Description

Leitungseinführung für Elektromotoren-Schutzeinrichtungen an Klemmenkästen elektrischer Maschinen Die Erfindung bezieht sich auf eine Leitungseinführung für Elektromotor-Schutzeinrichtungen an Klemmenkästen elektrischer Maschinen. Es ist bekannt, für den Anschluß der beispielsweise zu Temperaturfühlern führenden Hilfsleitungen besondere Klemmen am Klemmenbrett anzuordnen. Diese Anordnung erfordert eine nicht unwesentliche Vergrößerung des Klemmenbrettes.Cable entry for electric motor protection devices on terminal boxes electrical machines The invention relates to a cable entry for Electric motor protective devices on terminal boxes of electrical machines. It is known for the connection of the auxiliary lines leading, for example, to temperature sensors to arrange special terminals on the terminal board. This arrangement does not require one insignificant enlargement of the terminal board.

Die Erfindung geht von der Erkenntnis aus, daß die Einführung der Hilfsleitungen am Klemmenkasten gleichzeitig zur Verklemmung der Hilfsleitungen herangezogen werden kann. Sie besteht in der Verwendung einer die Zuleitungen zu dem Klemmenkasten und die Hilfsleitungen der Schutzeinrichtung an der Motorwicklung verbindenden, an sich bekannten Steckkupplung, die in einem in die Klemmenkastenwand eingeschraubten, aus einer Fassung, einer Druckschraube und einer Dichtung bestehenden, an sich bekannten Schraubstöpsel eingesetzt ist.The invention is based on the knowledge that the introduction of the Auxiliary lines on the terminal box at the same time for jamming the auxiliary lines can be used. It consists in the use of one of the supply lines the terminal box and the auxiliary lines of the protective device on the motor winding connecting, known plug-in coupling, which in one in the terminal box wall screwed in, consisting of a socket, a pressure screw and a seal, known screw plug is used.

Die Erfindung befaßt sich also nicht mit dem bekannten Anschluß der Wicklungsenden einer elektrischen Maschine an eine Zuführungsleitung, die über einen besonderen Klemmenkasten oder, insbesondere bei kleinen Maschinen, über an dem Maschinengehäuse befestigte Durchführungen erfolgen kann.The invention is not concerned with the known connection of the Winding ends of an electrical machine to a supply line, which is via a special terminal box or, especially in the case of small machines, on the machine housing fastened bushings can be made.

Die Erfindung gibt die Möglichkeit, handelsübliche Schraubstöpsel für den Anschluß der Hilfsleitungen zu verwenden, wodurch der Anschluß der Hilfsleitungen einfacher gestaltet werden kann. Außerdem ist eine durch besondere Klemmen für die Hilfszuleitungen bedingte Vergrößerung des Klemmenbrettes und damit des Klemmenkastens vermieden. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Sie zeigt den Klemmenkasten einer elektrischen Maschine mit einer Leitungseinführung für die Hilfsleitungen im Längsschnitt.The invention gives the possibility of commercially available screw plugs to use for the connection of the auxiliary lines, whereby the connection of the auxiliary lines can be made simpler. There is also one through special terminals for the Auxiliary supply lines required enlargement of the terminal board and thus the terminal box avoided. An embodiment of the invention is shown in the drawing. It shows the terminal box of an electrical machine with a cable entry for the auxiliary lines in longitudinal section.

In die Öffnung 1 der unteren Klemmenkastenwand 2 ist eine Fassung 3 aus Metall eingeschraubt. In diese Fassung 3 ist ein Kupplungsstecker 4 aus Isoliermaterial eingelegt, durch den die Enden der Zuleitungen 5 und 6 geführt sind. Eine in die Fassung 3 eingeschraubte Druckschraube 7 hält den Kupplungsstecker 4 unter Zwischenlage einer das zu einer überwachungseinrichtung führende Kabel 8 aufnehmenden Gummidichtung 9 fest. Auf den Kupplungsstecker ist eine Kupplungsdose 10 aufgesetzt, die die Enden der Zuleitungen 11 und 12 zu einem an der Motorwicklung angeordneten Temperaturfühler aufnimmt. Die Enden der Leitungen 5 und 6 und der Leitungen 11 und 12 sind in Klemmstücken angeklemmt, die in bekannter Weise ineinandergesteckt werden können.In the opening 1 of the lower terminal box wall 2 is a socket 3 screwed in from metal. In this socket 3 is a coupling plug 4 made of insulating material inserted through which the ends of the leads 5 and 6 are passed. One in the Socket 3 screwed in pressure screw 7 holds the coupling plug 4 under an intermediate layer a rubber seal receiving the cable 8 leading to a monitoring device 9 fixed. A coupling socket 10, which has the ends, is placed on the coupling plug of the supply lines 11 and 12 to a temperature sensor arranged on the motor winding records. The ends of the lines 5 and 6 and the lines 11 and 12 are in clamping pieces clamped, which can be plugged into one another in a known manner.
