摘要
随着交直流电气化铁路、高压输电线路的大量兴建,管道不可避免受到临近电气化设施的干扰。排除或者减缓杂散电流的主要途径是选择合适的杂散电流排流设施。国内目前应用的排流设施主要有极性排流器、钳位式排流器以及固态去耦合器。通过对这几种排流设施进行的现场测试与评价,总结出了每种排流方式的优点与局限性,可为今后不同干扰情况下选择合理的排流减缓方式提供依据。同时,结合现场实践,提出了杂散电流减缓的研究方向。
With the surging development of large DC or AC electrical railways and high-voltage transmission lines,pipeline is inevitably subject to the interference from adjacent electrical facilities.The way to eliminate or mitigate stray current is to select an appropriate current drainage facility.The main current drainage facilities applied in China include polarized electric drainage,clamping electric drainage and solid-state decoupling electric drainage.Based on the field tests and evaluations on the above facility,the advantage and limitation of each drainage method are concluded,which can provide reference for selecting a reasonable drainage method in different situations.Meanwhile,the development goal of stray current drainage is brought forward here.
