Ventilation System for AC Drive Express Passenger Electric Locomotives

In order to make the design of ventilation system for electric locomotives more correct and reasonable, calculations were made to the ventilation system, which focused on the traction motor ventilation system and the machine room micro-positive pressure control, of the AC drive express passenger electric locomotives by combining the digital simulation calculation with traditional experiences. Optimized proposals were also given according to calculation results. Correction factors for design calculation were derived from the comparison drawn between the calculation results and test validation results. It showed that the design calculation of the ventilation system could lay a foundation for design optimization, and shorten the design cycle and reduce test costs.
