Description

Die Erfindung betrifft einen Aufnahmebehälter nach dem Oberbegriff des Anspruches 1, sowie einen Wandler nach dem Oberbegriff des Anspruches 5.The invention relates to a receptacle according to the preamble of claim 1 and a transducer according to the preamble of claim 5.

Derartige Aufnahmebehälter dienen in erster Linie dazu, den Wandler gegen Beschädigung zu schützen.Such receptacles primarily serve to protect the converter against damage.

Probleme bestehen darin, den Wandler mit dem Aufnahmebehälter mit der Primär- und Sekundärwicklung zu versehen. Zum Durchstecken der Primärwicklung besitzt der Aufnahmebehälter in seinem mittleren Bereich einen Durchbruch, und gleichzeitig muß durch diesen Durchbruch auch die Sekundärwicklung hindurchgefädelt werden.Problems are to provide the transducer with the primary and secondary winding receptacle. To insert the primary winding, the receptacle has an opening in its central area, and at the same time the secondary winding must also be threaded through this opening.

Aufgabe der Erfindung ist es, einen Aufnahmebehälter der eingangs genannten Art zu schaffen, bei dem dieses erheblich vereinfacht ist. Weiterhin soll ein Wandler unter Verwendung des Aufnahmebehälters geschaffen werden.The object of the invention is to provide a receptacle of the type mentioned, in which it is considerably simplified. Furthermore, a converter is to be created using the receptacle.

Diese erste Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale des Anspruches 1.This first object is achieved according to the invention by the characterizing features of claim 1.

Danach besitzt der Aufnahmebehälter einen Innenkörper, der durch eine axial verlaufende Wandung gebildet ist, die bei eingestecktem Wandler von dem Wandler umfaßt wird. Im Bereich der Mittelachse des Aufnahmebehälters und damit auch der Wandung ist eine den Innenkörper axial durchdringende Bohrung vorgesehen, die mit dem übrigen Bereich des Aufnahmebehälters, also mit dem Bereich, den der Wandlerkern einnimmt, keine Verbindung besitzt. Beidseitig zur Wandung ist der Boden innerhalb des durch den Innendurchmesser des Kern bestimmten Zylinderbereich mit Durchbrechungen versehen.Thereafter, the receptacle has an inner body which is formed by an axially extending wall which is enclosed by the transducer when the transducer is inserted. In the area of the central axis of the receptacle and thus also the wall, a bore axially penetrating the inner body is provided, which has no connection with the remaining area of the receptacle, that is to say with the area which the transducer core occupies. The bottom is provided with openings on both sides of the wall within the cylinder area determined by the inner diameter of the core.

Die Bohrung dient zum Durchstecken von Sekundärwicklungen und die Durchbrechungen im Boden des Aufnahmebehälters zum Durchstecken der Primärwicklung, wobei natürlich die Möglichkeit besteht, auch durch diese Durchbrechung Sekundärwicklungdraht hindurchzuführen.The bore serves to push through secondary windings and the openings in the bottom of the receptacle for pushing through the primary winding, with the possibility of passing secondary winding wire through this opening, of course.

Nach einer besonders vorteilhaften Ausgestaltung der Erfindung kann der Innenkörper eine senkrecht zur Wandung ebenfalls axial verlaufende zusätzliche Wandung aufweisen, so daß beide Wandungen im Querschnitt ein Kreuz bilden. Dadurch wird die Führung des Kerns im Inneren des Aufnahmebehälters verbessert.According to a particularly advantageous embodiment of the invention, the inner body can have an additional wall that also extends axially perpendicular to the wall, so that both walls form a cross in cross section. This improves the guidance of the core inside the receptacle.

Man könnte auch sagen, daß senkrecht zur Wandung beidseitig zwei Wandungsabschnitte angeformt sind, die mit der Wandung das Kreuz bilden. Selbstverständlich befindet sich im Zentrum des Kreuzes die Bohrung zum Durchstecken von Wicklungsdraht.One could also say that two wall sections are formed perpendicular to the wall on both sides, which form the cross with the wall. Of course there is a hole in the center of the cross for inserting winding wire.

Nach einer weiteren Ausgestaltung der Erfindung können die Wandung bzw. die beiden Wandungen oder Wandungsabschnitte von einem an den Boden und die axialen Endkanten der Wandungen anschließenden Zylinderkörper umgeben sein. Dadurch ist eine Anordnung des Aufnahmebehälters mit einer Doppelwandung hergestellt, und in den Ringraum wird der Wandlerkern eingesetzt.According to a further embodiment of the invention, the wall or the two walls or wall sections be surrounded by a cylinder body adjoining the bottom and the axial end edges of the walls. This creates an arrangement of the receptacle with a double wall, and the transducer core is inserted into the annular space.

