钢轨电位抑制措施研究

Study on Rail Potential Suppression Measures

为了研究抑制钢轨电位过高的方法,保护信号设备和人员的安全,通过分析钢轨电位产生机理,仿真计算牵引供电和回流通道阻抗,提出了敷设贯通地线并与钢轨等电位连接的防护措施。在西北地区某站的改造试验,验证了防护措施的有效性。

In order to study the method of restraining rail potential from being too high and protect the safety of signal equipment and personnel,this paper analyzes the mechanism of rail potential generation,simulates and calculates the impedance of traction power supply and return channel,and puts forward the protective measures of laying links up grounding wire and equipotential connection with rail.The modifi cation test at a station in Northwest China has verifi ed the effectiveness of the protective measures.
