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.

摘要： The invention relates to a device for generating a reliable low-impedance electric short-circuit irrespectively of the operating voltage, comprising two electric connection parts (1, 2) which are plate-shaped in particular and which carry a different potential. An insulating section is formed between the connection parts, and the desired short-circuit is implemented by at least partly penetrating or destroying the insulating section. According to the invention, the connection parts are arranged closely adjacent to each other with the inclusion of the insulating section, and the insulating section is in the form of an insulating foil (4) or a foil-like coating. Furthermore, an exothermic mass (3) is located in the direct vicinity of the insulating section, and the mass releases exothermic energy when energy is applied and produces a melting or deformation of the insulating section such that the galvanic isolation between the connection parts (1, 2) is removed and the short-circuit event occurs.

摘要： The invention relates to a horn spark gap lightning arrestor with a deion chamber (6) for quenching arcs in a housing (1) and controlling the internal gas flow for adjusting a different response of the arc produced in the case of power pulse current loading, on the one hand, and of the arc induced by follow-on current, on the other hand. For this purpose, the distance between the opposite electrode faces of the horn spark gap in the striking region is kept very small and there is only a slight widening of the distance in the direction of the end of the horn spark gap in order to prevent undesired migration of the arc in the event of lightning pulse currents. Furthermore, gas circulation is provided such that the pressure wave produced by the lightning pulse current-induced arc is reflected by the deion chamber (6) and/or flow obstacles and counteracts the arc movement. A temporally delayed gas flow which passes through the deion chamber (6) is passed back at least partially to the striking region via deflection means and passed to flow openings provided in the electrodes in order to assist the arc movement (9) in the event of a follow-on current in the direction of the deion chamber (6), for which purpose the flow openings are located above the ignition region in the direction of the deion chamber (6).
