METHOD FOR JET-TRICKLING IMPREGNATION OF WINDINGS OF ELECTRICAL ARTICLES Russian patent published in 2014 - IPC H02K15/12 

FIELD: electricity.

SUBSTANCE: impregnating composition is fed from a container in form of a jet rotating along front parts of the windings, wherein the jet of the impregnating composition is charged with an electrostatic charge by passing it along the surface of a high-voltage electrode; the winding conductor is earthed and the jet is rotated by passing it through an inductor which generates a rotating magnetic field. The sign of the electrostatic charge of the jet is periodically varied to the opposite sign by transmitting inverted high-voltage pulses to the high-voltage electrode, wherein the duration of each pulse is equal to the period of rotation of the jet along the front part.

EFFECT: method increases efficiency of impregnating windings by 1,3-1,4 times.
