<p>The invention relates to a three-phase transformer with mobile short-circuited coils for the continuous regulation of supply voltage for a three-phase consumer. According to the invention, the three-phase transformer consists of two identical single-phase modules () joined in a three-phase assembly with V-connection, each of said modules () representing a single-phase magnetic system with columns, on one column there being placed a primary winding divided into two identical sections () arranged at the column extremities and serially connected to one another, as well as a mobile short-circuited winding () which is concentric with the first winding and is mounted between two plates (), being movable due to a screw shaft () integral with a handling wheel (); the primary winding is serially connected with an auxiliary winding () intended to compensate a residual voltage corresponding to the zero position, which is placed on another column.</p> |
