摘要
探讨了定压式公共广播系统传输线路的一些问题。包括如何计算传输线路的导体截面积,允许线路衰耗多少比较适宜,怎样降低线路衰耗等,并对制定公共广播标准时有关传输线路的要求提出了一些建议。
Some problems of the power transmission circuit in the public address system are discussed. How to calculate the conduct section area of the transmission circuit, how to determine the appropriate circuit loss value and how to reduce the circuit loss are discussed. Finally, some suggestions on the transmission circuit in public address system are given.
