The invention relates to a switch assembly (), in particular a preselector, for a variable transformer () having a first winding () and a second winding () with a first and a second tap (), said switch assembly comprising: a first connection terminal () that can be connected to the first winding (); a second connection terminal () that can be connected to the first tap (); a third connection terminal () that can be connected to the second tap (); a first, second, third and fourth fixed contact (); a vacuum interrupter (); a first moving contact () that can be contacted selectively with the first or second fixed contact (); a second moving contact () that can be contacted selectively with the third or fourth fixed contact (), wherein the second and the fourth fixed contact () are connected to the second connection terminal (), the first and the third fixed contact () are connected to the third connection terminal () the first moving contact () is connected to the first connection terminal () via the vacuum interrupter (), and the second moving contact () is connected to the first connection terminal ().

Preselector switch assembly for a variable transformer

A switching arrangement (), in particular a polarity switching means, for a control transformer () which comprises a first winding () for a phase of an AC power supply system, which phase is to be controlled, comprises &#x2014;a first connection terminal () which can be connected to the winding (); &#x2014;a second connection terminal () which can be connected to a discharge line (); &#x2014;a vacuum interrupter (); &#x2014;an isolator (); &#x2014;a resistor () which is connected in series with the vacuum interrupter () and the isolator (); wherein &#x2014;the first connection terminal () is connected to the second connection terminal () by means of the series circuit.

Switching arrangement for a control transformer, in particular polarity switching means

A circuit () for an electrical plant () with a first and a second control winding () comprises

Switching circuit with two load tap changers, electrical assembly with such a switching circuit, and use thereof

The invention relates to a switching arrangement () with a pre-selector () for a power transformer () which has multiple windings (). The pre-selector is designed to optionally connect at least one first winding () to one of the two end contacts () of at least one second winding (). At least one first switch is arranged in the connection between the pre-selector () and the first winding (), thereby allowing the pre-selector to be switched in an arc-free manner and thus in a gas-free manner as well.

Switching system with preselector

The invention relates to a step switch, comprising a pre-selector and a fine selector. The invention is characterized in that the step switch has a connection () between the pre-selector and the fine selector (), at least one coupling switch () being arranged in said connection. A pre-selector can be switched in a largely gas-free manner by means of said switchable connection with the aid of the fine selector.

A load selector for tapped transformers has an oil tank and a preselector having a first preselector contact and a second preselector contact for each phase to be switched by the load selector. The first preselector contact and the second preselector contact are mounted on a wall of the oil tank and extending through the wall of the oil tank. A first zero contact and a second zero contact separate from the first zero contact are provided for each phase to be switched by the preselector. The first zero contact and the second zero contact are each mounted on the wall of the oil tank and extend through the wall of the oil tank.
