接触网覆冰和风舞在线监测系统研究及应用

Research and Application of OCS Icing and Wind Dancing Online Monitoring System

针对电气化铁路接触网覆冰和风舞带来的危害,研发基于称重法和光纤传感器法的接触网导线覆冰和风舞在线监测系统。该系统可实时采集导线拉力、环境温度和湿度、风速和风向、导线的振动等信息,并依据导线、绝缘子参数及由专家分析系统建立的导线覆冰及舞动模型计算接触网覆冰和风舞实时状态,及时给出预警信息,保证电气化铁路安全可靠运行。

In view of the disasters caused by icing on and wind dancing of OCS wires of electrified railway,an online monitoring system based on weighing method and optical fiber vibration sensor was developed.Through collecting the information of wire tension,ambient temperature and humidity,wind speed and direction,wire vibration in real time,one expert analysis system could calculate the real-time icing and wind dancing state based on the conductor and insulator parameters with the conductor icing and galloping model.It could provide the warning information in time to ensure the safe and reliable operation of electrified railway.
