Publication number: 20220293366Abstract: 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: ApplicationFiled: August 12, 2020Publication date: September 15, 2022Inventors: Radu-Marian Cernat, Thomas Chyla, Frank Reichert, Joerg Teichmann

Publication number: 20090120910Abstract: An interrupter unit of an electrical switching device has a flow-conducting body. Gases which are flowing away are guided by way of the flow-conducting body. The flow-conducting body is formed at least from a first and a second element, wherein a joint gap is formed between the two elements. The joint gap has a section, which is formed with a complementary shape between the two elements so as to form a labyrinth structure.Type: ApplicationFiled: March 30, 2007Publication date: May 14, 2009Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Thomas Chyla, Volker Lehmann

Patent number: 4965419Abstract: A metal-clad, compressed gas-blast circuit-breaker having a gas-filled housing and an interrupter unit supported in the housing by a hollow post insulator. The circuit-breaker has a shifting linkage with at least one insulating drive rod, the shifting linkage transmitting the switching motion from a driving mechanism to a movable switching contact. In order to reduce the overall axial length of the circuit-breaker, the hollow post insulator comprising only insulating material, is penetrated only by the insulating drive rod and has, for fixing to the housing, on an end area facing away from the interrupter unit, on an outside surface, a premolded flanged ring mounted set back axially from the edge and being adapted to the bearing ring of the housing. The described circuit-breaker is esepcially suited for application in gas-insulated, metal-clad, high-voltage switching stations.Type: GrantFiled: January 18, 1990Date of Patent: October 23, 1990Assignee: Siemens AktiengesellschaftInventors: Thomas Chyla, Manfred Meinherz
