Patent 10777973 - Arrangement of stack spark gaps and device for holding together and electrically contacting stack spark gaps > Claims

  • 1. An arrangement of stack spark gaps, comprising: a plurality of stack spark gaps each of which has multiple electrodes,insulating elements that are arranged between the electrodes,a first electrically conductive clamping element and a second electrically conductive clamping element, the two clamping elements being arranged opposite to one another at front ends of the stack spark gaps,at least one connecting element, by which the two clamping elements are connected to one another, andconnection elements for electrical connection to the stack spark gaps,wherein three stack spark gaps are arranged beside one another between the two clamping elements,wherein the at least one connecting element is electrically conductive, and the two clamping elements are connected to one another electrically via the at least one connecting element,wherein each stack spark gap has one of its front ends used as a connection side and is connected to one of the connection elements in an electrically conductive manner,wherein an insulator is arranged between the connection side of each stack spark gap and the one of the two clamping elements that is arranged on the connection side, in such a way that the connection side of each stack spark gap is insulated electrically from the clamping element, andwherein the front end of each stack spark gap that is opposite to the connection side is connected in an electrically conductive manner to the clamping element that is arranged at that end in such a way that the three stack spark gaps form a star circuit.
    • 2. The arrangement according to claim 1, wherein the stack spark gaps are arranged in such a way that the connection sides of two of the stack spark gaps face the first clamping element, and the connection side of a third of the stack spark gaps faces the second clamping element.
      • 3. The arrangement according to claim 2, wherein first and second insulating elements are arranged on the sides of the clamping elements that face the front ends, wherein a recess is formed in the first insulating element through which a front end of one of the stack spark gaps is connected to the first clamping element, and wherein two recesses are formed in the second insulating element, through which the front ends of the two other stack spark gaps are connected to the second clamping element.
        • 4. The arrangement according to claim 3, wherein the insulating elements are frame-shaped, and wherein an outside contour of the insulating elements is matched to an outside contour of the clamping elements, and where the insulating elements project at least partially beyond the clamping elements.
    • 5. The arrangement according to claim 1, wherein a contact element is arranged between each of the front ends of the stack spark gaps that are connected to the clamping elements in an electrically conductive manner and the clamping elements, and each contact element being connected to an adjoining electrode of the respective one of the stack spark gaps in an electrically conductive manner.
    • 6. The arrangement according to claim 1, wherein each of the connection elements has a contact area and a connection area and each connection element is connected via the contact area to an adjoining electrode of a respective one of the stack spark gaps in an electrically conductive manner.
      • 7. The arrangement according to claim 6, wherein the connection area of the connection elements is guided through a respective corresponding opening in the insulator, on a side of the clamping elements that faces away from the stack spark gap, without contacting the clamping elements.
    • 8. Arrangement according to claim 1, wherein the two clamping elements are electrically connected to one another via multiple connecting elements.
    • 9. Arrangement according to claim 1, wherein the at least one connecting element is designed as a screw or bolt and wherein recesses are formed in the clamping elements through which the at least one connecting element at least partially extends.
