Abstract
A control device is for a commercially available switchgear and an electronic power module. Compactness of the device is improved so that it can be used in a switchgear cabinet. To this end, the power module is placed onto the switchgear on the side facing away from its bottom wall and the dimensions of the power module are adapted to the base contour of the switchgear so that the peripheral contour of the power module extends beyond the base contour only slightly, if at all, wherein at least the width of the contactor does not extend beyond it.
Claims28
A control device with an electromagnetic switchgear apparatus, comprising:
- a switchgear apparatus housing, including a bottom wall forming a base area of the switchgear apparatus;
- and
- an electronic power module, electrically connected to the switchgear apparatus and including a module housing, wherein the switchgear apparatus serves as an electrical bridging unit, wherein the electronic power module is placed onto the switchgear apparatus on its side remote from the bottom wall, wherein a structural width of the power module does not exceed a width of the base area of the switchgear apparatus, wherein an internal space of the module housing includes three mutually insulated chambers, each with an electronic switching unit arranged therein, wherein the electronic switching units each include power semiconductors electrically connected back-to-back, clamped between two metal plates of relatively high thermal conductivity, with one of the metal plates being connected to a heat sink, and wherein a fan is arranged in each of the three chambers.
A control device with an electromagnetic switchgear apparatus, comprising:
- a switchgear apparatus housing, including a bottom wall forming a base area of the switchgear apparatus;
- and
- a power module, electrically connected to the switchgear apparatus and including a module housing, wherein the power module resides on the switchgear apparatus on its side remote from the bottom wall, wherein a structural width of the power module does not exceed a width of the base area of the switchgear apparatus, wherein an internal space of the module housing includes a plurality of mutually insulated chambers, each including a fan and an electronic switching unit, wherein at least one of the electronic switching units include power semiconductors clamped in between a plurality of metal plates of relatively high thermal conductivity, and wherein at least one of the metal plates is connected to a heat sink.
