  • Switching-device tripping apparatus
    Patent number: 9548175
    Abstract: A switching-device tripping apparatus for a switching device includes contact pieces that can be moved relative to one another. Relative motion between the contact pieces is generated by a gear or transmission configuration. The gear or transmission configuration has a pawl in order to control motion of the contact pieces relative to each other. First and second tripping devices are provided, which work or operate the same pawl and drive the same pawl.
    Type: Grant
    Filed: November 15, 2012
    Date of Patent: January 17, 2017
    Assignee: Siemens Aktiengesellschaft
    Inventors: Oliver Duwe, Thomas Hilker
  • Current transformer arrangement
    Patent number: 8908337
    Abstract: A current transformer configuration includes a primary part and a secondary part. The primary part is surrounded by a housing. The housing has a first conductive housing part and a second conductive housing part. An electrically insulating gap lies between the two conductive housing parts. The housing passes through the secondary part. The electrically insulating gap is bridged by a surge protection configuration.
