Description
Die Erfindung betrifft eine Ausblasschute für einen Überspannungsableiter, wobei die Ausblasschute mindestens einen Ausblasbereich mit einer Ausblasöffnung sowie mindestens einen durch eine Wand des Ausblasbereichs führenden Wasserablaufkanal aufweist. Die Erfindung betrifft ferner einen Überspannungsableiter mit mindestens einer Druckentlastungseinrichtung, insbesondere Überdrucksicherung, wobei der mindestens einen Druckentlastungseinrichtung jeweils mindestens eine Ausblasschute zugeordnet ist und jede der Ausblasschuten mindestens einen seitlich überstehenden Ausblasbereich aufweist. Die Erfindung betrifft zudem einen Überspannungsableiter mit mindestens einer solchen Ausblasschute.The invention relates to a Ausblasschute for a surge arrester, wherein the Ausblasschute has at least one blow-out area with a blow-out and at least one leading through a wall of the blow-out water drainage channel. The invention further relates to a surge arrester having at least one pressure relief device, in particular overpressure protection, wherein the at least one pressure relief device is assigned in each case at least one Ausblasschute and each of the Ausblasschuten has at least one laterally projecting blow-out.

Es ist die Aufgabe der vorliegenden Erfindung, eine Möglichkeit zur preiswerteren Herstellung von mit einer Ausblasschute ausgerüsteten Hochspannungsableitern bereitzustellen.It is the object of the present invention to provide a possibility for the cheaper production of equipped with a Ausschwschute high voltage arresters.
Diese Aufgabe wird gemäß den Merkmalen der unabhängigen Ansprüche gelöst. Bevorzugte Ausführungsformen sind insbesondere den abhängigen Ansprüchen entnehmbar.This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.
Diese Aufgabe wird gelöst durch eine Ausblasschute für einen Überspannungsableiter, wobei die Ausblasschute mindestens einen Ausblasbereich mit einer Ausblasöffnung aufweist, wobei die Ausblasschute mindestens einen durch eine Wand des Ausblasbereichs führenden Wasserablaufkanal aufweist und wobei der Wasserablaufkanal an einer der Ausblasöffnung abgewandten Seite einen von der Wand hochstehenden Kragen ("äußeren Kragen") aufweist. Eine solche Ausblasschute ist zur Verwendung sowohl als eine obere Ausblasschute als auch als eine untere Ausblasschute geeignet. Bei einer Verwendung als untere Ausblasschute kann in den Ausblasbereich eindringendes Regenwasser durch den Wasserablaufkanal abfließen. Bei einer Verwendung als obere Ausblasschute kann Regenwasser nur in geringer Menge durch den Wasserablaufkanal in den Ausblasbereich gelangen. Diese bereits geringe Menge des einfließenden Regenwassers wird durch den hochstehenden Kragen weiter verringert, welcher verhindert, dass an der der Ausblasöffnung abgewandten Seite herabfließendes Regenwasser in den Wasserablaufkanal gelangt. Insgesamt kann sowohl bei einer Verwendung als obere Ausblasschute als auch als untere Ausblasschute eine Menge von sich über die Ausblasschute an dem Überspannungsableiter sammelnden Wassers auf einer unkritischen Menge gehalten werden. Folglich kann diese Ausblasschute für Überspannungsableiter sowohl als obere Ausblasschute als auch als untere Ausblasschute verwendet und folglich in größeren Mengen und preiswerter hergestellt werden. Ferner können damit ausgerüstete Überspannungsableiter einfacher sowohl hängend als auch stehend montiert werden.This object is achieved by a Ausblasschute for a surge arrester, wherein the Ausblasschute has at least one leading through a wall of the Ausblasbereichs water drainage channel and wherein the water outlet channel at one of the exhaust opening facing away from the wall of at least one blowout with a blowout Collar ("outer collar") has. Such a discharge baffle is suitable for use both as an upper discharge baffle and as a lower discharge baffle. When used as a lower Ausblasschute rainwater entering the blow-out area can flow through the water drainage channel. When used as the upper Ausblasschute rainwater can pass only in a small amount through the water drainage channel in the Ausblasbereich. This already small amount of the inflowing rainwater is further reduced by the upstanding collar, which prevents rainwater flowing down the side of the discharge opening from entering the water drainage channel. Overall, both when used as the upper Ausblasschute as well as lower Ausblasschute a lot of about the Ausblasschute to the surge arrester collecting water can be maintained at a non-critical amount. Consequently, this outlet bar for surge arresters used both as upper Ausblasschute as well as lower Ausblasschute and consequently produced in larger quantities and cheaper. Furthermore, surge arresters equipped with them can be mounted more easily both suspended and upright.