Nach einer weiteren Ausgestaltung der Erfindung kann entsprechend den Ansprüchen 4, 5 und/oder 6 auf der Außenfläche der Außenwand des Aufnahmebehälters eine der Anzahl der Windungen der Primär- und Sekundärwicklungen entsprechende Anzahl von axialen Rillen angeformt sein, deren Abmessungen den Durchmessern der ersten und zweiten Wicklungsdrähte angepaßt sind. Dadurch wird auch eine Verbesserung der Führung der Wicklungsdrähte auf der Außenseite des Aufnahmebehälters erreicht.According to a further embodiment of the invention, a number of axial grooves corresponding to the number of turns of the primary and secondary windings, the dimensions of which correspond to the diameters of the first and second, can be formed on the outer surface of the outer wall of the receptacle according to claims 4, 5 and / or Winding wires are adjusted. This also improves the guidance of the winding wires on the outside of the receptacle.

Ein nach der Erfindung hergestellter Wandler für einen Fehlerstromschutzschalter ist dem Anspruch 7 zu entnehmen.A converter for a residual current circuit breaker manufactured according to the invention can be found in claim 7.

Anhand der Zeichnung, in der einige Ausführungsbeispiele der Erfindung dargestellt sind, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung näher erläutert und beschrieben werden.The invention and further advantageous refinements and improvements of the invention are to be explained and described in more detail with reference to the drawing, in which some exemplary embodiments of the invention are shown.

Die Figur 1 zeigt eine Querschnittsansicht eines Aufnahmebehälters 10, der eine zylindrische Außenwand 11 und eine zyindrische Innenwand 12 aufweist, die in einem Abstand zueinander angeordnet sind, der der radialen Dicke eines Wandlerkerns 14 entspricht. Die Außen- und die Innenwand 11 bzw. 12 sind mittels eines eine im Längsschnitt halbkreisförmige, umlaufende Rinne bildenden Bodens 13 miteinander verbunden, so daß der zwischen der Außen- und der Innenwand 11 und 12 gebildete Ringraum 15 nach einer Seite (in der Figur 2 nach der linken Seite) geschlossen ist. Nach der anderen Seite (in Figur 2 die rechte Seite) ist der Ringraum 15 offen und mittels eines torusförmigen Ringelementes 16 verschlossen. Das Ringelement 16 besitzt auf einer Seite seiner Ebene einen leistenförmigen Vorsprung 17, der in den Raum zwischen Außen- und Innenwand teilweise eingreift, so daß das Ringelement dort gehalten ist. Die auf der dem Vorsprung entgegengesetzten Seite gelegene Kontur 18 des Ringelements 16 ist im Querschnitt kreisbogenförmig.FIG. 1 shows a cross-sectional view of a receptacle 10 which has a cylindrical outer wall 11 and a cylindrical inner wall 12 which are arranged at a distance from one another which corresponds to the radial thickness of a transducer core 14. The outer and inner walls 11 and 12 are connected to each other by means of a bottom 13 forming a semicircular, circumferential groove, so that the annular space 15 formed between the outer and inner walls 11 and 12 is to one side (in FIG. 2 to the left) is closed. On the other side (the right side in FIG. 2), the annular space 15 is open and closed by means of a toroidal ring element 16. The ring element 16 has on one side of its level a strip-shaped projection 17 which partially engages in the space between the outer and inner wall, so that the ring element is held there. The contour 18 of the ring element 16 located on the side opposite the projection has a circular arc shape in cross section.

Innerhalb der Innenwand 12 befinden sich kreuz- oder speichenförmig einander zugeordnete Wandungen 19 und 20, die an einen eine Bohrung 21 umschließenden Innenzylinder 22 angeschlossen sind, wodurch der Innenzylinder 22 über die beiden Wandungen 19 und 20 mit der Innenwand 12 verbunden ist. Die Abschnitte 23, 24, 25 und 26 sind, wie aus Figur 1 und 2 ersichtlich ist, offen.Inside the inner wall 12 are cross-shaped or spoke-shaped walls 19 and 20 which are connected to an inner cylinder 22 surrounding a bore 21, whereby the inner cylinder 22 is connected to the inner wall 12 via the two walls 19 and 20 is. The sections 23, 24, 25 and 26 are, as can be seen from Figures 1 and 2, open.

Die Anordnung nach den Figuren 1 und 2 ist noch zu ergänzen durch die Primär- und Sekundärwicklungen (nicht dargestellt). Beispielsweise kann die Sekundärwicklung durch die Bohrung 21 hindurchgefädelt werden, wogegen die Primärwicklungen je nach Phase durch die Durchbrechungen 23, 24, 25 und 26 hindurchgefädelt werden, und zwar dergestalt, daß beispielsweise durch die Durchbrechung 23 ein Nulleiter, durch die Durchbrechung 24 ein L₁-Leiter, durch die Durchbrechung 25 ein L₂-Leiter und durch die Durchbrechung 26 ein L₃-Leiter hindurchgefädelt sein kann.The arrangement according to FIGS. 1 and 2 is to be supplemented by the primary and secondary windings (not shown). For example, the secondary winding can be threaded through the bore 21, whereas the primary windings are threaded through the openings 23, 24, 25 and 26, depending on the phase, in such a way that, for example, through the opening 23 a neutral conductor, through the opening 24 a L₁- Conductor, an L₂ conductor can be threaded through the opening 25 and an L₃ conductor can be threaded through the opening 26.

