Description
Verfahren zur Herstellung von Ringspulen, wie Transformatoren, Belastungsspulen u. dgl. Bei den in der Schwachstromtechnik verwendeten Belastungsspulen oder Ringübertragern ist mit Rücksicht auf das kapazitive Übersprechen eine Kleinhaltung der beim Übersprechen mitwirkenden Kapazitäten notwendig.Process for the production of toroidal coils, such as transformers, load coils and the like in the case of the load coils or ring transformers used in low-voltage technology With regard to the capacitive crosstalk, the crosstalk is kept to a minimum participating capacities are necessary.
Die üblichen Belastungsspulen und Ringübertrager werden entweder mit Faserstoffen ohne nachherige Imprägnierung isoliert oder die gewickelten Ringe werden noch imprägniert. Die nicht imprägnierten Wicklungen enthalten immer Feuchtigkeit im Faserstoff, so daß sie hohen Isolationsbedingungen nicht genügen. Das Imprägnieren von Wicklungen, z. B. bei Ringübertragern, hat den Nachteil, daß die Kapazitäten der Wicklungen erhöht werden. Ferner besteht immer die Möglichkeit, daß die Wicklungen von der Imprägniermasse ungleichmäßig durchsetzt werden, insbesondere dann, wenn die Imprägniermasse durch Bandagen hindurchtreten muß, so daß sich die einzelnen Kapazitäten innerhalb der Wicklungen verschieden stark ändern.The usual loading coils and ring transformers are either with Fibers are isolated without subsequent impregnation or the wrapped rings still impregnated. The unimpregnated windings always contain moisture in the fiber, so that they do not meet high insulation conditions. The impregnation of windings, e.g. B. in ring transformers, has the disadvantage that the capacities the windings are increased. Furthermore, there is always the possibility that the windings are penetrated unevenly by the impregnation compound, especially when the impregnation must pass through bandages so that the individual Change capacities within the windings to different degrees.
Die vorliegende Erfindung bezieht sich nun auf ein Verfahren zur Herstellung von Ringspulen, wie Transformatoren, Belastungsspulen u. dgl., und bezweckt, die angeführten Nachteile zu vermeiden. Gemäß der Erfindung wird dies dadurch erreicht, daß die gewickelten und außen bandagierten Spulen unter Wärme vorgetrocknet, sodann unter Vakuum und Wärme getrocknet und anschließend in Vergußmasse derart kurzzeitig getaucht werden, daß die Vergußmasse eine nur dünne Schicht um die Spulen bildet. Das Umhüllen der Wicklungen mit Vergußrnasse, das z. B. durch Tauchen oder durch Vergießen geschehen kann, erfolgt entweder sofort nach dem Trocknen unter Vakuum noch innerhalb des Vakuumkessels oder anschließend an das Trocknen außerhalb des Kessels. Im letzteren Falle werden die gewickelten und außen bandagierten Ringe in die Übertragerkappen eingelegt und bei offener Kappe unter Wärme vorgetrocknet, sodann unter Vakuum und Wärme getrocknet und anschließend mit Vergußmasse vergossen.The present invention now relates to a method of manufacture of toroidal coils, such as transformers, load coils and the like to avoid the disadvantages mentioned. According to the invention this is achieved by that the wound and externally bandaged coils are pre-dried under heat, then dried under vacuum and heat and then briefly in potting compound are dipped so that the potting compound forms only a thin layer around the coils. The wrapping of the windings with Vergußrnasse, the z. B. by diving or by Potting can be done either immediately after drying under vacuum still inside the vacuum vessel or after the drying outside of the Boiler. In the latter case, the wrapped and externally bandaged rings are used placed in the transfer caps and pre-dried under heat with the cap open, then dried under vacuum and heat and then potted with potting compound.
