摘要:
在地铁场段基地附近的燃气管道上发现强烈干扰的杂散电流。经过反复的现场试验和监测数据分析对比，找出基地出入段线单向导通装置的设计缺陷。根据泄漏电流路径和出入段线钢轨绝缘节的特点，对原系统设备进行硬件改造和软件升级，实现基地与正线钢轨回流双向隔离及导通控制，以隔离杂散电流泄漏路径，将泄漏电流控制在行业标准范围之内。
Abstracts:
The intense interference of stray current is detected on the gas pipelines near a metro train depot. After repeated site tests and monitoring data analysis, the design defects of the unidirectional conduction device for depot entrance/exit lines are identified. According to the characteristics of the leakage current path and the rail insulation joints on entrance/exit lines, the hardware reform and software upgrade for the original system equipment are carried out, in order to realize the two\|way isolation and conduction control between the main line and the depot, so as to control the leakage current path within the scope of industry standards.
