Publication number: 20250149276Abstract: A switching device has an isolating or earthing function. The switching device contains an encapsulation housing filled with an insulating gas, a first contact arrangement with a first main contact and a first arc contact, a second contact arrangement with a second main contact and a second arc contact, and a nozzle arrangement which is configured to subject a switching arc between the arc contacts to an insulating gas flow. The contact arrangements are moveable relative to one another between a first end position and a second end position. During the movement from the first end position to the second end position, the main contacts are isolated from one another upstream of the arc contacts and a switching arc between the arc contacts is quenched by subjecting the switching arc to an insulating gas flow.Type: ApplicationFiled: November 25, 2022Publication date: May 8, 2025Inventors: Paul Gregor Nikolic, Frank Reichert

Patent number: 12040143Abstract: A separating wall for dividing a heating volume of a power circuit into a first sub-volume and a second sub-volume. The separating wall is formed with at least one wall opening which allows a flow of gas between the sub-volumes. The wall opening has an aerodynamically active opening surface based on a pressure difference between a pressure in the first sub-volume and a pressure in the second sub-volume.Type: GrantFiled: August 12, 2020Date of Patent: July 16, 2024Assignee: Siemens Energy Global GmbH & Co.

Patent number: 11862420Abstract: An interrupter unit for a circuit breaker includes a gas-insulated housing, which is fillable with a quenching gas, and a gas-guiding structure, which is disposed in the housing and has a guide tube and at least one diverting element. The guide tube extends in tubular manner about a longitudinal axis of the interrupter unit in order to guide hot gas, which is created in an electric arc region of the interrupter unit by the heating of quenching gas by an electric arc, away from the electric arc region. The at least one diverting element is configured to set hot gas exiting from the guide tube in a circular flow running around the longitudinal axis.Type: GrantFiled: October 21, 2019Date of Patent: January 2, 2024Assignee: Siemens Energy Global GmbH & Co. KGInventors: Claudia Wiesinger, Frank Reichert

Patent number: 11587748Abstract: A high-voltage power switch, preferably with a dead tank design, contains: a switching unit that has a switching device and an actuation element that is axially movable in relation to a longitudinal axis of the switching device to actuate the switching device and a closing resistor unit that has a closing resistor arrangement and an adjusting element that is axially movable in relation to a longitudinal axis of this closing resistor arrangement to actuate the closing resistor arrangement. The actuation element is coupled to the adjusting element in order to move the latter. Accordingly, the longitudinal axis of the switching unit and the longitudinal axis of the closing resistor unit are spaced apart, and the actuation and adjusting elements are coupled by a coupling device of the high-voltage power switch.Type: GrantFiled: January 30, 2019Date of Patent: February 21, 2023Assignee: Siemens Energy Global GmbH & Co. KGInventors: Radu-Marian Cernat, Armin Grund, Johannes Kern, Friedrich Loebner, Andrzej Nowakowski, Frank Reichert, Jens Schimmelpfennig, Andre Singer, Wolfgang Soerries, Stefan Wilke

Patent number: 10685798Abstract: An interrupter unit for a circuit breaker has two electrically conductive arcing contact pieces, which can be moved relative to one another along a switching path. An insulating nozzle has a nozzle channel through which the switching path runs. A heating volume is connected to the nozzle channel. A separating housing divides the heating volume into a cold gas region and a hot gas region. A cold gas duct runs through a nozzle channel end section of the nozzle channel and is connected to the cold gas region. A hot gas duct runs through the nozzle channel end section and is connected to the hot gas region.Type: GrantFiled: July 6, 2017Date of Patent: June 16, 2020Assignee: Siemens AktiengesellschaftInventors: Radu-Marian Cernat, Volker Lehmann, Andrzej Nowakowski, Frank Reichert

Publication number: 20110182205Abstract: A method and apparatus for conducting remote discovery of services across different local networks. A service discovery gateway in one local network issues a request for discovery information on the services in the opposite local network, embedded in a presence subscribe message over an IMS network. Discovery information is then received in a generic format embedded in a presence notify message over the IMS network. The received discovery information has been collected by a service discovery gateway in the first local network using a local service discovery protocol in the first local network. The received discovery information is announced to devices in the second local network, using a local service discovery protocol valid within the second local network. Thereby, local services can be provided and utilized across different local networks, even when different device-specific service discovery protocols are used within the local networks.Type: ApplicationFiled: October 15, 2007Publication date: July 28, 2011Inventors: Martin Gerdes, Andreas Fasbender, Andreas Häber, Frank Reichert

Patent number: 6122263Abstract: A method and system are disclosed for use with a mobile radio network, which receives and analyzes packets from a packet-switched fixed network, such as the Internet, and depending on the type of information received (e.g., speech, low speed data, or high speed WWW data), routes the information over an appropriate radio air interface to a mobile radio terminal. The speech information can be routed to mobile radio terminals over a conventional circuit-switched mobile radio link (e.g., a GSM traffic channel), the low speed data can be routed over a packet-switched mobile radio link (e.g., a GPRS traffic data channel), and the high speed data can be routed over a wideband broadcast radio link (e.g., a DAB network radio link). As a result, mobile radio terminals can advantageously enjoy full access to the Internet and thereby communicate effectively over the Internet with other mobile and wire-bound terminals.Type: GrantFiled: June 10, 1997Date of Patent: September 19, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Steinar Dahlin, Frank Reichert, Ina Widegren
