Embodiment Construction

[0039] exist figure 1 shows a perspective view of an on-load tap-changer 1 according to the invention, which is arranged directly below a transformer cover 2 of a tap-changer not shown in further detail. A more precise description of the components of the on-load tap changer 1 and their functions can be obtained from the following description of the drawings. Such a tapped transformer sufficiently known from the prior art comprises a transformer tank filled with insulating oil, in which transformer tank at least one winding is arranged on an iron yoke. This winding is divided into a dry winding and a regulating winding, on which a plurality of winding taps are arranged, which form the regulating range. Furthermore, the on-load tap changer 1 has a drive module 3 fastened to the underside of the transformer cover 2 , which cooperates with a motor drive 4 arranged on the opposite outer side of the transformer cover 2 . The motor drive 4 can here be designed, for example, as a c...

Abstract

The invention relates to an on-load tap-changer for uninterrupted switching between different winding taps of a tapped transformer, in which at least one selector contact unit each has a plurality of fixed selector contacts Arranged along a line, said plurality of fixed selector contacts are respectively electrically connected to the respective winding taps, said selector contacts being manipulable by means of two longitudinally movable selector contacts for uninterrupted switching, with two vacuum interrupters per phase, a motor drive for introducing the drive motion into the on-load tap-changer (1), the selector contact unit and the vacuum interrupters by means of the The motor drive (4) can be directly actuated, so that the drive movement of the motor drive is introduced into the selector contact unit and the vacuum switch tube without an intervening energy store. (3) Set on the underside of the transformer cover (2).

Description

technical field [0001] The invention relates to an on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer. Background technique [0002] On-load tap-changers have been used in large numbers all over the world for many years to switch between different winding taps of tapped transformers without interruption. So-called reactor switches, which are prevalent especially in North America, have a switching reactance which enables slow continuous switching. On-load tap-changers based on the resistance fast switching principle generally comprise a selector for the powerless selection of the corresponding winding tap of the tapped transformer to which it should be switched and a switch for the actual switching from the previous winding tap to the new preselected winding tap On-load toggle switch. For this purpose, diverter switches usually have switching contacts and resistive contacts. The switching contacts are used here for the di...
