Research on the Applicability of Localization of DKZ13 Electric Train Traction System on Beijing Subway Line 5

The DKZ13 electric train traction system of Beijing Subway Line 5 is manufactured by Hitachi of Japan. With the gradual growth of operation years, the maintenance cost is increasing day by day, and there exist the problem of long supply cycle of spare parts, which causes inconvenience to train maintenance. By optimizing the main circuit design, optimizing the selection of key components, using new technology and new process, the localization alternative development of the original vehicle traction system is carried out, and the localization traction system is tested through type test and main line loading test. The test results show that the system meets the vehicle application requirements, the structural design is reasonable, and the electrical performance is improved.
