摘要:
Ein Gasentladungsüberspannungsableiter, der ein rohrförmiges, isolierendes Gehäuse (1), zwei in dessen Enden gasdicht eingesetzte Elektroden (2, 3), die einen Funkenstreckenspalt (6) zwischen sich freilassen, aufweist. Als Zündhilfen sind auf die Innenwand des Gehäuses (1) parallel zur Achse des Gehäuses (1) Linien (7, 8) aus elektrisch leitfähigem Material angebracht, die bei einer bevorzugten Ausführungsform abwechselnd mit der einen (2) oder der anderen Elektrode (3) verbunden sind. Zwischen den Linien (7, 8) aus elektrisch leitfähigem Material sind zur Verbesserung der Lebensdauer ohne Beeinträchtigung des Isolationswiderstandes jeweils mindestens eine Nut (12) oder mindestens eine leistenförmige Erhebung (13) angebracht, die durch einen Abschattungseffekt bewirken, daß sich an bestimmten Bereichen auf der Innenwand des Gehäuses (1) von den Elektroden verdampfendes Material nicht abscheidet.
摘要:
In einer Funkenstrecke in einem gasgefüllten Gehäuse (1) wird eine hohe Zündspannung mit einer geringen Verlustleistung erreicht, indem ein Gasdruck von zumindest 5 bar im Gehäuse (1) erzeugt wird und indem die Stirnftächen (8) der Elektroden (2) in geringem Abstand voneinander angeordnet sind. Die Erfindung wird vorzugsweise für Vorfunkenstrecken in Otto-Motoren eingesetzt.
摘要:
To provide a discharge tube having improved stability of operating voltage to repeated discharges. The discharge tube includes a cylindrical insulating hollow body 2 having openings at least at both ends and at least a pair of sealing electrodes 3 facing to each other for closing the openings so as to seal a discharge control gas inside the body, wherein a discharge trigger film 4 made of a conductive material is formed on the inner circumferential surface of the insulating hollow body, each of the sealing electrodes has a convex portion 3a projecting into the insulating hollow body and a discharge active layer(s) 5 that is/are made of a material having higher electron emission characteristics than that of the sealing electrodes and formed at the apical end of the convex portion, the discharge active layer(s) is/are formed at the apical end of the convex portion and near the outer periphery edge of the apical surface as a plurality of layers or a continuously extending single layer along the outer periphery edge, and the central part of the apical surface of the convex portion is a region where the discharge active layer is not formed.
