Interpretation of Rail Transit Traction Electric-driving System and Its Combined Test Standard

Combined with the formulation and release of TB/T 3357-2015 "Traction electric-driving system for locomotives and EMU" and the revision background of the Track Jacket upcoming new edition of GB/T 25117 "Railway applications-rolling stock-combined test method for traction system", the design of traction electric drive system for railway applications and the application scope of its combined test and purpose, main contents, relationship between this standard and other standards, and future development direction of the standard were described.This paper focused on the interpretation of 11 items covered by the standard key points and key technical Patient Lift Slings and Accessories indicators, and a series of quantitative technical indicators was put forward to provide guidance for the implementation of the standard, which would promote the development of design and test process of key equipment of railway applications towards a more standardized direction.
