Description
Bekanntlich werden die Wickel von Kondensatoren durch Zugklammern aus Blech oder Zugbänder aus Stahl zusammengepreßt. Während der Aufwand für die verhältnismäßig kräftigeren Zugklammern sehr groß ist, ergeben die genannten Stahlbänder unter Umständen elektrische Schwierigkeiten, mit Rücksicht auf durch deren Kanten hervorgerufene Feldverzerrungen. Außerdem tritt bei Verwendung der bekannten Einrichtungen zum Zusammenpressen der Wickel eine ungleichmäßige Verteilung des mechanischen Druckes über die Länge der Wickel ein.It is well known that the winding of capacitors is made by tension clips made of sheet metal or steel ties. While the effort for the relatively stronger tension clamps is very large, result in the steel bands mentioned possibly electrical difficulties, with due regard for their edges caused field distortions. It also occurs when using the known facilities an uneven distribution of mechanical pressure to compress the winding along the length of the wrap.
Alle diese Nachteile werden gemäß der Erfindung dadurch vermieden, daß Wickelpakete durch ganz oder teilweise sie umfassende Folien unter Druck gehalten werden. Damit wird für das Zusammenpressen der Wickel äußerst wenig Raum beansprucht. Da nunmehr scharfe Kanten gegenüber den Wickelfolien fehlen, ergibt sich eine günstige Feldverteilung. Die Folien gemäß der Erfindung nehmen die durch das Zusammendrücken der Wickel auftretenden Zugkräfte gleichmäßig auf, so daß die Druckplatten verhältnismäßig schwach gemacht werden können. Die angegebenen Folien können aus Isolierstoff, z. B, Papier bzw. Künstsitoff, oder Metall hergestellt werden. Sie können aus einer oder mehr Lagen bestehen. Werden Metallfolien verwendet, dann können diese nach dem Herumwickeln um die Kondensatorwickel dadurch festgehalten werden, daß insbesondere an deren Enden übereinanderliegende Lagen durch Punkt-oder Nahtschweißungen miteinander verbunden werden. Bei Verwendung von Metallfolien ergibt sich außerdem der Vorteil, daß eine verhältnismäßig unnachgiebige Zusammenpressung der Wickel gewährleistet ist. Ferner ist der Wärmewiderstand der Metallfolien sehr gering, so daß, beispielsweise bei Hochfrequenzkondensatoren, die Wärme von den eingelegten oder herumgewickelten Folien der Kondensatorwickel leicht zur Wand des Kondensatorgehäuses geleitet werden kann.All these disadvantages are avoided according to the invention by that winding packages are kept under pressure by completely or partially covering foils will. This means that extremely little space is required for compressing the winding. Since there are now no sharp edges compared to the wrapping foils, the result is a favorable one Field distribution. The films according to the invention take by compression the winding occurring tensile forces evenly, so that the pressure plates relatively can be made weak. The specified films can be made of insulating material, for. B, paper or plastic, or metal can be produced. You can choose from a or more layers. If metal foils are used, these can be used according to the wrapping around the capacitor winding are held in that in particular at their ends superimposed layers by spot or seam welds to one another get connected. The use of metal foils also has the advantage that ensures a relatively unyielding compression of the winding is. Furthermore, the thermal resistance of the metal foils is very low, so that, for example in the case of high frequency capacitors, the heat from the inserted or wrapped around Foils of the capacitor winding are easily guided to the wall of the capacitor housing can.
In Fig, i der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Kondensatorwickel i sind zwischen Druckplatten :2 angeordnet. Das so gebildete Wickelpaket wird gemäß der Erfindung durch. eine darumgewickelte, z. B. aus Aluminium bestehende Metallfolie 3 zusammengepreßt. Diese Metallfolie besitzt vorteilhaft eine Stärke von etwa o,i mm. Der erforderliche Preßdruck beim Herumlegen der Folie wird beispielsweise durch Preßstempel 4 erzeugt. Die Folie besitzt an den Enden Schlitze 5, die ihr Herumlegen während des Zusammenpressens gestatten. Bei der hier angegebenen Verwendung einer Metallfolie werden deren Enden 6 durch eine Punktschweißung 7 oder eine Nahtschweißung miteinander fest verbunden. Wird hingegen Papier für die Folie 3 verwendet, dann wird dieses zweckmäßig geheftet oder geklebt. Werden Metallfolien verwendet, dann reichen diese zweckmäßig bis an die Wickelenden und werden etwa an das mittlere Potential des umfaßten Wickelpaketes gelegt. Auf diese Weise gelingt es, das Potentialgefälle von den Ecken und Kanten des Wickelpaketes zum Kondensatorgehäuse zu unterteilen bzw. genau festzulegen. Damit wird insbesondere eine Gasung des Imprägniermittels verhindert. Bei einem derartigen Anschluß der Folien können deren Enden an den Wickelstirnseiten 8 auch über diese gezogen bzw. abgebogen werden. Damit wird eine besonders wirksame Abschirmung der Ecken .und Kanten des Wickelpaketes erzielt.In Fig, i of the drawing is an embodiment of the invention shown. The capacitor windings i are arranged between pressure plates: 2. That thus formed winding package is according to the invention by. a wrapped around it, e.g. B. made of aluminum metal foil 3 pressed together. This metal foil possesses advantageously a thickness of about 0.1 mm. The required pressure when laying around the film is produced, for example, by a press die 4. The slide has on slots 5 at the ends allowing them to be laid around during compression. When a metal foil is used here, the ends 6 thereof are penetrated a spot weld 7 or a seam weld firmly connected to one another. Will on the other hand, paper is used for the film 3, then this is appropriately stapled or glued. If metal foils are used, then these are expediently up to the winding ends and are approximately at the mean potential of the winding package included placed. In this way it is possible to reduce the potential gradient from the corners and edges to subdivide or precisely define the winding package to the capacitor housing. This in particular prevents gassing of the impregnating agent. At a Such a connection of the foils can also have their ends on the end faces 8 of the winding be pulled or bent over this. This is a particularly effective shield the corners and edges of the winding package.
Die Fig.2 und 3 zeigen weitere Beispiele der Erfindung. Hierbei umfassen die beispielsweise wieder aus Aluminium bestehenden Folien 9 das Wickelpaket nur teilweise. Gemäß Fig. 2 werden die Enden dieser Folie mit der hier aus Metall, z. B. Aluminium oder Eisen, hergestellten oberen Druckplatte io z. B. durch Schweißung verbunden. Bestehen die Folie 9 und die Druckplatte io aus Metall, dann wird zweckmäßig noch Isolation ii vorgesehen. Bei der in Fig. 3 dargestellten Ausführung wird .die Verbindung zwischen den Folienenden durch eine Zwischenfolie 12 hergestellt, die wieder aus Metall, z. B. Aluminium, bestehen kann.Figures 2 and 3 show further examples of the invention. Include here the foils 9, which are again made of aluminum, for example, only form the winding package partially. According to Fig. 2, the ends of this film with the here made of metal, for. B. aluminum or iron, manufactured upper pressure plate io z. B. by welding tied together. If the foil 9 and the pressure plate io are made of metal, then it is expedient still isolation ii provided. In the embodiment shown in Fig. 3 .die Connection between the ends of the film produced by an intermediate film 12, which again made of metal, e.g. B. aluminum, may exist.
