Elektromagnetischer Stromauslöser für einen elektrischen Schutzschalter

Electromagnetic current release for an electrical circuit breaker
5

Die Erfindung bezieht sich auf einen elektromagnetischen Stromauslöser für einen elektrischen Schutzschalter mit einer Magnetspule, einem beweglichen Anker und einem ortsfesten Magnetkern, der durch eine Stromanschlußklemme der Magnetspule gehalten ist.The invention relates to an electromagnetic current release for an electrical circuit breaker with a magnetic coil, a movable armature and a stationary magnetic core, which is held by a current connection terminal of the magnetic coil.

Gattungsgemäße elektromagnetische Stromauslöser gemäß FIG 2 werden zur Erkennung von Überströmen, insbesondere von Kurzschlußströmen, bei konventionellen elektrischen Schutzschaltern angewandt, um ein- und mehrpolige elektrische Verbraucher vor unzulässigen Betriebszuständen zu schützen. Diese Schutzschalter können Leistungsschalter, Motorschutzschalter und Leitungsschutzschalter sein. Sie müssen Überströme je nach geltender Vorschrift innerhalb bestimmter Ansprechgrenzen abschalten. Zu diesem Zweck sind die Stromauslöser mit den zu öffnenden Kontakten der Schutzschalter dahingehend' gekoppelt, daß sie diese als Reaktion auf einen Überstrom- bzw. Kurzschlußstrom öffnen und ggf. offenhalten. Gemäß FIG 2 sind solche Stromauslöser 1 aus einer Magnetspule 2, einem Spulengestell 3 mit einer Führungsröhre 4, einem beweglichen Anker 5, einem ortsfesten Magnetkern 6, einer Feder 7 und einer Stromanschlußklemme 8 zusammengesetzt. Das Spulengestell 3 mit der Führungsröhre 4 besteht aus isolierendem Material. Um das Spulengestell 3 ist die Magnetspule 2 aufgewickelt oder aufgesteckt. Der in der Führungsröhre 4 beweglich gelagerte Anker 5 bewegt sich entgegen der Federkraft der Feder 7 als Reaktion auf einen Überstrom- bzw. Kurzschlußstrom. Hierdurch wird über entsprechende mechanische Koppelglieder ein Öffnen der in der Strombahn befindlichen Kontakte erreicht. In die Führungsröhre 4 des Spulengestells 3 oder in die Anschluß-Generic electromagnetic current releases according to FIG 2 are used to detect overcurrents, in particular short-circuit currents, in conventional electrical circuit breakers in order to protect single- and multi-pole electrical consumers from impermissible operating conditions. These circuit breakers can be circuit breakers, motor circuit breakers and line circuit breakers. They must switch off overcurrents within certain response limits depending on the applicable regulations. For this purpose, the current releases are coupled to the contacts of the circuit breakers that are to be opened in such a way that they open them in response to an overcurrent or short-circuit current and, if necessary, keep them open. According to FIG 2, such current releases 1 are composed of a magnetic coil 2, a coil frame 3 with a guide tube 4, a movable armature 5, a stationary magnetic core 6, a spring 7 and a current connection terminal 8. The coil frame 3 with the guide tube 4 is made of insulating material. The magnetic coil 2 is wound or plugged onto the coil frame 3. The armature 5, which is movably mounted in the guide tube 4, moves against the spring force of the spring 7 as a reaction to an overcurrent or short-circuit current. This causes the contacts in the current path to open via appropriate mechanical coupling elements. In the guide tube 4 of the coil frame 3 or in the connection

klemme 8, wie in FIG 2 gezeigt, ist ein Magnetkern 6 eingepreßt. Der Magnetkern 6 ist ein Zusatzteil, das vorzugsweise im Inneren der Führungsröhre 4 gelagert ist, d.h. zumindest teilweise im Innenraum der Magnetspule 2. 5A magnetic core 6 is pressed into the terminal 8, as shown in FIG 2. The magnetic core 6 is an additional part which is preferably stored inside the guide tube 4, i.e. at least partially inside the magnetic coil 2. 5

Der Erfindung liegt die Aufgabe zugrunde, einen elektromagnetischen Stromauslöser der obengenannten Art teileminimiert und damit wirtschaftlich herzustellen.The invention is based on the object of producing an electromagnetic current release of the above-mentioned type with minimal parts and thus economically.

Die Aufgabe wird dadurch gelöst, daß der Magnetkern und die Stromanschlußklemme einstückig ausgeführt sind.The task is solved by the fact that the magnetic core and the power connection terminal are designed as a single piece.

Eine besonders kostengünstige Ausführungsform ist gegeben, wenn der Magnetkern und die Stromanschlußklemme als einstükkiges Stanzbiegeteil gefertigt sind.A particularly cost-effective embodiment is provided if the magnetic core and the power connection terminal are manufactured as a single-piece stamped and bent part.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail below with reference to a drawing.

FIG 1 einen erfindungsgemäßen Stromauslöser und FIG 2 eine Ausführung eines bekannten Stromauslösers.FIG 1 shows a current release according to the invention and FIG 2 shows an embodiment of a known current release.

Der elektromagnetische Stromauslöser 1 gemäß FIG 1 ist aus einer Magnetspule 2, einem Spulengestell 3 mit einer Führungsröhre 4 aus isolierendem Material, einem beweglichen Anker 5, einem ortsfesten Magnetkern 6, einer Feder 7 und einer Stromanschlußklemme 8 als wesentlichen Elementen zusammengesetzt. Die Magnetspule 2 ist um das Spulengestell aufgewikkelt oder darauf aufgesteckt und Bestandteil der Strombahn eines zu schützenden Verbrauchers. Der Anker 5 ist beweglich in der Führungsröhre 4 gelagert und reagiert auf einen Kurzschlußstrom. Die Bewegung des Ankers 5 bewirkt über entsprechende mechanische Koppelglieder ein Öffnen von in der Strombahn befindlichen Kontaktstellen. Dabei bewegt sich der Anker 5 gegen die Kraftwirkung einer ebenfalls in der FührungsröhreThe electromagnetic current release 1 according to FIG 1 is composed of a magnetic coil 2, a coil frame 3 with a guide tube 4 made of insulating material, a movable armature 5, a stationary magnetic core 6, a spring 7 and a current connection terminal 8 as essential elements. The magnetic coil 2 is wound around the coil frame or plugged onto it and is part of the current path of a consumer to be protected. The armature 5 is movably mounted in the guide tube 4 and reacts to a short-circuit current. The movement of the armature 5 causes contact points in the current path to open via corresponding mechanical coupling elements. The armature 5 moves against the force of a

4 gelagerten Feder 7. Um eine steilere Kraftkurve des Stromauslösers 1 zu erhalten, ist in der Führungsröhre 4 des Spulengestells 3 ein ortsfester Magnetkern 6 angeordnet, der zusammen mit einer Stromanschlußkleinme 8 für die Magnetspule 2 als einstückiges Teil gefertigt ist. Dieses Teil ist vorteilhafterweise als Stanzbiegeteil ausgeführt.4 mounted spring 7. In order to obtain a steeper force curve of the current release 1, a stationary magnetic core 6 is arranged in the guide tube 4 of the coil frame 3, which is manufactured as a single part together with a current connection small part 8 for the magnetic coil 2. This part is advantageously designed as a stamped and bent part.
