摘要
轨道交通中的轨道接缝电阻对轨道电位有着重要的影响，轨道电位过高，会影响轨道交通安全、稳定地运行。为了全面分析轨道电位的分布，设计了一种便携式的轨道电位及接缝电阻的测量装置。测量系统由智能传感器、监测装置和PC机构成，可以测量一个供电区间内的轨道电位和接缝电阻，并且可以对测量数据进行分析、显示和保存。系统携带方便、操作容易、测量精度高，具有广泛的实用性。
High rail potential has great influence on safety and stable operation of mass transit, but the joint gap resistance of the track have an important impact on rail potential. A portable track and potential joint resistance measurement device is designed for a comprehensive analysis of the distribution. The system consists of intelligent sensor, monitoring device and PC, which can measure rail potential and joint gap resistance in a range of power supply. The data of measuring can be anlynized, displayed and saved. It is easy to carry, operate, high - precision measurements, with a wide range of practicality.
