摘要： The invention relates to a tap switch for uninterrupted changeover between two winding taps (tap n, tap n+1) of a tapped transformer, wherein each of the two winding taps is connected to the common outgoing load line via in each case a mechanical switch (Ds) and a series circuit which is arranged in series therewith and which is composed of two oppositely connected IGBTs (Ip, In). According to the invention, each IGBT is bridged by in each case a specially dimensioned varistor (Vp, Vn) connected in parallel therewith.

摘要： An apparatus for regulating electrical voltage in multiphase power mains has a control transformer having for each phase of the power mains a primary winding and a control winding having three taps. The second tap is connected centrally between the first and third taps and to one of the ends of the primary winding. This control winding has winding lengths between the first and second taps and second and third taps equal to a whole-number multiple of a winding length of the primary winding. Three circuit elements have inputs connected to the taps. A reactor winding has ends connected to outputs of the first and second circuit elements, while the output of the third circuit element electrically connected to the output of the first circuit element. A further circuit element is connected across the reactor winding, and an output is connected to a center of the reactor winding.

摘要： A position indicator for step switches and tap selectors of transformers and the like has a contact array connected to the motor drive and connected by a plug to the plug of a connector which, in turn, is connected by plugs to the information-generating module which outputs to the display. One of the pairs of plugs between the contact array and the connector or between the connector and the module can be reversed relative to the other to signal a different sense of rotation of the motor drive.

摘要： A step-transformer drum formed with throughgoing apertures each centered on a respective axis has a contact assembly in each aperture having an insulating washer lining the aperture and having an inside part lying on an inside surface of the drum and an outside part lying on an outside surface of the drum. A stud has an enlarged head bearing outward on the inside washer part and a shaft projecting through the washer past the outside washer part and formed outside the outside washer part with a transversely throughgoing hole. A pin extends transversely through the hole and bears inwardly on an outwardly directed ramp so that rotation of the stud and pin in one direction relative to the structure makes the pin ride up on the ramp and tightens the stud in the aperture and opposite relative rotation loosens the stud.
