Es ist ein Vakuumschalter bekannt, dessen beweglicher Schaltkontakt vom beweglichen Schaltkontakt eines mit dem Vakuumschalter in Reihe liegenden Spannungstrennschalters mit freier Lufttrennstrecke unmittelbar betätigt wird. Die Erfindung bezieht sich auf einen derartigen Vakuumschalter.A vacuum switch is known whose moving switch contact is separated from the moving switch contact a voltage disconnector in series with the vacuum switch with a free air separation distance is operated immediately. The invention relates to such a vacuum switch.

Während der bekannte Vakuumschalter so aufgebaut ist, daß sein beweglicher Schaltstift auch den Gegenkontakt des beweglichen Trennorgans, in diesem Fall ein schwenkbares Trennmesser, trägt, ist bei dem erfindungsgemäßen Schalter der Spannungstrennschalter als Schubtrennschalter mit einem am Gehäuse des Vakuumschalters fest gelagerten Ringkontakt ausgebildet und erfolgt die Kraftübertragung zwischen den beiden beweglichen Kontakten durch den Ringkontakt hindurch. Es ergibt sich so ein sehr einfacher Aufbau des Schalters, der vor allem den Vorteil hat, daß die Trennstrecke am Schubtrenner von vornherein festliegt, so daß man Maßnahmen treffen kann, um die Trennstrecke, z.B. durch Anbringen von abgerundeten Flächen an den Kontakten, möglichst kurzzuhalten. Außerdem wird bei der Einschaltung auch zunächst stets der Schubtrenner sicher eingeschaltet, bevor der Vakuumschalter geschlossen wird.While the known vacuum switch is constructed so that its movable switch pin also the Mating contact of the movable separating element, in this case a pivoting separating knife, carries is in the switch according to the invention, the voltage disconnector as a push disconnector with an am Housing of the vacuum switch is formed with a fixed ring contact and the power is transmitted between the two movable contacts through the ring contact. It turns out so much simple construction of the switch, which has the main advantage that the isolating distance on the push separator is fixed from the start, so that measures can be taken to reduce the isolating distance, e.g. by attaching of rounded surfaces on the contacts, to be kept as short as possible. In addition, when switching on Also, the push separator is always switched on safely before the vacuum switch closes will.

Bei dem bekannten Vakuumschalter mit angebautem Messertrennschalter sind diese Vorzüge nicht vorhanden, weil weder das Trennmesserende noch der Gegenkontakt des Trennschalters das Anbringen von abgerundeten Flächen zur Verkürzung der Trennstrecke zulassen und weil ferner der beweglich gelagerte Gegenkontakt schon bei normal eingestelltem Kontaktdruck ein Mitnehmen des beweglichen Schaltkontaktes des Vakuumschalters zulassen würde, bevor das Trennmesser voll eingeschaltet ist. Letzteres würde bei einer Einschaltung auf einen Kurzschluß zur Beschädigung der Kontaktstellen am Trennschalter führen.These advantages do not exist in the known vacuum switch with built-on knife disconnector present, because neither the end of the cutting knife nor the mating contact of the disconnector does not need to be attached of rounded surfaces to shorten the separation distance and because furthermore the movable mounted mating contact means that the movable one is taken along even with the contact pressure set normally Switching contact of the vacuum switch would allow before the cutting knife is fully switched on. The latter a short circuit would damage the contact points on the disconnector when switched on to lead.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in zwei Ansichten dargestellt.An embodiment of the invention is shown in the drawing in two views.

In F i g. 1 ist mit 1 die Schaltkammer des Vakuumschalters bezeichnet, die in der Achsrichtung des Schubtrenners 2 angeordnet ist. Der Schubtrenner wird von zwei Stützern 3 getragen, die auf einem Tragrahmen 4, der zugleich den Antrieb des Schubtrenners enthält, befestigt sind. Der Antrieb 5 ist halbpneumatisch ausgebildet.

