Description
Elektrischer Wickelkondensator, an dessen leitende Beläge halbleitende Schichten angeschlossen sind, welche zusammen mit den leitenden Schichten vor dem Zusammenbau des Kondensators auf eine gemeinsame Unterlage aufgebracht werden Zur Verminderung der maximalen Feldstärke an den Rändern von Kondensatoreinlagen und damit zur Herabsetzung der Überschlags- und Durchschlagsbeanspruchung am Kondensator ist es bekannt, an die Belagränder Schichten aus einem halbleitenden Material anzuschließen. Diese Schichten können dabei von dem einen Belagrand bis zum nächsten verlaufen und so eine halbleitende Verbindung zwischen zwei Kondensatorbelägen herstellen. Es kann aber auch noch eine Isolationsstrecke dazwischen geschaltet sein. Die vorliegende Erfindung betrifft nun einen elektrischen Wickelkondensator, an dessen leitende Beläge halbleitende Schichten angeschlossen sind, welche zusammen mit den leitenden Schichten vor dem Zusammenbau des Kondensators in an sich bekannter Weise auf eine gemeinsame Unterlage aufgebracht werden.Electrical wound capacitor, on whose conductive surfaces semiconducting Layers are connected, which together with the conductive layers before Assembly of the capacitor can be applied to a common base Reduction of the maximum field strength at the edges of capacitor inserts and thus reducing the flashover and breakdown stress on the capacitor it is known to connect layers of a semiconducting material to the pavement edges. These layers can run from one edge of the pavement to the next and thus create a semiconducting connection between two capacitor plates. However, an isolation path can also be connected in between. The present The invention now relates to an electrical wound capacitor, on the conductive Coverings semiconducting layers are connected, which together with the conductive Layers prior to assembling the capacitor in a known manner on a common base can be applied.
Erfindungsgemäß stellt die z. B. aus einem Papierband bestehende gemeinsame isolierende Unterlage einen besonderen Träger dar, welcher nach dem Aufbringen der leitenden, und halbleitenden Schichten zwischen die eigentlichen Isolationsschichten eingewickelt wird. An sich ist es bereits bekannt, bei als Durchführungsisolatoren ausgebildeten Wickelkondensatoren vor dem Zusammenbau des Kondensators den leitenden Belag und die halbleitenden Schichten auf eine gemeinsame Unterlage aufzubringen. Diese gemeinsame Unterlage bildet nachher die Isolierschicht zwischen zwei leitenden Belägen. Demgegenüber sind bei der Anordnung nach der Erfindung zwischen den einzelnen leitenden Belägen, noch besondere Isolierschichten eingewickelt. Dies hat folgenden Vorteil: Wenn der leitende Belag und die halbleitenden Schichten vorher auf die die Isolierung bildende Papierbahn aufgebracht werden und dann diese Papierbahn aufgewickelt wird, so darf die Stärke der Papierbahn nur verhältnismäßig gering sein, da sonst ein technisch einwandfreies Aufwickeln nicht möglich bzw. sehr schwierig ist. Ein solcher Kondensator kann daher zwischen zwei leitenden Schichten nur mit verhältnismäßig geringer Spannung beansprucht werden. Er eignet sich daher nicht als Hochspannungskondensator. Bei der Anordnung nach der Erfindung tritt dieser Nachteil dagegen nicht auf, da man zwischen den einzelnen leitenden Belägen beliebig viel Isolierschichten einzeln einwickeln, kann.According to the invention, the z. B. common from a paper tape insulating pad is a special carrier, which after the application of the conductive and semiconductive layers between the actual insulation layers is wrapped. It is already known per se as bushing insulators formed wound capacitors before assembling the capacitor the conductive To apply the covering and the semiconducting layers on a common base. This common base then forms the insulating layer between two conductive ones Toppings. In contrast, in the arrangement according to the invention between the individual conductive coverings, wrapped in special insulating layers. This has the following Advantage: If the conductive coating and the semiconducting layers are applied to the the paper web forming the insulation are applied and then this paper web is wound up, the thickness of the paper web may only be relatively small otherwise a technically perfect winding is not possible or very difficult is. Such a capacitor can therefore only be placed between two conductive layers relatively low stress. It is therefore not suitable as a high voltage capacitor. In the arrangement according to the invention, this occurs On the other hand, there is no disadvantage, as you can choose between the individual conductive coatings can wrap a lot of layers of insulation individually.
Selbstverständlich bezieht sich die Erfindung nicht allein auf reine Kondensatoren, die ausschließlich der Erzeugung von Blindleistung dienen, sondern auf alle elektrischen Vorrichtungen, die kondensatorartig gebaut sind und an denen Kondensatorwirkungen auftreten. Insbesondere bezieht sich die Erfindung auch auf Hochspannungsdurchführungen mit Kondensatoreinlagen in der Isolationshülse und auf die Nutisolierungen von mit Hochspannung arbeitenden elektrischen Maschinen, an denen das Eisen der Maschine und der Nutleiter als Elektroden eines Kondensators wirken.Of course, the invention does not relate solely to pure Capacitors that are used exclusively to generate reactive power, rather on all electrical devices that are built like a capacitor and on which Capacitor effects occur. In particular, the invention also relates to High-voltage bushings with capacitor inserts in the insulation sleeve and on the slot insulation of those working with high voltage electrical Machines on which the iron of the machine and the slot conductor are used as electrodes Capacitor act.
