Abstract
Description
Die Erfindung betrifft eine Lichtbogenlöschblechanordnung nach dem Oberbegriff des Anspruches 1.The invention relates to an arc extinguishing plate arrangement according to the preamble of Claim 1.
Eine solche Lichtbogenlöschblechanordnung, auch Lichtbogenlöschblechpaket genannt, ist in einem Leitungsschutzschalter oder einem Motorschutzschalter untergebracht. Das Lichtbogenlöschblechpaket setzt sich zusammen aus mehreren Lichtbogenlöschblechen, die identisch ausgebildet sind. Die Bleche sind rechteckig und bestehen aus Metall und besitzen eine V-förmige Einlaufkontur, die zur Lichtbogenentstehungsstelle offen ist. Die einzelnen Löschbleche werden mittels beidseitig an ihren Längsseiten angeordneter Streifen aus Isoliermaterial zum Paket zusammen gehalten und auf gegenseitigen Abstand eingestellt.Such an arc-quenching plate arrangement, also called an arc-quenching plate package, is housed in a circuit breaker or a motor protection switch. The Arc quenching plate package consists of several arc quenching plates, which are identical. The sheets are rectangular and are made of metal and have a V-shaped inlet contour that is open to the point of arcing. The Individual quenching plates are arranged on both sides on their long sides Strips of insulating material held together to the package and at a mutual distance set.
Wenn nun ein Lichtbogen zwischen einem beweglichen Kontaktstück und einem feststehenden Kontaktstück beispielsweise bei einem Kurzschlussstrom gezogen wird, so wird der Lichtbogen über Lichtbogenleitschienen, die den Löschblechstapel beidseitig in Stapelrichtung begrenzen, in das Lichtbogenlöschblechpaket geführt und dort in Teillichtbögen unterteilt, wodurch die Lichtbogenspannung erhöht und der Kurzschlussstrom dadurch begrenzt werden. Solche Lichtbogenlöschblechpakete sind z.B. aus der DE 36 30 447 bekannt geworden. Dabei grenzt das Lichtbogenlöschblechpaket in seinem in Lichtbogenlaufrichtung gesehen hinteren Ende an eine Wand aus Isoliermaterial, die Rillen aufweist, in die Hinterkanten der Löschbleche eingreifen.If there is an arc between a movable contact piece and a stationary one Contact piece is pulled for example in the event of a short-circuit current, so the arc is guided over by arc guide rails, which hold the stack of quenching plates on both sides Limit stacking direction, lead into the arc quenching plate package and there in partial arcs divided, which increases the arc voltage and the short-circuit current thereby be limited. Such arc quenching plate packages are e.g. from the DE 36 30 447 become known. The arc quenching plate package borders in its viewed in the direction of arc running, the rear end to a wall made of insulating material, has the grooves, engage in the rear edges of the quenching plates.
Darüber hinaus ist bekannt, siehe EP 0 617 836, hinter der Lichtbogenlöschkammer bzw. hinter dem Lichtbogenlöschblechpaket Rippen und Vorsprünge aus Isolierstoff anzuordnen, die eine zusätzliche Kühlung der Lichtbogengase bewirken sollen.It is also known, see EP 0 617 836, behind the arc quenching chamber or ribs and protrusions made of insulating material behind the arc quenching plate package to arrange, which should cause additional cooling of the arc gases.
