Variable transformer output winding with double-entry

摘要

Variable transformer windings with double entry, which consists of ferromagnetic core (1) of the insulating frame coil (7), in which the coiled coil input (2) with an insulating layer (6). At this output is internally wound coil (3) with an insulating layer (5) and external output coil (4). On the exposed surface of the coil is pressed against the sliding collector (8), which is moving through the inlet (9) connected to the collector terminal (10). Start (20) of the internal output coil (3) is associated with early (22) the external output coil (4) and is also connected to the terminal beginnings (12) and also the end (17) of the internal output coil (3) is connected to the end (19) the external output coil (4) and is also connected to the terminal ends (11). In this arrangement the output winding leads to the fact that the inner coil of the transformer output winding regulator is highlighted by its voltage effect as if there were additional (virtual) Pick touching the surface of the internal output coil in the same position as the true collector of the external coil output regulatory transformer windings. The net effect is the fact that such a regulatory transformer is taken by the position of the collector voltage and current is drawn by the sum of (surface) cross-section conductors external and internal output coil in the permissible current density.
