Abstract: In order to address the supporting equipment demands for constructing electrified railroads in the western plateau regions of China, oilfree air compressor for pantograph system of type DWT70A plateau railway electric locomotives was developed . According to the high altitude working conditions in Tibet, Qinghai and other provinces, research and design were carried out on thermal calculation of compressor, motors, piston rings, guide rings, lubrication, etc. and simulation tests for vibration, shock, high altitude working conditions. The results show that the compressor has stable performances, which fully meets the requirements of working conditions of plateau regions.
Key words: plateaus; locomotive; oilfree compressor
