Description
In schlagwettergefährdeten Räumen müssen Funkenbildungen, die bei Betätigung von elektrischen Apparaten entstehen, unter allen Umständen vermieden werden. Es dürfen daher sämtliche Öffnungskontakte von Schaltern u. dgl. nicht offen montiert werden, sondern sie müssen stets von einem luftdicht schließenden Gehäuse umgeben sein. Ähnliche Schutzmaßnahmen müssen auch bei Steckvorrichtungen getroffen werden. Es kann nämlich bei Verwendung von Steckern in gefährdeten Betrieben vorkommen, daß ein Stecker gezogen wird, ehe die Leitung abgeschaltet ist. Hierbei werden Funken auftreten, die zu Schlagwetterexplosionen führen können. Es muß also dafür Sorge getragen werden, daß der Stromkreis erst spannungslos gemacht wird, ehe der Stecker gezogen werden kann.In rooms at risk of firedamp, sparks must be generated when the electrical apparatus that arise must be avoided at all costs. It may therefore all opening contacts of switches and the like are not mounted open, but they must always be surrounded by an airtight housing. Similar Protective measures must also be taken with plug devices. It can namely when using plugs In endangered companies it can happen that a plug is pulled before the line is switched off is. This will cause sparks which can lead to firedamp explosions. So it has to be taken care of be sure that the circuit is de-energized before the plug is pulled can be.

Gemäß der Erfindung wird beim Ziehen des Steckers eine zweite auf dem Haltemagnet bzw. Unterspannungsmagnet angeordnete Wicklung durch den Hüfsstecker kurzgeschlossen, so daß infolge Drosselung des Magnetflusses der Magnetanker abfällt und der Schalter abgeschaltet wird.According to the invention, when the plug is pulled, a second is on the holding magnet or undervoltage magnet arranged winding through the auxiliary connector short-circuited, so that the magnet armature drops due to the throttling of the magnetic flux and the switch is turned off.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es ist α ein schlagwettergeschützter Schalter bzw. Schütz. b ist der Magnet eines Unterspannungsauslösers, auf dem außer einer Haltewicklung c, die die normale betriebsmäßige Spannung führt, eine zweite Wicklung d aufgebracht ist. Die freien Enden der zweiten Wicklung d führen an einen Schließkontakt e, der von einem am Stecker / angebrachten Hilfsstekkerstiftg" entgegen der Wirkung einer Feder h geöffnet werden kann. Der Schalter α wird entgegen der Wirkung einer Feder/ vom Halteanker k in seiner Einschaltstellung gehalten.An exemplary embodiment of the invention is shown in the drawing. It is α a firedamp protected switch or contactor. b is the magnet of an undervoltage release on which, in addition to a holding winding c, which carries the normal operational voltage, a second winding d is applied. The free ends of the second winding d lead to a closing contact e, which can be opened by an auxiliary pluggable pin attached to the plug / against the action of a spring h . The switch α is held in its on position against the action of a spring / by the holding armature k.
Die Wirkungsweise der Anordnung ist folgende: Wird der Stecker f gezogen, so gibt der Stift g den Schließkontakt e frei, der durch die Feder h geschlossen wird. Dadurch wird die Wicklung d des Magnets b kurzgeschlossen, und zwar bevor die Steckerstifte die Buchsen der Steckdose verlassen haben. Die Amperewindungen dieser kurzgeschlossenen zweiten Wicklung d erzeugen im Magnet b einen dem Haltefluß entgegengesetzten Fluß und entmagnetisieren das Eisen so stark, daß dessen Anker k abfällt, wodurch der schlagwettergeschützte Schalter α zum Auslösen gebracht wird. Dieser Vorgang ge-The mode of operation of the arrangement is as follows: If the plug f is pulled, the pin g releases the closing contact e , which is closed by the spring h. As a result, the winding d of the magnet b is short-circuited before the plug pins have left the sockets of the socket. The ampere turns of this short-circuited second winding d generate a flux opposite to the holding flux in magnet b and demagnetize the iron so strongly that its armature k drops, causing the flameproof switch α to trip. This process

schient so schnell, daß der Stromkreis abgeschaltet wird, ehe der Stecker restlos gezogen ist. Es ist also eine Funkenbildung nicht mehr möglich, so daß die Gefahr von Schlagwetterexplosionen beseitigt ist.Shines so quickly that the circuit is switched off before the plug is completely removed is. Sparking is no longer possible, so there is a risk of firedamp explosions is eliminated.
Beim Einführen des Steckers / in die Steckdose vollzieht sich der Schaltvorgang in umgekehrter Reihenfolge. Es wird also stets der Stecker spannungslos betätigt.When the plug is inserted into the socket, the switching process is reversed Series. So the plug is always operated without voltage.
ίο Der Schließkontakt e wird so angebracht, daß er von außen nicht ohne weiteres, außer durch den Stift g, betätigt wenden kann. Dadurch wird vermieden, daß bei gezogenem Stecker f unbefugterweise der Schalter α durch Öffnen des Kontaktes e eingeschaltet wird.ίο The closing contact e is attached in such a way that it cannot be easily operated from the outside, except by the pin g . This prevents the switch α from being switched on in an unauthorized manner by opening the contact e when the plug f is pulled out.
