宝鸡水电段成立于1974年7月,随着我国铁路事业的发展,她已走过25年的光辉历程,并逐步发展成为一个集供电、水电于一体的综合段。在纪念建段25周年之际,按照“科技兴段、强基达标”的指导思想,出版这本学术论文专辑,作为献给段庆的一份礼物,应该说是很有意义的。宝鸡水电段所辖线路为通往西南、西北的交通要道,又为第二座欧亚大陆桥的重要组成部分,在路网中占有很重要的地位。宝鸡作为我国第一条电气化铁路(宝鸡—凤州)的起点和电气化铁路人才的摇篮,电气化铁路从这里走向平原,走向干线,并得到迅速发展。一批批电化专业人才从这里脱颖而出,遍及全路。现在,设备由我们来运营管理,我们既感到荣幸、也感到责任、更鼓舞我们努力奋斗。建段25年来,宝鸡水电段广大技术人员,克服了所辖设备种类多(宝天接触网为山区简单悬 Baoji Hydropower Section was established in July 1974, with the development of China’s railway industry, she has gone 25 years of glorious history, and gradually developed into a set of electricity, water and electricity in one of the integrated section. On the occasion of the commemoration of the 25th anniversary of the establishment of a section, publishing this academic dissertation in accordance with the guiding ideology of “rejuvenating the science and technology and meeting the requirements of strong foundation” as a gift for Duan Qing should be said to make sense. The route under the jurisdiction of Baoji Hydropower is an important thoroughfare to the southwest and northwest, and an important part of the second Eurasian Continental Bridge. It occupies a very important position in the road network. As the starting point of China’s first electrified railway (Baoji-Fengzhou) and the cradle of electrified railway talents, Baoji is moving from here to the plains and to the main line and has been developing rapidly. A batch of electrochemical professionals stand out from here, throughout the entire road. Now that the equipment is operated and managed by us, we are both honored and responsible and encourage us to work hard. Over the past 25 years since the establishment of the section, a large number of technicians from Baoji Hydropower Station have overcome many kinds of equipment under their jurisdiction (Baotian catenary is simply hanging in the mountains
