F103S全固态10KW调频广播发射机系目前国内较大功率机型,是陕西海纳厂生产,已在我台和其他发射台投入使用。它是由意大利生产的30W激励器,经过二分配器,分成两路,再由四分配器,分成八路,分别推动八个1.2KW功放模块,八个1.2KW功放模块通过两个四合成器,再由二合成器合成为10KW。其中1.2KW功放模块由一级30W推动放大,分成四路推动四个250W放大器,最后合成1.2KW(功率放大器的冗余设计)。此发射结构简单,造价低,得到用户接受。美中不足是技术要求高,现将实际运行中遇到故障几例,列出二例供同行维护中参考。
F103S all-solid-state 10KW FM radio transmitter is currently the more domestic high-power model, is the production plant in Shaanxi Haina, has been launched in Taiwan and other launch pad. It is produced by the Italian 30W exciter, after two divider, divided into two, and then by the four divider, divided into eight, respectively, to promote eight 1.2KW power amplifier module, eight 1.2KW power amplifier module through two four-synthesizer, Then synthesized by the two synthesizer 10KW. Which 1.2KW amplifier module driven by a 30W amplification, divided into four to promote four 250W amplifier, the final synthesis of 1.2KW (power amplifier redundancy design). This launch structure is simple, low cost, user acceptance. The fly in the ointment is the high technical requirements, the actual operation is now encountered a few cases of failure, listed in two cases for reference in the maintenance of counterparts.