Die maximal mögliche Löschblechanzahl ist dabei durch die Einbauhöhe bestimmt, wobei die Löschblechdicke und der Abstand zwischen den Blechen Einfluss hat. Da die Einbauhöhe und die maximal mögliche Löschblechanzahl verantwortlich ist für die Größe der resultierenden Lichtbogenspannung und damit für die mögliche Begrenzung des Kurzschlussstromes beim Einlauf des Lichtbogens in diese Löschkammer, ist man bestrebt, möglichst viele Lichtbogenlöschbleche in einer Lichtbogenlöschkammer unterzubringen, wobei in der Praxis eine Blechdicke von 0,6mm aufgrund der thermischen Festigkeit und ein Abstand der Bleche untereinander von 0,6mm nicht unterschritten werden kann und eine Unterschreitung dieser Werte auch nicht zur Erhöhung der Lichtbogenspannung führt. Damit ist aus diesen physikalischen Gründen für eine bestimmte Einbauhöhe die maximal erreichbare Lichtbogenspannung geometrisch festgelegt.The maximum possible number of fire extinguishing plates is determined by the installation height, whereby the sheet thickness and the distance between the sheets has an influence. Since the Installation height and the maximum possible number of fire extinguishing plates is responsible for the size the resulting arc voltage and thus for the possible limitation of the Short-circuit current when the arc enters this quenching chamber, one tries to to place as many arc quenching plates as possible in an arc quenching chamber, in practice a sheet thickness of 0.6mm due to the thermal strength and the distance between the sheets should not be less than 0.6mm can and does not fall below these values to increase the arc voltage leads. So for these physical reasons, it is for a certain Installation height geometrically defines the maximum achievable arc voltage.
Aufgabe der Erfindung ist es, bei gleichen geometrischen Abmessungen, d. h. bei gleicher Einbauhöhe des Löschblechpaketes eine höhere Lichtbogenspannung und damit eine bessere Begrenzung des Kurzschlussstromes zu erreichen.The object of the invention is, with the same geometric dimensions, i. H. at the same Installation height of the quenching plate package a higher arc voltage and thus to achieve a better limitation of the short-circuit current.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.
Danach besitzt das Lichtbogenlöschblechpaket erste Lichtbogenlöschbleche einer ersten Länge und zweite Lichtbogenlöschbleche einer gegenüber der Ersten kürzeren zweiten Länge; die Lichtbogenlöschbleche mit kürzerer Länge sind jeweils zwischen zwei Blechen der ersten Länge angeordnet, wobei die Hinterkanten beider Löschblechpakete parallel zueinander in einer senkrecht zur Lichtbogenlaufrichtung verlaufenden Ebene liegen.The arc-quenching plate package then has first arc-quenching plates from a first one Length and second arc quenching plates one shorter than the first second length; the shorter length arc quenching plates are each between two sheets of the first length arranged, the rear edges of both quenching sheet packages parallel to each other in a direction perpendicular to the arc running direction Level.
Im Folgenden soll das Lichtbogenlöschblech mit einer ersten Länge als erstes Blech und das Lichtbogenlöschblech mit der zweiten Länge als zweites Blech bezeichnet werden.In the following, the arc extinguishing plate with a first length should be the first plate and the arc extinguishing plate with the second length is referred to as the second plate become.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die ersten Löschbleche mittels zweier Streifen aus Isoliermaterial zu einem ersten Lichtbogenlöschblechpaket zusammengesetzt und die zweiten Bleche mittels weiterer Streifen aus Isoliermaterial zu einem zweiten Lichtbogenlöschblechpaket zusammen gesetzt. Beide Lichtbogenlöschblechstapel oder -pakete werden so ineinander gefügt, dass der Stapel mit den zweiten Löschblechen von hinten in den ersten Stapel eingefügt wird, wobei nach dem Einschieben der beiden Pakete ineinander Mittel vorgesehen sind, um die ersten und zweiten Löschbleche auf Abstand zu halten und gegeneinander zu positionieren.According to an advantageous embodiment of the invention, the first extinguishing plates are by means of two strips of insulating material to a first arc quenching plate package assembled and the second sheets by means of further strips of insulating material put together to a second arc quenching plate package. Both stacks of arc extinguishers or packages are put together so that the stack with the second quenching plate is inserted from behind into the first stack, after the Inserting the two packages into each other means are provided to the first and keep the second baffle plates at a distance and position them against each other.
