Electric arc prevention method for bearing wheel protective cover in rubber-wheel steel-wheel double-track subway

The invention discloses an electric arc prevention method for a bearing wheel protective cover in a rubber-wheel steel-wheel double-track subway, and the electric arc prevention method is characterized in that the stability between a clamp spring elastic piece and the protective cover is increased, so that the clamp spring elastic piece cannot loosen or fall off in the working process, and the risk of electric arc generation caused by the falling of the protective cover is avoided. Electric arcs can be prevented from being generated between the bearing wheel and the power supply circuit in daily work. 本发明公开了一种胶轮钢轮双轨地铁中承载轮防护罩的防电弧方法，所述防电弧方法是通过增加卡簧弹片与防护罩之间的稳固性，使得在工作过程中，卡簧弹片不会松动或掉落，从而避免了因防护罩掉落产生电弧的风险发生。本发明能避免在日常工作中承载轮与供电线路之间产生电弧。
