Abstract
Description
Der Erfindung liegt die Aufgabe zugrunde, einen mehrstufigen geschlossenen Ringkern hoher Festigkeit, insbesondere für einen Verteilungstransformator, welcher nach außen hin elektrisch isoliert ist zu bauen, sowie ein dafür rationelles Fertigungsverfahren zu realisieren.The invention has for its object to build a multi-stage closed ring core high strength, in particular for a distribution transformer, which is electrically insulated to the outside, and to realize a rational production process.
Die hohe Festigkeit der Ringkerne, mit einem Gewicht, von 100 kg bis über 2000 kg, wird notwendig, damit die dünnen Transformatorbleche formstabil bleiben, zum einen bei der Weiterverarbeitung, sowie im späteren Dauerbetrieb. Die elektrische Isolation wird benötigt, damit die Transformatorwicklung gegenüber dem Kern eine ausreichende Spannungsfestigkeit aufweist.The high strength of the ring cores, with a weight of 100 kg to over 2000 kg, is necessary so that the thin transformer sheets remain dimensionally stable, on the one hand during further processing, and later in continuous operation. The electrical insulation is required so that the transformer winding has a sufficient dielectric strength with respect to the core.
Es besteht weiter die Aufgabe, einen geschlossenen mehrstufigen Ringkerntransformatorkern hoher Festigkeit, welcher nach außen hin elektrisch isoliert ist, und ein dafür rationelles, maschinelles Herstellungsverfahren zu schaffen, damit die Produktion von Ringkernverteilungstransformatoren ermöglicht wird.It is a further object to provide a closed multistage toroidal core transformer core of high strength, which is electrically insulated to the outside, and an efficient, machine manufacturing process, so that the production of toroidal distribution transformers is made possible.
Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, dass ein dünnes magnetisch leitendes Material zu einem mehrstufigen geschlossenen Ringkerntransformatorkern gewickelt wird, sich zwischen dem magnetisch leitendem Material ein Klebstoff befindet, welcher das Material gegenseitig isoliert (zur Vermeidung von Wirbelströmen) und den Ringkern verfestigt und die elektrische Isolation gegenüber der Unterspannungswicklung mit Distanzringen oder Distanzstücken aus elektrisch nicht leitenden Material erlangt wird.The achievement of this task is that a thin magnetically conductive Material is wound into a multi-stage closed toroidal transformer core, between the magnetically conductive material is an adhesive which mutually isolated (to avoid eddy currents) and solidifies the toroidal core and the electrical insulation against the low voltage winding with spacers or spacers made of electrically non-conductive material is obtained.
Zur Steigerung der Festigkeit und zur elektrischen Isolation nach außen hin, kann der Ringkerntransformatorenkern mit einem elektrisch nicht leitenden Gießharz hoher Festigkeit komplett eingegossen werden.To increase the strength and electrical insulation to the outside, the toroidal transformer core can be completely cast with an electrically non-conductive casting resin high strength.
Eine weitere Ausführungsform sieht vor, dass die elektrische Isolation (Kern zur Unterspannungswicklung) durch mindestens drei Distanzringe oder jeweils drei Distanzstücke pro Windung, welche in den Stufungen des Ringkerns fest angebracht werden, realisiert wird. Anschließend wird der Ringkern mit einem Lack zur Isolation und zum Schutz gegen Korrosion überzogen.A further embodiment provides that the electrical insulation (core for undervoltage winding) is realized by at least three spacer rings or in each case three spacers per turn, which are fixedly mounted in the steps of the toroidal core. Subsequently, the toroidal core is coated with a varnish for insulation and protection against corrosion.
Für die Lösung des Ringkernwickelverfahrens wird ein Trägergestell zur Halterung der Vorrichtungen, für jede Breite des magnetisch leitendem Material mindestens eine Vorratsrollenvorrichtung, eine Antriebs -und Bremsvorrichtung, mit einer Führungsvorrichtung, einer Schneidevorrichtung und einer Klebstoffsprühvorrichtung, für jede Breite des magnetisch leitendem Materials mindestens eine Aufwickelvorrichtung mit einer Antriebs -und Bremsvorrichtung, sowie einer gemeinsamen Führungsschiene, benötigt.For the solution of the toroidal core winding method is a support frame for holding the devices, for each width of the magnetically conductive material at least one supply roll device, a drive and braking device, with a guide device, a cutting device and a Klebsprühervorrichtung, for each width of the magnetically conductive material at least one take-up device with a drive and brake device, as well as a common guide rail needed.
Der Wickelvorgang beginnt bei schmal, geht zu breit und wieder zu schmal. Die Wickelhöhe wird durch eine Fernmessvorrichtung überwacht. Bei erreichen des Sollwertes wird der Wickelvorgang für die entsprechende Breite beendet, das magnetisch leitende Material abgetrennt und auf der Führungsschiene der nächsten Breite zugeführt. Während des Aufwickelvorgangs wird das magnetisch leitende Material mit Klebstoff besprüht. Auf diese Art und Weise entsteht ein geschlossener Stufenringkern, welcher Klebstoff zur Isolation des magnetisch leitenden Materials aufweist und eine genügende Festigkeit zur Weiterverarbeitung besitzt. Für jede Breite des magnetisch leitenden Materials, mit Ausnahme des breitesten Materials, müssen zwei Vorratsrollen inklusive aller Vorrichtungen und zwei Aufwickelvorrichtungen inklusive aller Vorrichtungen entsprechend der Anzahl der Stufen des Ringkerns vorhanden sein. Im eingeschwungenen Zustand sind alle Vorratsrolleneinheiten, sowie alle Aufwickeleinheiten gleichzeitig in Betrieb.The winding process begins at a narrow, too wide and too narrow again. The winding height is monitored by a remote measuring device. When the setpoint value is reached, the winding process for the corresponding width is terminated, the magnetically conductive material is severed and supplied to the guide rail of the next width. During the winding process The magnetically conductive material is sprayed with adhesive. In this way, a closed stage ring core is formed, which has adhesive for insulating the magnetically conductive material and has sufficient strength for further processing. For each width of the magnetically conductive material, with the exception of the widest material, there must be two supply rolls, including all devices, and two take-up devices, including all devices, corresponding to the number of stages of the toroidal core. In the steady state, all stock roll units and all take-up units are in operation simultaneously.
