PDM全固态中波广播发射机维护技术探讨

Discussion on Maintenance Technology of PDM All Solid State Medium Wave Broadcasting Transmitter

随着广播电视信号发射范围和要求的不断提高,PDM全固态中波广播发射机使用的范围和类型也在逐步增加。在这样的情况下,除了要注重合理选择发射机类型和规范使用行为以外,还要对PDM全固态中波广播发射机进行常态化、科学化的技术维护,以保证发射机运行的效率和效果。结合PDM全固态中波广播发射机的相关原理以及实际的应用状况,从故障检测技术、故障分析技术和部件及元器件维护技术三个方面对发射机维护的相关技术内容进行讨论分析。

With the continuous improvement of radio and television signal transmission range and requirements,the range and types of PDM all solid state medium wave radio transmitter are gradually increasing.In this case,in addition to paying attention to the reasonable selection of transmitter type and standardizing the use behavior,we should also carry out the normal and scientific technical maintenance for PDM all solid state medium wave broadcast transmitter,so as to ensure the efficiency and effect of transmitter operation.Combined with the theory and application of PDM all solid state medium wave broadcast transmitter,this paper discusses and analyzes the technical content of transmitter maintenance from three aspects of fault detection technology,fault analysis technology and component and component maintenance technology,so as to provide technical method reference for the maintenance of broadcast transmitter.
