Description

Magnetisch-thermisches überstromrelais Die Erfindung bezieht sich auf ein magnetisch-thermisches überstromrelais zur Auslösung von Installationsselbst- und Motorschutzschaltern.Magneto-thermal overcurrent relay The invention relates to to a magneto-thermal overcurrent relay for triggering installation self- and motor protection switches.

Derartige Relais sind in mannigfacher Ausführung bekannt. Man hat die Relais für jeden Pol einzeln auf,der Schaltergrundplatte montiert. Man hat außerdem einen gleichzeitig das Magnetgestell der magnetischen Auslöser bildenden Rahmen verwendet, der die beispielsweise drei Elektromagneten und die drei thermischen Auslöser trägt. Man hat auch ,die drei einzelnen Magnetsysteme durch eine Spritzgußmasse zu einer Einheit verbunden. Die letztgenannten Ausführungen haben vor der ersterwähnten den Vorteil, daß der ganze Relaissatz eine Einheit bildet. Nachteilig ist bei :den letztgenannten Ausführungen einerseits -die magnetische Koppelung der drei Systeme, anderseits die in beiden Fällen vorhandene leitende Verbindung zwischen den drei Systemen, welche sich bei ,einem Körperschluß nachteilig auswirkt.Such relays are known in various designs. One has the relays for each pole individually on the switch base plate. You also have a frame that also forms the magnetic frame of the magnetic release used, for example, the three electromagnets and the three thermal Trigger carries. One also has the three individual magnet systems by means of an injection molding compound connected to one unit. The last-mentioned statements have preceded the first-mentioned the advantage that the whole relay set forms a unit. The disadvantage is: the the latter versions on the one hand - the magnetic coupling of the three systems, on the other hand, the conductive connection between the three that exists in both cases Systems that have an adverse effect on a body closure.

Die obenerwähnten Nachteile werden erfindungsgemäß dadurch vermieden, daß die drei einzelnen Magnetsysteme magnetisch und elektrisch vollkommen voneinander getrennt auf einer gleichzeitig die thermischen Auslöseglie,der tragenden, aus Isoliermaterial bestehenden Leiste befestigt werden. Dadurch. bilden auch die drei Systeme eine Einheit, ohne mit den Nachteilen. der bekannten Konstruktionen behaftet zu sein.The above-mentioned disadvantages are avoided according to the invention by that the three individual magnet systems magnetically and electrically completely separate from one another separated on one at the same time the thermal release element, the load-bearing, made of insulating material existing bar. Through this. the three systems also form one Unity without facing the disadvantages. to be afflicted with the known constructions.

In der Zeichnung ist die Erfindung in drei Ansichten dargestellt. Hierbei bedeuten 1 die vorzugsweise aus keramischen Material bestehende Isolierleiste, 211, 2b und 2c die drei Magnetsysteme mit den Magnetspulen 3a, 3b und 3c und dem Anker 4.. Die thermischen Auslöseglieder 5a, 5b und 5c sind mittels Schrauben 6 gehalten; diese Schrauben dienen gleichzeitig zur Befestigung der Magnetsysteme 2a, 2b und 2c auf der Leiste r.In the drawing, the invention is shown in three views. Here, 1 denotes the insulating strip, which is preferably made of ceramic material, 211, 2b and 2c the three magnet systems with the magnet coils 3a, 3b and 3c and the Armature 4 .. The thermal release elements 5a, 5b and 5c are fastened by means of screws 6 held; these screws are also used to fasten the magnet systems 2a, 2b and 2c on the r bar.

PATENTANSPRÜCHE: 1. Magnetisch-thermi.sches überstromrelais, bei welchem mehrere Einzelrelais zu einem Satz vereinigt sind, dadurch gekennzeichnet, daß sowohl die -Magnet-Systeme (2a, 2b, 2c) als auch die thermischen Auslöseglieder (5a, 5b, 5c) dadurch zu einem Bauteil vereinigt sind, daß die als Träger für die thermischen Auslöseglieder dienende, vorzugsweise aus keramischem Baustoff bestehende Isolierleiste (1) gleichzeitig auch die Magnetsysteme trägt. PATENT CLAIMS: 1. Magnetic-thermal overcurrent relay, in which several individual relays are combined into a set, characterized in that both the magnet systems (2a, 2b, 2c) and the thermal release elements (5a, 5b, 5c) are combined in one component in that the insulating strip (1), which is used as a carrier for the thermal release elements and preferably consists of ceramic building material, also carries the magnet systems at the same time. 2. Überstromrelais nach Anspruch 1, dadurch gekennzeichnet, daß die Magnetsysteme (2a, 2b, 2c) gleichzeitig mit den die thermischen Auslöseglieder (5a, 5b, 5c) haltenden Schrauben (b) befestigt sind. Zur Abgrenzung des Anmeldungsgegenstandes vom Stand der Technik sind im Erteilungsverfahren in Betracht gezogen worden: deutsche Patentschrift Nr. 554403, 677424; französische Patentschrift Nr. 804953, 839 053; Ernst Besag, Erden, Nullen, Schutzschalten. 1926l27, Verlag G. Braun, Karlsruhe (Baden), S. 31 bis 35.2. Overcurrent relay according to claim 1, characterized in that the magnet systems (2a, 2b, 2c) are fastened simultaneously with the screws (b) holding the thermal release elements (5a, 5b, 5c). To distinguish the subject of the application from the state of the art, the following were considered in the granting procedure: German patent specification No. 554403, 677424; French Patent No. 804953, 839 053; Ernst Besag, grounding, zeros, protective switching. 1926l27, G. Braun Verlag, Karlsruhe (Baden), pp. 31 to 35.
