Device for detecting partial discharge from gas-insulated high-voltage equipment, and related high-voltage substation equipment

摘要

The present invention relates to an apparatus for detecting a partial discharge in a gas-insulated high voltage installation. The said apparatus is mounted | worn with the surface of the electrical insulation part (1) in the outer side of the said high voltage installation. The electrical insulating part (1) holds a high voltage bar arranged inside the high voltage facility. The surface forms a rotationally symmetric cylindrical body on the surface of the high voltage equipment. The device is fixed to the surface of the electrically insulating material strip (6) and to the high-voltage installation, the conductive strip (2) being wound to contact only at least part of the surface. And an electrical shield part (5) disposed above the electrically insulating material strip (6). [Selection] Figure 5
