为实现周总理在四届人大提出的两步宏图,为实现四个现代化,我国的电气化铁路必将迅速发展。据宝成线电力机车运用经验及某些有可能电化或将要电化线路的调查、计算表明:不仅各线之间的牵引定数不统一,且同一线路上不同区间之间、上下行之间牵引定数也不统一。从而使有关技术站增加了改编作业量,对机车的运用也带来了许多不便。在不同的线路条件下,仅有一种SS_I型机车,不能适应实际的需要。对统一牵引定数,取
In order to realize the two-step grand plan proposed by Premier Zhou during the Fourth National People’s Congress, in order to realize the four modernizations, the electrified railway in our country will surely develop rapidly. According to Baocheng electric locomotive experience and the possible use of some electrochemical or electrochemical lines to be investigated, the calculation shows that: not only the number of traction between the lines is not uniform, and different sections on the same line, the number of traction between the up and down Not uniform. As a result, the number of workplaces involved in the technical station has been increased and inconvenience has also been caused to the use of locomotives. Under different circuit conditions, only one type of SS_I locomotive can not meet the actual needs. The unified traction set, take
