Description

The present invention relates to a device for an electrical unit consisting of a transformer and a generator. The stator of the latter is equipped with a squirrel cage type core winding, the rods of which are connected on the one hand by a short-circuiting ring and on the other side are directly connected to separate phases of the transformer primary winding.

In FIG. 1 and 2 schematically depict the proposed unit in two projections; FIG. 3-4 - wiring diagram of the secondary windings of the transformer .V

In the grooves of the stator 2 generator laid, as already noted above, the winding in the form of squirrel cells. The ends of the rods 4 (Fig. 1 and 2) of this winding connected on one side by a short-circuiting ring are terminated by spirals forming the cylindrical primary windings of the transformer. The latter are superimposed on individual cores b, which are closed by a common conduit 5, and are interconnected. These cores are also equipped with separate secondary windings 7 (Fig. 2). The number of phases of such a transformer will be equal to the number of cores of squirrel windings of the core for a pair of poles.

- The power supply of the transformer primary winding comes from the rods

squirrel cage in which currents arise during the rotation of the rotor.

To obtain a three-phase secondary system with a multi-phase primary, a zigzag connection of individual phases can be used for the secondary winding (Fig. 3).

To obtain direct current according to the transverter method, the said unit is supplied with a collector 8 to the individual plates of which the respective phases of the secondary winding 7 of the transformer are connected (Fig. 4).

The subject matter of the invention.

. An electrical unit consisting of a transformer and a generator, provided on the stator with a rod type winding squirrel cage, the rods of which on one side are connected by a shorting ring and on the other directly connected to separate phases of the transformer primary winding, characterized in that they are connected to the ends of the rods the stator windings the cylindrical primary windings of the transformer are assembled into separate, also equipped with separate secondary windings, of the transformer magnetic cores with common to all the cores of the rocks and connected to each other.

2. In an aggregate according to claim 1, use the secondary winding of the transformer for zigzag activation of individual phases in order to obtain a three-phase secondary system in a multiphase primary.
