摘　　要：城市轨道交通车辆段出入口处,车辆受电弓通过接触网四跨电分段常出现拉弧现象,通过测试解析阐述其产生的原因及危害性,提出在停车场及车辆段出入口处接触网电分段采用的设置方式及与单向导通配置的绝缘轨缝相互位置配合设置要求,阐明电分段及单导拉弧现象和解决方法。The phenomena of arcing can often be seen during the pantograph of vehicle passing through the catenary electric-sectioning at the entrance or exit of a rolling stock depot of urban rail transit. In this paper, the reason and the danger of the phenomena are explained by means of testing analysis. Further, the paper proposes the method of how to set up the catenary electric-sectioning at the parking lot as well as at the entrance and exit of a rolling stock depot, also proposes how to coordinate its location with the location of insulated rail joint gap of unilateral conducting device, illustrating the arcing phenomena at electric sectioning and unilateral conducting device, and giving the solutions.
