Abstract
749,317. Switching systems for transformers. ELECTRICITE DE FRANCE. July 23. 1953 [July 24, 1952], No. 20497/53. Class 38 (4). On-load tap-changing equipment for a transformer having a winding, or windings, I-III tapped at three points A-C, comprises relayoperated switches 1-3 for directly changing the taps as desired, the equipment being formed as a unit separate from the transformer and requiring no connection thereto other than by the readily removable electrical connections between the tapping points and the switches. A further relay switch 4 controls the temporary insertion of impedances 4 in circuit during a change of tap to prevent the short-circuiting of adjacent taps. The switches are controlled by a manual, or automatic, control member, the order of operation of the switches 1-4, consequent upon movement of the control member, being determined by a set of relays connected electrically to the control member and to auxiliary contacts of the switches, the arrangement being such that an incorrect, or incomplete, sequence of operations results in the operation of circuit breakers which effect deenergization of the transformer.
