Isolierstoffgehäuse für VakuumschalterInsulated housing for vacuum switches

Die Neuerung bezieht sich auf ein Isolierstoffgehäuse für Vakuumschalter, bei dem kein gesonderter Kondensationsschirm zur Aufnahme verdampften Kontaktmaterials erforderlich ist.The innovation relates to an insulating housing for vacuum switches, which does not require a separate condensation screen to absorb the vaporized contact material.

Beim Abschalten eines Stromes im Vakuumschalter verdampft Kontaktmaterial, das an den die Kontakte umgebenden V/änden des Gehäuses wieder kondensiert und auf diesem einen leitenden Belag bildet. Zur Potentialtrennung im Inneren des Schalters ist es erforderlich, durch einen sogenannten Kondensationsschirm den leitenden Belag vom Gehäuse fernzuhalten, um die für die angelegte Spannung erforderliche Kriechstrecke zu erhalten.When a current is switched off in the vacuum switch, contact material evaporates, which condenses again on the walls of the housing surrounding the contacts and forms a conductive coating on it. To isolate the potential inside the switch, it is necessary to use a condensation screen to make the conductive one Keep the coating away from the housing in order to obtain the necessary creepage distance for the applied voltage.

Der Neuerung liegt die Aufgabe zugrunde, ein Gehäuse für Vakuumschalter zu entwickeln, ohne daß der obengenannte Kondensationsschirm erforderlich ist. The innovation is based on the task of a housing for vacuum switches to develop without the need for the aforementioned condensation screen.

Gemäß der Neuerung ist das Isolierstoffgehäuse als Hohlzylinder ausgebildet, in dessen Stirnflächen jeweils mindestens eine ringförmige Vertiefung vorgesehen ist.According to the innovation, the insulating housing is a hollow cylinder formed, in each of the end faces at least one annular recess is provided.

Die Neuerung bietet den technischen Vorteil eines besonders einfach aufgebauten Gehäuses für einen Vakuumschalter bei gleichzeitiger Erhaltung der für die angelegte Spannung erforderlichen Isolierstrecke.The innovation offers the technical advantage of being particularly simple built-up housing for a vacuum switch while maintaining the required voltage for the applied voltage Insulating section.

Ed hat sich als besonders vorteilhaft erwiesen, die Vertiefungen so zu bemessen, daß sie jweils etwa 15 % der Gesamtlänge des Gehäuses betragen und daß die seitlichen Begrenzungen der Vertiefungen von unterschiedlicher Höhe sind.Ed has been found to be particularly beneficial to the indentations to be dimensioned so that they are each about 15% of the total length of the housing and that the lateral boundaries of the wells are of different heights.

An einem in der Zeichnung dargestellten Ausführungsbeispiel wird die Neuerung näher erläutert.The innovation is explained in more detail using an exemplary embodiment shown in the drawing.

In der Figur ist ein Isolierstoffgehäuse für Vakuumschalter gemäß der Neuerung im Längsschnitt dargestellt.In the figure, an insulating housing for vacuum switches according to the innovation is shown in longitudinal section.

Das Gehäuse besteht aus einem Hohlzylinder 2_, z.B. aus Glas oder Keramik. In die gegenüberliegenden Stirnflächen 2 und 3 des Kohlzylinders _1_ sind die ringförmigen Vertiefungen 4 und 5 eingedreht, gedrückt, geblasen oder gepreßt. Die Begrenzungen 6 und 7 der Vertiefungen 4 und 5 sind von unterschiedlicher Höhe bzw. Länge. Im Beispielsfalle sind die Begrenzungen 7 kürzer als die Begrenzungen 6. Die Vertiefungen 4 und 5 bewirken, daß sich beim Schalten eines Stromes im Inneren der Vertiefungen entlang der punktierten Linie 8 (Fadenlänge jeweils ca. 30 mm) kein von den Kontakten verdampfendes Material niederschlagen kann, weil dieser Bereich im Schatten der Dampfemission liegt. Dadurch wird die erforderliche Isolierstrecke im Vakuum am Isoliergehäuse erhalten. Das verdampfende Material kondensiert lediglich an der gestrichelt gezeichneten Linie 9 (Kondensationszone).The housing consists of a hollow cylinder 2_, for example made of glass or ceramic. The annular depressions 4 and 5 are screwed, pressed, blown or pressed into the opposite end faces 2 and 3 of the cabbage cylinder _1_. The boundaries 6 and 7 of the depressions 4 and 5 are of different heights and lengths. In the example, the boundaries 7 are shorter than the boundaries 6. The depressions 4 and 5 ensure that when a current is switched inside the depressions along the dotted line 8 (thread length approx. 30 mm each), no material evaporating from the contacts can be deposited because this area is in the shadow of steam emissions. As a result, the required insulating distance is obtained in the vacuum on the insulating housing. The evaporating material condenses only on the dashed line 9 (condensation zone).
