摘要
中波广播发射机是广播传输的重要设备,其故障诊断和应急处理直接影响广播传输质量。针对中波广播发射机常见的故障类型,如功率下降、谐波失真及噪声增大等进行分析,通过实际案例数据总结各类故障的诊断方法。根据不同故障类型,提出相应的应急处理方案,包括备用设备切换、故障模块替换及参数优化调整等操作,旨在有效降低故障对广播传输的影响。实践应用结果表明,提出的诊断方法和应急方案在提升中波广播发射机稳定性、降低故障率方面具有参考价值。
Medium wave broadcasting transmitter is an important equipment of broadcasting transmission,and its fault diagnosis and emergency treatment directly affect the quality of broadcasting transmission.This paper analyzes the common fault types of mediumwave broadcasting transmitter,such as power drop,harmonic distortion and noise increase,and summarizes the diagnosis methods of various faults through the actual case data.According to different fault types,the corresponding emergency treatment plan is put forward,including standby equipment switching,fault module replacement,parameter optimization and adjustment,etc.,which can effectively reduce the impact of fault on broadcast transmission.The results show that the diagnostic method and emergency scheme can improve the stability of the medium wave broadcasting transmitter and reduce the failure rate.
