摘要
伴随着城市轨道交通直流牵引系统的建立,钢轨电位的理论研究、现场监测和防护问题就一直备受关注,现在国际上对钢轨电位的研究较为重视,每年在美国都会举行一个针对城市轨道交通钢轨电位研究的学术会议,发达国家对此方面的研究已经取得了很大的收获,并且很多研究成果已经得以接纳与采用。文章采用TRIZ发明方法,对怎样控制钢轨电位进行了策略研究,并对得出的几种方法进行了经济技术比较,详细分析了控制钢轨电位对杂散电流腐蚀地下金属管网的原理,并提出合理的调整方案。
With the establishment of the DC traction system of urban rail transit,much attention has been paid to the theoretical research,on-site monitoring and protection of rail potential.Now more attention has been paid to the study of rail potential in the world.Every year in the United States,an academic conference on the study of rail potential of urban rail transit is held in the United States,and great achievements have been made in developed countries in this field.And many research results have been accepted and adopted.By using the method invented by TRIZ,this paper studies how to control the rail potential,makes an economic and technical comparison of several methods,analyzes in detail the principle of controlling the rail potential to corrode the underground metal pipe network by stray current,and puts forward a reasonable adjustment scheme.
