Gekapselter SchalterEncapsulated switch
Die Neuerung betrifft einen druckfest gekapselten Schalter gemäß Oberbegriff des Anspruches 1.The innovation relates to a flameproof switch according to the preamble of claim 1.
Kin solcher geht aus dem DE-GM 1 946 377 als bekannt hervor. Hierbei handelt es sich um einen Niederspannungsschalter,der eigenmagnetisch betätigbar ist. Zwischen Schalter- und Druckkapselungsgehäuse ist Sand eingefüllt.Kin such emerges from DE-GM 1 946 377 as known. This is a low-voltage switch that can be operated magnetically. Between switch housing and pressurized enclosure is filled with sand.
Bei einem oder mehreren in Reihe angeordneten Vakuumschaltern gemäß US-PS 2 915 611 ist es bekannt, ate Vakuumröhre in einem isolierenden Schutzgehäuse anzuordnen und den Raum zwischen Röhren- und Schutzgehäuse mit einem isolierenden elastischen zellenartigen Schaumstoff auszufüllen. Damit soll ein mechanischer Schutz der Röhre beim Transportieren sichergestellt werden; an eine druckfeste Kapselung ist dabei nicht gedacht.In one or more series-arranged vacuum switches according to US Pat. No. 2,915,611, it is known to use ate vacuum tube in one to arrange insulating protective housing and the space between the tube and protective housing with an insulating elastic cell-like foam to be filled. This is to ensure mechanical protection of the tube during transport will; Pressure-proof encapsulation is not intended.
Die Aufgabe der Neuerung ist es, einen mehrpoligen Hochspannungsschalter, insbesondere für den Untertage-Bergbau, anzugeben, der ohne ein brennbares oder gasendes Löschmedium auskommt, wartungsarm ist und sich in geeigneter Weise druckfest kapseln läßt.The task of the innovation is to provide a multi-pole high-voltage switch, in particular for underground mining, which works without a flammable or gaseous extinguishing medium, is low-maintenance and can be encapsulated in a suitable manner pressure-tight.
Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des Anspruches 1 dargestellt.The solution to this problem is in the characterizing part of the claim 1 shown.
Der neue Schalter tritt an die Stelle der Flüssigkeits-Leistungsschalter, die in Untertagefeldern in Räumen erhöhter Sicherheit bisher eingebaut worden waren. Vom Löschmedium des Leistungsschalters geht für den Untertagebetrieb keinerlei Gefahr aus.The new switch takes the place of the liquid circuit breaker, which had previously been installed in underground fields in areas of increased security. From the extinguishing medium of the circuit breaker there is no danger for underground operations.
Bei Verwendung von Vakuumschaltern muß jedoch sichergestellt sein, daß im Falle des Leckwerdens ihres Schaltergehäuses oder ihres Balges heiße Lichtbogenprodukte bei einem Schaltversagen nicht in den Raum erhöhter Sicherheit gelangen.When using vacuum switches, however, it must be ensured that in the event of leakage of their switch housing or In the event of a switching failure, hot arcing products cannot get into the increased safety area of their bellows.
Der Durchtritt der Antriebsstange des Schalters durch die Druckkapselung ist mit einem langen und eng bemessenen Spalt vorgenommen, damit der Austritt glühender Partikel auch hier ausgeschlossen ist.The passage of the actuator stem of the switch through the pressure encapsulation is made with a long and narrow gap so that the escape of glowing particles is also ruled out here is.
Mit der neuen Ausbildung des Schalters ist sichergestellt, daß die Vorteile eines Vakuum-Leistungsschalters auch im sogenannten MittelSpannungsbereich für explosionsgefährdete Betriebsstätten, insbesondere im Untertage-Bergbau, genutzt werden können.With the new design of the switch it is ensured that the advantages of a vacuum circuit breaker also in the so-called Medium voltage range for hazardous locations, especially in underground mining.
Als besonders vorteilhaft wird angesehen, den Raum zwischen dem Vakuumschalter- und dem Druckkapselungsgehäuse mit einem lichtbogenlöschenden Isolierschaum auszufüllen.It is considered particularly advantageous to cover the space between the vacuum switch housing and the pressure encapsulation housing with an arc-extinguishing device Fill in insulating foam.
An Hand der anliegenden Zeichnung soll die Neuerung näher erläutert werden.The innovation is to be explained in more detail using the attached drawing will.
