A method of manufacturing a wound insulator pipe, in particular for a high voltage insulator, having one or more ducts for conductors of any kind is provided. A laminate structure is achieved by winding a material onto a spindle and impregnating with a resin. Initially first layers of the material to be wound are applied; then at least one groove is made in the surface obtained and then the winding is completed until the final diameter is attained.

Method of producing a wound insulating pipe

An encapsulated installation, in particular a switching installation for high or medium voltage, includes a plurality of sensors located in an interior of an encapsulation. A central monitoring device is provided for information interchange with the surface acoustic wave sensors. An antenna element of the monitoring device is disposed at the encapsulation and is directed towards the interior. The sensors can be interrogated selectively.

Encapsulated installation

The invention relates to a compressed gas switch with two contact pieces, a contact element by-passing the contact pieces when in the on position, and two isolating distances connected to each other in series. The second contact piece opposing the first isolating distance is arranged axially by an annular piston to be displaceable forming a switching chamber. The switching chamber is separated from the heating chamber by a bulkhead partition having a current-dependent valve, and the second isolating distance is produced after opening of a blowing hole located between the second contact piece and the contact element.

Compressed gas power switch

A method for producing a wound insulating conduit, in particular for a high-voltage insulator, with at least one empty channel for subsequent insertion of a conductor, e.g., an optical fiber. First layers of a material to be wound are applied first, then a molded body provided with at least one empty conduit is applied to a resulting surface and wrapped by additional layers. The molded body has lateral projections which extend over an entire length of the empty conduit and are designed so that they correspond to the surface to which it is secured.

In a high-voltage outdoor switch including a housing and an interrupter unit arranged in it, two current transformers are arranged on the enclosure of the switch, one to each side of the intrrupter unit. It was previously to install current transformers separate from high-voltage outdoor switches. The construction complexity and the costs are reduced by the constructional combination of the switch with the current transformers.

High-voltage outdoor switch

Enclosed high-voltage electric line

An encapsulated tubular conductor having at least two antenna elements disposed on the capsule thereof for maintaining therebetween wireless information transmission in a transmitting-receiving direction, and a transmitting-receiving device located outside the capsule and assigned to one of the antenna elements includes another transmitting/receiving device also disposed outside the capsule and assigned to the other of the antenna elements, the antenna elements being directed towards an interior space of the capsule, the interior space serving as a transfer path via which information is transferable between the transmitting-receiving devices.

Encapsulated tubular conductor

A method for detecting the position of a switching device and an encapsulated switching installation having at least one switching device. A transmitted signal is emitted into the interior of an encapsulation to make it possible to easily detect the position of a switching device in an encapsulated switching installation. A resultant reflection signal is received and stored. After a repetition of this process, the two received reflection signals are compared with one another. In the event of any discrepancy, a message signal is produced for the new switching state.

Method of detecting the position of a switching device and encapsulated

A metalclad switchgear assembly for high or medium voltage, having a cladding, includes at least one sensor arranged in an interior space of the cladding for detecting a condition variable within the cladding, the sensor having an antenna; and a transmitting and receiving antenna directed towards the interior space, the transmitting and receiving antenna serving for performing a wireless information interchange with the sensor, and for simultaneously detecting electromagnetically partial discharges in the interior space.
