The invention discloses an electrified railway overhead line system wire temperature protection method, which comprises the following steps: collecting overhead line system wire current, sunlight intensity, wind speed, wind direction, environment temperature and other environment data, and calculating through an overhead line system wire thermal circuit model to obtain the temperature of the wire; if the temperature of the wire exceeds a protection constant value, protection is started. Foreign matters such as measuring equipment for actually measuring the temperature of the overhead line system wire do not need to be added, and the overhead line system is safer; the wire temperature is calculated by using the wire current and environmental data, and the implementation is simple.
本发明公开了一种电气化铁路接触网导线温度保护方法,采集接触网导线电流和日照强度、风速、风向、环境温度等环境数据,通过接触网导线热路模型计算得到导线的温度;如导线的温度超过保护定值则启动保护。本发明无需增加实测接触网导线温度的测量设备等异物,对接触网系统更安全;用导线电流与环境数据来推算导线温度,实现简单。
