What is electrification?

发布时间:2017-07-07 14:32:43  浏览次数:

At present, there are three types of train traction in our country: steam locomotive traction, diesel locomotive traction and electric locomotive traction. Among them, the trains with electric locomotive traction are called electrified railway. Power traction has the characteristics of large horsepower, high speed, low energy consumption and high efficiency. The power traction section obviously improves the transportation capacity and greatly reduces the transportation cost. Meanwhile, locomotive performance and working conditions are better than diesel locomotives. It is the development direction of China's railway traction power in the future.


First, the status of power traction in railway transport and its development


Rail transport occupies an important position in the national economy, which is the main artery of the national economy and one of the three pillar industries of the national economy. The overall goal of railway technology development in our country is to modernize the railway. The key development directions are to speed up and speed up passenger transport, to re-load and speed up cargo transportation, to systematize safety equipment and to modernize traction power. Technical system. The main technical policies of the railway also clearly pointed out that it is necessary to vigorously develop traction technology for electric locomotives and actively increase the proportion of converted turnover assumed by electric traction. Electric locomotives should be used for traction on high-speed railway, coal transportation lanes, busy trunk lines and long-ramps, long tunnels and high-altitude areas. Active development of AC drive technology will gradually complete the conversion from DC drive to AC drive. Actively develop high-speed passenger trains. It can be predicted that the task of electric traction in China's rail transport will be more and more large and the railway electrification will have a rapid development. Besides locomotive railways, electric locomotives are also playing an increasingly important role in the transportation of urban transport (including suburban EMUs, underground EMUs, and terrestrial trains) and transportation within industrial and mining enterprises.

Electric traction Since the first World Expo in Berlin held in May 1879 in Berlin, Germany's Siemens and Halske have exhibited the world's first 300-meter-long electrified railway and it has been more than 100 years old. Early in the development of electric traction, the main use of DC
