我国既有铁路干线挖潜扩能的根本途径,是大力提高列车的速度、重量、密度水平。为此,必须采用电力牵引及自动闭塞。本文仅就自动闭塞显示制式问题作一些粗浅的分析。自动闭塞是信号设备,但其制式的选定则涉及运、机、工、电各个方面,是一个综合性的问题,现分述如下。一、闭塞分区长度决定闭塞分区长度的原则是制动距离和追踪间隔时分(即行车密度)的要求,在保证安全制动距离的前提下尽可能缩短闭塞分区长度,以缩短追踪时分,提高平行图能力。
The fundamental way for tapping the potentials of existing railways in our country is to greatly increase the speed, weight and density of trains. To do this, you must use electric traction and automatic blocking. This article only makes some superficial analysis on the auto-blocking display system. Automatic blockade is a signal equipment, but the selection of the system involves all aspects of transport, machinery, industry and electricity. It is a comprehensive issue and is as follows. First, the length of the occlusion partition The principle of blocking the length of the partition is the braking distance and tracking interval time (ie, driving density) requirements, to ensure safe braking distance as much as possible to shorten the occlusion partition length to shorten the tracking time, increase parallel Figure ability.
