摘要
快速发展的电子技术促进了中波广播发射机的迅速更新与优化,让其在中波电台中的运用越来越多.全固态中波发射机具有较低的能耗,性能稳定可靠且效率更高,合理满足了用户的使用需求。与电子管发射机相比,中波发射机需要更为良好的工作环境,风沙、雷电等因素都会对发射效果造成较大影响,继而导致输出功率降低。基于此,首先分析中波发射机电调网络的设计原理和基本结构,进而探讨影响天调网络运行的因素,为提升天调网络调配质量提供借鉴。此外,为进一步提升全固态中波发射机天调网络运行的可靠性,基于天调网络运行原理提出了相应的改进方法,保证中波广播发射机的有序运行,充分发挥其最大的社会价值与经济价值。
The rapid development of electronic technology promotes the rapid updating and optimization of medium-wave broadcasting transmitter,which makes it more and more widely used in medium-wave radio. All-solid-state mediumwave transmitter has lower energy consumption,stable performance,reliability and higher efficiency,and reasonably meets the user’s needs. Compared with the tube transmitter,the medium wave transmitter needs a better working environment.Wind and sand,lightning and other factors will have a greater impact on the launching effect,which will lead to lower output power. Based on this,this paper first analyses the design principle and basic structure of the tuning network of the wave transmitter,and then discusses the factors affecting the operation of the tuning network,so as to provide a reference for improving the quality of the tuning network. In addition,in order to further enhance the reliability of all-solid-state mediumwave transmitter sky-tuning network operation,based on the principle of sky-tuning network operation,corresponding improvement methods are proposed to ensure the orderly operation of medium-wave broadcasting transmitter,and give full play to its maximum social and economic value.
