The invention belongs to the technical field of metro vehicle power supply construction, and particularly relates to a joint type electric split-phase construction method for an overhead rigid contact network with the speed of 160 km per hour. In order to solve the technical problems that in a 27.5 kV alternating-current power supply mode, out-of-phase electricity is short-circuited, and a contact network is fused, the method comprises the following steps that S100, an electric split-phase inner support suspension device is installed; s200, a busbar is installed; s300, mounting a central anchor knot of a neutral region; s400, erecting a contact line; s500, electric split-phase adjustment is carried out; s600, mounting the breaking and connecting standard; and S700, the geomagnetic induction device is installed. Due to the fact that the rigid catenary anchor section joint is simple in structure and convenient to adjust, the smoothness of a contact line at the electric split-phase position is improved, natural and stable transition of a pantograph at the electric split-phase position is guaranteed, the arcing rate of a catenary is reduced, and the operation speed is greatly increased.
本发明属于地铁车辆供电施工技术领域,具体是一种时速160km架空刚性接触网关节式电分相施工方法。为了避免在27.5kV交流供电制式下,异相电短路并造成熔断接触网,的技术问题,包括以下步骤,S100~电分相内支持悬挂装置安装;S200~汇流排安装;S300~安装中性区中心锚结;S400~接触线架设;S500~电分相调整;S600~断合标安装;S700~地磁感应装置安装。本发明由于刚性接触网锚段关节结构简单,便于调整,提高了电分相处接触线的平顺度,保证了受电弓在电分相处自然平稳过渡,降低了接触网燃弧率,大大提高了运营速度。
