Publication number: 20210044183Abstract: A method for repairing solder joint leakages on a connection unit designed to feed cooling water into hollow metallic stator bars of a stator winding of an electrical machine, wherein the connecting device includes a metallic bar-receiving body with a passage opening in which the stator bars are inserted, aligned using metallic spacers and connected fluid-tightly to the bar-receiving body and to the spacers by substance bonding using a solder. The free ends of the stator bars terminate substantially flush with the free ends of the spacers and with an end face of the bar-receiving body. A cup-like metallic cover element surrounds and connects the free ends of the stator bars fluid-tightly to the bar-receiving body by substance bonding so as to form a cooling water chamber. A metallic cooling water line connection is provided on the cover element and connected fluid-tightly to the cooling water chamber.Type: ApplicationFiled: January 24, 2019Publication date: February 11, 2021Applicant: Siemens AktiengesellschaftInventors: Sebastian Blachny, Detlef Frerichs, Rene Höhner, Robert Koch, Michael Kretschmer, Markus Nalasko, Jürgen Weidner, Klaus Wunderlich

Patent number: 7285960Abstract: A device and a method for locating partial discharges in a conductor rod of a dynamo-electric machine are provided, the conductor rod being provided with an exterior electrical insulation. A first and a second sensor are embodied so as to detect a signal which is generated by the partial discharge and spreads along the conductor rod. The first and second sensor are disposed at a distance from each other on the conductor rod in order to emit a partial discharge output signal that represents a specific moment of detection. The partial discharge output signals of the first and second sensor are fed to an evaluation unit which is embodied so as to locate the partial discharge on the conductor rod.Type: GrantFiled: April 19, 2004Date of Patent: October 23, 2007Assignee: Siemens AktiengesellschaftInventors: Roland Koch, Jürgen Weidner

Patent number: 5917334Abstract: A method for decoupling a high-frequency error signal from a high-frequency electromagnetic field in a heavy electrical machine includes decoupling a high-frequency error signal with at least one temperature probe acting as an antenna and being associated with a stator carrying an electrical winding. In a heavy electrical machine having a stator carrying an electrical winding, an apparatus for decoupling a high-frequency error signal from a high-frequency electromagnetic field includes at least one temperature probe being disposed in the stator for generating a low-frequency temperature signal. The at least one temperature probe has connecting lines leading out of the stator. A diplexer decouples the error signal from the temperature signal. The diplexer has an input to which the connecting lines are connected, a first output at which the temperature signal is furnished, and a second output at which the error signal is furnished.Type: GrantFiled: March 22, 1995Date of Patent: June 29, 1999Assignee: Siemens AktiengesellschaftInventors: Peter Grunewald, Jurgen Weidner, Reinhold Koziel
