Description

Hochspannungsklemmenkasten für elektrische Maschinen Die Erfindung bezieht sich auf einen Hochspannungsklemmenkasten für elektrische Maschinen, dessen Deckel nahtförmige Stellen mit geringer mechanischer Festigkeit besitzt, nach Patent 842 363. Nach dem Hauptpatent erstrecken sich diese nahtförmigen Stellen über einen Teil der Länge und/oder Breite der Stirnflächen des Klemmenkastendeckels. Bei dieser Ausführung kann unter Umständen die waagerecht heraustretende Explosionsflamme eine vor dem Klemmenkasten stehende Person gefährden.High-voltage terminal box for electrical machines The invention refers to a high voltage terminal box for electrical machines, its Lid has seam-shaped points with low mechanical strength, according to patent 842 363. According to the main patent, these seam-like areas extend over a Part of the length and / or width of the end faces of the terminal box cover. At this Execution may cause a horizontally emerging explosion flame endanger anyone standing in front of the terminal box.

Durch die Erfindung werden diese Mängel beseitigt. Erfindungsgemäß erstrecken sich die nahtförmigen Stellen mit geringer mechanischer Festigkeit über einen Teil der Länge und/oder Breite einer oder mehrerer Seitenflächen, vorzugsweise der nach oben gerichteten Seitenfläche des Klemmenkastendeckels. Bei einer Explosion kann die Flamme nur seitlich oder nach oben austreten.The invention overcomes these deficiencies. According to the invention the seam-like areas with low mechanical strength extend over part of the length and / or width of one or more side surfaces, preferably the upward facing side surface of the terminal box cover. In an explosion the flame can only emerge laterally or upwards.

Es sind bereits Schutzeinrichtungen an Klemmenkästen bekanntgeworden, die bei Auftreten einer Explosion in Tätigkeit treten. So hat man beispielsweise an den Seitenflächen eines Apparates Verschlüsse angeordnet, die beim Auftreten eines Überdruckes im Inneren herausgedrückt weirden. Bei .einem bekannten Klemmenkasten besteht ein Teil der Gehäusewand aus einem Material mit geringer mechanischer Festigkeit, beispielsweise Papier oder Asbest. Dieser Teil wird bei einer Explosion zerstört. Gegenüber diesen bekannten Schützeinrichtungen ermöglicht die erfindungsgemäße Anordnung von nahtförmigen Stellen eine einfachere Ausführung des Klemmenkastens.Protective devices on terminal boxes have already become known, that come into action when an explosion occurs. So you have, for example arranged on the side surfaces of an apparatus closures that occur when an overpressure inside. With .a known terminal box consists of a part the housing wall made of a material with low mechanical strength, for example paper or asbestos. This part is at destroyed in an explosion. Compared to these known contactor devices the inventive arrangement of seam-shaped places a simpler execution of the terminal box.
