“复兴号”以350公里时速开出 中国成高铁商业运营速度最高国家

2017-09-21 08:32:05   央广网

央广网北京9月21日消息(记者郭淼)据中国之声《新闻纵横》报道,8点01分G6次“复兴号”列车从南京南站开出,这将是今天零点起全国铁路实施新运行图后,“复兴号”首次以350公里的时速在京沪高铁上运行。这标志着中国成为了世界上高铁商业运营速度最高的国家。

提速前,高铁列车穿行京沪之间需要4小时49分到4小时56分,而达到350公里时速后,“复兴号”动车组从上海到北京的最快运行时间仅需4小时24分左右;从南京到北京更是最快只需要3小时26分。这完全可以做到早饭在上海吃完生煎,午饭就吃上正宗的北京烤鸭。从6月中旬“复兴号”出厂,到正式上线运营,再到全面达速运行,除了稳步提升的速度,“复兴号”的车厢更加舒适,从座椅到卫生间再到饮水处,提升的更是乘坐体验。

今天起,在京沪高铁实现350公里时速运营的“复兴号”动车组一共有7对,分别是从G1到G10次、G13、G14次和G17、G18次。此次调图后票价保持不变,是提速不提价。

在正于美国印第安纳波利斯举行的2017美国铁路工业展览会上,中国高铁成为了热议名词,350公里标准动车组电机模型吸引了大批业内人士驻足参观,这就是复兴号动车组的“心脏”。这一具有完全自主知识产权、达到世界先进水平的中国标准动车组,是怎么展示“中国制造”的魅力的?

在中国铁道科学研究院首席工程师、研究员赵红卫看来,中国高铁时隔6年回归到“350时代”,让中国当仁不让的站到了全球高铁商业运营速度最高舞台上。“目前日本和法国高铁的最高运营时速都是320公里。”

中国铁道研究院机车车辆研究所研究员张波告诉记者,“复兴号”的诞生标志着我国铁路技术装备水平进入一个崭新时代。“我们构建了一个完全自主的动车组产品平台,以前CRH系列虽然进行了很多自主的改进,但基本是在原来的框架下进行。在标动的时候我们重新构建了自己的产品平台,以后的开发就不会受到既有平台的限制。”

“复兴号”被冠以了“中国标准动车组”的称号,而中国标准动车组的“中国”,就意味着高铁从最早的“洋基因”、“混血”、“以我为主”,变成了“纯中国”。中国铁道研究院首席研究员陆阳说“复兴号”对雷电的耐受力明显增强,使用寿命可以达到30年。“过去要耐受170千伏的雷电冲击电压,现在耐受185千伏雷电冲击还没有任何损伤,在耐压上进行了提高。中国不像欧洲,中国雷雨季节比较多,这样更适合中国国情。”
