Abstract

The invention relates to a linear selector (1) for power-free preselection of tap contacts for a tapped transformer (100). The linear selector (1) according to the invention is cost-effective, simple and compactly constructed. The functions of a selector and a reverser are thus better connected. The linear selector (1) is constructed from a fine selector (2) and a reversing switch (3). The fine selector (2) and the reversing switch (3) are directly driven via a common gear unit (6).

Description

technical field [0001] The invention relates to a linear selector for powerless preselection of step contacts of a variable transformer. Background technique [0002] A step regulator for transformers is known from DE 913 933 B. The step regulator has a motor drive that drives a load switch and two step selectors. One of the stage selectors preselects odd-numbered stages of the transformer, while the other stage selector is responsible for preselecting even-numbered stages. The actual switching is performed under load through a load switch. Each of the step selectors has a slide running along the guide, which slide is driven by traction means running on guide rollers via a drive on the means. Each slide has switching contacts with which an electrically conductive connection can be established between the contact rail and the stages of the transformer. [0003] The individual selectors are alternately actuated by intermittent transmission and the stages of the transformer...
