Abstract

The invention relates to an electric switching device with a signalling element which triggers a switching function when the closed circuit is interrupted, a relay safety assembly being switched into the closed circuit. The incoming and outgoing electrical lines from the closed circuit to the signalling element are each surrounded by a safety shielding which is connected to the earth potential of the signalling element at one end and to the protective-conductor terminal of the relay safety assembly at the other end. The secondary circuit of the transformer in the relay safety assembly is connected to the safety shielding on one side.

Description

Die Erfindung bezieht sich auf eine elektrische Schalteinrichtung gemäß dem Oberbegriff des Hauptanspruches.The invention relates to an electrical switching device according to the preamble of the main claim.

Derartige elektrische Schalteinrichtungen sind z. B. in der EP 234 523 B1 beschrieben und zwar im Zusammenhang mit einer Schließkantensicherung Derartige Schließkantensicherungssysteme sind für den Einsatz an motorisch betriebenen Türen und Toren in Gebäuden und öffentlichen Verkehrsmitteln verfahrbaren Regalen und an Schutzeinrichtungen für Maschinen vorgesehen In der eigentlichen Schaltleiste fließt ein Ruhestrom der von einer Auswerteeinheit überwacht wird. Die Kontaktgabe erfolgt durch die Unterbrechung des Ruhestromes Nach Entlastung tritt eine automatische Rücksteliung zur Schließung des Ruhestromkreises ein.Such electrical switching devices are such. B. in the EP 234 523 B1 described in connection with A closing edge safety device Such closing edge safety systems are for use on motorized Doors and gates in buildings and public transport movable shelves and on protective devices for machines provided In the actual safety edge flows Quiescent current that is monitored by an evaluation unit. The Contact is established by interrupting the quiescent current An automatic reset occurs after relief Closing the closed circuit.

Die sogenannte Auswerteeinheit - oder auch Relaissicherheitskombination genannt - ist im Stand der Technik ebenfalls in vielfältiger Form bekannt und überwacht sich ständig selbst im Ruhestromprinzip. Fehler, wie Kurzschluß-Kabelbruch-Profilunterbrechungen und Falschanschluß führen zum Abschalten der Lastschaltkreise Im Stand der Technik sind derartige Auswertegeräte mit der Fachbezeichnung "Relais-Sicherheitskombination" bezeichnet.The so-called evaluation unit - or relay safety combination called - is also in the prior art known in various forms and constantly monitors itself in the Closed-circuit principle. Errors, such as short-circuit cable break profile breaks and incorrect connection lead to shutdown of the load circuits In the prior art there are Evaluation devices with the technical name "Relay-safety combination" designated.

Bei diesen bekannten Anordnungen liegt der Nachteil vor, daß ein einseitiger Erdschluß nicht erkannt wird, da die Einrichtung weiterhin funktionsfähig bleibt.The disadvantage of these known arrangements is that a one-sided earth fault is not recognized because the device remains functional.

Der Erfindung liegt die Aufgabe zugrunde, eine Leitungsüberwachung zu schaffen die sowohl einen einfachen Erdschluß aufzeigt wie auch bei Kurzschluß entsprechend reagiert.The invention has for its object a line monitoring to create both a simple earth fault shows how to react accordingly in the event of a short circuit.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Hauptanspruches gelöst, d. h. dadurch, daß die elektrische Zuleitung des Ruhestromkreises zum Signalgeber mit einem leitenden Sicherheitsschirm ummantelt ist, der an den Schutzleiteranschluß der Relaissicherheitskombination anschließt, wobei der Sekundärstromkreis des Transformators in der Relaissicherheitskombination einseitig mit dem Sicherheitsschirm verbunden ist.This object of the invention is achieved by Features of the characterizing part of the main claim solved, d. H. characterized in that the electrical lead of the closed circuit to the signal generator with a conductive safety shield is sheathed to the protective conductor connection of the Relay safety combination connects, the secondary circuit of the transformer in the relay safety combination is connected on one side to the safety shield.

Wird eine solche Anordnung in Verbindung mit einer Schließkantensicherung eingesetzt, tritt schon bei Erdschluß der Zuleitung des Ruhestromkreises ein Steuersignal auf, das ein Abschalten der Laststromkreise bewirkt.Such an arrangement is in connection with a closing edge safety device used, already occurs when the supply line is grounded of the closed circuit on a control signal that a shutdown of the load circuits.

Zur Verdeutlichung der Erfindung wird in der Anlage ein Blockschaltbild einer im Stand der Technik bekannten Relaissicherheitskombination Typ: "BN 5983" beigefügt, wobei in dieses Blockschaltbild die erfindungsgemäße Schirmung zusätzlich eingezeichnet ist.To clarify the invention, a block diagram of a prior art safety relay combination type is in the system: "5983 BN" attached, in this block diagram, the shielding according to the invention is additionally located.

In der Zeichnung ist mit 1 die Schaltleiste und mit 6 die Befestigungsleiste für die Schaltleiste 1 dargestellt, wobei üblicherweise die Befestigungsleiste 6 aus Metall besteht. In die Schaltleiste 1 liegt oberhalb der Befestigungsleiste 6 der eigentliche Leiter 3, so wie im Stand der Technik bekannt.In the drawing, 1 is the safety edge and 6 is the mounting edge shown for the safety edge 1, usually the mounting bar 6 is made of metal. In the safety edge 1 lies above the mounting strip 6 the actual one Head 3, as known in the art.

Erfindungsgemäß ist dieser Leiter 3 mit einer Sicherheitsschirmung 5 umgeben, die gemäß der Zeichnung an den Schutzleiteranschluß PE(-) der Relaissicherheitskombination 2 angeschlossen ist, so daß dadurch schon bei Erdschluß der Zuleitung des Ruhestromkreises ein Abschalten der Laststromkreise bewirkt wird.According to the invention, this conductor 3 is provided with a safety shield 5 surrounded, according to the drawing to the protective conductor connection PE (-) of relay safety combination 2 connected is, so that this already at earth fault of the supply line of the closed circuit switching off the load circuits is effected.
