TRANSFORMER CONTINUOUSLY ADJUSTING THE IN-LOAD VOLTAGE

摘要

The invention relates to a transformer continuously adjusting the in-load voltage, provided with a rotary secondary winding and an integrated driving system. According to the invention, the transformer consists of an "in-shell" type magnetic system (1) provided with an upper circular front yoke (1") having a cut-out (d) in its center to allow a cylindrical column (1') to pass therethrough, on said column there being concentrically located a fixed primary winding (2) and a rotary secondary winding (3), between the cylindrical column (1') and the upper front yoke (1") there being established an air gap (j) which is penetrated by a conductive bridge (3"') connecting the upper extremity of the secondary winding (3) and a cylindrical "cup" like rotor (7) mounted in the extension of an electrically insulating cylinder (3') of the secondary winding (3), the latter being driven by means of a stator (8) of an asynchronous three-phase motor secured to the upper front yoke (1").
