摘　　要：对城市轨道交通钢轨电位限制器应用中存在的问题进行分析,如频繁通断及闭锁会导致杂散电流泄露增大、运营维护工作量增加等。结合钢轨电位限制器的功能及动作原理,提出引入列车进/出站信号作为保护判据的新型控制方式,以减少钢轨电位限制器的误动作。Existing problems in the application of negative potential monitoring and protection devices in urban rail transit are examined. For example, frequent opening/closing the device caused the increase of stray current leakage and maintenance work load. Based on the functions and principles of the device, the paper puts forward the new control method which takes the entry/exit signal of trains as one of the protection criteria so as to decrease the fauky action of the device.
