摘要:
停车场的杂散电流防护一直是地铁工程中的薄弱环节。目前，大部分地铁停车场主要通过设置绝缘轨缝和单向导通装置隔离回流电流来达到降低杂散电流的目的。通过对电气化股道车挡前绝缘轨缝的设置、镟轮库设备打火、正线杂散电流对车场的影响等问题进行分析，提出了相应的优化措施。
Abstracts:
Stray current prevention of metro depot has always been a weak part in metro projects. At present, a lot of depots reduce stray current by setting insulation rail gap and unilateral connecting device to isolate the current. By analyzing problems such as setup of insulation rail gap before buffer stop on electrified track, wheel lathe garage equipment short\|circuit and unilateral\|conducting frame reverse conduction that are existing in current prevention measures, corresponding optimization solutions are proposed.
