Patents by Inventor Holger Schumann

Holger Schumann 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).

  • Patent number: 12159763
    Abstract: A vacuum switch device has a housing body, a stationary electrical contact and a moving electrical contact, which is arranged within the housing body. With a movement of the moving contact towards the stationary contact, the contacts form an electrical contact. With a movement away the electrical contact is interrupted. A sliding bearing provides sliding support for the moving contact for its movement towards and away from the stationary contact. The sliding bearing has an electrically conductive material and at least partially electrically insulates the housing body. A spring element is supported on a spring support and presses the moving electrical contact in the direction of the stationary electrical contact. There is also provided a circuit with a main current path and a parallel auxiliary current path. The vacuum switch device is arranged in the auxiliary current path.

  • Patent number: 7019228
    Abstract: The invention relates to a method for controlling an electrical switching module which can be displaced between an entry position and an exit position. The switching module comprises switching contacts of vacuum switching tubes; an isolating element which can be also be displaced in the switching module and comprises isolating contacts which can be connected to, and disconnected from, corresponding mating contacts inside an enclosed switchboard section, as required; and connector contacts and mating connector contacts in the low voltage range. The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating position.

The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating element are represented by an “operating position” and by an isolating position.
