摘　　要：本文首先简单介绍了HFC系统集中供电的原理,然后针对HFC系统中分配网常见的供电故障现象,从实践到理论分析了集中供电故障出现的原因,进一步验证同轴电缆及接头等部位对集中供电稳定性的影响,最后总结了导致该类故障的常见因素,并提出相应的处理方法,给相关维护工作提供参考。At first, the paper briefly describes the principle of centralized power supply on the HFC system, and then analyzes the reasons for the centralized power supply failures from practice to theory base on the network power supply failure phenomenon, further validation the stability effect from coaxial cable and connectors. With the purpose to provide a reference to the rdated maintenance work, a number of common factors which probable lead to such failures and the corresponding treatment methods have summarized at last.
