STATOR WINDING INSTALLATION AND IMPREGNATION METHOD TO BE USED IN ASYNCHRONOUS AUXILIARY MOTORS Russian patent published in 2009 - IPC H02K15/12 B29B15/10 

Abstract RU 2361349 C1

FIELD: electric engineering.

SUBSTANCE: invention relates to electric engineering, and particularly, to devices intended for impregnating windings of driving motors in railway vehicles. According to the invention, the impregnation plant for asynchronous auxiliary motor stator windings includes the following: impregnation tank and storage tank for impregnating agent. Both tanks are interconnected by a pipeline. There is a filter in the pipeline to decontaminate impregnating agent. Both tanks are provided with heating elements, level metres, thermal sensors, pressure transducers and connected to vacuum system. The impregnation tank is equipped with U-sonic system, while storage tank is connected to the compressed air system. According to the stator winding impregnation method to be implemented on the above-mentioned plant, the stator winding is immersed into impregnation tank, heated to 120 - 140°C and cured until water vapours are removed from winding. Then, stator winding is cooled to 60-70°C, and pre-heated impregnating agent is supplied to impregnation tank. The impregnating liquid is subject to cavitation by means of U-sonic system and bubbling is generated due to compressed air supply. As a result, the shock waves clean the stator windings. The decontaminated impregnating agent is pumped into storage tank and vacuumed. Clean impregnating agent is again supplied to the tank for impregnation, vacuum system is actuated and air is removed from the tank and impregnating agent. Finally, U-sonic system is switched on, cavitation is created and deep impregnation of stator winding is conducted by applying shock waves.

EFFECT: increased rate of items saturation with impregnating agent by creating conditions of more effective gas and vapours removal from item surface and inter-turn space and from impregnating agents.
