Abstract: A vacuum interrupter has a housing, a first contact system, which includes a movable contact piece and a fixed contact piece, and a second contact system, which includes a grounding contact and a grounded mating contact piece. The grounding contact is disposed on a movable contact rod, which is passed out of the housing in a sealing manner, with which vacuum interrupter an interaction of the arc with the grounded mating contact is prevented. The first contact system is held in the interior of the housing using vacuum-tight separating means, which divide the interior of the vacuum interrupter into a first interior having the first contact system and a second interior having the second contact system.

Abstract: A contact configuration for a vacuum switch includes cup-shaped contacts, which are movable one after another in a longitudinal direction and provided with slots for producing a radial magnetic field. A contact carrier whose side wall is provided with a front surface faces the opposite contact and a bottom section. Each contact has at least partially erosion-resistant contact elements, which cover at least the front surface and the internal bottom surface of the bottom section of the contact carrier facing the opposite contact.

Abstract: The aim of the invention is to achieve, in the simplest possible manner, a movement of an electric switch (3) of a medium-high voltage switch panel on a mounting structure (1) between an interrupt position, a test position and an operating position. To this end, a single mechanical control module (9) is integrated in the mounting structure (1). This control module (9) controls the individual movement sequences while simultaneously transferring the drive forces required therefor.

Abstract: The invention relates to a method for controlling an electrical switching module which can be displaced between an entry position and an exit position. The switching module comprises switching contacts of vacuum switching tubes; an isolating element which can be also be displaced in the switching module and comprises isolating contacts which can be connected to, and disconnected from, corresponding mating contacts inside an enclosed switchboard section, as required; and connector contacts and mating connector contacts in the low voltage range. The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating position.

Abstract: A locking device of an electrical switch which can be moved between a disconnected position and an operating position with the switching states of the electrical switch. A first strip has a control contour which extends in a first direction and has a ramp which interacts with a control rod which can be moved in certain states of the electrical switch.

Abstract: Drive devices for switchgear interrupter units, having movable contact pieces that can be controlled by solenoid drives are described. The drives of the movable contact pieces being controllable by linear motor drives. The interrupter units are realized by vacuum circuit breakers, and the linear motor drives are realized by three-phase AC linear motors. Each of these can be influenced by a control unit that optimizes the switching operations and that is provided with a mains connection. The three-phase AC linear motors are composed of individual components that determine thrust and range of motion. The individual components together constitute the drive of the movable contact parts. The individual components are determined by the number of motor coils and/or by the number of parallel motor modules.

Said switching module comprises switching contacts of vacuum switching tubes; an isolating element which can be also be displaced in the switching module and comprises isolating contacts which can be connected to, and disconnected from, corresponding mating contacts inside an enclosed switchboard section, as required; and connector contacts and mating connector contacts in the low voltage range. The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating element are represented by an “operating position” and by an isolating position.

Abstract: A device for monitoring the safety operation of power switches, in particular vacuum power switches in medium voltage switchboards. The device has a microprocessor unit that consists of a microprocessor, a microprocessor control and process-oriented storage means. The microprocessor is controlled by an angle pulse and a direction of a rotation recognition device. While the movement of the moving part of the power switch under the influence of states of operation is converted, the device detects the available data of the power switches. The device according to the present invention is especially well-suited in medium voltage switchboards for documenting and forecasting the real state of power switches.
