摘要
全固态中波发射机是目前广播系统普遍使用的主要设备,全固态中波发射机具有极高的稳定性,可以提高工作效率。但同时,因为全固态中波发射机的功放变压器模块由相应的场效应管件来进行构成,其单管的耐压值也要相对地较低,因此面临着单管耐压过低、容易被雷击等问题,所以如果遇到了较强的雷电天气,很容易危及到发射机的正常使用。相关工作人员必须根据雷电天气会为发射器产生危害的主要原因进行分析,探究合适的防雷技术来保证全固态中波发射机可以在雷雨天气中正常工作。
All-solid-state medium-wave transmitters are the main equipment commonly used in broadcasting systems at present.Al-solid-state medium-wave transmitters have extremely high stability and can effectively improve work eficiency.But at the same time,because the power amplifier transformer module of the all-solid-state medium wave transmitter is composed of corresponding field effect tube parts,the withstand voltage value of its single tube is also relatively low,so it faces the problem that the withstand voltage of the single tube is too low and easy to be damaged.Lightning strikes and other problems,so if you encounter strong lightning weather,it is easy to endanger the normal use of the transmitter.It can be seen that the lightning protection work of all-solid-state medium wave transmitters is very important.Relevant staff must be based on lightning weather.The main reasons for the harm of the transmitter are analyzed,and the appropriate lightning protection technology is explored to ensure that the all-solid state medium wave transmitter can work normally in thunderstorm weather.
