Description
Summary:Traction convertor plays a main role to ensure the power of High-Speed EMUs. The temperature rising of the convertor directly impacts the reliability of the operation of EMUs and the life time of the convertor. This article analyses the power loss of the convertor, establishes the temperature rising model under the conditions of the cooling system, and designs the simulation software for temperature rising by taking the example of CRH3 High-Speed EMUs. This software monitors the temperature of the main parts of the traction convertor in the process of the EMUs operation, which provides the scientific basis for power configuration and the features of the temperature rising.
