有线电视系统信号传输的关键器件——放大器,由于工作时间长,所处环境恶劣,尤其在雷雨季节,潮湿、雷电等诸多因素,常常造成放大器大量损坏,给有线台造成经济损失以及给用户造成不良影响,因此放大器维修工作非常重要。那么怎样快速判断及维修放大器呢?笔者将从事这项工作几年的心得介绍给大家。
Due to the long working hours and the harsh environment, the key components of signal transmission in CATV systems, especially in the thunderstorm season, humidity and thunder and lightning, often cause a large number of amplifier damage, causing economic losses to the cable station and causing the user Adverse effects, so amplifier repair work is very important. So how to quickly determine and repair the amplifier? I will be engaged in this work a few years experience introduced to everyone.
