In the second alternative solution, the control electrode can give way to an undesired mechanical load, such as a shock. It is thus an unintentional and possibly not directly visible damage to the control electrode, such as during transport or during assembly, during operation or during maintenance of the electrical component, largely avoided. Therefore, the control electrode of the second alternative solution increases the reliability of the electrical component according to the invention.

Bei dieser Komponente kann der elastomere Kunststoff aber auch elektrisch nichtleitend und der Überzug elektrisch leitend sein. In jedem Fall kann der elastomere Kunststoff Silikon oder EPDM enthalten. In order to enable a particularly economical production of the component according to the first alternative solution, the non-detachable connection may be embodied as an embedding, in which an end of the conductor carrying the control electrode is embedded in the hood produced by glazing.

Der Kondensatorwickel 40 weist voneinander elektrisch isolierte The capacitor winding 40 has electrically isolated from each other
Kondensatorbeläge 41 auf, die in radialer Richtung mit Abstand voneinander gehalten sind. Der isolierende Abstand wird durch eine in Form einer Spirale gewickelte Isolierfolie 42 erreicht, welche typischerweise aus Papier und/oder Kunststoff besteht, oder durch mehrere um die Achse A geführte Lagen eines fadengewickelten Wickelkörpers. Der Kondensatorwickel 40 dient der Steuerung eines elektrischen Feldes, welches sich während des Betriebs der Durchführung zwischen dem dann auf Hochspannungspotential befindlichen Stromleiter 10 und dem dann auf dem Potential des Metallgehäuses befindlichen Montageflansch 30 ausbildet.

The insulating gap is achieved by a wound in the form of a spiral insulating 42, which typically consists of paper and / or plastic, or by a plurality of guided around the axis A layers of a thread wound package. The capacitor winding 40 serves to control an electric field which is formed during operation of the bushing between the then at high voltage potential located conductor 10 and then located on the potential of the metal housing mounting flange 30. The insulating film 42 and the capacitor pads 41 of the
Kondensatorwickels 40 sind in eine im allgemeinen Füllstoff enthaltende feste Polymermasse 21 eingebettet, welche typischerweise ein mit einem Mineralpulver gefülltes Epoxid ist. Condenser coils 40 are embedded in a generally filler-containing solid polymer mass 21, which is typically an epoxy filled with a mineral powder.
Die Steuerelektrode 50 weist eine Haube 51 aus Kunststoff auf. Aus Fig.2 ist ersichtlich, dass zumindest auf der nach oben, unten und aussen weisenden, also zumindest auf der gesamten äusseren Oberfläche der Haube 51 ein Überzug 52 aus einem gehärteten Lack aufgebracht ist. Die Steuerelektrode 50 befindet sich auf dem Potential des Stromleiters 10. Dies kann zum einem durch einen die Haube 51 bildenden, elektrisch leitenden The control electrode 50 has a hood 51 made of plastic. From Fig.2 it can be seen that at least on the up, down and out facing, so at least on the entire outer surface of the hood 51, a coating 52 is applied from a cured lacquer. The control electrode 50 is at the potential of the current conductor 10. This can be done by a the hood 51 forming, electrically conductive
