通过对有线电视电缆网络的集中供电方案进行设计,并对供电电路设计的分配器、放大器、干线网络、电阻以及接地地线等相关的问题进行计算,对分散供电设计的计算和地线对计算结果的影响等问题进行探究,最后采用对比分析的方式探讨了供电设计方案在具体实践中的应用,设计方案能够满足有线电视电缆网络集中供电的需要。
Through the design of the centralized power supply scheme of the cable television cable network and the calculation of the problems related to the distributor, amplifier, trunk network, resistance and grounding grounding of the power supply circuit design, the calculation of the distributed power supply design and the calculation of the ground line The impact of the results and other issues to explore, and finally the use of comparative analysis of power supply design in the practical application of the program to meet the design requirements of cable television cable network centralized power supply.
