摘要
由于CATV网络覆盖范围大,线路中的浪涌可远距离传播,加上干线放大器多为户外安装,工作环境恶劣,因而干线放大器损坏的现象比较常见。通过对约100台损坏的干线放大器进行统计,分析发生故障的原因,并对故障进行分类,根据不同类别的故障原因,给出排除故障的方法,针对性地提出改进措施,减少故障发生的几率。
Due to the large range of CATV network coverage,Line surge can propagate long distances,And most amplifiers are installed outdoors,Thus the trunk amplifier damage phenomenon is common. Through statistics on about 100 damaged trunk amplifier,Analysis of the reasons for failure,He gives a different way to resolve the fault. Put forward the improvement measures,reduce the probability of the occurrence of faults.
