摘要
目前,数字调制(DAM)中波发射机的稳定性和可靠性比以往发射机有显著提高。然而,发射机工作涉及部件和链路繁多,一个元器件接触不良就可能导致发射机不能正常开机,因此,维护工作仍不可忽视。通过对发射机外部联锁故障红灯又自动恢复正常的故障实例展开分析和处理,以期为业内人士提供一些有益的参考。
At present,the stability and reliability of digital modulated(DAM)medium wave transmitters are significantly improved compared with previous transmitters.However,the transmitter work involves many components and links,so it may not be able to start up properly if a component is not properly contacted.Therefore,the maintenance work still cannot be ignored.In this paper,we analyze and deal with the cases where the red light of the external interlock fault of the transmitter automatically returns to normal,in order to provide some useful references for the industry.
