大秦线开行20kt级重载组合列车系统集成与创新

System Integration and Innovation of Operating 20 kt Combined Heavy-haul Train on Datong—Qinhuangdao Line

大秦线是我国第一条双线重载电气化运煤专线,西起北同蒲线,东至秦皇岛,全长653 km,设计运量为1×108t/a,于1992年12月通车。为满足国民经济发展的要求,须尽快大幅度提高大秦线的运输能力。铁道部依靠自主创新,首次实现了GSM-R技术与Locotrol技术的结合,800 MHz数据电台与Locotrol技术的结合,单套Locotrol系统与SS4机车的结合,以及2台和谐型大功率机车加可控列尾的创新方式,开发了重载配套装备,通过集成创新,使大秦线开行20 kt级重载组合列车获得成功,年运量由2002年的1×108t提高到2007年的3×108t,是原设计能力的3倍。

Datong--Qinhuangdao line, as the first electrified double-track heavy-haul line dedicated to coal transportation in China, extends from Beitongpu line in the west, reaches Qinhuangdao in the east, and opened in Dec. , 1992, totaling 653 km with designed volume of 1 × 10^8 t/a. In order to meet the requirements of national economical development, the transport capacity of the line must be expanded rapidly. Depending on independent innovation, MOR, for the first time in the world, realized the integration between GSM-R and Locotrol, the integration between 800 MHz digital radio and Locotrol, and the integration between a single set of Locotrol and SS4. Meanwhile, it developed auxiliary equipment for heavy-haul transportation through combining 2 Hexie heavy-duty locomotives with controllable train ends. Relying on integration innovation, it succeeded in operating 20 kt-level combined heavy-haul train on Datong--Qinhuangdao line, which triples the annual volume of the line from 1 × 10^8 t in 2002 to 3 × 10^8t in 2007.
