Aktivteileinheit eines Messwandlers und Messwandler Die Erfindung betrifft eine Aktivteileinheit eines Messwand¬ lers und einen Messwandler. Active subunit of a transducer and transducer The invention relates to an active subunit of a measuring wall ¬ coupler and a transducer.
Genauer betrifft die Erfindung als Spannungswandler ausgebildete Messwandler zum Messen elektrischer Spannungen und/oder zum Schutz vor hohen elektrischen Spannungen sowie Messwandler, die eine Kombination derartiger Spannungswandler mit Stromwandlern zum Messen elektrischer Ströme und/oder zum Schutz vor hohen elektrischen Strömen sind. Derartige Messwandler transformieren elektrische Spannungen und Ströme gemäß dem Prinzip eines Transformators und weisen dazu in der Regel ein Aktivteil mit einem Messwandlerkern und zwei unterschiedlichen Messwandlerwicklungen auf. Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Aktivteileinheit eines Messwandlers und einen verbesserten Messwandler anzugeben. More particularly, the invention relates to voltage transformers for measuring electrical voltages and / or for protection against high electrical voltages and transducers, which are a combination of such voltage transformers with current transformers for measuring electrical currents and / or for protection against high electrical currents. Such transducers transform electrical voltages and currents according to the principle of a transformer and, as a rule, have an active part with a transducer core and two different transducer windings. The invention has for its object to provide an improved active part unit of a transducer and an improved transducer.
Die Aufgabe wird erfindungsgemäß hinsichtlich der Aktivteil- einheit durch die Merkmale des Anspruchs 1 und hinsichtlich des Messwandlers durch die Merkmale des Anspruchs 9 gelöst. The object is achieved according to the invention with respect to the active part unit by the features of claim 1 and with respect to the transducer by the features of claim 9.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Advantageous embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Aktivteileinheit eines Messwandlers um- fasst einen Messwandlerkern, einen Pressrahmen, der wenigstens an zwei sich gegenüberliegenden Oberflächen des Messwandlerkerns anliegt, ein Wickelrohr, das einen Kernabschnitt des Messwandlerkerns umgibt und wenigstens eine Messwandler¬ wicklung trägt, und wenigstens eine Verdrehsicherung, die ei¬ ne das Wickelrohr mit dem Pressrahmen verbindende Aushärtungsmasse umfasst. Unter einer Aushärtungsmasse wird hier eine Masse aus einem fließfähigen oder formbaren Material verstanden, das von selbst oder durch eine äußere Beeinflussung aushärtet. An active part unit of the invention a transducer environmentally summarizes a transducer core, a pressing frame which rests at least on two opposite surfaces of the transducer core, a winding tube which surrounds a core portion of the transducer core and carrying at least one transducer ¬ winding, and at least one anti-rotation device, the egg ¬ ne comprises the winding tube with the pressing frame connecting curing mass. Under a curing composition is understood here a mass of a flowable or moldable material that cures by itself or by an external influence.
Durch die wenigstens eine Verdrehsicherung werden Bewegungen des Wickelrohrs und von ihm getragener Bauteile relativ zu dem Pressrahmen verhindert. Dadurch werden vorteilhaft Schä¬ digungen von Komponenten des Messwandlers infolge solcher Be- wegungen vermieden. Die Realisierung einer Verdrehsicherung mit einer das Wickelrohr mit dem Pressrahmen verbindenden Aushärtungsmasse vermeidet vorteilhaft weitere Bauteile zur Vermeidung von Verdrehungen des Wickelrohrs, vereinfacht die Montage der Aktivteileinheit und vermeidet aufwändige und kostenintensive Bearbeitungen von Bauteilen. Ferner könnenBy the at least one anti-rotation movements of the winding tube and components supported by it are prevented relative to the pressing frame. This Schä ¬ endings of components of the transducer to avoid movements due to such loading beneficial. The realization of an anti-rotation device with a winding tube connecting the winding tube with the pressing frame advantageously avoids further components to prevent twisting of the winding tube, simplifies the assembly of the active part unit and avoids complex and costly machining of components. Furthermore, can
Fertigungstoleranzen der Bauteile der Aktivteileinheit durch eine Aushärtungsmasse in einfacher Weise ausgeglichen werden. Außerdem kann die Aushärtung der Aushärtungsmasse beispiels¬ weise nach dem Abschluss von Montagearbeiten in einem Zwi- schenlagerungszustand der Aktivteileinheit oder des Messwand¬ lers erfolgen, ohne weitere Ressourcen zu beanspruchen. Manufacturing tolerances of the components of the active part unit can be compensated by a curing mass in a simple manner. In addition, the curing of the Aushärtungsmasse can ¬ example, after the completion of assembly work in an intermediate storage condition of the active entity or the measuring wall ¬ toddlers done without consuming more resources.
