【摘要】：從2014年開始,貴州地球站3 kW高功放B機(jī)的輸出功率出現(xiàn)無規(guī)律波動(dòng)問題,增加了值班員對(duì)故障處理的難度和延長故障處理時(shí)間,給我臺(tái)的安全播出工作帶來很大的安全隱患。通過一段時(shí)間值班員和技術(shù)維護(hù)人員對(duì)功率波動(dòng)現(xiàn)象的觀察和記錄,筆者認(rèn)真對(duì)高功放工作原理進(jìn)行了分析,進(jìn)行了逐級(jí)排除,最終解決了該問題。
[Abstract]:Since 2014, the output power of 3 kW high power amplifier B machine in Guizhou Earth Station has been fluctuated irregularly, which has increased the difficulty of fault handling and prolonged the time of fault handling, and has brought great security hidden trouble to the safe broadcasting work of our station. By observing and recording the phenomenon of power fluctuation during a period of time, the author analyzes the working principle of high power amplifier, eliminates it step by step, and finally solves the problem.
