Abstract
With the rapid development of high-speed railway, both the speed of high-speed EMU and the capacity of electrical equipment are increasing. However, the problem of increasing equipment temperature rise is becoming more and more serious. Firstly, this paper investigates the research status of the temperature rise of traction transformer. Secondly, aiming at the temperature rise calculation of traction transformer of high-speed EMU, this paper first establishes the traction system simulation model, and then calculates the temperature rise of transformer based on the established model so as to complete the temperature rise calculation under the normal working state of the train.
