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: 7440259Abstract: A closure device for a withdrawable rack adapted for receiving power circuit breaker includes a plate arrangement having at least two plates provided with openings and movable relative to one another so that the plate arrangement is changeable between an open position in which the openings of the plates are in alignment and a closed position in which the openings are out of alignment. An actuating mechanism is acted upon by the power circuit breaker as it is inserted to cause a movement of at least one of the plates to thereby change the plate arrangement between the closed and open positions. The actuating mechanism includes two V-shaped linkage assemblies. Each linkage assembly has two legs connected by a hinge to allow the linkage assembly to spread apart, with one of the legs having a free end which is connected to the at least one of the plates, and a coupler is connected to the hinge. Both couplers are jointly articulated to actuating element.Type: GrantFiled: June 14, 2007Date of Patent: October 21, 2008Assignee: Siemens AktiengesellschaftInventors: Erhard Deylitz, Burkhard Engemann, Stefan Losch

Patent number: 7067747Abstract: A protective unit may prevent contact with conductive contacts in a withdrawable rack of a switching device. This may include one displaceable protective plate and lever arrangement for operating the protective plate. The lever arrangement has two levers that are interconnected in an articulated manner, of which a first lever can be operated by way of the switching device and the second lever is coupled to the mobile protective plate. A linking joint of the two levers acts simultaneously as the pivot bearing of the first lever and the first lever can be pivoted out of the displacement path of the switching device into an end position by way of a slide block that runs in a graded manner in the pivoting direction of the first lever.Type: GrantFiled: April 18, 2002Date of Patent: June 27, 2006Assignee: Siemens AktiengesellschaftInventors: Erhard Deylitz, Kathrina Marek

Patent number: 7067746Abstract: A travelling mechanism for a withdrawable circuit-breaker includes a crank handle that is secured in a manner that prevents it from being removed. A shaft of the crank handle revolves around an input shaft and is guided in a manner that permits it to be displaced in relation thereto. An accommodating recess holds the crank handle in its inoperative position. In its working position, the crank handle can only be pulled out when a locking lever that is dependent on the switching position of the circuit-breaker releases a locking slot on the shaft of the crank handle. In the working position, the crank handle is secured by a locking slide. An indicating device for indicating the position of the circuit-breaker comprises a two-armed indicating lever, which is provided with a window opening that permits the entry of a tongue of the locking slide in the test position.Type: GrantFiled: March 26, 2002Date of Patent: June 27, 2006Assignee: Siemens AktiengesellschaftInventor: Erhard Deylitz