Die Ausblasschute kann insbesondere mindestens einer Druckentlastungseinrichtung des Überspannungsableiters zugeordnet sein oder eine solche darstellen.The Ausblasschute may in particular be associated with at least one pressure relief device of the surge arrester or represent such.
Die Ausblasschute kann auch als eine Ausblasblende bezeichnet werden. Unter einem Ausblasbereich kann insbesondere ein Bereich oder Kanal verstanden werden, durch welchen die heißen Gase laufen oder geleitet werden.The exhaust barge can also be referred to as a blowout. A blow-off region may, in particular, be understood as meaning an area or channel through which the hot gases pass or pass.
Es ist eine Ausgestaltung, dass der Wasserablaufkanal der Ausblasöffnung gegenüberliegt. So kann bei einer Verwendung als oberer Ausblasschute das durch den Wasserablaufkanal eindringende Wasser abtropfen und direkt durch die Ausblasöffnung heraustropfen. So kann ein Sammeln von Wasser in dem Überspannungsableiter im Wesentlichen verhindert werden.It is an embodiment that the water drainage channel is opposite to the blowout opening. Thus, when used as the upper Ausblasschute the water penetrating through the water drainage channel drip off and drip directly through the discharge opening. Thus, accumulation of water in the surge arrester can be substantially prevented.
Es ist noch eine Ausgestaltung, dass der Wasserablaufkanal an einer der Ausblasöffnung zugewandten Seite zumindest abschnittsweise einen hochstehenden Kragen ("inneren Kragen") aufweist. So kann verhindert werden, dass das an der der Ausblasöffnung zugewandten Seite aus dem Wasserablaufkanal austretende Wasser nicht abtropft, sondern an der Wand des Ausblasbereichs herunterläuft. Der innere Kragen kann auch als ein Ausgießer bezeichnet werden.It is still an embodiment that the water drain channel at least one section of the water outlet channel facing an outlet opening has an upstanding collar ("inner collar"). Thus, it can be prevented that the water emerging from the water drain passage at the side facing the blow-off opening does not drip off, but runs down the wall of the blow-off area. The inner collar may also be referred to as a spout.
Es ist eine spezielle Ausgestaltung, dass der innere Kragen teilweise abgesenkt ist. So kann bei einer Verwendung als untere Ausblasschute ein maximal möglicher Wasserpegel in dem Ausblasbereich abgesenkt werden, insbesondere falls der innere Kragen teilweise im Wesentlichen bis auf eine Höhe der umgebenden Wand abgesenkt ist.It is a special embodiment that the inner collar is partially lowered. Thus, when used as a lower Ausblasschute a maximum possible water level can be lowered in the discharge area, in particular if the inner collar is partially lowered substantially substantially to a height of the surrounding wall.
Es ist eine Weiterbildung, dass der innere Kragen in Richtung eines die Ausblasöffnung begrenzenden freien Rands des Ausblasbereichs hin abgesenkt ist, so dass bei Verwendung als untere Ausblasschute in den inneren Kragen herablaufendes Wasser direkt auch den Wasserablaufkanal abfließen kann. Dies gilt insbesondere, falls der innere Kragen in Richtung des freien Rands hin im Wesentlichen bis auf eine Höhe der umgebenden Wand abgesenkt ist.It is a further development that the inner collar is lowered in the direction of a free edge of the blow-out area bounding the blow-out opening, so that water which drains into the inner collar when used as a lower blow-off bar can also directly drain off the water drainage channel. This applies in particular if the inner collar is lowered in the direction of the free edge substantially to a height of the surrounding wall.