Die Figur 3 zeigt eine weitere Ausgestaltung der Erfindung.FIG. 3 shows a further embodiment of the invention.

Der Aufnahmebehälter 30 besitzt eine Außenwand 31, die an einem Ende (in Figur 4 dem linken Ende) mit einem radial nach innen vorspringenden bordartigen Boden 32 abgeschlossen ist. Der Boden 32 besitzt eine in ihrer Gesamtheit mit der Bezugsziffer 33 bezeichnete Durchbrechung, die durch den Wandungen 19 und 20 entsprechende Wandungen 34 und 35 unterteilt ist; die Wandungen 34 und 35 verlaufen vom Boden 32 aus in axialer Richtung bis hin zum freien Ende der Außenwand 31. Weiterhin schließen die Wandungen 34 und 35 an einem Innenzylinder 36 an, der eine Bohrung 37 umgibt, die der Bohrung 21 entspricht. Eine Innenwand wie die Innenwand 12 ist bei der Anordnung nach Figur 3 und 4 weggelassen. Darüberhinaus sind Durchbrechungsabschnitte 38, 39, 40 und 41 vorgesehen, die den Durchbrechungen 23 bis 26 entsprechen. Zur Abdeckung ist ein Ringelement 42 vorgesehen, welches dem Ringelement 16 gleicht. Lediglich der Innendurchmesser des Ringelementes 42 ist durch einen Zylinder 43 gebildet, der exakt die Wandungen 34 und 35 umgibt.The receptacle 30 has an outer wall 31 which is closed at one end (the left end in FIG. 4) with a radially inwardly projecting rim 32. The bottom 32 has an opening, designated in its entirety with the reference number 33, which is divided by the walls 19 and 20 corresponding walls 34 and 35; the walls 34 and 35 extend from the bottom 32 in the axial direction up to the free end of the outer wall 31. Furthermore, the walls 34 and 35 adjoin an inner cylinder 36 which surrounds a bore 37 which corresponds to the bore 21. An inner wall like the inner wall 12 is omitted in the arrangement according to FIGS. 3 and 4. In addition, perforation sections 38, 39, 40 and 41 are provided, which correspond to the openings 23 to 26. A ring element 42 is provided for covering, which is similar to the ring element 16. Only the inside diameter of the ring element 42 is formed by a cylinder 43 which exactly surrounds the walls 34 and 35.

Die Figur 5 zeigt eine Aufsicht von unten auf den Aufnahmebehälter gemäß Figur 3 mit eingezeichneten Primär- und Sekundärwicklungen 51 und 52. Man erkennt, daß die Primärwicklungen 51 durch die Durchbrüche 38 bis 41 gefädelt werden, wogegen die Sekundärwicklungen 52 durch die Bohrung 37 gefädelt ist.FIG. 5 shows a top view of the receptacle according to FIG. 3 with the primary and secondary windings 51 and 52 shown. It can be seen that the primary windings 51 are threaded through the openings 38 to 41, whereas the secondary windings 52 are threaded through the bore 37 .

Auf der Außenfläche der Außenwand 31 sind axial verlaufende Vorsprünge 53, von denen nur acht dargestellt sind, vorgesehen, die Rillen 54 zwischen sich bilden und die zur Führung von Primär- und Sekundärwicklung dienen. Es ist natürlich auch möglich, lediglich die eingezeichneten, im Winkel von je 90° verteilt angeordneten Vorsprünge 53 nur für die Sekundärwicklung vorzusehen. Die Primärwicklungsdrähte 51 sind dann an der Außenfläche nicht geführt.On the outer surface of the outer wall 31, axially extending projections 53, of which only eight are shown, are provided, which form grooves 54 between them and which serve to guide the primary and secondary windings. It is of course also possible to provide only the projections 53 shown, which are distributed at an angle of 90 °, only for the secondary winding. The primary winding wires 51 are then not guided on the outer surface.

Der gesamte Außendurchmesser der gesamten Anordnung mit aufgebrachter Primärwicklung 51 ist d₁.The entire outer diameter of the entire arrangement with an applied primary winding 51 is d 1.

Die Figur 6 zeigt die beiden Leisten 53 und die dazwischen befindliche Rille 54.FIG. 6 shows the two strips 53 and the groove 54 located between them.