Kunststoff, etwa durch ein mit elektrisch leitenden Partikeln, wie Graphit-, Metall- oder Metalloxidpulver, gefülltes Polymer erreicht werden. Zum anderen kann dies auch dadurch erreicht werden, dass der den Überzug 52 bildende, gehärtete Lack elektrisch leitend ist, unabhängig davon, ob die Haube 51 aus einem elektrisch leitenden oder einem elektrisch nichtleitenden Kunststoff gefertigt ist. Der Überzug 52 aus dem elektrisch leitenden oder elektrisch nichtleitenden Lack glättet nicht zu vermeidende Oberflächenrauhigkeiten der Haube 51 . Es wird so eine besonders feine Steuerung des bei Betrieb der Hochspannungsanlage auftretenden elektrisch leitenden Feldes erreicht, das zwischen der Plastic, for example by means of electrically conductive particles, such as graphite, metal or metal oxide powder, filled polymer can be achieved. On the other hand, this can also be achieved in that the cured coating forming the coating 52 is electrically conductive, regardless of whether the hood 51 is made of an electrically conductive or an electrically non-conductive plastic. The coating 52 of the electrically conductive or electrically non-conductive lacquer smoothes unavoidable surface roughness of the hood 51. It is thus achieved a particularly fine control of the occurring during operation of the high voltage system electrically conductive field, which between the
Steuerelektrode 50 und dem Montageflansch 30 resp. dem mit diesem Flansch elektrisch leitend verbundenen Metallgehäuse wirkt. Zudem weist ein solcherControl electrode 50 and the mounting flange 30, respectively. the metal housing electrically connected to this flange acts. In addition, such a
Überzug eine polymere Matrix auf, die die Oberfläche der Steuerelektrode 50 vor mechanischer Beschädigung, wie Verkratzen, schützt und zugleich den Coating on a polymeric matrix, which protects the surface of the control electrode 50 from mechanical damage, such as scratching, and at the same time
unerwünschten Austritt von Elektronen aus der Steuerelektrode 50 erheblich reduziert. Wird der Überzug 52 vom gehärteten Leitlack gebildet, so sind auf Hochspannungspotential befindliche, elektrisch leitfähige Partikel des Lacks in die polymere Matrix eingebettet und wird auch dann der unerwünschte Austritt von Elektronen erheblich gemindert. unwanted leakage of electrons from the control electrode 50 significantly reduced. If the coating 52 is formed by the hardened conductive ink, electrically conductive particles of the paint located at high-voltage potential are embedded in the polymeric matrix, and even then the unwanted leakage of electrons is considerably reduced.
Die Haube ist in axialsymmetrischer Anordnung am unteren Ende des Stromleiters 10 befestigt und schirmt mit ihrer nach unten offenen, kugelförmig gekrümmten Wand eine Strom leiterverbindung ab, mit der der Stromleiter 10 mit seinem unteren Ende 12 mit dem Ende des vorgenannten, in einem isoliermittelgefüllten Metallgehäuse angeordneten Stromleiters des elektrischen Apparates elektrisch leitend verbunden ist. The hood is mounted in axial symmetry arrangement at the lower end of the conductor 10 and shields with its downwardly open, spherically curved wall from a current conductor connection, arranged with the current conductor 10 with its lower end 12 to the end of the aforementioned, in a insulator-filled metal housing Conductor of the electrical apparatus is electrically connected.
Bei der Ausführungsform nach den Figuren 1 und 2 ist die Steuerelektrode 50 nichtlösbar mit dem Stromleiter 10 verbunden. Die nichtlösbare Verbindung ist als Einbettung ausgeführt, bei der das die Steuerelektrode 50 tragende Ende 12 des Stromleiters 10 in die durch Glessen gefertigte Haube 51 eingebettet ist. In the embodiment according to FIGS. 1 and 2, the control electrode 50 is non-detachably connected to the current conductor 10. The non-detachable connection is embodied as an embedding, in which the end 12 of the current conductor 10 carrying the control electrode 50 is embedded in the hood 51 made by glazing.
