Description

Die Erfindung bezieht sich auf eine Einrichtung zum Fernabschalten von Verbrauchern in Netzen, die durch Fehlerstromschutzschalter geschützt sind, insbesondere in Notsituationen.The invention relates to a device for remote disconnection of consumers in networks through Residual current circuit breakers are protected, especially in emergency situations.

Es sind sogenannte Einrichtungen zur Not-Aus-Schaltung auf dem Markt, Lei denen von einem handbetätig- Jo baren Schalter bzw. Taster über Steuer.'^itungen auf ein Relais eingewirkt wird, das einen Hauptschalter im Netz zum Auslösen bringt. Solche Einrieiitunf:n müssen am zu schützenden Verbraucherplatz, beispielsweise am Laborplatz, von Anfang an installiert sein, oder die J5 Einrichtung ist nachträglich unter erhöhtem Aufwand zu installieren.There are so-called devices for emergency stop on the market, Lei those of a hand-operated Jo switch or button via control units on Relay is acted, which brings a main switch in the network to trigger. Such arrangements must be made on consumer space to be protected, for example at the laboratory space, must be installed from the start, or the J5 Equipment is to be installed later with increased effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Fernabschaiten von durch Fehierstromschalter geschützten Verbrauchern in Notsituatio- ·»<> nen zu entwickeln, die ohne zusätzlich zu verlegende Steuerleitungen auskommt und in üblichen Steckdosen, sogenannten Schuko-Steckdosen, wie ein Verbraucher eingesteckt werden kann.The invention is based on the object of providing a device for remote disconnection of faulty current switches Protected consumers in emergency situations to develop · »<> without additional laying Control lines get by and in common sockets, so-called Schuko sockets, like a consumer can be plugged in.

Die geschilderte Aufgabe wird mit einer Einrichtung 4 gelöst, die die Merkmale nach dem kennzeichnenden Teil des Hauptanspruchs aufweist. Diese Einrichtung erzeugt an einer Stelle zwischen Fehlerstromschutzschalter und Verbraucher eine Asymmetrie, die den Fehlerstromschutzschalter zum Ansprechen bringt. '><> Dadurch erübrigt sich ein eigener Hauptschalter zum Unterbrechen des Netzes. Diese Einrichtung kommt also mit extrem wenigen zusätzlichen Bauteilen aus. Sie kann an einer im Blickfeld liegenden Stelle in eine Steckdose eingesetzt werden. Sie läßt sich jederzeit wieder abziehen und an anderer Stelle verwenden. Die Begrenzungswiderstände sind lediglich so zu wählen, daß im Streubereich der Netzspannung mindestens d<ir Nennauslösestrom des vorgeschalteten Fehlerstromschutzschalters fließen kann.The described task is carried out with a device 4 solved, which has the features according to the characterizing part of the main claim. This facility creates an asymmetry at one point between the residual current circuit breaker and the consumer, which causes the Brings residual current circuit breaker to respond. '> <> This eliminates the need for a separate main switch for Interrupt the network. This device therefore needs extremely few additional components. she can be inserted into a socket at a point in the field of vision. She leaves at any time peel it off again and use it elsewhere. The limiting resistors are only to be selected in such a way that that in the scatter range of the mains voltage at least d <ir Rated tripping current of the upstream residual current circuit breaker can flow.

Es ist günstig, durch eine Anzeigelampe die Bereitschaft der Einrichtung anzuzeigen. Wenn zwischen den Verbindungsleitungen zu den Steckanschlüssen ein Lampentransformator mit der Anzeigelampe eingeschaltet ist, erhält man auch eine Kontrolle, ob das Betätigen der Einrichtung zum Abschalten des Verbrauchers geführt hat, indem die Lampe erlischt. Zweckmäßigerweise wird die Anzeigelampe im Betätigungsorgan angeordnet.It is advantageous to indicate that the facility is ready by means of an indicator lamp. If between the connection lines to the plug connections a lamp transformer with the indicator lamp is switched on, a check is also made as to whether the device for switching off the consumer is being operated by turning the lamp off. The indicator lamp is expediently in the actuator arranged.

Die Erfindung soll anhand eines in der Zeichnung schematisch wiedergegebenen Ausführungsbeispieis näher erläutert werden:The invention is intended to be based on an exemplary embodiment shown schematically in the drawing are explained in more detail:

In Fig. 1 ist der grundsätzliche Aufbau veranschaulicht In Fig. 1 the basic structure is illustrated

In Fi g. 2 ist ein Ausführungsbeispiel für den äußeren Aufbau der Einrichtung wiedergegeben.In Fi g. 2 is an embodiment for the exterior Structure of the facility reproduced.

Die Einrichtung zum Fernabschalten von Verbrauchern in Notsituationen weist ein Gehäuse 1 mit zwei Steckanschlüssen 2 und Schutzleiterkontakten 3 auf. Die Steckanschlüsse 2 sind über Begrenzungswiderstände 4 und jeweils einen mittels eines Betätigungsorgans 5 einschaltbaren Kontakt 6 mit dem Schutzleiterkontakt 3 verbunden. Die Begrenzungswiderstände 4 sind so bemessen, daß im Streubereich der Netzspannung mindestens der Nennauslösestrom des vorgeschalteten Fehlerstromschutzschalters fließen kann.The device for remote switching off of consumers in emergency situations has a housing 1 with two Plug-in connections 2 and protective conductor contacts 3. The plug connections 2 are via limiting resistors 4 and in each case one contact 6, which can be switched on by means of an actuating element 5, with the protective conductor contact 3 tied together. The limiting resistors 4 are dimensioned so that in the scatter range of the mains voltage at least the rated tripping current of the upstream residual current circuit breaker can flow.

Zwischen den Verbindungsleitungen zu den Steckanschlüssen 2 ist ein Lampentransformator 7 mit einer Anzeigelampe 8 eingeschaltet. In den Vcrbindungsleitungen zu den Siei-kanschiüssen 2 isi jeweils ein einschaltbarer Kontakt 6 angeordnet, um sicherzustellen, daß in jeder Stecklage die Einrichtung zum Abschalten in einer Notsituation führt.Between the connecting lines to the plug connections 2 is a lamp transformer 7 with a Indicator lamp 8 switched on. In the connecting lines to the Siei-kanschiusses 2 isi each one Switchable contact 6 arranged to ensure that the device for Shutting down in an emergency situation.

Aus Fig. 2 ist ein Ausführungsbeispiel für den äußeren Aufbau des Gehäuses 1 der Einrichtung in perspektivischer Darstellung zu ersehen. Die Steckanschlüsse 2 sind in einem Stecksockel 9 angeordnet, der versetzt zur Anordnungsebene der Steckanschlüsse 2 Schutzleiterkontakte 3 aufweist. Dieser Aufbau entspricht der üblichen Ausbildung von Steckern für Schuko-Steckdosen. Im Betätigungsorgan 5 ist die Anzeigelampe 8 angeordnet.From Fig. 2 is an embodiment for the external structure of the housing 1 of the device in to be seen in perspective representation. The plug connections 2 are arranged in a socket 9, the has offset to the arrangement plane of the plug connections 2 protective conductor contacts 3. This structure corresponds to the usual design of plugs for Schuko sockets. In the actuator 5 is the Indicator lamp 8 arranged.
