Abstract

1514104 On-load tap changers MASCHINENFABRIK REINHAUSEN GEBR SCHEUBECK GmbH & CO KG 28 Oct 1976 [29 Oct 1975] 44816/76 Headings H1N and H1T An on-load tap changer for a tapped transformer comprises a load diverter switch 2, a changeover selector 4, a tap selector 3 comprising a cylindrical cage having two axially spaced end rings 7, 8, an elongate actuating member 13 rotatable step-wise about the axis of the cage for actuating the tap selector 3, a potential switch 5 for connecting a predetermined tap to a potential source having a hollow cylindrical body 14 of insulation material coaxial with the cage and supporting a fixed electrical contact 26, a lever 21 carrying a movable contact 25 and pivotably supported by the cage ring 8 facing the cylindrical body 14, the lever 21 being pivoted upon movement of the actuating member 13 to cause engagement and then disengagement of the contacts 25, 26 by a cam 27 mounted on the actuating member 13. The cage of the tap selector 3 is defined by insulating rods 9 connected to the end rings 7, 8 and carrying selector contacts 10, one of which is connected by a cable 16 to a terminal 15 provided on the insulating cylinder 14. The terminal 15 is connected to the fixed contact 26 via porcelain resistors (31) (Figs. 4 and 5, not shown) received in sockets (29) arranged on a helix on the inside wall of the insulating cylinder 14. The lower end ring 8 is provided with radial stays 17 secured to the insulating cylinder 14, one of the stays 17 pivotably supporting the lever 21 which is permanently connected to the cage ring 8 by terminal contacts 22, 23 biased together by a spring 24 which also biases the contact 25 on the lever 21 away from the fixed contact 26. When an actuating rod 13 is rotated by a gear 11, the cam 27 on the rod 13 engages a roller 28 on the lever 21 causing the contact 25 to engage the fixed contact 26. Subsequent movement causes the cam 27 to disengage the roller 28 whereby the electrical connection is broken. Three contact levers 21 may be provided to produce a three pole tap changer.
