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

Mounting structure for an electric switch

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. Only the isolating contacts are disconnected from the mating contacts in a test position which is situated between the operational position and the isolating position. The connector contacts are also disconnected from the mating connector contacts in the isolating position of the isolating element. When the switching module is switched from the isolating position to the exit position, the closing spring and the opening spring are forced into an unstressed state. One such method is used to control displaceable switching modules in medium voltage switchboard sections.

Method for controlling a displaceable electrical switching module

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.

Locking device

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.
