The first curing compound enables the Compensation of manufacturing and assembly tolerances of the voltage transformer core and the mounting plates and thereby improves the connection between the voltage transformer core and the mounting plates.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass der Plattenrand eine Randaussparung aufweist, die mit der ersten Aushärtungsmasse ausgefüllt ist. Diese Ausgestaltung der Erfindung erleichtert vorteilhaft ein Einbringen der ersten Aushärtungsmasse und vergrößert gleichzeitig vorteilhaft den von der ersten Aushärtungsmasse bedeckten Oberflächenbereich einer Befestigungsplatte.Another embodiment of the invention provides that the edge of the plate has an edge recess which is filled with the first curing compound. This embodiment of the invention advantageously facilitates the introduction of the first hardening compound and at the same time advantageously increases the surface area of a fastening plate covered by the first hardening compound.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass wenigstens eine Befestigungsplatte an einem an den ersten Kernabschnitt grenzenden Endbereich des zweiten Kernabschnitts angeordnet ist. Durch die Anordnung einer Befestigungsplatte an einem Endbereich des zweiten Kernabschnitts kann die Befestigungsplatte vorteilhaft Verschiebungen des Spannungswandlerkerns in zwei Richtungen entgegenwirken, so dass insgesamt weniger Befestigungsplatten vorgesehen werden müssen, um Verschiebungen des Spannungswandlerkerns zu verhindern.Another embodiment of the invention provides that at least one fastening plate is arranged on an end region of the second core section adjoining the first core section. By arranging a fastening plate at an end region of the second core section, the fastening plate can advantageously counteract displacements of the voltage transformer core in two directions, so that overall fewer fastening plates have to be provided in order to prevent displacements of the voltage transformer core.
Eine weitere Ausgestaltung der Erfindung sieht eine U-förmige elektrische Abschirmung vor, die an einer von dem Anliegebereich der Gehäuseinnenseite abgewandten Seite des zweiten Kernabschnitts entlang einer U-förmigen Innenkante des zweiten Kernabschnitts angeordnet ist. Eine derartige Abschirmung schirmt vorteilhaft das von dem Spannungswandlerkern erzeugte elektrische Feld auf dessen von dem Anliegebereich abgewandten Seite im Bereich seiner Innenkante ab.Another embodiment of the invention provides a U-shaped electrical shield which is arranged on a side of the second core section facing away from the contact area of the inside of the housing along a U-shaped inside edge of the second core section. Such a shield advantageously shields the electrical field generated by the voltage transformer core on its side facing away from the contact area in the area of its inner edge.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass das Aktivteil ein Wickelrohr aufweist, das den ersten Kernabschnitt des Spannungswandlerkerns umgibt und wenigstens eine Spannungswandlerwicklung trägt und mit wenigstens einer Befestigungsplatte verdrehsicher, beispielsweise durch eine zweite Aushärtungsmasse, verbunden ist. Gemäß dieser Ausgestaltung der Erfindung bewirkt wenigstens eine Befestigungsplatte zusätzlich eine Verdrehsicherung des Wickelrohrs. Durch die Verdrehsicherung werden Bewegungen des Wickelrohrs und von ihm getragener Bauteile relativ zu dem Spannungswandlerkern verhindert. Dadurch werden vorteilhaft Schädigungen von Komponenten der Spannungswandlereinheit infolge solcher Bewegungen vermieden. Die Realisierung einer Verdrehsicherung mit einer das Wickelrohr mit einer Befestigungsplatte verbindenden Aushärtungsmasse vermeidet vorteilhaft weitere Bauteile zur Vermeidung von Verdrehungen des Wickelrohrs, vereinfacht die Montage der Spannungswandlereinheit und vermeidet aufwändige und kostenintensive Bearbeitungen von Bauteilen. Ferner können Fertigungstoleranzen des Wickelrohrs und der Befestigungsplatte durch die zweite Aushärtungsmasse in einfacher Weise ausgeglichen werden.Another embodiment of the invention provides that the active part has a wound tube that surrounds the first core section of the voltage converter core and carries at least one voltage converter winding and is connected to at least one mounting plate in a torsion-proof manner, for example by a second curing compound. According to this configuration According to the invention, at least one fastening plate additionally prevents the winding tube from rotating. The anti-twist device prevents movements of the winding tube and the components carried by it relative to the voltage transformer core. This advantageously prevents damage to components of the voltage converter unit as a result of such movements. The implementation of an anti-rotation device with a curing compound connecting the winding tube to a mounting plate advantageously avoids further components to avoid twisting of the winding tube, simplifies the assembly of the voltage converter unit and avoids complex and cost-intensive processing of components. Furthermore, manufacturing tolerances of the winding tube and the fastening plate can be compensated for in a simple manner by the second curing compound.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass das Wickelrohr wenigstens eine Wickelrohrausnehmung aufweist, und dass eine Befestigungsplatte eine Verbindungsnase aufweist, die in die Wickelrohrausnehmung hineinragt, und dass die zweite Aushärtungsmasse die Verbindungsnase in der Wickelrohrausnehmung fixiert. Diese Ausgestaltung der Erfindung ermöglicht eine zuverlässige Realisierung einer Verdrehsicherung des Wickelrohrs durch ein Eingreifen einer Verbindungsnase einer Befestigungsplatte in eine Wickelrohrausnehmung.A further embodiment of the invention provides that the winding tube has at least one winding tube recess, and that a fastening plate has a connecting nose that protrudes into the winding tube recess, and that the second curing compound fixes the connecting nose in the winding tube recess. This embodiment of the invention enables a reliable implementation of a rotation lock of the winding tube by engaging a connecting nose of a fastening plate in a winding tube recess.
Ein erfindungsgemäßer Messwandler weist eine erfindungsgemäße Spannungswandlereinheit und ein Messwandlergehäuse, das eine Gehäuselängsachse aufweist, auf, wobei das Aktivteilgehäuse der Spannungswandlereinheit einen Teil des Messwandlergehäuses bildet. Der Anliegebereich der Gehäuseinnenseite des Aktivteilgehäuses ist dabei in einer zu der Gehäuselängsachse senkrechten Ebene angeordnet. Diese Anordnung des Anliegebereichs senkrecht zu der Gehäuselängsachse bewirkt eine "horizontale" Anordnung des Spannungswandlerkerns relativ zu der Gehäuselängsachse. Gegenüber einer "vertikalen" Anordnung des Spannungswandlerkerns werden dadurch vorteilhaft die Längsausdehnung und das Gewicht des Messwandlergehäuses reduziert.A transducer according to the invention has a voltage converter unit according to the invention and a transducer housing that has a housing longitudinal axis, the active part housing of the voltage converter unit forming part of the transducer housing. The contact area of the housing inner side of the active part housing is arranged in a plane perpendicular to the housing longitudinal axis. This arrangement of the contact area perpendicular to the housing longitudinal axis results in a "horizontal" arrangement of the voltage converter core relative to the housing longitudinal axis. Compared to a "vertical" arrangement of the The voltage transformer core thereby advantageously reduces the length and weight of the transducer housing.
