Definitions

  • My invention relates to vacuum discharge vessels of metal and has for its particular object to improve the leading-in connections.
  • V The dangerous discharges occur especially at the places where the insulating material touches conducting portions, and the present invention aims to provide means for guarding against such. discharges.
  • this expedient is applied tothe insulator whereby thesealed leading-in lie entirely in the vacuum, and these must also be protected,ifthe introduction of the current shall be able to withstand higher tenmay become necessary to concentrate thedrop in potential instead of. one zone only, upon several narrow zones, which zones must be mutually separated'by spaces being a multiple of the width of the zone, since an eventual discharge in one zone must not interfere with U I the discharge tension in the others. Moreover, all said zones must have a sufficiently great distance from all the points of contact of the insulating material with the conducting parts, and these distances should be at least a multiple of the width of the zone.
  • G is the wall of the vacuum discharge vestor which carries the electric current and J the cylindrical insulator; Its surface where I it adjoins the vacuum is substantially covered by two metal projections F and F, forming with J a narrow gap W8. A similar gap is provided between F and F. Since F is electrically connected with the wall of the metal vessel and F with the electrode, the
  • the zone at V is moreover removed about a 10 multiple of its width from the points of contact X and X between, the insulator and the 3 conducting parts in the vacuum. Furthermore, by this arrangement, the insulatin'gmaterial .is protected. against the discharges which normally start from the active surface of'the electrode, for the particles of the charge must diffuse through the narrow gap VS, before they can reach the surface of the insulator.
  • the insulatorJ need not serve as a sealing 7 medium for the vacuum as shown in the draw- .ing, for it mightbe located entirely in the vacuum and be used, for example, as a mechanical support.
  • a vacuum discharge vessel of metal for -,containing a rarefied fluid the combination of an electrode, an insulator sealing said elec- -trode in said vessel and slightly spaced conducting parts covering a portion of the surface of said insulator within thevessel, one of saidparts being electrically connected with said vessel and another of said parts' with said electrode, said conducting parts forminganarrow gap in which the dropin potential between said vessel and saidelectrode is l to be concentrated, said gap being located from the points of contact of said insulator a and conducting parts in the vacuum at a dis- 4 tance forming a multiple of its width, the
