Description
Um in explosionsgefährdeten Räumen, die durch. Leistungsschalter (Ölschalter o. dgl.) entstehenden Gefahren zu vermeiden, ist vorgeschlagen worden, die Schalter selbst in einem nichtgefährdeten Raum •unterzubringen und sie vom Betriebsraum aus durch ein Steuerorgan fernzusteuern. Hierbei müssen jedoch die Steuerorgane der Leistungsschalter explosionssicher ausgebildet sein. Auch etwa benötigte besondere Anlaßgeräte, die zweckmäßig im Betriebsraum selbst untergebracht werden, müssen schlagwettersicher ausgebildet werden. Eine bekannte schlagwettersichere Ausbildung der Anlaßgeräte besteht darin, daß sie in einem völlig geschlossenen Gehäuse unter Öl arbeiten.To be used in potentially explosive areas through. Circuit breaker (oil switch or similar) To avoid resulting hazards, it has been suggested to put the switches themselves in in a non-endangered room • and pass them through from the operating room Remote control of the control unit. Here, however, the control organs of the circuit breaker must be made explosion-proof. Also needed special starting devices that suitably housed in the operating room itself, must be firedamp proof be formed. There is a known fire-weatherproof design of the starting devices in that they work in a completely closed housing under oil.
Die vorliegende Erfindung hat zur Aufgabe, die bisher üblichen Einrichtungen zu vereinfachen und zu verbilligten. Erfindungs-The present invention has for its object to the previously usual facilities simplify and cheaper. Inventive
ao gemäß werden die in dem explosionsgefährdeten Raum befindlichen Steuerorgane für die ferngesteuerten Schaltgeräte derartig mit den zugehörigen, unter Öl arbeitenden Anlaßgeräten verbunden, daß die Kontaktteile der Steuerorgane in der gleichen ÖlfüUung wie die Anlaßgeräte arbeiten.ao according to the control organs located in the potentially explosive area for the remotely controlled switchgear with the associated starting devices working under oil connected that the contact parts of the control organs in the same ÖlfüUung as the starting devices are working.
In der Zeichnung ist 'ein Ausführungsbeispiel dargestellt. Es ist hierbei gleichgültig, ob als Anlaßgerät ein Anlaßtransformator, ein Stufentransformator mit Widerständen oder ein Umschalter o. dgl. benutzt wird, ι ist der Ölbehälter des Anlaßgerätes. Die Betätigung des Anlaßgerätes erfolgt in üblicher Weise durch den Handantrieb 2. Zweckmäßig in der Nähe des Handantriebes sind die Steuerorgane 3 für die Fernsteuerung des Hauptschalters angeordnet, deren Kontakt 4 in den Ölraum des" Anlaßgerätes so weit hineinragt, daß die erforderliche Schlagwettersicherheit erreicht ist.An exemplary embodiment is shown in the drawing. It does not matter whether a starting transformer, a step transformer with resistors or a changeover switch or the like is used as the starting device, it is the oil tank of the starting device. The starter is operated in the usual way by the manual drive 2. The control elements 3 for the remote control of the main switch are conveniently located in the vicinity of the manual drive, the contact 4 of which protrudes into the oil chamber of the starter so far that the required fire protection is achieved.
Eine besonders einfache Konstruktion ergibt sich, wenn, wie in der Zeichnung dargestellt, als Betätigungsorgane Druckknöpfe verwendet werden, wobei an den beweglichen Teilen in bekannter Weise Öldichtungen angebracht werden müssen.A particularly simple construction results when, as shown in the drawing, Push buttons are used as actuators, oil seals being attached to the moving parts in a known manner Need to become.
