Traction electric drive system is an electric drive system that realizes the functions of traction and electric braking of rail transit vehicles and converts electric energy and kinetic energy: It is the core system of rail transit high-end equipment: GB/T 37863 "Rail Transit Traction Electric Drive System" is a guideline for urban rail vehicles, The important basis for the design and manufacture of the traction electric drive system of locomotives and EMUs is different due to different power supply conditions, system composition, and application fields: GB/T 37863 consists of two parts:

--- Part 1: Urban rail vehicles: It specifies the conditions of use, system composition, technical requirements and inspection of the traction electric drive system of urban rail vehicles methods, inspection rules:

--- Part 2: Locomotives, EMUs: It specifies the operating conditions, system composition and technical requirements of the traction electric drive system of locomotives and EMUs: Requirements, inspection methods, inspection rules: Traction electric drive system for rail transit Part 2: Locomotives, EMUs

1 Scope

Part 2 of China's national standard for railway traction electric drive systems, covering locomotives and multiple units. Where Part 1 addresses the metro, this part addresses main line traction, and the differences are substantial enough to need a separate document. The supply is high voltage alternating current from an overhead catenary rather than direct current from a third rail, so the drive begins with a transformer and a line converter that must draw current at near unity power factor without injecting harmonics back into a supply that is shared with the signalling. The power is an order of magnitude greater. The duty is sustained rather than cyclic - a freight locomotive may pull at full power for an hour on a gradient. And the vehicle crosses the boundaries between electrification systems and between countries, which is why multi-system capability is a requirement rather than an option on much modern equipment.

This document specifies the operating conditions, system composition, Technical requirements, inspection methods, inspection rules: This document applies to the traction electric drive system installed on the AC drive locomotive and EMU, and the traction electric drive system of other types of vehicles Can refer to the implementation:
