| 摘要 | A dry transformer load switch, and transformer having such switch, has a hollow insulation cylinder extending longitudinally about a virtual center axis and has a plurality of connection contacts arranged along the inner circumference thereof, and a radially oriented main contact arranged in the interior of the hollow insulation cylinder so as to be rotatable about the center axis and which, with a corresponding rotary movement, can be optionally electrically connected by the radially outer end thereof to one of the connection contacts. In a hollow-cylindrical space about the center axis that is defined by the radially inner and outer end of the main contact, there is a barrier shield, which can be rotated together with the main contact about the axis. | ||||||
