线路主保护复用数字通道传输设备的供电整改

Power Supply Rectification of Multiplex Digital Channels Transfers Device for the Line Main Protection

通信电源的接入应严格遵循有关规定。讨论了线路保护复用数字通道的现状和通信电源的交叉供电问题,以南京地区三汊湾变电站为例,介绍了对4条线路数字通道的检查和将两组通信设备分别接入不同电信电源的整改措施,该措施现场可操作性强,效果良好。

It has to stick strictly to the relevant regulation for the integration of communication power supply.The current situation of multiplexed digital channels and cross-supply issue of communication power supply for the line main protection are discussed.Taken Sanchawan substation in Nanjing for an example,the examination of 4-line digital channel and rectification measures for two sets of communication device separately supplied by different communication power supply are introduced.The measures have highly operability on site and achieve good effects.
