本文通过对广播发射台电力系统中外电线路、配电设备在运行时经常出现的故障和存在的缺陷进行了技术分析,提出了改造方案,并把改造的技术方案实施到系统的运行之中。经专家组的评估鉴定和对改造后的系统进行实际观察,发现经过技术改造后的电力系统运行更加安全、稳定,可操作性强,为发射台的安全播出工作提供了有力的保障。
In this paper, technical analysis of the frequent failures and existing defects of foreign transmission lines and power distribution equipment in the broadcasting station power system during operation are put forward. The solutions are proposed and the technical solutions of the transformation are implemented into the operation of the system. After the expert group appraisal and the actual observation of the transformed system, it is found that the power system after the technological transformation is safer, more stable and more maneuverable, which provides a strong guarantee for the safe broadcasting of the launch pad.
