| Abstract: | Failure mode effects analysis is a common method for reliability analysis. In this paper, traction transformer of electric multi pie unit is the analysis object. Traction transformer components are grouped according to different functions. Transfer process of ener gy, material and signal in traction transformer are illustrated by functional block diagram. Modes, causes, effects and detection meth ods of failures are analyzed, severity are divided into several levels qualitatively. The consequent of this paper is failure mode effects a nalysis table. The traction transformer failures are in detail analyzed, it plays a guiding role in maintenance and technical alteration. |
