Die Erfindung betrifft eine Stützvorrichtung eines Aktivteils eines Stromwandlers und einen Stromwandler.The invention relates to a support device of an active part of a current transformer and a current transformer.

Aktivteile von Stromwandlern werden in der Regel in Abhängigkeit von ihrem Gewicht von zwei oder vier Isolierstützen abgestützt, die das Gewicht und die mechanischen Lasten des Aktivteils übernehmen. Die Einbaulage ist dabei je nach Modell entweder hängend oder stehend.Active parts of current transformers are usually supported, depending on their weight of two or four insulating supports, which take over the weight and the mechanical loads of the active part. Depending on the model, the installation position is either suspended or upright.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Stützvorrichtung eines Aktivteils eines Stromwandlers und einen verbesserten Stromwandler anzugeben.The invention has for its object to provide an improved support device of an active part of a current transformer and an improved current transformer.

Eine erfindungsgemäße Stützvorrichtung eines Aktivteils eines Stromwandlers umfasst mehrere Isolierstützbeine aus einem elektrisch isolierenden Material, die dazu ausgebildet sind, den Aktivteil zu tragen und sich auf einem Gehäuseboden eines Gehäuses des Stromwandlers abzustützen, wobei eine Längsachse jedes Isolierstützbeins einen nicht verschwindenden Stützwinkel mit der Schwerkraftrichtung bildet.A support device according to the invention of an active part of a current transformer comprises a plurality of insulating support legs made of an electrically insulating material, which are adapted to support the active part and to be supported on a housing bottom of a housing of the current transformer, wherein a longitudinal axis of each Isolierstützbeins forms a non-vanishing support angle with the direction of gravity.

Die Stützwinkel werden dabei vorzugsweise derart gewählt, dass die Isolierstützbeine bei einem Transport des Stromwandlers horizontale und/oder seitliche Beschleunigungen des Stromwandlers auffangen. Dadurch wird der Stromwandler vorteilhaft vor Transportschäden geschützt, die durch derartige Beschleunigungen verursacht werden können.The support brackets are preferably chosen such that the Isolierstützbeine capture in a transport of the current transformer horizontal and / or lateral accelerations of the current transformer. As a result, the current transformer is advantageous protected against transport damage that can be caused by such accelerations.

Eine Ausgestaltung der Erfindung sieht vor, dass die gehäusebodenseitigen Enden je zweier Isolierstützbeine einen größeren Abstand voneinander aufweisen als die aktivteilseitigen Enden dieser Isolierstützbeine.An embodiment of the invention provides that the housing bottom side ends of each two Isolierstützbeine have a greater distance from each other than the active part-side ends of Isolierstützbeine.

Dadurch spreizen sich die Isolierstützbeine von dem Aktivteil zu dem Gehäuseboden, so dass sie besonders vorteilhaft horizontale und/oder seitliche Beschleunigungen des Stromwandlers aufnehmen können.As a result, the insulating support legs spread from the active part to the housing bottom, so that they can accommodate particularly advantageous horizontal and / or lateral accelerations of the current transformer.

Eine weitere Ausgestaltung der Erfindung sieht genau vier Isolierstützbeine vor.Another embodiment of the invention provides exactly four insulating support legs.

Dies ermöglicht eine besonders stabile Abstützung des Aktivteils.This allows a particularly stable support of the active part.

Ein erfindungsgemäßer Stromwandler umfasst ein Gehäuse, einen in dem Gehäuse angeordneten Aktivteil und eine erfindungsgemäße Stützvorrichtung zur Abstützung des Aktivteils mit den oben bereits genannten Vorteilen.A current transformer according to the invention comprises a housing, an active part arranged in the housing and a supporting device according to the invention for supporting the active part with the advantages already mentioned above.

Vorzugsweise ist am Gehäuseboden für jedes Isolierstützbein eine Halterung zur gehäusebodenseitigen Fixierung des Isolierstützbeins angeordnet. Dadurch werden die Isolierstützbeine vorteilhaft in dem Gehäuse, insbesondere zu einem Transport des Stromwandlers, befestigt.Preferably, a holder for housing-side fixing of the Isolierstützbeins is arranged on the housing bottom for each Isolierstützbein. As a result, the insulating support legs are advantageously fastened in the housing, in particular for transporting the current transformer.

Ferner weist das Gehäuse vorzugsweise ein Gehäuseunterteil mit dem Gehäuseboden und ein Gehäuseoberteil auf, wobei das Gehäuseunterteil und das Gehäuseoberteil lösbar miteinander verbindbar sind.Furthermore, the housing preferably has a lower housing part with the housing bottom and an upper housing part, wherein the lower housing part and the upper housing part are detachably connectable to each other.

Diese Gestaltung des Gehäuses erleichtert vorteilhaft die Montage des Aktivteils und der Stützvorrichtung in dem Gehäuse.This design of the housing advantageously facilitates the assembly of the active part and the support device in the housing.
