Diagnostics of electric auxiliary converter of a direct current electric train using parameters of three-phase alternating current spectrum

Print

The carried out studies, as well as technical analysis of defects, malfunctions and unscheduled repair of electric trains revealed that in the system of the train’s auxiliary DC circuits that most liable to failures element is an electric auxiliary converter.

The paper describes a technology of diagnosing an electric train’s DC converter using three-phase alternating current spectrum parameters.

The examples of a three-phase alternating current spectrum of a faultless converter, and a converter in a pre-accident condition are given.
