Description
Als Hochspannungsdurchführung dienender Stromwandler Bei den bisher bekannt gewordenen Durchführungsstromwandlern ist es notwendig, besonders geformte Porzellankörper zu verwenden, deren Herstellung schwierig ist, da man in den Durchführungsporzellankörper einen zweiten Porzellankörper einsetzen muß. Um die Anordnung solcher Durchführungsstromwandler zu vereinfachen und um diese auch bei geringer Stromstärke verwenden zu können, wird gemäß der Erfindung eine aus einem Stück bestehende Durchführung verwendet, in deren Innern ein die Primärwicklung tragender Eisenkern eingesetzt ist. Die Sekundärwicklung ist auf einem den Isolierkörper umgebenden Eisenring angebracht, der so ausgebildet ist, daß nur ein Teil dieses Ringes mit der Sekundärwicklung versehen ist. Der übrige Teil ist bis zur Wandung des Isolierrohres herangezogen und dient als Polschuh. Wird auch der in die Durchführung eingesetzte Eisenkern mit Verbreiterungen an seinen Enden versehen, und liegen diese den Polschuhen des äußeren Eisenringes gegenüber, so wird ein direkter Kraftlinienweg erzielt und eine ungünstige Streuung vermieden.Current transformer serving as high-voltage bushing known bushing current transformers, it is necessary to use specially shaped To use porcelain bodies, the manufacture of which is difficult, because you are in the lead-through porcelain body must use a second porcelain body. To the arrangement of such bushing current transformers to simplify and to be able to use them even with low amperage, a one-piece implementation is used according to the invention, inside of which an iron core carrying the primary winding is inserted. The secondary winding is attached to an iron ring surrounding the insulating body, which is designed in this way is that only part of this ring is provided with the secondary winding. The rest Part is pulled up to the wall of the insulating tube and serves as a pole piece. The iron core used in the implementation is also used with widenings on its Ends, and these are opposite the pole pieces of the outer iron ring, in this way a direct path of the lines of force is achieved and an unfavorable scatter is avoided.
Die Abbildungen zeigen eine der möglichen Ausführungsformen dieser Neuerung. a ist die Durchführung, in die der Eisenkern b mit der Primärwicklung c eingesetzt ist. rd ist der äußere Eisenring, der seitlich die sekundäre Wicklung c trägt, während der Teil f als Polschuh ausgebildet ist, Der Eisenkern b besitzt seitlich an seiner Außenseite Verbreiterungen g, die als Polschuhe mit f korrespondieren und so die Streuung verringern.The figures show one of the possible embodiments of this Innovation. a is the implementation in which the iron core b with the primary winding c is inserted. rd is the outer iron ring, which is the secondary winding on the side c carries, while the part f is designed as a pole piece, the iron core b has laterally on its outside widenings g, which correspond as pole shoes with f and thus reduce the spread.
