Patents by Inventor Joerg Kusserow

Joerg Kusserow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for opening the contact gap of a vacuum interrupter
    Patent number: 7334319
    Abstract: The aim of the invention is to improve the breaking ability of vacuum interrupter in the medium- and high-voltage range. Said aim is achieved whereby the contact pieces which may be displaced relative to each other are moved with a relatively high speed during a first phase (S1) of the separation process until about ¼ to ½ of the ultimate separation (extinction stroke Eh) and are brought to the given ultimate separation (isolating stroke Eh) during a second phase (S2) with relatively low speed.
    Type: Grant
    Filed: June 6, 2001
    Date of Patent: February 26, 2008
    Assignee: Siemens Aktiengesellschaft
    Inventors: Joerg Kusserow, Roman Renz
  • Vacuum interrupter chamber with ring-shaped insulator
    Patent number: 6864456
    Abstract: A new vacuum switching chamber is intended for power breakers in the low-voltage range and is distinguished by a compact form with a small physical height and a high switching capacity. Its enclosure includes a plate-like power current connection, a cylindrical wall part which surrounds flat spiral contacts, an annular insulator and a membrane disk with a centrally arranged power current supply bolt.

  • Vacuum switching chamber having an annular insulator
    Patent number: 6417472
    Abstract: A vacuum switching chamber is provided for power switches in the low-voltage range, and has compact design and a high switching capacity. A housing of the switching chamber includes plate-type current terminals, a cylindrical wall part that surrounds flat spiral petal contacts, an annular insulator and a bellows arranged concentrically thereto. The current terminal bolt of the movable spiral petal contact is seated on the associated plate-type current terminal.

  • Vacuum switch
    Patent number: 5313030
    Abstract: A vacuum switching tube has a cylindrical housing, including an insulator which directly surrounds contact pieces of the tube. The radial distance of the insulator from the contact pieces is less than or at most equal to the length of the contact stroke. In addition, the contact pieces can be structured as axial magnetic field contacts, and the free cross-section can be narrowed in the back space of the contact pieces by radial expansion at the contact pins or by radial constriction of the insulator.