Mit Vorteil ist die Haube 51 aus einem elastomeren Kunststoff geformt. Die Haube 51 kann dann durch Eingeben einer fliessfähigen Ausgangsmasse in eine Advantageously, the hood 51 is formed of an elastomeric plastic. The hood 51 can then by entering a flowable starting material in a
Giessform, die zugleich auch der Fertigung der Beschirmung dienen kann, vorgeformt werden. In einem nachfolgenden Vernetzungsprozess wird in der Giessform eine Haube 51 und gegebenenfalls zugleich auch eine Beschirmung 60 aus dem elastomeren Kunststoff erreicht. Die Beschirmung 60 ist dann direkt (in Fig.1 nicht dargestellt) auf den starren Isolierkörper 20 aufgegossen. Falls die fliessfähige Ausgangsmasse einen elektrisch leitende Partikel enthaltenden Kunststoff aufweist, kann die Haube 51 nach Auftragen eines Überzugs 52 aus einem gehärteten, elektrisch nichtleitenden Lack auf die nach aussen weisende Fläche der Haube als Steuerelektrode 50 verwendet werden. Sind die Haube 51 und die Beschirmung gemeinsam in einer Giessform gebildet worden, dann ist die Haube 51 zumindest auf der nach aussen weisenden Oberfläche mit einem Überzug 52 aus einem gehärteten, elektrisch leitenden Lack zu versehen. Bei einer unerwünschten mechanischen Belastung, etwa bei einem Stoss, kann sich die Steuerelektrode 50 elastisch verformen. Eine Beschädigung der Mold, which can also serve the production of the shield, are preformed. In a subsequent cross-linking process, a hood 51 and possibly also a shield 60 is simultaneously formed in the casting mold reached from the elastomeric plastic. The shield 60 is then poured directly (not shown in Figure 1) on the rigid insulating body 20. If the flowable starting material comprises a plastic containing electrically conductive particles, the hood 51 can be used as a control electrode 50 after applying a coating 52 of a cured, electrically non-conductive paint on the outwardly facing surface of the hood. If the hood 51 and the shielding have been formed together in a casting mold, then the hood 51 is to be provided with a coating 52 of a hardened, electrically conductive lacquer, at least on the outwardly facing surface. In case of an undesired mechanical load, such as a shock, the control electrode 50 can deform elastically. Damage to the
Steuerelektrode beim Transport oder bei der Montage der Komponente kann so weitgehend vermieden werden. Geeignete Elastomere sind vor allem Silikon und EPDM, aber auch elastomere Thermoplaste, wie etwa thermoplastisches Control electrode during transport or during assembly of the component can be largely avoided. Suitable elastomers are, above all, silicone and EPDM, but also elastomeric thermoplastics, such as thermoplastic
Polyurethan. Polyurethane.
Die Haube 51 kann aber auch in einer den starren Isolierkörper 20 und die Haube 51 , gegebenenfalls zugleich auch die Beschirmung 60, formenden Giessform gebildet werden, in welche wie etwa in WO 2009/053147 A1 beschrieben, ein den Stromleiter 10 und den Kondensatorwickel 40 enthaltender Wickelkörper angeordnet und unter Vakuum mit der fliessfähigen Polymermasse imprägniert wird. Nachfolgend wird die fliessfähige Polymermasse in der Giessform unter Bildung der festen Polymermasse 21 und damit auch unter Bildung des starren Isolierkörpers 20 und der formbeständigen Haube 51 , gegebenenfalls auch der Beschirmung 60, gehärtet. In den so gebildeten, den Stromleiter 10, den However, the hood 51 may also be formed in a mold forming the rigid insulating body 20 and the hood 51, if appropriate also the shielding 60, into which, as described for example in WO 2009/053147 A1, a casting conductor 10 and the capacitor winding 40 are contained Winding body arranged and impregnated under vacuum with the flowable polymer composition. Subsequently, the flowable polymer composition in the casting mold to form the solid polymer mass 21 and thus also to form the rigid insulating body 20 and the dimensionally stable hood 51, optionally also the shield 60, cured. In the thus formed, the conductor 10, the
Isolierkörper 20, den Kondensatorwickel 40, die Haube 51 und gegebenenfalls auch die Beschirmung 60 enthaltenden Formkörper wird spanabhebend ein Sitz für den Montageflansch 30 eingeformt und wird zumindest auf die Aussenfläche der Haube 51 der Überzug 52, etwa mit Hilfe des Leitlacks, aufgebracht. Insulating body 20, the capacitor winding 40, the hood 51 and optionally also the shield 60 containing molded body is machined a seat for the mounting flange 30 and is applied at least on the outer surface of the hood 51 of the coating 52, such as with the aid of Leitlacks.
