KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Wenn zwei Metallteile durch ein festes Dielektrikum voneinander getrennt sind, dann wird am Rande der Metalle das elektrische Feld in der Luft sehr groß sein, weil der dielektrische Widerstand des festen Materials bedeutend kleiner ist als derjenige der Luft, und weil daher die Kraftlinien in großer Zahl dem festen Material zu gebrochen werden. In dem Winkelraum zwischen dem Metall und dein festen Material ist daher die Beanspruchung sehr groß, und es werden daher hier leicht Glimmerscheinungen einsetzen.If two metal parts are separated from each other by a solid dielectric, then at the edge of the metals the electric field in the air will be very large because of the dielectric Resistance of the solid material is significantly smaller than that of the air, and therefore the lines of force in large numbers the solid material to be broken. In the angular space between the metal and Your solid material is therefore the stress very large, and therefore glowing phenomena will easily set in here.
Man kann diese Gefahr beseitigen, indem man dicht unter der Oberfläche eine metal-This danger can be eliminated by placing a metal sheet just below the surface.
1S lische Einlage in das Dielektrikum macht und diese Einlage mit der darüberliegenden Metallmasse verbindet. In der .beiliegenden Figur ist die erforderliche Anordnung im Schema wiedergegeben; α und b sind ,metallische Be-'läge des festen Dielektrikums e. In dieses ist die Einlage d gemacht, welche durch c mit b in Verbindung steht. Glimmerscheinungen, welche sonst schon sehr früh auftreten würden, werden jetzt erst bei einer sehr viel höheren Spannung möglich sein. Die Erfindung ist anwendbar bei allen Hochspannungsapparaten, z. B. Stützisolatoren, Durchführungen, Isolationsröhren für Transformatoren und Maschinen usw. Bei Durchführungen läßt sich besonders an den äußeren Fassungsringen jede Glimmerscheinung mit Hilfe des beschriebenen Verfahrens beseitigen. 1 S ical insert makes in the dielectric and connects this insert with the overlying metal mass. In the attached figure, the required arrangement is shown in the scheme; α and b are metallic coatings of the solid dielectric e. In this insert d is made, which is connected to b by c. Glimmer phenomena, which would otherwise appear very early, will only now be possible at a much higher voltage. The invention is applicable to all high voltage equipment, e.g. B. Post insulators, bushings, insulation tubes for transformers and machines, etc. In bushings, any glimmer can be eliminated with the help of the method described, especially on the outer mounting rings.
