Development History And Future Prospects Of Electric Locomotives

Electric locomotive is a kind of traction equipment for rail vehicle transportation. The power is to use traction motor to drive the wheels to rotate, and to make the locomotive run on the track by means of the friction between the wheel and the rail surface. According to the structure classification, there are overhead electric locomotive and battery electric locomotive. Narrow gauge industrial and mining electric locomotive and its supporting electric control system are the leading products in the traction electrical equipment industry.

Since Germany's Siemens company made a 4.5kW mine trolley electric locomotive in the world in 1882, it has a history of 120 years. It also has about 50 years of production development history in China. During this period, more than 50 varieties and specifications of two series of wire-type electric locomotives and battery locomotives have been developed and mass-produced. The products are distributed throughout the country's coal mines, metallurgical mines, railway and highway tunnels, and municipal engineering construction sites.

Electric locomotives have played a huge role in the construction and development of China's mining industry. However, for many years, due to the low investment in product technology development by affiliated companies of the traction electrical equipment branch, most of the products basically remained at the level of the 70s to 80s. At the same time, emerging private enterprises also occupy part of the market share. With China's entry into the WTO, foreign companies are also targeting the Chinese market, making market competition more intense.

China's electric locomotive lacks a branded product with independent intellectual property rights, which affects the status of Chinese electric locomotive sanitary electric locomotive in the world; most Chinese electric locomotive companies lack scientific and strict management in production and produce due to severe environmental pollution The high cost leads to the corresponding increase in the price of electric locomotives, which also seriously affects the economic benefits of enterprises.

Therefore, in order to win a certain market share in the fierce domestic market competition and expand to foreign markets, we must carry out technological innovation and improve the technical content of our products. The past 20 years are the era of rapid development of power electronics technology, and the era of rapid development of electric locomotive technology.

From the perspective of the entire industry of electric locomotives, the market space is still large, so the price of electric locomotives can be adjusted accordingly. Although the electric locomotive industry is already a "sunset industry" in Europe and the United States, it is still a "sunrise industry" in China and there will be great development. The financial tsunami in the United States has an impact on the Chinese ceramics industry, but it is not as large as it is imagined and not so terrible. China is fully capable of going through this economic disaster easily. As the development environment of China's electric vehicle industry further improves, the industry as a whole will further improve.
