Abstract

The full circle rotation of the load isolating circuit breaker covers both the OFF and ON switching. Each switching phase is provided with main contacts, offset in two planes and with a switching blade also offset in two planes. The circuit breaker housing is of two-chamber design or is provided with a partition. The switching blade is mounted on bearing plates connected to earth. The stationary main contacts (1, 2) are located at the periphery of the two-part housing (3) in two offset planes. The partition (6) separates tightly the stationary contacts.

Description

Beschreibund Description

Mittelspannungslasttrenner mit Doppeltrennstelle nach dem Rotary-Prinzip. Medium-voltage switch-disconnector with double disconnection point based on the rotary principle.

Die Erfindung bezieht sich auf einen Mittelspannungslasttrenner nach dem Rotary-Prinzip dessen Schaltwalze (Schaltmesser) im gleichen Drehsinn für Aus- und Einschaltung betätigt wird. Ausgezeichnet durch die besondere Gestaltung des Schaltergehauses und den in zwei Ebenen versetzt angeordneten Kontakten Es sind Mittelspannungalastterenner bekannt, bei denen auf einer Welle gelagerte Schaltmesser oder eine Welle bildende schaltmesser iz gleichen Drehsinn für Aus- und Einschaltung betätigt werden. Die bekannten Ausführungen haben einen für das Schalt- und Isoliervermögen gemeinsamen Nachteil, daß die festehenden Hauptkontakte auf dem Umfang Kreises - in einer Kbene - angeordnet sind, d. h. meistens direkt gegenüberliegend. Die Schaltwinkel für Aus- und Einschaltung also insgesant 1800 betragen. Hierdurch sind die in Ausstellung gebildeten Trenn- und Isolierstrecken abhängig von Kreisdurchmesser begrenzt. The invention relates to a medium voltage switch according to the rotary principle whose switch drum (switch blade) rotates in the same direction for and switch-on is actuated. Distinguished by the special design of the Switch housing and the contacts arranged offset in two levels There are Medium-voltage switch isolators are known in which switching blades are mounted on a shaft or a shaft-forming switch blade iz the same direction of rotation for switching off and on be operated. The known designs have one for the switching and insulating capacity common disadvantage that the fixed main contacts on the circumference of the circle - in a plane - are arranged, d. H. mostly directly opposite. The switching angle for switching on and off, therefore, total 1,800. As a result, they are in the exhibition formed separating and insulating distances are limited depending on the diameter of the circle.

Die beim Abschalten großer Ströme erzeugten heißen, ionisierten Schaltgase können in den bekannten Löschkammersystemen nicht mehr ausreichend gekühlt, gelöscht werden. The hot, ionized switching gases generated when switching off large currents can no longer be adequately cooled or extinguished in the known extinguishing chamber systems will.

Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß das Schaltmesser - jeder Phase - in zwei Ebenen versetzt angeordnet wird. Hierdurch erst ist es möglich den Gesamtschaltwinkel der Kin- und Ausschaltung von 180° auf 360° zu vergröbern. This disadvantage is avoided according to the invention in that the Switch blade - each phase - is arranged offset in two levels. Through this first it is possible to increase the total switching angle of the kin and switch off of 180 ° 360 ° to coarsen.

Bei gleichen Schaltkammerdurchmesser werden also doppelt so große Trenn- und Isolierstrecken möglich. Hierdurch können nach der Erfindung Lastschalter mit entsprechend höherem Ausschaltvermögen bei gleichen Abmeasungen bzw. bei gleichem Ausschaltvermögen mit kleineren Abnessungen gefertigt werden .With the same interrupter chamber diameter, they are twice as large Separating and insulating distances possible. In this way, according to the invention, load switches with a correspondingly higher breaking capacity with the same dimensions or with the same Breaking capacity can be manufactured with smaller dimensions.

Die Figur 1 zeigt in Vorder- und Seitenansichten Prizzip-Darstellungen der Ausführung ein bekannten Drehlasttrenners mit eine Gesamtschaltwinkel EIN / AUS = 1800.FIG. 1 shows Prizzip representations in front and side views the design of a well-known rotary switch disconnector with a total switching angle ON / OFF = 1800.

Mit der Figur 2 wird ein Ausführungsbeispiel nach der Erfindung dargestellt mit einem Gesamtschalwinkel EIN /AUS =360° Die festsehenden Hauptkontakte 1 und 2 sind am Umfang des mindestens zweiteiligen Gehäuses 3 versetzt in zwei Ebenen angeordnet. Das ebenfalls versetzt ausgebildete Schaltmesser 4 ijt im Gehäuse 3 bzw. in Montageplatten 5 gelagert. Die im zweiteiligen Gehäuse 3 in zwei Ebenen versetzt angeordneten Hauptkontakte 1 und 2 sind durch die Schottland 6 elektrisch dicht voneinander getrennt.With the figure 2 an embodiment according to the invention is shown with a total switching angle ON / OFF = 360 ° The fixed main contacts 1 and 2 are offset in two planes on the circumference of the at least two-part housing 3 arranged. The switch blade 4 ijt in the housing 3, which is also embodied in an offset manner or stored in mounting plates 5. The two-part housing 3 in two levels staggered main contacts 1 and 2 are electrical through the Scotland 6 closely separated from each other.

Löscheinrichtungen 7 und 8 sind in bekannter Art an den Haustkontakten 1, 2 und am Schaltmesser 4 angeordnet.Extinguishing devices 7 and 8 are in a known manner on the house contacts 1, 2 and arranged on the switch blade 4.
