Publication number: 20210193424Abstract: A restoring element is for an electrical switch. In an embodiment, the restoring element is constructed in two parts from a first part and a second part. The two parts are configured to converge in a first direction for tripping the electrical switch and the two parts do not necessarily converge in a second direction for resetting the electrical switch, the second direction being different from the first direction. Further, the second part of the restoring element includes a restoring cam which is configured to interact with a handle of a switching mechanism of the electrical switch, such that, during resetting of the electrical switch, the restoring element is configured to be rotated by the handle in the second direction for resetting the electrical switch.Type: ApplicationFiled: December 17, 2020Publication date: June 24, 2021Applicant: Siemens AktiengesellschaftInventors: Pawel BIEDUNKIEWICZ, Joerg-Uwe DAHL, Markus FALTERMEIER

Patent number: 10971316Abstract: A pressure trip unit for an electrical switch, including an actuating element and at least one flow channel per electrical pole, is disclosed. In an embodiment, the at least one pole of the electrical switch includes at least two switching contacts for making or disconnecting a flow path. The switching contacts of the at least one pole of the electrical switch are disconnectable via the actuating element which can respond to a pressure generated in a disconnection zone of the, in each case, two switching contacts by an electric arc drawn in the event of an electrodynamic recoil of the switching contacts. Further, the disconnection zone is connectable to the actuating element via the flow channel, the at least one flow channel including a nonreturn valve to permit a flow only from the disconnection zone in the direction of the actuating element.Type: GrantFiled: July 31, 2018Date of Patent: April 6, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Oliver Andersen, Pawel Biedunkiewicz, Joerg-uwe Dahl, Erhard Deylitz

Publication number: 20200219686Abstract: A trigger element includes an actuating member of a pressure trigger for an electric switch. The pressure trigger is provided with at least one flow channel per electric pole. The at least one pole of the electric switch includes at least two switch contacts for making or breaking a current path. The switch contacts of the at least one pole of the electric switch is disconnectable via the actuating member, which can respond to a pressure that is generated by an electric arc drawn during electrodynamic recoil of the switch contacts in a separation zone of the two switch contacts. The separation zone is connectable to the actuating member via the flow channel such that the actuating member is guided from a housing of the trigger element between a neutral position and a trigger position. After the trigger position has been reached, a relief of pressure vents the pressure trigger.Type: ApplicationFiled: July 30, 2018Publication date: July 9, 2020Applicant: Siemens AktiengesellschaftInventors: Joerg-uwe DAHL, Erhard DEYLITZ, Oliver ANDERSEN, Pawel BIEDUNKIEWICZ

Patent number: 9330859Abstract: A rotor is disclosed for an electric switch. In an embodiment, the rotor includes a rotor housing and a rotatably mounted contact link, which has two movable contacts. In an embodiment, by rotation of the rotor, the two movable contacts are configured to interact with two stationary contacts of an electric switch so as to close or open a circuit. Further, the rotatably mounted contact link is mounted movably in the rotor housing in a direction perpendicular to the direction of the contact link in its closing position.Type: GrantFiled: July 16, 2014Date of Patent: May 3, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Pawel Biedunkiewicz, Jörg-Uwe Dahl, Erhard Deylitz

Patent number: 9299518Abstract: A rotor for an electric switch is disclosed. In an embodiment, the rotor includes a rotor housing and a rotatably mounted contact bridge, which exhibits two movable contacts, wherein, by the rotation of the rotor, the two movable contacts can interact with two fixed contacts of an electric switch for closing or opening a circuit. The rotatably mounted contact bridge in the rotor housing is movably mounted in a direction perpendicular to the direction of the contact bridge in its closed position.Type: GrantFiled: August 26, 2013Date of Patent: March 29, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Pawel Biedunkiewicz, Jörg-Uwe Dahl, Christoph Weber

Patent number: 9293271Abstract: A switch apparatus includes at least two contact levers, arranged rotatably about a common rotation axis and arranged, at least sectionally, parallel to one another and spaced apart. The contact levers each have two contact lever arms including contact sections for respectively making contact with one fixed mating contact section of a power line element. The two first contact lever arms make contact with a first force transfer element, and the two second contact lever arms make contact with a second force transfer element for applying a spring force. At least one force transfer element has, in touching sections for touching the contact lever arms, a bulge which extends radially outwards, for the uniform transfer of the spring force to the contact lever arms. At least one holding element of the two holding elements may be configured to be movable relative to the power line elements via an articulated bearing.Type: GrantFiled: December 23, 2014Date of Patent: March 22, 2016Assignee: SIEMEND AKTIENGESELLSCHAFTInventors: Pawel Biedunkiewicz, Jörg-Uwe Dahl

Patent number: 9287061Abstract: A rotor is shown for an electromechanical switching device, includes: a rotor housing; two contact bridges having in each case two contact portions; an intermediate element disposed between the two contact bridges and mounted so as to be rotatable about a rotation axis; and first spring pins and second spring pins; first spring elements and second spring elements. In an embodiment, the spring pins, the spring elements, and the intermediate element are operationally connected, and at least one of the first and second spring pins is disposed on the intermediate element and/or on the contact bridges such that the spring pin by rotating the rotor is tiltable between the two states in relation to the rotation axis. An embodiment furthermore relates to an electromechanical switching device including the rotor.Type: GrantFiled: September 15, 2015Date of Patent: March 15, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Pawel Biedunkiewicz, Jörg-Uwe Dahl
