A high-voltage bushing has an insulator, which contains an insulating gas and an insulating solid, and an inner conductor which is led through the insulator. A mounting flange is employed for the mounting of the high-voltage bushing on a wall. A sensor, which is arranged on the mounting flange and is configured for the detection of at least one reaction product of the insulating gas and/or of the insulating solid. A corresponding method monitors an operating state of the high-voltage bushing.

High-voltage bushing and method for monitoring its operation

An insertable high-voltage bushing includes an inner conductor which extends in a longitudinal direction between a high-voltage terminal and a plug-in section of the high-voltage bushing. The plug-in section is configured for the insertion of the high-voltage bushing into a device connection part of an electrical device. An insulating body at least partially extends around the inner conductor. A housing at least partially extends around the outside of insulating body. The housing includes a tubular housing element which extends between a head fitting at the high-voltage terminal of the high-voltage bushing and a mounting flange for fastening the high-voltage bushing to a device housing of the electrical device. The housing element is made of a composite material and a secondary insulation provided between the housing element and the insulating body is formed of a dry foam.

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.

A pluggable high-voltage bushing includes an inner conductor which extends in a longitudinal direction between a high-voltage terminal and a plug-in section of the high-voltage bushing. The plug-in section is configured to plug the high-voltage bushing into a device connection part of an electrical device. An insulating body surrounds the inner conductor. The insulating body includes a textile sheet-like structure. An electrical device having the high-voltage bushing is also provided.

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.

A high-voltage bushing contains an insulating body that is arranged concentrically around a cylindrical winding support formed of an electrically-conductive material, conductive control inlays which capacitive potential control the high-voltage bushing and are spaced apart from one another by insulation layers, and are arranged concentrically with the winding support. A connection device is provided for establishing an electrical connection between a first control inlay closest to the winding support, and the winding support. The high-voltage bushing is characterized in that the connection device contains an electrical sliding contact.

High-voltage bushing

A high-voltage bushing has an internal conductor and an insulating body which surrounds the internal conductor along its longitudinal direction. The internal conductor is routed out of the insulating body at a head end of the high-voltage bushing. A fastening flange is arranged on the insulating body at an end opposite the head end. An outer housing encloses the internal conductor and the insulating body from the fastening flange up to and including the head end in a moisture-tight manner. A high-voltage installation has a high-voltage conductor which is routed through a housing wall of the high-voltage installation by way of the novel high-voltage bushing.

High-voltage bushing and high-voltage installation with the bushing

A high-voltage bushing includes an insulating body disposed concentrically around a cylindrical winding support formed of electrically conductive material, and a sealing device for sealing a gap between the winding support and the insulating body. The sealing device includes a sealing element disposed in a circumferential sealing groove. The circumferential sealing groove is disposed in the winding support and accommodates the sealing element. A method for producing a high-voltage bushing includes placing an insulating body concentrically around a cylindrical winding support formed of electrically conductive material. The insulating body has mutually concentrically disposed insulating layers. A sealing element is introduced into a circumferential sealing groove in the winding support, and the insulating body is subsequently impregnated with a resin to seal a gap between the winding support and the insulating body.

High-voltage bushing and method for the production thereof

A high-voltage insulator has an insulating body which is arranged around a high-voltage conductor. The high-voltage insulator has a damping chamber which at least partially engages around the insulating body and which is filled with an electrically insulating damping medium for damping an action of external mechanical force on the insulating body. A transformer bushing for routing a high-voltage conductor out of a transformer housing in an electrically insulating manner is further disclosed. The transformer bushing is characterized in that the transformer bushing contains a high-voltage insulator.

High-voltage insulator

A high-voltage bushing with conductive inserts for a DC voltage has a bushing body surrounding a high-voltage conductor and containing a paper insulation. The bushing body tapers conically, at least at one end region thereof, from a ground-potential-side location to a high-voltage-side end and is surrounded by an insulating barrier. In order to provide a high-voltage bushing of this type with a particularly good potential distribution, the outside of the bushing body is coated at least in the region of the at least one end region with a coating to form a coating layer, which has a greater electrical conductivity than the bushing body.