Eine Ausgestaltung der Erfindung sieht vor, dass jede Verdrehsicherung eine in dem Pressrahmen gebildete Pressrahmen- tasche umfasst, in die ein Randbereich des Wickelrohrs hin¬ einragt und in der dieser Randbereich des Wickelrohrs durch Aushärtungsmasse, die den Randbereich des Wickelrohrs in der Pressrahmentasche umgibt, fixiert ist. Diese Ausgestaltung der Erfindung ermöglicht vorteilhaft, ei¬ ne Verdrehsicherung an einem durch eine Pressrahmentasche vorgegebenen Ort durch Einbringen von Aushärtungsmasse in die Pressrahmentasche zu realisieren. Beispielsweise ist jede Pressrahmentasche als eine Ausnehmung in dem Pressrahmen ausgebildet, die außenseitig von einem Ta¬ schenkragen berandet wird. Vorzugsweise weist dabei jeder Ta¬ schenkragen eine abgerundete Oberfläche auf. Die Berandung einer Pressrahmentasche durch einen Taschenkra¬ gen begrenzt die Pressrahmentasche und gibt eine Füllhöhe für die Aushärtungsmasse vor. Die Abrundung der Oberfläche des Taschenkragens vermeidet vorteilhaft Kanten, an denen hohe Feldstärken elektrischer Felder entstehen können, die zu elektrischen Entladungen führen können. An embodiment of the invention provides that each rotation comprises a press frame pocket formed in the press frame, in which an edge region of the winding tube toward ¬ protrudes, and in this edge region of the winding tube by Aushärtungsmasse which surrounds the edge region of the roller tube in the press frame pocket fixed, is. This embodiment of the invention advantageously allows, egg ¬ ne rotation at a predetermined place by a press frame bag by introducing Aushärtungsmasse to realize in the press frame pocket. For example, each press frame case is formed as a recess in the press frame, which is externally bounded by a Ta ¬'s collar. Preferably has any Ta ¬ rule collar has a rounded surface. The boundary of a press frame bag by a Taschenkra ¬ gen limits the press frame bag and is a fill line for the Aushärtungsmasse ago. The rounding of the surface of the pocket collar advantageously avoids edges at which high field strengths of electric fields can arise, which can lead to electrical discharges.
Eine Weitergestaltung der vorgenannten Ausgestaltungen der Erfindung sieht vor, dass jeder in eine Pressrahmentasche hineinragende Randbereich des Wickelrohrs wenigstens eine Rohraussparung aufweist. A further embodiment of the aforementioned embodiments of the invention provides that each edge region of the winding tube projecting into a press frame pocket has at least one pipe recess.
Durch die Rohraussparungen wird die von Aushärtungsmasse um- gebene Oberfläche des Wickelrohrs vergrößert und damit die Stabilität der Verdrehsicherung erhöht. By means of the tube recesses, the surface of the winding tube surrounded by hardening compound is increased and thus the stability of the anti-twist device is increased.