Das Druckkapselungsgehäuse besteht aus einem, etwa mittels Glasfasern armierten Isolierstoffzylinder 1, in dem beidseitig Metallflansche 2, 2a eingesetzt und mit dem Isolierstoffzylinder 1 an umfänglich verlaufenden Flanschen 3 durch eine Verklebung verbunden sind. Die Metallflansche sind in den Isolierstoff zylinder hinein verschoben, so daß die übergreifenden Endstücke des Isolierstoffzylinders 1 zu Befestigungszwecken herangezogen werden können.The pressure encapsulation housing consists of an insulating material cylinder 1, reinforced for example by means of glass fibers, in which on both sides Metal flanges 2, 2a inserted and with the insulating cylinder 1 are connected to circumferentially extending flanges 3 by gluing. The metal flanges are in the insulating material cylinder moved in, so that the overlapping end pieces of the insulating material cylinder 1 are used for fastening purposes can be.
Beide Metallflansche werden als Stromzu- und -ableiter für den Vakuumschalter 5 verwendet und besitzen durch Öffnungen im Isolierstoff zylinder nach außen tretende Anschlüßarme 6, 6a.Both metal flanges are used as current feeders and arresters for the vacuum switch 5 and have openings in the insulating material cylinder outwardly stepping connecting arms 6, 6a.
Der innerhalb des Isolierstoffzylinders mit einigem Abstand angeordnete Vakuum-Leistungsschalter 5 besitzt ein Schaltergehäuse 7. In dieses ragt vakuumdicht der feststehende Leiterstab 8 mit dem Kontaktelement 9 sowie der bewegliche Leiter-The one arranged within the insulating material cylinder with some distance Vacuum circuit breaker 5 has a switch housing 7. The stationary conductor bar protrudes into this in a vacuum-tight manner 8 with the contact element 9 and the movable conductor

stab 10 mit dem entsprechenden Kontaktelement 11. Für den vakuumdichten Durchtritt des Leiterstabes 10 sorgt der Balg 12.rod 10 with the corresponding contact element 11. For the vacuum-tight The bellows 12 ensures passage of the conductor bar 10.
Der Metallflansch 2 ist über den Schaft 13 kontaktgebend mit dem Leiterstab 8 verbunden.The metal flange 2 is connected to the conductor bar 8 in a contact-making manner via the shaft 13.
Die Stromübergabe vom beweglichen Leiterstab 10 zum Metallflansch 2a erfolgt über ein am Leiterstab befestigtes Reibkontaktelement 14, das in einem zum Vakuumschalter hin gerichteten Kontaktzylinder 15 des Metallflansches 2a kontaktgebend verschiebbar angeordnet ist. Hierbei ist die Kontaktübergabe in den druckfest gekapselten Raum verlegt. Gleichwohl ist es möglich, den Anschluß außerhalb dieses Raumes - etwa unter Zuhilfenahme eines Kontaktbandes - vorzunehmen.The current transfer from the movable conductor bar 10 to the metal flange 2a takes place via a friction contact element attached to the conductor bar 14, which makes contact in a contact cylinder 15 of the metal flange 2a directed towards the vacuum switch is arranged displaceably. Here, the transfer of contacts is relocated to the pressure-proof encapsulated room. Nevertheless it is possible to make the connection outside of this space - for example with the help of a contact tape.
Der Antrieb des Vakuumschalters geschieht über eine bewegliche, isolierte, mit dem Leiterstab 10 gekoppelte Antriebsstange 16. Diese ist durch den Metallflansch 2a aus den druckdichten Raum herausgeführt. Am Durchtritt wird sie von einer eng anliegenden, langen, im Metallflansch eingesetzten Buchse 17 umgriffen. Der Spalt an der Durchtrittsstelle ist so bemessen, daß glühende Partikel in keinem Falle nach außen dringen können.The vacuum switch is driven by a movable, insulated drive rod 16 coupled to the conductor rod 10. This is through the metal flange 2a out of the pressure-tight space led out. At the passage it is encompassed by a tightly fitting, long bush 17 inserted in the metal flange. Of the The gap at the point of passage is dimensioned in such a way that glowing particles cannot in any case penetrate to the outside.
Zwischen dem Vakuum-Schaltergehäuse und der druckfesten Kapselung, dem Isolierstoffzylinder 1, ist ein Isolierschaum 18 eingebracht, der lichtbogenlöschend eingestellt sein kann. Möglich ist ein geschlossenporiger Schaum, der ein elektronegatives Gas, wie SF,, enthält.Between the vacuum switch housing and the flameproof enclosure, the insulating material cylinder 1 is an insulating foam 18 introduced, which can be set to be arc-extinguishing. A closed-cell foam, which is an electronegative one, is possible Contains gas, such as SF ,,.
