Abstract: A pluggable high-voltage feed-through has an inner conductor, which extends in a longitudinal direction between a high-voltage connection and a plug-in section of the high-voltage feed-though. The plug-in section is configured for plugging the high-voltage feed-though into a device connection part of an electrical device. An insulating body surrounds the inner conductor. A test tapping point is provided with an electrical contact for connecting to a connection of a measuring device. The test tapping point is arranged outside the plug-in section. An electrical device has a fluid-tight housing and the high-voltage feed-through. A device connection part is provided for receiving and contacting the high-voltage feed-through.

Abstract: A high-voltage device has an inner conductor and an insulating member that surrounds the inner conductor along the longitudinal direction thereof. In order to increase the reliability of the high-voltage device, at least one optical waveguide rests against the inner conductor in at least some sections, extends out of the insulating member and can be connected to an evaluation unit for recording measured temperature values. Furthermore a method measures a temperature of the inner conductor of the high-voltage device.

Abstract: A high-voltage bushing can be plugged into a bushing socket of an electrical device of a high-voltage installation. The high-voltage bushing has an internal conductor, an insulating body which at least partly encloses the internal conductor, and a plug-in section for plugging the high-voltage bushing into the bushing socket. A heat pipe is provided in the internal conductor. The heat pipe is at least partly filled with a vaporizable cooling liquid and the heat pipe extends into the plug-in section. A high-voltage installation having the high-voltage bushing is also provided.

Abstract: A high-voltage device has an inner conductor and an insulating body, which surrounds the inner conductor along the longitudinal direction of the inner conductor. Electrically conductive control inserts for field control are arranged concentrically around the inner conductor and are spaced apart from each other by insulating layers. An electrically conductive connection extends between the inner conductor and a first control insert that is closest to the inner conductor. An electrically conductive connection extends between the inner conductor and a second control insert. The second control insert extends axially beyond the first control insert to a foot end of the high-voltage device.

Abstract: A high-voltage apparatus contains an internal conductor, an insulating body which surrounds the internal conductor along its longitudinal direction and has insulating layers which are composed of a synthetic material which is impregnated with a resin, and also electrically conductive control inserts for field control which are arranged concentrically around the internal conductor and are spaced apart from one another by the insulating layers. At least one of the control inserts is a contact insert which is electrically connected to the internal conductor by a contact-making device. The contact-making device has a contact element which is composed of electrically conductive material and is electrically connected to the contact insert. The contact element is fixed by adhesive bonding to a conductive substrate which is in electrical contact with the internal conductor.

Abstract: A high-voltage bushing for DC voltage in a gas-insulated, metal-encapsulated DC voltage switchgear assembly is provided with electrically conductive inserts. The novel high-voltage bushing is configured with a short, compact design, as it has at one or both ends, an inner conical cutout that opens towards the respective end.