Die ersten Bleche verlaufen über die gesamte Länge der Lichtbogenlöschkammer bzw. des Löschblechpaketes, während die eingeschobenen zweiten Bleche etwa zwischen 30% bis 50% dieser Länge messen. Beide Löschbleche weisen eine ähnliche V-förmige Einlaufkontur auf.The first sheets run the entire length of the arc quenching chamber or of the quenching sheet stack, while the inserted second sheets approximately between Measure 30% to 50% of this length. Both quenching plates have a similar V-shaped Inlet contour on.
Gegebenenfalls können die kurzen Löschbleche eine Dicke aufweisen, die gleich oder geringfügig geringer ist als die der ersten Löschbleche.If necessary, the short quenching plates can have a thickness equal to or is slightly less than that of the first quenching plates.
Zur Fixierung der beiden Lichtbogenlöschblechpakete gegeneinander besitzen die Streifen aus Isoliermaterial für das zweite Lichtbogenlöschblechpaket an ihrer zur Lichtbogenentstehungsstelle hinweisenden Kante Aussparungen, in die an den Lichtbogenlöschblechen des ersten Lichtbogenlöschblechpaketes angeformte Querkanten eingreifen; eine weitere Fixierung erfolgt dann durch Anformungen am an den Innenwänden des Schaltergehäuses, zwischen denen sich das zweite Lichtbogenlöschblechpaket befindet.To fix the two arc quenching plate packs against each other Strips of insulating material for the second arc quenching plate package at their point of arc formation indicative edge cut-outs in the arc-quenching plates engage the formed transverse edges of the first arc-quenching plate package; A further fixation is then carried out by forming on the inner walls of the switch housing, between which there is the second arc quenching plate package located.
Die Wirkungsweise dieser Anordnung ist wie folgt: This arrangement works as follows:
Zunächst läuft der Lichtbogen in den ersten Löschblechstapel ein, bei dem die einzelnen Bleche einen großen Abstand besitzen; dieses Einlaufen erfolgt schneller als bei den üblichen Löschblechpaketen, weil der Abstand zwischen zwei Löschblechen größer ist als der Abstand in Lichtbogenlöschblechpaketen gemäß dem Stand der Technik. Aufgrund des größeren Löschblechabstandes im vorderen Bereich ist auch der Strömungswiderstand vor dem Lichtbogen geringer, wodurch sich die Einlaufgeschwindigkeit vergrößert. Damit wird bereits im vorderen Paketbereich eine gute Strombegrenzung durch die der treibenden Spannung entgegengerichtete, schnell ansteigende Lichtbogenspannung erreicht. Der Lichtbogen wird dabei gekühlt und der Kurzschlussstrom sinkt. Bei Auftreffen des Lichtbogens auf den zweiten Stapel im hinteren Bereich des Lichtbogenlöschblechpaketes erfolgt eine nochmalige Unterteilung der Teillichtbögen in fast die doppelte Anzahl, wodurch die Lichtbogenspannung auf einen Wert weit über der treibenden Netzspannung ansteigt und der Lichtbogen schlagartig zum Verlöschen gebracht wird. Dadurch wird auch die thermische Belastung der im hinteren Bereich eingeschobenen, gegebenenfalls dünneren Bleche ausreichend gering gehalten.First, the arc runs into the first stack of quenching sheets, in which the individual Have a large distance between the sheets; this shrinkage is faster than at the usual quenching plate packages because the distance between two quenching plates is larger is as the distance in arc stack according to the prior art. Due to the larger distance between the fire extinguishers in the front area there is also the flow resistance in front of the arc lower, which reduces the infeed speed increased. This means that there is already a good current limitation in the front of the package due to the fast increasing direction of the driving tension Arc voltage reached. The arc is cooled and the short-circuit current sinks. When the arc strikes the second stack in the rear area of the arc quenching plate package, the partial arcs are subdivided again in almost double the number, bringing the arc voltage to a value far rises above the driving mains voltage and the arc suddenly extinguishes brought. This also reduces the thermal load in the rear area inserted, possibly thinner sheets kept sufficiently low.