Bei den Ausführungsformen nach den Figuren 3 und 4 ist die Verbindung zwischen dem unteren Ende des Stromleiters 12 und Steuerelektrode 50 lösbar ausgebildet. Wie in Fig.3 dargestellt, ist die lösbare Verbindung als In the embodiments of Figures 3 and 4, the connection between the lower end of the conductor 12 and the control electrode 50 is detachably formed. As shown in Fig.3, the releasable connection is as
Schraubverbindung ausgeführt. Ersichtlich weist dann die Steuerelektrode 50 ein Gewinde 54 auf, welches auf ein Gegengewinde 14 aufgeschraubt ist, das in das Ende 12 des Stromleiters eingeformt ist. Wie in Fig.4 dargestellt, kann die lösbare Verbindung auch als Schnappverbindung ausgeführt sein. Ersichtlich weist dann die Steuerelektrode 50 einen ringförmig ausgebildeten Innenrand 53 auf, der beim Aufschieben der separat gefertigten Steuerelektrode 50 in eine Ringnut 13 einschnappt, die in das untere Ende 12 des Stromleiters eingeformt ist. Screwed executed. As can be seen, then the control electrode 50 has a thread 54 which is screwed onto a mating thread 14 which in the End 12 of the conductor is formed. As shown in Figure 4, the releasable connection can also be designed as a snap connection. As can be seen, then the control electrode 50 has an annular inner edge 53 which snaps when sliding the separately manufactured control electrode 50 in an annular groove 13 which is formed in the lower end 12 of the conductor.
Aus Fig.5 ist ersichtlich, dass bei Ausbildung der elektrischen Komponente als Schottungsisolator einer gasisolierten, metallgekapselten Hochspannungsanlage der Stromleiter 10 analog den vorstehend beschriebenen Durchführungen im Isolierkörper 20 befestigt und mit Hilfe des Montageflansches 30 in die nicht dargestellte Metallkapselung eingesetzt und so in einem definierten Abstand zur Kapselung gehalten ist. Die Steuerelektrode 50 ist am linken Ende 12 des durch den scheibenförmig ausgebildeten Isolierkörper 20 geführten Stromleiters 10 befestigt. An diesem Ende kann der Stromleiter 10 mit einem in der From Figure 5 it can be seen that when training the electrical component as a barrier insulator of a gas-insulated, metal-enclosed high-voltage system, the current conductor 10 is analogous to the above-described bushings in the insulating body 20 and inserted using the mounting flange 30 in the metal enclosure, not shown, and so at a defined distance is held for encapsulation. The control electrode 50 is attached to the left end 12 of the guided through the disc-shaped insulating body 20 conductor 10. At this end, the conductor 10 with a in the
Metallkapselung angeordneten, entlang der Achse A geführten Stromleiter der Hochspannungsanlage, etwa durch Stecken, elektrisch leitend verbunden werden. In entsprechender Weise kann auch am nicht dargestellten rechten Ende des aus der Scheibe 20 herausgeführten Stromleiters 10 eine weitere Steuerelektrode angeordnet sein. Ersichtlich ist die Steuerelektrode 50 durch Aufschnappen, also lösbar, mit dem Stromleiter 10 verbunden. Sie kann aber auch in nichtlösbarer Weise mit dem Stromleiter 10 verbunden sein. Die Haube 51 wird dann beim Vergiessen der zur Fertigung des Isolierkörpers 20 vorgesehenen fliessfähigen Polymermasse gefertigt. Die feste Polymermasse 21 der Haube 51 bettet dann das Ende 12 des Stromleiters 10 unter Bildung der nichtlösbaren Verbindung ein. Metal encapsulation arranged along the axis A guided conductor of the high voltage system, such as by plugging, are electrically connected. In a corresponding manner, a further control electrode can also be arranged at the right end, not shown, of the lead-out conductor 20, which is not shown. As can be seen, the control electrode 50 is connected to the conductor 10 by being snapped on, that is releasably. But it can also be connected in a non-detachable manner with the conductor 10. The hood 51 is then manufactured during the casting of the intended for the production of the insulating body 20 flowable polymer composition. The solid polymer mass 21 of the hood 51 then embeds the end 12 of the conductor 10 to form the non-releasable connection.
Je nach Anforderungsprofil der elektrischen Komponente kann die Depending on the requirement profile of the electrical component, the
Steuerelektrode 50 lediglich am unteren resp. linken 12 oder am oberen resp. rechten Ende 1 1 des Stromleiters 1 1 angebracht sein, oder kann an jedem der beiden Enden 1 1 , 12 jeweils eine Steuerelektrode befestigt sein.
