A switch assembly including a switch and a drive system for the switch. The drive system includes a motor for driving the switch, a control device with a power section for supplying power to the motor, a controller for initiating a switching operation of the switch by control of the power section, and a protection circuit. The protection circuit is configured to detect a first error signal via a state contact of the controller in the event of a malfunction of the controller, detect a second error signal via a state contact of the power section in the event of a malfunction of the power section, and initiate a safety measure depending on the first and the second error signal. The control device is configured to activate the protection circuit prior to the switching operation being initiated and to deactivate it following successful execution of the switching operation.

Switch assembly and method for safely operating a switch assembly

A switch assembly has a switch; and a servo drive system for the switch. The servo drive system includes: a motor configured to drive the switch; a power section configured to supply power to the motor; and a control unit configured to control the power section depending on at least one desired value. The control unit is configured to identify the presence of at least one safety-relevant event and, in the case of the safety-relevant event, to transmit at least one control signal to the power section. The power section is configured to initiate or carry out at least one safety measure depending on the control signal.

Switch assembly with drive system, and method for safely operating a switch assembly

A method carries out a switchover of a first switch or at least one second switch for equipment. The method includes receiving, by a controller, a switching signal; selecting, by the controller, the first switch or at least the second switch for switchover on the basis of the switching signal; querying, by the controller, at least one parameter of the first switch or the at least second switch; checking a locking condition on the basis of the at least one queried parameter for the first switch or a locking condition for the at least second switch; and carrying out the switchover by the selected first switch or the at least second switch based upon the corresponding locking condition being met.

Method for carrying out a switchover of at least two switching means for equipment, and drive system for at least two switching means in equipment

A drive system drives a switch. The drive system includes: a drive shaft connecting the drive system to the switch; a motor configured to drive the drive shaft; a feedback system; and a controller. The feedback system is configured to: determine at least one value for a position of the drive shaft; and generate a feedback signal based on the at least one value. The controller acts on an operation of the motor depending on the feedback signal.

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

In a method for cleaning an on-load tap changer () in a regulating transformer (), provision is made for the on-load tap changer () to comprise a moving contact () and a fixed contact (); for a cleaning signal to be generated; for the moving contact () to be frictionally moved relative to the fixed contact () on the basis of the cleaning signal. An on-load tap changer () in a regulating transformer () comprises: &#x2014;a moving contact () and a fixed contact (); &#x2014;a contact drive () which is coupled to the moving contact (); &#x2014;a control device () which is connected to the contact drive () and is designed in such a manner that the control device can generate a cleaning signal and can transmit said signal to the contact drive (); wherein the contact drive () is designed in such a manner that the contact drive can frictionally move the moving contact () relative to the fixed contact () on the basis of the cleaning signal.

Method for cleaning an on-load top changer, and on-load tap changer

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

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.
