中小驼峰在我国铁路编组站中占有较大比重,但它们的技术设备落后,影响运输生产,急需解决调速系统的现代化问题。哈中心正在探讨三个方案:点连式调速系统、普通全减速顶调速系统、微机可控顶调速系统。三个方案各有其不同的特点和不同的设计方法,在运用实践中不断完善和提高。 Small and medium-sized humps occupy a large proportion in China’s railway marshalling yard, but their technical equipment lags behind and affects transportation and production. Therefore, it is in urgent need of solution to the modernization of speed regulating system. Kazakhstan center is exploring three programs: point-connected speed control system, the general speed control system of top speed, computer controllable speed control system. Each of the three programs has its own characteristics and different design methods, which are constantly being improved and improved in practice.
