干线放大器常见故障的分析与改进

摘要

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 sta-tistics 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 .%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。
