Description

Stromwandler in Kaskadenbauweise mit geteiltem Isolator und mehreren Kernen unterschiedlicher Genauigkeit Das Hauptpatent hat einen Stromwandler in Kaskadenbauweise mit geteiltem Isolator und mehreren Kernen unterschiedlicher Genauigkeit zum Gegenstand, bei dem die Zuleitungen zu den Kernen auf der erdseitigen Stufe der Kaskade in einer gemeinsamen spannungsgesteuerten Durchführung verlegt und erst nach ihrem Austritt aus dem spannungsgesteuerten Bereich der Durchführung derart getrennt weitergeführt sind, daß zur Vermeidung gegenseitiger Kernbeeinflussung ein dementsprechender Abstand zwischen den Kernen eingehalten ist.Cascade current transformers with split insulator and several Cores of different accuracy The main patent has a current transformer in cascade design with a split insulator and several cores of different accuracy to the object, in which the supply lines to the cores on the earth-side level of the cascade in one joint voltage-controlled implementation relocated and only after their exit continued so separately from the voltage-controlled area of the implementation are that to avoid mutual core influence a corresponding distance is observed between the cores.

Gemäß der Zusatzerfindung ist mindestens einer der in der erdseitigen Stufe der Kaskade vorhandenen Kerne, die mit den zugehörigen Wicklungen übereinander angeordnet sind, in zwei gleiche Kernteile aufgeteilt, die unter Anwendung einer für mehrschenklige Transformatoren an sich bekannten Schrägstellung über den Umfang ihrer Primärwicklung oder die Ausladung des anderen Kernes in dieser Kaskadenstufe nicht hinausragen.According to the additional invention, at least one is in the earth-side Stage of the cascade existing cores, which are stacked with the associated windings are arranged, divided into two equal core parts using a for multi-leg transformers known inclination over the circumference their primary winding or the projection of the other core in this cascade stage do not protrude.

Durch diese Schrägstellung, die bei bekannten Transformatoren mit mehrschenkligem Eisenkörper zur Erzielung einer hinsichtlich ihrer Grundfläche platzsparenden Kernbauform dient, wird bei der Erfindung der Vorteil erzielt, daß der Durchmesser des die erdseitige Stufe umgebenden Isolators z. B. nur durch den Platzbedarf der Primärwicklung bestimmt ist. Diese Anordnung gestattet es, auch bei versetzter Anordnung der Kerne verschiedener Genauigkeit einen raumsparenden Aufbau zu erreichen, da z. B. bei Verwendung eines Schenkelkernes als unterer Kern die Teilkerne des darüber angeordneten Systems innerhalb des Isolators untergebracht werden können, dessen Durchmesser durch die Ausladung des Schenkelkernes und seiner Primärwicklung gegeben ist.Due to this inclination, which in known transformers with multi-limbed iron body to achieve a space-saving in terms of its footprint Core design serves, the advantage is achieved in the invention that the diameter of the isolator surrounding the earth-side stage z. B. only by the space required by the Primary winding is determined. This arrangement allows it, even with a staggered arrangement to achieve a space-saving structure of the cores of different accuracy, since z. B. when using a leg core as the lower core, the partial cores of the above arranged system can be housed within the isolator, its Diameter given by the projection of the leg core and its primary winding is.

In der F i g. 1 ist zur Erläuterung der Erfindung als Ausführungsbeispiel schematisch ein Stromwandler in zweistufiger Bauweise dargestellt, der in der erdseitigen Stufe zwei entkoppelte Meßsysteme aufweist. In der hochspannungsseitigen Stufe sind der Primärleiter 1 und die beiden Kerne 2 mit ihren Sekundärwicklungen angeordnet, die gemeinsam mit der für die entsprechende Prüfspannung benötigten Isolation 3 versehen sind. Als Abschluß trägt die Isolation 3 den leitenden Belag 4.In FIG. 1 is to explain the invention as an exemplary embodiment schematically shows a current transformer in two-stage design, the one in the earth-side Stage has two decoupled measuring systems. Are in the high-voltage side stage the primary conductor 1 and the two cores 2 with their secondary windings arranged, the insulation required for the corresponding test voltage 3 are provided. As a conclusion, the insulation 3 carries the conductive coating 4.

In der erdseitigen Stufe sind zwei entkoppelte Meßsysteme mit den um 90° verdreht angeordneten Primärwicklungen 5 und 6 sowie den zugehörigen Eisenkernen 7a/7b und 8, die die nicht gezeigten Sekundärwicklungen tragen, untergebracht. Bei dem gezeigten Ausführungsbeispiel ist nur der obere Kern in zwei gleiche Kernteile 7 a und 7 b aufgeteilt, die unter einem so großen Winkel zur senkrechten Achse angeordnet sind, daß sie in radialer Richtung nicht mehr ausladen als die Primärwicklung 5 mit der Isolation 9 bzw. der Kern 8 sowie die Primärwicklung 6 mit der Isolation 10. Dies ist aus der eine andere Ansicht wiedergebenden F i g. 2 ersichtlich.Two decoupled measuring systems with the primary windings 5 and 6 rotated by 90 ° and the associated iron cores 7a / 7b and 8, which carry the secondary windings (not shown), are accommodated in the earth-side stage. In the embodiment shown, only the upper core is divided into two identical core parts 7 a and 7 b , which are arranged at such a large angle to the vertical axis that they do not extend more radially than the primary winding 5 with the insulation 9 or the core 8 and the primary winding 6 with the insulation 10. This is shown in FIG. 2 can be seen.

Man kann auch noch den Kern 8 Schrägstellen und damit die Bauhöhe weiter herabsetzen.You can also tilt the core 8 and thus further reduce the overall height.
