Embodiment Construction

[0032] figure 1 A schematic diagram showing an equivalent circuit diagram of a switching device for a three-phase consumer. The switching device is described below on the basis of a soft starter, but this is not to be regarded as restrictive. Consumers represent, for example, working machines, in particular permanently excited three-phase electric machines. In the respective wiring harness LS1 , LS2 , LS3 of each phase P1 , P2 , P3 a switching module is arranged. Each switch module includes a power module 10 1 、10 2 or 10 3 and bridge unit 20 1 、20 2 or 20 3 . The subscripts "1", "2" or "3" following the reference numerals in the figures indicate the corresponding elements of the phases P1, P2 or P3.

[0033] In the corresponding switch module, the power module 10 1 、10 2 、10 3Comprising two controllable semiconductor switching elements 11 connected in antiparallel 1 and 12 1 、11 2 and 12 2 and 11 3 and 12 3 . with controllable semiconductor switching elemen...

Abstract

The invention relates to a switching device for a single-phase or multiphase electric consumer. A switching device includes a number of line sections corresponding to a number of phases, each including a first and a second connection part, for connection to a connection phase of an electrical consumer. At least one controllable semiconductor switching element is provided per phase, wired between the first and second connection part. A bypass unit includes one controllable electromechanical switching element with a low on-resistance per phase. The controllable electromechanical switching element is wired, in parallel with the controllable semiconductor switching element of this phase, between the first and second connection part. The first and second connection part of a respective phase are arranged adjacently on one side of the power module in spatial proximity in a direction of extent. A contact bridge, assigned to a respective phase, runs in the direction of extent in order to electrically connect the first and second connection part in the switched-on state.

Description

technical field [0001] The invention relates to a switching device for single-phase or multi-phase consumers.
