摘要： Die Erfindung betrifft eine Überspannungsschutzeinrichtung auf Funkenstreckenbasis, insbesondere für Niederspannungs-Anwendungen, umfassend mindestens zwei in einem druckdichten Gehäuse befindliche Hauptelektroden sowie mindestens eine Zündhilfselektrode, wobei im Gehäusevolumen eine Funktionsbaugruppe zum Reduzieren der Ansprechspannung der Funkenstrecke untergebracht ist, welche mit einer der Hauptelektroden und der Zündhilfselektrode in Verbindung steht. Erfindungsgemäß besteht die Funktionsbaugruppe zum Reduzieren der Ansprechspannung der Funkenstrecke aus einer vollständig in das druckdichte Gehäuse integrierten, außerhalb des Lichtbogen-Brennraums befindlichen Reihenschaltung eines spannungsschaltenden Elements, einer Impedanz und einer Trennstrecke, wobei die Trennstrecke durch den Abstand der Zündhilfselektrode zur nächstliegenden Hauptelektrode gebildet ist. Beim Auftreten einer Überspannung, welche die Summe der Ansprechspannungen des Schaltelements und der Trennstrecke übersteigt, fließt ein Strom von der ersten Hauptelektrode zur zweiten Hauptelektrode, mit der Folge, dass der die Trennstrecke überbrückende Lichtbogen Ladungsträger zur sofortigen Ionisation der Trennstrecke zwischen den Hauptelektroden bereitstellt, wodurch die Spannungsfestigkeit dieser Trennstrecke veringert ist und aufgrund des mit der Stromstärke steigenden Spannungsabfalls an der Impedanz ein Überschreiten der reduzierten Spannungsfestigkeit der Trennstrecke zwischen den Hauptelektroden eintritt, wodurch das gewünschte Zünden der Funkenstrecke erfolgt.

摘要： The invention relates to a compact arrangement for multipole, surge-protected surge arresters, comprising internally wired, encapsulated series gaps which are arranged essentially in parallel in a housing. Said series gaps have opposite-lying, projecting contact surfaces which are connected to outer terminals and inner contact bars or bridges. The arrangement also comprises an electronic control or trigger circuit which is located on a wiring support. The housing is provided with dividing walls and has a trough shape, the resulting housing chambers accommodating the series gaps and the terminals. An insulating plate with openings into which spring contact elements are introduced is provided on the housing trough which opens upwards. Located above said insulating plate is the wiring. The spring contact elements create the electrical connection between contact points on the underside of the wiring support and the cover of one of the series gaps, respectively. The invention also relates to an encapsulated surge protector, comprising a series gap arrangement with two metallic main electrodes lying coaxially to each other and at least partially overlapping each other and having connections in opposite directions. Said main electrodes form an arc chamber in conjunction with at least one insulation part. According to the invention, at least one of the main electrodes has an inner expansion chamber and a trigger electrode extending preferably radially or axially rotationally symmetrically is provided at least in the area of an outer insulation part.
