Description

Kühleinrichtung für die Leiter elektrischer Apparate und Maschinen innerhalb der Wicklungsnut, bei der die Leiter nach allen Seiten derart abgestützt sind, daß die Abstützungen quer zur Längsachse der Leiter verlaufende Unterbrechungen aufweisen, durch die Kühlluft geführt wird Vorliegende Erfindung betrifft die Kühlung von Leitern in den Wicklungsnuten elektrischer Apparate und Maschinen, bei der die Kühlluft innerhalb der Nuten zirkuliert.Cooling device for the conductors of electrical apparatus and machines within the winding groove, in which the conductor is supported on all sides in this way are that the supports are transverse to the longitudinal axis of the ladder interruptions have through which cooling air is passed. The present invention relates to cooling of conductors in the winding grooves of electrical apparatus and machines in which the Cooling air circulates within the grooves.

Das Neue besteht darin, daß die Oberfläche der Leiter nach allen Seiten abgestützt ist, wobei die Leiter in jeder senkrecht zu ihrer Längsachse gelegten Ebene auch an den Unterbrechungsstellen abgestützt sind, obwohl die Abstützungen quer zur Längsachse der Leiter verlaufende Unterbrechungen aufweisen. Dabei ist wenigstens ein Teil der Abstützungen derart angeordnet und geformt, daß die Kühlluft zwecks Vergrößerung der Berührungsflächen mit den Leitern gezwungen wird, bei der Bespülung der Leiter einer zickzackförmigen. Bahn zu folgen.The novelty is that the surface of the ladder is on all sides is supported, the ladder in each laid perpendicular to its longitudinal axis Level are also supported at the interruption points, although the supports have interruptions running transversely to the longitudinal axis of the conductors. It is at least some of the supports are arranged and shaped in such a way that the cooling air for the purpose of enlarging the contact areas with the conductors is forced in the Flushing the head of a zigzag. Track to follow.

In beiliegender Zeichnung sind drei beispielsweise Ausführungsrformen der Wicklungsnut veranschaulicht, und zwar sind Abb. I ein Längsschnitt einer ersten Ausführungsform, Abb. 2 ein Schnitt nach Linie II-II von Abb. I in größerem Maßstabe, Abb. 3 und 4 Längsschnitte durch die zwei anderen Ausführungsformen.In the accompanying drawing there are three exemplary embodiments of the winding groove illustrated, namely Fig. I is a longitudinal section of a first Embodiment, Fig. 2 a section along line II-II of Fig. I on a larger scale, Fig. 3 and 4 longitudinal sections through the two other embodiments.

Nach Abb. I bis 4 besitzt die Wicklungsnut a einen rechteckigen Querschnitt und enthält den Leiter b, der ebenfalls einen rechteckigen Querschnitt aufweist, dessen Fläche aber ziemlich kleiner ist als diejenige des Nutenquerschnittes; es bleibt somit zwischen dem Leiter b und der Nutenwandung c ein freier Raum, in welchem Distanzstücke d, e vorgesehen sind. Dieselben haben einen U-förmigen Querschnitt, sitzen rittlings auf dem Leiter b, haben Flansche von dreieckförmiger Gestalt und sind gegeneinander so versetzt angeordnet, daß auf beiden Seiten des Leiters b zickzackförmige Kanäle f, g zur Führung der Kühlluft im Innern der Nut entstehen. Diese letztere ist wie gewöhnlich nach außen durch einen Keil h angeschlossen.According to Fig. I to 4, the winding groove a has a rectangular cross-section and contains the conductor b, which also has a rectangular cross-section, but the area of which is quite smaller than that of the groove cross-section; it thus remains a free space between the conductor b and the groove wall c, in which Spacers d, e are provided. They have a U-shaped cross-section, sit astride the ladder b, have flanges of triangular shape and are offset from each other so that on both sides of the conductor b zigzag Channels f, g for guiding the cooling air are created inside the groove. This latter is connected to the outside by a wedge h as usual.

Auf diese Weise werden die Kühlluftkanäle möglichst nahe an den nackten oder isolierten Leiter verlegt, dessen Wärme abgeführt werden soll.In this way, the cooling air ducts are as close as possible to the bare ones or insulated conductor laid whose heat is to be dissipated.

Die Distanzstücke, welche über die ganze Nutenhöhe den Leiter b von der Nutenwandung c entfernt halten, können aus Isolationsmaterial, aus mit Isolationsmaterial ausgeklebtem Metall oder auch nur aus Metall bei isoliertem Leiter b bestehen.The spacers, which over the entire groove height, the conductor b of keep the groove wall c away, can be made of insulation material, with insulation material glued metal or just made of metal with insulated conductor b.

Die Luftführung kann dabei in an sich bekannter Weise erfolgen. In der ersten Ausführungsform (Abb. I) tritt z. B. die Kühlluft durch ein Nutenende i hinein und durch das andere j hinaus; in der zweiten (Abb.3) tritt sie gleichzeitig durch beide Nutenenden i, j ein und durch im mittleren Teil, des Keiles h vorgesehene Abzuglöcher k hinaus. Sie kann auch durch entsprechende Kanäle l (Abb. 4) in die Nutenmitte eingeführt werden und durch die beiden Nutenenden i, j hinausströmen.The air flow can take place in a manner known per se. In the first embodiment (Fig. I) z. B. the cooling air in through one end of the groove i and out through the other j; in the second (Fig.3) it enters simultaneously through both groove ends i, j and out through drainage holes k provided in the middle part of the wedge h. It can also be introduced into the middle of the groove through corresponding channels l (Fig. 4) and flow out through the two groove ends i, j.

Die Gestalt und die Anordnung der Distanzstücke und der Verlauf der Kanäle können von den dargestellten abweichen.The shape and arrangement of the spacers and the course of the Channels can differ from those shown.

Der Einfachheit halber wurde der Leiter als ein massiver von rechteckigem Querschnitt dargestellt; er kann natürlich jede andere Gestalt und Beschaffenheit besitzen.For the sake of simplicity, the ladder was considered a solid of rectangular Cross section shown; it can, of course, have any other shape and quality own.
