几年来,我国采用减速顶进行现代化改造的铁路编组站迅速增加,其中比较普遍采用的是点连式减速顶调速系统(以下简称点连式调速系统),然而至今对点连式调速系统的设备允许精度和减速器有效控制距离研究较少,致使整个调速系统技术标准不统一,有的为争取车场位能而减少改坡工程量,盲目照搬点式调速系统的200米打靶距离,结果是降低了点连式调速系统的较高连挂率。
Over the past few years, the railway marshalling yard with the modernization of deceleration domes has been rapidly increasing in China. The most commonly used is the point-connected decelerating roof speed control system (hereinafter referred to as point-by-point speed control system). However, System allows the accuracy of the device and reducer to effectively control the distance less studied, resulting in the entire speed control system is not uniform technical standards, and some for reducing the amount of parking spaces can reduce the amount of engineering, blind copy point-type speed control system 200 meters target Distance, the result is to reduce the point connected speed control system with a higher rate of hanging.
