Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den im Hauptpatent beschriebenen Transformatoren ist es mitunter wünschenswert, daß die verschiedenen, einstellbaren Nullpunkte von der Außenseite des Transformatorkastens aus zugänglich sind. Dies kann gemäß der Erfindung dadurch erreicht werden, daß für diese Nullpunkte ein besonderer beweglicher oder fester Durchführungsisolator vorgesehen wird.With the transformers described in the main patent, it is sometimes desirable that the various, adjustable zero points from the outside of the transformer box are accessible from. According to the invention, this can be achieved by that for these zero points a special movable or fixed bushing insulator is provided.

Die Figuren zeigen Ausführungsbeispiele. Die Bezeichnungen stimmen mit denen des Hauptpatentes überein. Bei Fig. 1 tritt an Stelle des Kurzschlußstöpsels der bewegliche, von außen einführbare Durchführungsisolator I, der durch ein am unteren Ende der Durchführung 0 vorgesehenes Gewinde zwischen die ebenfalls mit Gewinde versehenen Anschlüsse X1 und xz bzw. y1 und y3 bzw. Z1 und ^3 so weit eingeschraubt wird, bis auch der Anschluß X2 bzw. y2 bzw. Z2 berührt wird.The figures show exemplary embodiments. The designations agree with those of the main patent. In Fig. 1, instead of the short-circuit plug, the movable bushing insulator I, which can be inserted from the outside, is inserted between the also threaded connections X 1 and x z or y 1 and y 3 or through a thread provided at the lower end of the bushing 0. Z 1 and ^ 3 are screwed in until the connection X 2 or y 2 or Z 2 is touched.

Bei der Ausführung nach Fig. 2 sind die sämtlichen Anschlüsse X1 x2 χΆ bzw. J1 y2 y3 bzw. Z1 z.z Z3 mit Gewinde versehen. Durch Einschrauben des Kurzschlußstöpsels kann die Verbindung mit den Nullpunktanschlüssen 0' bzw. 0" bzw. 0'" hergestellt werden. Die Nullpunktanschlüsse sind mittels der gemeinsamen Leitung d, die durch einen festen Durchführungsisolator führt, mit dem äußeren Nullpunkt 0 verbunden.In the embodiment according to FIG. 2, all of the connections X 1 x 2 χ Ά or J 1 y 2 y 3 or Z 1 z. z Z 3 provided with thread. The connection to the zero point connections 0 ' or 0 " or 0'" can be established by screwing in the short-circuit plug. The zero point connections are connected to the external zero point 0 by means of the common line d, which runs through a fixed bushing insulator.
