GB/T 37863.1-2019 in English

GB/T 37863.1—2019 Standard Overview

GB/T 37863.1—2019 is a national standard of the People's Republic of China, which mainly stipulates the use conditions, system composition, technical requirements, test methods and inspection rules of the traction electric drive system of urban rail transit vehicles. This standard is applicable to urban rail vehicles powered by DC, including DC750V, DC1500V, DC3000V and vehicles powered by energy storage systems.

Comparison of standard frameworks

Technical background and evolution analysis

With the rapid development of urban rail transit, the technical requirements for traction electric drive systems are becoming increasingly stringent. From traditional DC drive to modern AC drive technology, the industry has undergone many technological innovations. In particular, the application of VVVF (variable voltage and frequency conversion) technology has greatly improved the operating efficiency and control accuracy of the system.

Implementation suggestions

To ensure that the traction electric drive system complies with the GB/T 37863.1-2019 standard, the following measures are recommended:

1. Selection and design stage: Select appropriate traction motors and converters according to line conditions and vehicle parameters.
2. Test verification: Carry out system combination tests in accordance with standard requirements to ensure that the performance of each component meets the standards.
3. Operation and maintenance: Establish a complete monitoring and fault diagnosis system, and regularly check the operating status of key equipment (such as high-voltage electrical appliances and brake resistors).
4. Staff training: Provide professional training for operators and maintenance personnel to ensure that they are familiar with the operating characteristics and protection functions of the system.