The shear separator is supported by two supports 3 , which are attached to a support frame 4, which also contains the drive of the shear separator. The drive 5 is semi-pneumatic. To switch on, compressed air supplied via opening 6 and to the vacuum switch are used

Ausschalten eine Feder 7. Die Antriebsbewegung des Kolbens 8 wird über eine Schaltschwinge 9 auf den beweglichen Schaltstift 10 des Schubtrenners übertragen. Zur Abbremsung der Ein- und Ausschaltbewegung dient eine Ölbremse 11. In der Einschaltstellung wird die Schaltschwinge 9 durch eine Sperrklinke 12, die an die Kolbenstange 13 angreift, verriegelt. Zur Ausschaltung muß diese Sperrklinke über einen Antrieb 14 gelöst werden. In der Ausschaltstellung besteht eine sichtbare Spannungstrennstrecke zwischen den beiden Schaltkontakten des Schubtrenners, wie aus F i g. 1 ersichtlich ist.Switching off a spring 7. The drive movement of the piston 8 is transmitted via a switching rocker 9 to the movable switching pin 10 of the push disconnector. An oil brake 11 is used to brake the switch-on and switch-off movement. In the switch-on position, the rocker arm 9 is locked by a pawl 12 which engages the piston rod 13. To switch off this pawl must be released via a drive 14 . In the switch-off position, there is a visible voltage separating section between the two switching contacts of the sliding disconnector, as shown in FIG. 1 can be seen.

Damit beim Einschalten der Schaltstift 10 des Schubtrenners nicht auf den metallischen Schaltstift des Vakuumschalters trifft und diesen dadurch etwa beschädigt, ist es zweckmäßig, am Antriebsende des beweglichen Schaltstiftes des Vakuumschalters einen Kunststoff körper 15, z.B. aus Teflon, zu befestigen. Dabei müssen dann zur Stromübertragung zwischen den beweglichen Schaltkontakten in dem Metallgehäuse 16 angeordnete Gleitkontakte 17 und 18 vorgesehen sein, wie F i g. 2 zeigt.So that when switching on the switch pin 10 of the push disconnector does not hit the metallic switch pin of the vacuum switch and thereby damage it, it is useful to attach a plastic body 15, for example made of Teflon, to the drive end of the movable switch pin of the vacuum switch. In this case, sliding contacts 17 and 18 arranged in the metal housing 16 must then be provided for power transmission between the movable switching contacts, as shown in FIG. 2 shows.

Der Kunststoffkörper 15 steht unter dem Druck einer Feder 19, die bei der Ausschaltbewegung des Schubtrenners noch vor dem Herausgleiten des Schaltstiftes 10 aus dem Gleitkontakt 17 den Vakuumschalter öffnet und damit die Leistungsunterbrechung vornimmt.The plastic body 15 is under the pressure of a spring 19, which opens the vacuum switch when the sliding disconnector is switched off before the switching pin 10 slides out of the sliding contact 17 and thus interrupts the power.

Der Schaltstift 20 des Vakuumschalters steht unter dem Druck einer Feder 21, die ihm den nötigen Kontaktdruck in der Einschaltstellung vermittelt. Der Schalthub des Schaltstiftes 20 wird durch eine Buchse 22, die auf einen Anschlag 23 trifft, begrenzt.The switching pin 20 of the vacuum switch is under the pressure of a spring 21, which gives it the necessary contact pressure in the switched-on position. The switching stroke of the switching pin 20 is limited by a socket 22 which strikes a stop 23.

Wie die Zeichnung erkennen läßt, bedeutet die Anordnung einer Spannungstrennstrecke im Weg der Schaltstiftbetätigung des Vakuumschalters in der erfindungsgemäßen Weise gegenüber den bekannten Lasttrennern mit einer Vakuumschaltkammer eine wesentliche technische Verbesserung.As the drawing reveals, the arrangement of a voltage isolating section in the path of the Switching pin actuation of the vacuum switch in the manner according to the invention compared to the known Switch disconnectors with a vacuum interrupter chamber represent a significant technical improvement.