Es ist außerdem eine Ausgestaltung, dass der Ausblasbereich einen umgebogenen Seitenrand aufweist bzw. zumindest teilweise aus einem umgebogenen Seitenrand der Ausblasschute gebildet ist. Insbesondere kann ein freier Rand des Seitenrands zumindest abschnittsweise den freien Rand des Ausblasbereichs bilden. So kann der Ausblasbereich auf eine einfache und besonders betriebssichere Weise bereitgestellt werden.It is also an embodiment that the blow-out has a bent side edge or at least partially formed of a bent side edge of the blow-out. In particular, a free edge of the side edge can at least partially form the free edge of the blow-off region. Thus, the blow-out area can be provided in a simple and highly reliable manner.
Es ist ferner eine Ausgestaltung, dass die Ausblasschute einen (insbesondere in Bezug auf eine Längsachse der Ausblasschute entlang einer Umfangsrichtung) umlaufenden Ausblasbereich aufweist.It is also an embodiment that the Ausblasschute has a (in particular with respect to a longitudinal axis of the Ausblasschute along a circumferential direction) circulating exhaust area.
Alternativ kann die Ausblasschute mehrere, in einer Umfangsrichtung beabstandete, Ausblasbereiche aufweisen. Diese können insbesondere in einer drehsymmetrischen Anordnung um die Längsachse der Ausblasschute angeordnet sein.Alternatively, the Ausblasschute having a plurality of spaced apart in a circumferential direction, Ausblasbereiche. These can be arranged in particular in a rotationally symmetrical arrangement about the longitudinal axis of the Ausblasschute.
Die Aufgabe wird auch gelöst durch einen Überspannungsableiter, welcher mindestens eine Ausblasschute wie oben beschrieben aufweist.The object is also achieved by a surge arrester which has at least one exhaust bar as described above.
Der Überspannungsableiter kann insbesondere endständig mit der mindestens einen Ausblasschute ausgerüstet sein. Der Überspannungsableiter kann insbesondere einseitig oder zweiseitig mit jeweils einer Ausblasschute ausgerüstet sein. Die Druckentlastungseinrichtung kann insbesondere eine Überdrucksicherung sein. Der Überspannungsableiter kann insbesondere ein Hochspannungsableiter oder ein Mittelspannungsableiter sein. Die Druckentlastungseinrichtung kann insbesondere eine Membran aufweisen.The surge arrester may in particular be equipped terminally with the at least one exhaust barge. The surge arrester may in particular be equipped on one or two sides with a respective Ausblasschute. The pressure relief device may in particular be an overpressure safety device. The surge arrester can in particular be a high-voltage arrester or a medium-voltage arrester be. The pressure relief device may in particular comprise a membrane.
Es ist eine Ausgestaltung, dass der mindestens einen Druckentlastungseinrichtung jeweils mindestens eine Ausblasschute zugeordnet ist und der mindestens eine Wasserablaufkanal seitlich (bezüglich der Längsachse) der Druckentlastungseinrichtung angeordnet ist. So kann verhindert werden, dass durch den Wasserablaufkanal Wasser direkt auf die Druckentlastungseinrichtung tropft.It is an embodiment that the at least one pressure relief device is assigned in each case at least one Ausblasschute and the at least one water drainage channel is arranged laterally (with respect to the longitudinal axis) of the pressure relief device. This can prevent water from dripping directly onto the pressure relief device through the water drainage channel.

Die Membran 18 liegt senkrecht und konzentrisch zu der Längsachse L und deckt einen hohlen Innenraum des Hochspannungsableiters 2 unmittelbar ab. Die drei Auflagebereiche 17 sind zueinander beabstandet, so dass in einem Überspannungsfall in dem Hochspannungsableiter 2 gebildetes heißes Gas zunächst seitlich durch Lücken 19 zwischen den Auflagebereichen 17 strömt.The Ausblasschute 1 has on its inner side 4 three upstanding, around the longitudinal axis L ring sector shaped and arranged support areas (mounting webs) 17 for a pressure relief device in the form of a
Die Ausblasschute 1 weist mindestens einen Ausblasbereich 6 mit einer Ausblasöffnung 7 auf.
