Abstract (en)
The subject of the invention is a gas insulated electrical switchgear (1) placed in an enclosure (2) and provided with at least one bushing (4) for transferring electric energy through the enclosure of the switchgear. The bushing (4) has a conductor (5) for powering the switchgear (1) and has a form of a the cooling device which is integrated in the conductor (5) of the bushing (4). The cooling device is a heat pipe filled with a working fluid (8). One end of the heat pipe forms an electrical bottom terminal (11) connected with a conductive part of the switchgear (1) whereas the other end of the heat pipe forms an electrical top terminal (12) placed outside the enclosure (1) closing the switchgear (1).
