520高铁也来秀恩爱 用的还是“黑科技”(图)

2018-05-21 00:42:55   封面新闻

原标题:高铁为何不能直接加挂车厢?铁路部门:动车组是整体设计

高铁为何不能直接加挂车厢?借着520秀恩爱的契机,“中国铁路”公众号今天用一种很特别的方式,解释了这个困扰很多人的问题。

全文如下:

铁道君想说,《复联3》的盒饭还没有消化,520的玫瑰花已经开始派送。连动车界的钢铁侠们都出双入对了,你还有什么理由不努力……

科普就科普,请勿强行蹭热度。

近日,厦门北至龙岩的D6480次动车组列车在抵达龙岩站后,立即组织清客。与此同时,重联车辆放进股道,在前序车底清客完毕后,关闭车门,进行站内重联作业。为了保证一次到位,于是就Duang……

有好奇的网友在知乎上提问:动车组为什么要重联,而且还车头对车头,为什么不能将车厢直接进行连接呢?

重联的重意味着两个单位的列车或机车,联意味着联系,是统一列控而必须形成的电气、网络、制动系统的联动联调,并不是简单的连接。

藏在“嘴”里的联轴器,起到连接牵引和缓冲的作用,具备电力和数据传输等功能。

两列“复兴号”成功对接

动车组在很多方面都是整体设计考量的,也就是需要将一列动车组看作一个整体,而不是像传统列车那样可以加挂或解编少数几个车厢。运行前进方向的第一列动车组负责操纵。车头参与重联保证了两列车解编后的独立运转能力。总之,成双成对组CP,不能拆散人家啦!

动车组重联,即将日常运行的、具有八节车厢的两列单组动车联挂在一起开行,运力会增加一倍。例如,今年五一小长假期间,中国铁路武汉局集团有限公司对20趟省内动车进行重联运行,每趟动车席位由600余个增加至1200余个,是不是很厉害呢!

如今,中国高铁网络上运行的所有机车被纳入到一个统一的标准中,不同型号和不同控制系统的高速列车可以统一编组运营,跨越中国不同的地域和气候,发挥出高铁网络的最大效率。

跨越车型的“黑科技”get!

铁道君温馨提示:由于重联动车前列和后列互不相通,因此旅客上车时千万不要走错车厢。
