  • Electric Switching Device for Medium- and/or High-Voltage Uses
    Publication number: 20240047159
    Abstract: Various teachings of the present disclosure include an electrical switching device. The device may include: two contactable conductor elements with adjustable spacing set by a movement apparatus; and a housing defining a switching chamber and at least partially surrounding the at least two conductor elements. The housing has an insulator body and regions of an electrical contact. The housing includes an external refraction-controlling coating with a dielectrically insulating matrix made of a material with a permittivity ?r>/=2.

  • Make contact system
    Patent number: 11462375
    Abstract: A make contact system for high-voltage applications includes a vacuum switching tube having two switch contacts in the form of plate contacts, of which at least one is a moving contact coupled to a drive. At least one plate contact is rotationally symmetrically surrounded by a shielding element, and the shielding element has an electric conductivity which is less than 40×10?6 S/m.

  • Vacuum interrupter and high-voltage switching assembly
    Patent number: 11456133
    Abstract: A vacuum interrupter includes a housing having at least one annular ceramic insulating element which forms a vacuum chamber. A contact system has two contacts which are movable relative to one another. A capacitive element has two electrodes and a dielectric material disposed between the electrodes. The capacitive element is form-lockingly mounted on the insulating element and has a capacitance between 400 pF and 4000 pF. A high-voltage switching assembly including the vacuum interrupter is also provided.
