METHOD OF DRYING THE INSULATION OF TRACTION ELECTRIC MOTORS Russian patent published in 2018 - IPC H02K15/12 

FIELD: transportation.

SUBSTANCE: invention relates to railway transport, and more particularly to traction electric motors of electric locomotives. Method of drying the insulation of electric locomotive traction motors, in which current drying is performed using its own technical means of an electric locomotive, covers at least one group of traction engines, including traction motors of one trolley. Drying process is carried out under the control of a microprocessor-based control and diagnostics system using an active insulation resistance monitoring circuit with the help of integrated insulation resistance meters directly on the locomotive when it is stationary by supplying voltage from the contact network to the converter of own needs for powering it with a static converter of the traction motors of each group to be dried by a direct current of low voltage of 300 A, the excitation windings and anchors of which are connected in series circuits.

EFFECT: technical result consists in the effective current drying of the isolation of traction motors by the technical means of the locomotive by the forces of the driver with an effective target power consumption.
