Abstract
Niederspannungs-Durchführung für Schaltanlagen, insbesondere Mittelspannungsschaltanlagen, bei welcher innerhalb mehrerer Compartments Steuerkabel im Niederspannungsbereich durchgeführt werden, dadurch gekennzeichnet, dass vorgefertige Öffnungen innerhalb der Wandungen zwischen den Compartments eingebracht sind, und dass die Durchführung in die besagte Öffnung einbringbar ist, und als schlauchförmige Durchführung ausgestaltet ist, durch welche die besagten Steuerkabel hindurchführbar sind,Low-voltage feedthrough for switchgear, in particular medium-voltage switchgear, in which within several Compartments control cables are performed in the low voltage range, characterized in that prefabricated openings are introduced within the walls between the Compartments, and that the implementation is introduced into said opening, and as a tubular passage is designed, through which the said control cables are passed,
Description
Die Erfindung betrifft eine Niederspannungs-Durchführung für Schaltanlagen, insbesondere Mittelspannungsschaltanlagen, gemäß Oberbegriff des Anspruches 1. The invention relates to a low-voltage feedthrough for switchgear, in particular medium-voltage switchgear, according to the preamble of claim 1.
Bei bekannten Einrichtungen dieser Art ist es nicht möglich, Durchführungen überall auf den Wänden von Schaltanlagen zu platzieren, ohne die spezifische Berücksichtigung von Kabeln, Röhren etc. Dabei ist außerdem die Schutzvorschrift IP 4X zu erfüllen. Bekannnte Durchführungen müssen zumeist daran angepasst werden, was die Montage erschwert. In known devices of this type, it is not possible to place bushings anywhere on the walls of switchgear, without the specific consideration of cables, tubes, etc. In addition, the protection requirement IP 4X must be met. Known bushings usually have to be adapted, which makes assembly difficult.
Der Erfindung liegt daher die Aufgabe zugrunde, Durchführungen nach der Schutzvorschrift IP 4X zu schaffen, die einfacher montierbar sind. The invention is therefore based on the object to provide bushings according to the protection IP 4X, which are easier to install.
Die gestelle Aufgabe wird bei einer Niederspannungsdurchführung der gattungsgemäßen Art, erfindungsgemäß durch die kennzeichnenden Merkmale des Schutzanspruches 1 gelöst. The object is achieved in a low-voltage implementation of the generic type, according to the invention by the characterizing features of the protection claim 1.
Weitere vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen angegeben. Further advantageous embodiments are specified in the dependent claims.
Die Erfindung gibt an, dass vorgefertige Öffnungen innerhalb der Wandungen zwischen den Compartments eingebracht sind, und dass die Durchführung in die besagte Öffnung einbringbar ist, und als schlauchförmige Durchführung ausgestaltet ist, durch welche die besagten Steuerkabel hindurchführbar sind. The invention indicates that prefabricated openings are made within the walls between the compartments, and that the passage can be introduced into said opening, and is designed as a hose-like passage through which said control cables can be passed.
In weiterer vorteilhafter Ausgestaltung ist angegeben, dass eines den lichten Durchmesser einstellbar reduzierendes Einschnürelement vorgesehen ist, mitsamt welchem die Steuerkabel oder der Steuerkabelstrang derart verschließbar ist, dass zumindest die Schutzvorschrift IP 4X erfüllbar ist. In a further advantageous embodiment, it is stated that a constricting element which reduces the clear diameter is provided, together with which the control cable or the control cable strand can be closed in such a way that at least the protection regulation IP 4X can be satisfied.
Weiterhin ist vorteilhaft ausgestaltet, dass die Durchführung aus einem isolierenden, flexiblen Kunststoff oder Gummi besteht. Furthermore, it is advantageously designed that the implementation consists of an insulating, flexible plastic or rubber.
In letzter vorteilhafter Ausgestaltung ist angegeben, dass die Durchführung zumindest an einer Seite einen einstückig angeformten Flansch aufweist, welcher mit umlaufend angeordneten Öffnungen versehen, ist, durch welche hindurch die Durchführung mittels Schrauben an der Wandung des Compartments der Schaltanlage befestigbar ist. In the last advantageous embodiment it is stated that the bushing has an integrally formed flange on at least one side, which is provided with circumferentially arranged openings through which the bushing can be fastened by means of screws to the wall of the compartment of the switchgear.
Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt und nachfolgend näher beschrieben. An embodiment of the invention is illustrated in the drawing and described in more detail below.
Es zeigt: It shows:
Wenn dann dort hindurch Kabel angelegt werden, kann der weiche Abschnitt der Durchführung bspw. mit einem Rasterband eingeschnürt werden. If then cables are applied therethrough, the soft portion of the implementation can be, for example. Constricted with a grid tape.