Der Vorteil der Ringkerntechnologie besteht darin, dass man damit Ringkernverteilungstransformatoren bis in den höchsten Leistungsbereich realisieren kann, welche extrem verlustarm sind und nur noch ca. 50% der Betriebkosten von konventionellen Verteilungstransformatoren in Gießharztechnik aufweisen. Dadurch refinanziert sich der Ringkernverteilungstransformator in wenigen Jahren und zusätzlich kann ein bedeutender Teil an Primärenergie, zur Schonung von Ressourcen und der Umwelt, eingespart werden.The advantage of the toroidal core technology is that it allows toroidal distribution transformers to be realized in the highest power range, which are extremely low-loss and only about 50% of the operating costs of conventional distribution transformers in casting resin technology. As a result, the toroidal distribution transformer refinances in a few years and, in addition, a significant amount of primary energy, for the conservation of resources and the environment, can be saved.
Mit der oben beschriebenen Ringkernwickelvorrichtung wird eine rationelle Produktion von Ringkerntransformatoren dadurch erreicht, dass zum Beispiel bei elf Stufen, elf Ringkerntransformatorkerne gleichzeitig gewickelt werden können.With the toroidal core winding apparatus described above, rational production of toroidal transformers is achieved by, for example, eleven stages, eleven toroidal transformer cores can be wound simultaneously.
Die Aufgabe wird auch gelöst durch einen Transformator, insbesondere eine spiralförmige Unterspannungswicklung hohen Querschnitts und deren Herstellung, einen mehrstufigen geschlossenen Ringkerntransformatorkern hoher Stabilität, aus magnetisch leitendem und gegenseitig isoliertem Material, zur Unterspannungswicklung hin elektrisch isoliert, sowie dessen Herstellungsverfahren, wobei bevorzugt ein Trägergestell mit mindestens 3 Vorratsrollenvorrichtungen mit jeweils einer Bremsvorrichtung, mit mindestens 2 verschiedenen Breiten von magnetisch leitendem Material, mindestens drei Klebesprühvorrichtungen, sowie mindestens drei Aufwickelvorrichtungen mit einem Antriebssystem, mindestens drei Führungsvorrichtungen, einer Führungsschiene, sowie einer Abschneidevorrichtung vorgesehen ist.The object is also achieved by a transformer, in particular a spiral undervoltage winding high cross-section and their manufacture, a multi-stage closed toroidal transformer high stability, of magnetically conductive and mutually insulated material, electrically insulated for undervoltage winding, and its manufacturing process, preferably a support frame with at least 3 supply roll devices, each with a braking device, with at least 2 different widths of magnetically conductive material, at least three adhesive spraying devices, and at least three winding devices with a drive system, at least three guide devices, a guide rail, and a cutting device is provided.

Die Führungsschienen 105a, 105b bestehen jeweils aus isolierendem Material, so dass die Ringkerne 102 beziehungsweise die Phasenwicklungen auf den Spulenkörper 103 der Ringkerne 102 seitlich nach außen hin isoliert sind.The
Die Haltevorrichtung 104 weist unterseitig ein Bodenteil 107 auf, das ebenfalls aus isolierendem Material besteht. An dem Bodenteil 107 sind isolierende Auflageelemente 108 für den unteren Ringkern 102 vorgesehen. Dabei können mehrere voneinander beabstandete Auflageelemente 108 vorgesehen sein, oder es ist ein durchgehender Ring als Auflageelement 108 vorgesehen. Zwischen den einzelnen Ringkernen 102 sind jeweils Distanzstücke 109 vorgesehen, mit denen die Ringkerne 102 beziehungsweise die den Ringkernen 102 jeweils zugeordneten Spulenkörper 103 in ihrer Lage zueinander fixiert werden. Oberhalb des oberen Ringkernes 102 sind wiederum isolierende Auflageelemente 108 vorgesehen, auf denen ein Deckelteil 110 aufliegt und die Ringkerne 102 auch oberseitig nach außen hin isoliert.The

Insbesondere im Bereich der Distanzstücke 109, das heißt dort, wo benachbarte Ringkerne den geringsten Abstand zueinander haben, ist dadurch an zwei gegenüberliegenden Bereichen zweier Ringkerne 102 beziehungsweise Spulenkörper 103 praktisch kein Potentialunterschied vorhanden. Spannungsüberschläge zwischen benachbarten Ringkernen 102 sind so auch bei dicht aneinander angeordneten Ringkernen 102 nicht möglich. Der Mehrphasentransformator 101 kann dadurch kompakt und mit reduziertem Platzbedarf aufgebaut werden.
