter system usually occur at boot time, because of operators’ misoperation, transmitter may be burned down when main and backup transmitters are not successfully switched on and antenna is not successfully connected. In order to solve this problem, according to actual situation of the author’s work in front line of transmitting station, this paper designs a safe device to lock power supply of main and backup transmitters, so as to avoid unnecessary broadcasting accidents.
