The Analysis of Electric Phase Separation and Common Technical Issues of High-speed Railway System in China

Abstract

The electric railway, as a vital economic transportation artery, offers high efficiency and effectiveness compared to other modes of transportation. The characteristics of efficient transport, comfortable ride and environmental friendliness have effectively driven regional economic construction and industrial economy along the route, which has significantly enhanced cultural and economic exchanges between different regions, becomes the preferred mode of transportation for medium-distance and long-distance travel, and plays an irreplaceable role in China’s current transportation system. Under the increasing demand for passenger flow, the high-speed and high-density tracking operation of trains has become the new normal of high-speed railway operation management. In the background of national science and technology innovation development strategy, how to further shorten the train tracking interval to improve transportation efficiency and further reduce the energy consumption of train operation to improve the energy utilization level of the railway industry is the focus of the current electric railway construction and operation management department. The electric phase separation is a special and intricate part of the traction power supply system in China’s electric railway, and it is an indispensable component. The article describes that some main techniques relating to electrical phase separation are utilized extensively in China’s high-speed railway, by studying the technologies of electric phase separation, a few new methods were given and shared, which will solve the issues of high energy consumption, increased breakdowns, large equipment loss, and the lower speed, to better serve economic and social development and people’s travel.
