由郑州铁路局西安科研所完成的铁道部科研计划项目“郑武电气化区段利用V型天窗作业进行安全防护措施的研究”于1993年12月16日通过了铁道部主持的技术鉴定。 京广线是我国铁路运输繁忙干线之一,该线郑州至武昌段实现AT供电方式的电力牵引后,接触网设备的停电维修与运输矛盾十分突出。为了缓解这种矛盾,要求接触网设备的停电维修与运输行车配合,采用V型天窗方式,但
Ministry of Railways under the auspices of the Ministry of Railways on December 16, 1993, the Ministry of Railways presided over the technical appraisal, completed by the Ministry of Railways Research Institute of Zhengzhou Railway Bureau scientific research project “Zhengwu electrification section of the use of V-type sunroof operations for safety and protection measures.” Beijing-Guangzhou line is one of the trunk lines of China’s rail transport, the line from Zhengzhou to Wuchang AT AT power supply to achieve the power traction, catenary equipment power outage repair and transport conflicts are very prominent. In order to alleviate this kind of contradiction, it is required that the power equipment of the catenary network be repaired and transported and be coordinated with the transportation and driving vehicles, and the V-shaped skylight method should be adopted. However,