Es sei nun Bezug auf die Fig. 3. Der dort dargestellte Lichtbogenlöschblechstapel 10
weist erste Lichtbogenlöschbleche 11 und zweite Lichtbogenlöschbleche 12 auf. Die
Lichtbogenlöschbleche 11 sind langgestreckt rechteckig und besitzen in üblicher Weise
in ihrem vorderen Bereich einen V-förmigen Ausschnitt 6, der als Einlaufaussparung
bezeichnet sein kann. Die einzelnen Lichtbogenlöschbleche 11 besitzen eine erste
Länge L1 und nehmen einen ersten Abstand D1 voneinander ein. Die ersten Löschbleche
11 sind mittels beidseitig angeordneter Streifen 14 und 15 aus isolierendem Material,
vorzugsweise aus Isolierpapier, auf Abstand zueinander gehalten. Dabei weist jedes
Löschblech 11 an seiner längeren Längskante Aussparungen 16, 17 auf, in denen sich
quer zur Längserstreckung der ersten Bleche vorspringende Zapfen 18, 19, 20 befinden,
wobei bei einem Löschblech beidseitig je zwei Zapfen 18 und 19 und bei dem benachbarten
Löschblech beidseitig je ein Zapfen 20 angeformt sind; Löschbleche mit je
zwei Zapfen wechseln somit mit Löschblechen mit je einem Zapfen ab.Reference is now made to FIG. 3. The stack of
In diesen ersten Stapel mit den ersten Löschblechen 11 ist ein zweiter Stapel mit zweiten
Löschblechen 12 eingefügt, die den gleichen Abstand D1 voneinander besitzen, gegebenenfalls
aber geringfügig dünner sind als die Bleche 11 des ersten Stapels. Diese
Lichtbogenlöschbleche 12 besitzen in ihrem vorderen Bereich ebenfalls einen V-förmigen
Ausschnitt 5 als Einlaufaussparung und auf ihren parallel zur Lichtbogenlaufrichtung
verlaufenden Kanten zwei quer dazu vorspringende Zapfen 22, 23, die in daran
angepasste Öffnungen je eines weiteren Streifens 24 aus elektrisch isolierendem Material,
vorzugsweise aus Isolierpapier eingreifen, so dass die Löschbleche in gleicher
Weise wie die Löschbleche 11 auf Abstand zueinander gehalten sind, wobei hier nur ein
Streifen 24 dargestellt ist.In this first stack with the
Wie aus Fig. 2 ersichtlich ist, ist die Länge a der ersten Bleche 11 größer als die Länge
b der zweiten Löschbleche 12, wobei die Länge b zwischen 30% bis 50% der Länge a
beträgt.As can be seen from Fig. 2, the length a of the
Aus Fig. 1 ist ersichtlich, dass an den in Lichtbogenlaufrichtung vorderen Längskanten
der beiden Streifen 24 nutenartige Aussparungen 25 vorgesehen sind, die hinter Querkanten
26 der ersten Bleche 11 so eingreifen, wodurch das zweite Löschblechpaket
gegenüber dem ersten Löschblechpaket positioniert ist. Dabei verlaufen die Querkanten
26 senkrecht zur Lichtbogenlaufrichtung, so dass dadurch eine Art Stufung gebildet ist,
über die der in Lichtbogenlaufrichtung gesehen vordere Bereich der ersten Lichtbogenlöschbleche
11 in einen schmaleren Bereich übergeht, so dass die beiden Streifen 24
aus isolierendem Material etwa in den Ebenen liegen, in denen sich die Streifen 14, 15
befinden. Eine weitere Fixierung des zweiten Lichtbogenlöschblechpaketes wird durch
geeignete Leisten oder Vorsprünge an der Gehäuseinnenwand des Schaltgerätes, in
das die Lichtbogenlöschblechanordnung eingesetzt werden soll, erreicht.From Fig. 1 it can be seen that on the front longitudinal edges in the arc running direction
