Abstract

The arrangement has current transformers (2) combined in a housing (1). A common-transfer conductive plate (4) is provided for wiring between the current transformers and an electronic actuator. The conductive plate has a U-shaped section provided with conductive paths (5). Coils (3) of the current transformers are partially held in free spaces of the U-shaped section of the conductive plate. The conductive plate rests at side pieces of the U-shaped section on iron cores (6) of the current transformers. The plate is suspended on an electrical connection pin (7) of the coils.

Description

Die Erfindung betrifft eine Anordnung mit mehreren Stromwandlern, die jeweils zur Stromversorgung eines zugehörigen elektronischen Auslösers eines Schaltgeräts dienen, wobei die Stromwandler in einem Gehäuse zusammengefasst sind und für die Verdrahtung zwischen dem jeweiligen Stromwandler und dem zugehörigen elektronischen Auslöser eine einzige Gesamt-Transferleiterplatte vorgesehen ist.The The invention relates to an arrangement with a plurality of current transformers, the each for the power supply of an associated electronic release of a switchgear serve, wherein the current transformers are combined in a housing and for the wiring between the respective current transformer and the associated electronic trigger a single overall transfer board is provided.

Eine derartige Anordnung ist bei Schaltgeräten in der industriellen Praxis bekannt. Für jeden Strompfad wird zur Messwertaufnahme und Energieversorgung ein Stromwandler benötigt, die jeweils aus Handlingsgründen als Set ausgeführt sind. Die Verdrahtung zur Auslöseeinheit erfolgt dabei über Leitungen oder über Transferleiterplatten. Bei Ausführungen mit Transferleiterplatte wird bisher die Leiterplatte auf die eingehausten Stromwandler oder innerhalb des Gehäuses auf die Spulen aufgesetzt. Dadurch wird die Wandlersetabmessung in Richtung der Hauptstrombahnen um die Dicke der Leiterbahn und um den Offset durch Lötungen und Überstände durch Anschlussstifte vergrößert. Dies vergrößert die Schalterhöhe, die gemäß Kundenanforderungen möglichst gering gehalten werden soll.A Such arrangement is in switching devices in industrial practice known. For every rung becomes a measurement and power supply a current transformer is needed, each for handling reasons executed as a set are. The wiring to the trip unit takes place via lines or over Transfer circuit boards. For versions with transfer board so far, the circuit board on the housed Current transformer or mounted inside the housing on the coils. Thereby the transducer set dimension changes in the direction of the main flow paths the thickness of the trace and offset by soldering and overhanging Terminal pins enlarged. This increases the height of the switch, the according to customer requirements as possible should be kept low.

Die DE 40 00 356 A1 und die DE 41 19 830 B4 offenbaren ein Schaltgerät mit jeweils mehreren Stromwandlern. Über Verbindungsstifte sind die Stromwandler mit einer gedruckten Schaltkarte verbunden, die eine elektronische Auslöseschaltung aufweist.The DE 40 00 356 A1 and the DE 41 19 830 B4 disclose a switching device with a plurality of current transformers. About connecting pins, the current transformers are connected to a printed circuit board having an electronic trigger circuit.

Der Erfindung liegt die Aufgabe zu Grunde, eine Anordnung der oben genannten Art vorzuschlagen, die möglichst geringe Abmessungen in Richtung der Schalterhöhe aufweist.Of the Invention is based on the object, an arrangement of the above Kind of suggest the possible has small dimensions in the direction of the switch height.

Die Aufgabe wird mit den Merkmalen nach Anspruch 1 gelöst.The The object is achieved with the features of claim 1.

Vorteilhafterweise liegt gemäß Anspruch 3 die Gesamt-Transferleiterplatte mit den Schenkeln der U-förmig ausgebildeten Abschnitte auf den Eisenkernen der Stromwandler auf.advantageously, is according to claim 3 shows the overall transfer circuit board with the legs of the U-shaped Sections on the iron cores of the current transformer.

Ein Ausführungsbeispiel der Erfindung wird im Folgenden anhand einer Zeichnung näher erläutert.One embodiment The invention will be explained in more detail below with reference to a drawing.

Die Figur zeigt eine Explosionsdarstellung einer erfindungsgemäßen Anordnung mit mehreren Stromwandlern 2.The figure shows an exploded view of an arrangement according to the invention with a plurality of current transformers 2 ,

Die Anordnung weist ein Gehäuse 1 mit drei Stromwandlern 2 zur Stromversorgung der hier nicht dargestellten elektronischen Auslöser eines dreiphasigen Schaltgerätes auf. Zur Verdrahtung der Stromwandler 2, d. h. der zugehörigen Spulen 3 mit den elektronischen Auslösern ist eine Gesamt-Transferleiterplatte 4 vorgesehen. Die Gesamt-Transferleiterplatte 4 weist für jeden Stromwandler 2 einen U-förmig ausgebildeten Abschnitt mit darin verlaufenden Leiterbahnen 5 auf. In den Freiräumen der U-förmig ausgebildeten Abschnitte der Gesamt-Transferleiterplatte 4 ist jeweils die Spule 3 einer der Stromwandler 2 zumindest teilweise aufgenommen. Die Gesamt-Transferleiterplatte 4 liegt mit den Schenkeln der U-förmig ausgebildeten Abschnitte auf den Eisenkernen 6 der Stromwandler 2 auf. Die Gesamt-Transferleiterplatte 4 ist auf elektrische Anschlussstifte 7 der Spulen 3 aufgeschoben und hierdurch mit diesen kontaktiert. Nach Abdeckung mit einem Deckel 8 ist die gesamte Anordnung berührungssicher gekapselt und nur noch die Anschlüsse 8 zur Verbindung mit den elektronischen Auslösern ragen aus dem Gehäuse 1 heraus.The arrangement has a housing 1 with three current transformers 2 to power the electronic triggers not shown here, a three-phase switching device on. For wiring the current transformers 2 , ie the associated coils 3 with the electronic releases is a total transfer PCB 4 intended. The overall transfer board 4 points for each current transformer 2 a U-shaped section with therein conductor tracks 5 on. In the free spaces of the U-shaped sections of the overall transfer circuit board 4 is each the coil 3 one of the current transformers 2 at least partially included. The overall transfer board 4 lies with the legs of the U-shaped sections on the iron cores 6 the current transformer 2 on. The overall transfer board 4 is on electrical connection pins 7 the coils 3 deferred and thus contacted with these. After covering with a lid 8th the entire arrangement is encapsulated safe to touch and only the connections 8th to connect to the electronic releases protrude from the housing 1 out.
