电力线路运行在线监测系统的研制与应用

Development and Application of Online Monitoring System of Power Line Running

铁路配电网的自闭/贯通线路沿铁路线狭长分布,沿线地质气象条件复杂,线路长期暴露在露天中,经受着风、雨、雷、电、污、雾的侵害,是铁路供电系统的最薄弱环节,也是故障发生最多的地方。电力线路运行在线监测系统可以对线路故障进行自动监测并准确定位,大大缩短了人员查找和处理故障的时间,实现缩小故障停电范围、停电时间,提高配网供电能力,增加系统的可靠性,同时节省了人力和物力。

The blocking and continuous power lines of railway distribution network have narrow and long layout and complex geological weather conditions along the railway line. The lines were exposed to natural environment in long term and withstanded the damage of the wind, rain, ray, electricity, sewage and fog so that they are the weakest paint of railway power supply system and also the situation where most failures occur. ＂Online monitoring system of power line running＂ can perform automatic monitoring and accurate locating so as to shorten the staff finding and failure processing time to achieve the small scope and time of power cut for fault. Therefore, this system improved the power supplying ability of distribution network and system reliability and also saved the human and material resources.
