摘　　要：我台信息广播所采用的DX-200中波发射机运行中多次出现了变压器保险熔断、硅管击穿和温度过高等故障,经研究为信号干扰所致。经过对发射机进行技术改造后系统运行良好,电源整流输出稳定,较好的解决了电源谐波和高频信号相互干扰问题。The DX-200 medium wave transmitter used in information broadcasting in our station has many faults such as transformer fuse,silicon tube breakdown and high temperature,which are caused by signal interference.After the technical transformation of the transmitter,the system runs well,the rectifier output of the power supply is stable,and the problem of power harmonic and high frequency signal interference is well solved.
