Pole part of a medium-voltage or high-voltage switchgear assembly, and method for its production
The invention relates to a low-voltage, medium-voltage or high-voltage switchgear assembly as claimed in the preamble of patent claim 1, 9 and 10. In order to ensure in this case that heat that is created is dissipated better to the exterior for convection, the invention in this case proposes that a thermally conductive heat transmission element in the form of a cylindrical casing is provided between the vacuum interrupter chamber, a contact holder and the encapsulation casing, the inner surface of which heat transmission element rests on the vacuum interrupter chamber and the contact holder, and the outer surface of which heat transmission element rests on the encapsulation casing inner surface. Furthermore, a heat transmitter is proposed which can be produced from a thermally conductive plastic using the injection-molding or molding-compound production process. This can then be connected to the pole part through openings. A further option is to fit these heat transmitters before the encapsulation of an assembly with an encapsulation compound, and then to also cast them in.