Weitere Ausgestaltungen der Erfindung sehen vor, dass jedes Wickelrohrende des Wickelrohrs durch wenigstens eine Verdreh- Sicherung mit dem Pressrahmen verbunden ist, und/oder dass wenigstens ein Wickelrohrende des Wickelrohrs durch zwei Ver¬ drehsicherungen mit dem Pressrahmen verbunden ist. Further embodiments of the invention provide that each roller tube end of the winding tube is connected by at least one torsional fuse to the press frame, and / or that at least one roller tube end of the winding tube is connected by two Ver ¬ rotating fuses with the press frame.
Dadurch wird die Stabilität der Verbindung des Wickelrohrs mit dem Pressrahmen durch mehrfache, beidseitige und/oder einseitige Verdrehsicherungen erhöht. As a result, the stability of the connection of the winding tube to the pressing frame is increased by multiple, both-sided and / or one-sided anti-rotation.
Die Aushärtungsmasse ist beispielsweise ein Gießharz oder Zweikomponenten-Kunststoff . The curing compound is, for example, a cast resin or two-component plastic.
Gießharze und Zweikomponenten-Kunststoffe eignen sich insbe¬ sondere aufgrund ihrer Vergießfähigkeit, Stabilität nach dem Aushärten und kommerziellen Verfügbarkeit als Aushärtungsmas¬ sen . Casting resins and two-component plastics are in particular ¬ special because of their Vergießfähigkeit, stability after curing and commercial availability as Aushärtungsmas ¬ sen.

Die Schenkelenden jedes Schenkels sind zur Befestigung des Press- rahmens 35 in dem Gehäusekopf 5 des Messwandlers 1 ausgebil¬ det. In dem dargestellten Ausführungsbeispiel weist jede Pressrahmenhälfte 35.1, 35.2 dazu an jedem Schenkelende eine Verbindungsöffnung 47 auf, durch die ein Verbindungselement, beispielsweise eine Schraube, zur Befestigung des Schenkelen¬ des an einer korrespondierenden Rahmenhalterung 49 des Gehäusekopfes 5 (siehe Figur 1) geführt wird. The pressing frame 35 is U-shaped with two mutually parallel legs and a leg connecting the two legs formed. The pressing frame 35 consists of two pressing frame halves 35.1, 35.2, which each form one half of each leg and of the leg connection and lie on different sides of a plane of symmetry in which the pressing frame halves 35.1, 35.2 abut one another. The leg ends of each leg are used to attach the press frame 35 in the housing head 5 of the transducer 1 ausgebil ¬ det. In the illustrated embodiment, each press frame half 35.1, 35.2 thereto at each leg end to a connection opening 47, through which a connecting element, such as a screw, for fixing the Schenkelen ¬ of a corresponding frame holder 49 of the housing head 5 (see Figure 1) is performed.
Zur Befestigung des Pressrahmens 35 an dem Messwandlerkern 33 und zum Verspannen der Blechlamellen des Messwandlerkerns 33 sind mehrere Spannelemente 51 durch den Messwandlerkern 33 und die beiden Pressrahmenhälften 35.1, 35.2 geführt. Dabei ist jedes Spannelement 51 stabartig ausgebildet und weist we¬ nigstens ein durch eine Pressrahmenhälfte 35.1, 35.2 geführ- tes Ende auf, auf das eine Schraubenmutter 53 zum Anpressen der Pressrahmenhälfte 35.1, 35.2 an den Messwandlerkern 33 geschraubt ist. To fix the pressing frame 35 to the measuring transducer core 33 and to clamp the laminations of the measuring transducer core 33, a plurality of clamping elements 51 are guided through the measuring transducer core 33 and the two pressing frame halves 35.1, 35.2. In this case, each clamping member 51 is rod-like and has on we ¬ nigstens a geführ- by a press frame half 35.1, 35.2 tes end onto which a nut 53 is screwed to the transducer core 33 35.2 for pressing the pressing frame half 35.1.
