Abstract: A de-energized tap changer for transformers comprises a frame of insulating material, a slide which carries movable contacts, the slide being displaceable in the frame, and a drive for the slide. The frame of the tap changer is manufactured in one piece and consists of a terminal bar with attachment means for connections from the transformer windings, a carrier member carrying the drive, and cross-bars connecting the terminal bar and the carrier member. The movable slide is displaceable in grooves in the cross-bars and can be inserted in the grooves only when situated outside its ordinary working area.

Abstract: A tap changer for transformers includes a selector switch and a diverter switch. The drive device for the switch includes a gear segment which drives a gear wheel mounted on a shaft which gear wheel also carries a slewing bracket on which is pivoted on a pivot pin a link which is connected to one end of a spring, the other end of which is stationary. The gear wheel has a notch extending partly around its periphery, into which the pivot pin extends so that the gear wheel can turn freely through a limited distance without affecting the spring. On the same shaft is mounted a fly wheel which has an arcuate slot into which the pivot pin extends. A braking arrangement is provided which holds the fly wheel against movement until it is forceably turned by the pivot pin. The fly wheel carries a projection which engages in a Maltese cross arrangement for shifting the contacts of the diverter switch.

Abstract: A mechanical brake for the driving device of a tap changer includes a brake disc and cooperating brake shoes. A control disc driven simultaneously with the brake disc has two parts of different radius, the higher parts of which can engage against a roller journalled on a lever which is pivoted on the shaft which controls the contact device supplying current to the driving motor. The roller carrying lever also has pivoted to it a link connected to a control rod which passes between the brake shoes and has thinner and thicker parts. Rollers journalled on the brake shoes engage this rod, so that when it is moved in either direction from a median position by the rocking of the lever it pushes the brake shoes apart and releases the braking action.

Abstract: A TAP CHANGER FOR TRANSFORMERS HAS STEP SELECTORS AND LOAD CONNECTORS. THE STEP SELECTOR HAS A CENTER PART PROVIDED WITH CARRIER MEMBERS FOR MOVABLE CONNECTION CONTACTS AND SLIP RINGS FOR BRUSHES. THE CARRIER MEMBERS ARE FORMED OF TWO PARALLEL RODS OF INSULATING MATERIAL, BOTH MOUNTED TO TURN AROUND THE AXIS OF THE CENTER MEMBERS ARE ROD CARRIERS A NUMBER OF MOVABLE CONNECTING CONTACTS AND A CORRESPONDING NUMBER OF SLIP RINGS. THE TWO RODS ARE POSITIONED INSIDE THE SLIP RINGS SO THAT THEY CAN BE PIVOTED STEPWISE IN RELATION TO EACH OTHER THROUGH SUBSTANTIAL ANGLES.
