当今我国的科技发展十分迅速,在当前的广播行业的发展中,10千瓦DAM数字发射机在数字发射工作中的应用是非常广泛的,10千瓦DAM数字发射机在工作中也会出现相应的故障,其发射机频烧功放管故障是最为明显的故障。在工作人员工作期间,对于此类故障进行了深度的研究并进行反复测量,引起其工作故障的主要原因就是功放板不够干净,以至于造成电路不顺畅。
Nowadays, our country’s science and technology development is very rapid. In the current development of the broadcasting industry, the application of 10 kilowatts DAM digital transmitters in digital transmitting work is very extensive. The 10 kilowatts DAM digital transmitters also have corresponding troubles at work , Its transmitter frequency firing amplifier tube failure is the most obvious failure. During the work of staff, conducted a deep study of such failures and repeated measurements, the main cause of their work failure is that the power amplifier board is not clean enough, resulting in the circuit is not smooth.
