全固态发射机自从90年代后开始逐渐引进到我国各地人民广播电台的使用过程中,这种技术的应用和发展标志着中波发送设备的更新换代,能够有效的替换效率低、指标差、停播率高的电子管中波发射机。随着全固态发射机的广泛应用,在发展过程中逐渐使用了大量的微处理器件和半导体器件,得到了进一步的发展应用。和过去使用的发射机相比较,其增加了很多优点,比如使用年限延长,指标性能要求提高,维护工作量较少等,但是同时这种发射机的器件比较脆弱,耐压较低,抗干扰性能较差,因此在应用于防雷接地过程中,一定要做好全固态发射机的正常工作和维护开展。
All-solid-state transmitters have been gradually introduced to people’s radio stations throughout our country since the 1990s. The application and development of this technology mark the replacement of medium wave transmitting equipment, which can effectively replace the low efficiency, poor indicators, stop Propagation of high frequency tubes in the wave transmitter. With the wide application of all-solid-state transmitters, a large number of microprocessing devices and semiconductor devices have been gradually used in the development process, and have been further developed and applied. Compared with the transmitter used in the past, it has many advantages added, such as prolonging the service life, improving the performance requirements of the indicator, and reducing the workload of the maintenance work. However, at the same time, the device of the transmitter is relatively fragile with low withstand voltage and anti-interference Poor performance, so in the process of lightning protection grounding, we must make all-solid state transmitter normal work and maintenance carried out.
