Release of Technical Specifications for Urban Rail Traction and Network Control System

Release of Technical Specifications for Urban Rail Traction and Network Control System

The China Urban Rail Transit Association released a series of standards for traction and network control systems for electric buses in urban rail transit in April 2018:

Urban Rail Transit Electric Bus Traction System Part 1: Technical Specification for Traction Inverters (T/CAMET 04002.1-2018)

Urban Rail Transit Electric Bus Traction System Part 2: Technical Specification for Auxiliary Converters (T/CAMET 04002.2-2018)

Urban Rail Transit Electric Bus Traction System Part 3: Technical Specification for Charging Machines (T/CAMET 04002.3-2018)

Urban Rail Transit Electric Bus Traction System Part 4: Technical Specification for Asynchronous Traction Motors (T/CAMET 04002.4-2018)

Urban Rail Transit Electric Bus Traction System Part 5: Traction System Combination Test Method (T/CAMET 04002.5-2018)

Technical Specification for Control and Diagnosis System of Electric Train in Urban Rail Transit (T/CAMET 04003-2018)

This batch of standards was officially implemented from August 1, 2018.

The traction system is a key system in the electrical part of urban rail transit vehicles. The traction inverter, auxiliary converter, charger, and traction motor are key components of the system, and the reliability of the system and products is directly related to the normal operation of the train. The train control and diagnosis system is a key system in the electrical part of urban rail transit vehicles. The system performs functions such as train control, diagnosis, monitoring, and recording, and the reliability of the system and products is directly related to the normal operation of the train.

Common standards in this field include:

GB/T 25122.1 and IEC 61287-1 are general standards for power converters used in rail transit locomotives and vehicles,

GB/T 25123.2 and IEC 60349-2 are general standards for AC motors powered by electronic converters for rail transit locomotives and vehicles,

GB/T 25117.1 and IEC 61377 are general standards for combined testing of traction systems for rail transit locomotives and vehicles,

GB/T 25119-2010 is a general standard for the use, design, manufacturing, and testing of electronic devices on rail transit locomotives and vehicles,

GB/T 28029.1 and GB/T 28029.2 are the general standards for train bus (MVB, WTB) and train bus conformance testing (MVB, WTB) of traction electrical equipment,

IEC 61373:2010 is a general standard for impact and vibration testing of railway rolling stock equipment,

IEC 61375-3-4 is a universal standard for Train Communication Network (TCN) and Marshalling Ethernet (ECN) for electronic equipment in rail transit.

There are currently no specific industry or group standards for the traction and network control system of urban rail transit electric buses at home and abroad. The technical requirements and test methods of the system and components are not particularly clear or complete in the relevant standards and user requirements for vehicle/traction/network control systems used. Therefore, the plan is prepared based on the group standards of the China Urban Rail Transit Association, Proposed by the Technical Equipment Professional Committee of the China Urban Rail Transit Association, under the jurisdiction of the China Urban Rail Transit Association, Zhuzhou CRRC Times Electric Co., Ltd. has drafted this series of group standards.

The formulation of this series of standards is mainly based on or referring to the above general standards, industry standards published in relevant fields, and combined with the actual needs of the traction/network control system and its components in the urban rail transit industry in China. The usage conditions, technical and performance requirements, test methods, test rules, identification, packaging Transportation and storage are specified, and the test methods and rules of the traction system combination test are specified, which not only consider the consistency with the relevant standards, but also achieve operability, applicability and progressiveness, especially the latest version of the relevant international standards on technical requirements and test amendments, It can better adapt to the current technical status of urban rail transit related systems and improve the clarity of inspection criteria. Applicable to the design, manufacturing, inspection, testing, and certification of traction/network control systems and components for urban rail transit electric buses.
