A method of the transformer load switching the transformer for carrying out the method
Original language description
The method of switching the load on a transformer with at least two branches where the load is connected to the first branch of the transformer consists in the fact that, after disconnecting the main earthing winding of the transformer from the zero potential, subsidiary earthing winding with a higher impedance than the impedance of the main earthing winding is connected to the transformer, then the load is connected to the second branch of the transformer winding, then the load is disconnected from the first branch of the transformer winding, then the subsidiary earthing winding is disconnected from the transformer and then the main earthing winding of the transformer is connected to the zero potential. The transformer (1) connection for load switching is as follows, the main earthing winding (4) is connected to the zero potential (13) of the supply voltage via the main earthing winding contactor (8). Two transformer (1) branches, including the first winding branch (2) and the second winding branch (3) are connected by the contactor (6) of the first winding branch and contactor (7) of the second winding branch to the load connected to the zero potential. The contactor (8) of the main earthing winding is connected to the control unit (11) of the contactors (8) of the main earthing windings. The contactor (6) of the first winding branch and the contactor (7) of the second winding branch of the transformer (1) are connected to the control unit (10) of the branch winding contactors which is connected to the control unit (10) of the earthing winding contactors. The transformer (1) is provided with the subsidiary earthing winding (5) connected to the zero potential via the contactor (9) of the subsidiary earthing winding.
