Description

Zur Fortleitung hochgespannter elektrischer Ströme bis zu ioo ooo Volt Spannung benutzt man gewöhnlich Leitungen, die mittels Gliederisolatoren von Masten aus Holz, Eisen oder Beton getragen werden. Es ist auch schon vorgeschlagen worden, aus mehreren Teilen bestehende Maste zu verwenden, deren einzelne voneinander isolierte Abschnitte durch ein Rohr verbunden sind. ίο Es wurde nun gefunden, daß man die Ableitung des elektrischen Stromes ganz oder fast ganz vermeiden kann, wenn man die Maste aus einzelnen Teilen herstellt und die Isolierstellen als Plattenkondensatoren ausbildet. Dadurch wird erreicht, daß an den Verbindungsstellen starke Kondensatorwirkungen auftreten.For the transmission of high voltage electrical currents up to 100,000 volts cables are usually used, which are connected to wooden masts by means of sectional insulators, Iron or concrete can be worn. It has also been suggested out of several Divide existing masts to use their individual sections isolated from one another are connected by a pipe. ίο It has now been found that one can derive the of the electric current can be completely or almost completely avoided if the masts are made from individual parts and the Forms insulation points as plate capacitors. This ensures that the Connection points strong capacitor effects occur.

In Abb. ι ist ein solcher Mast dargestellt. Die einzelnen Teile I1 2, 3, 4, 5 des Mastes sind oben oder unten mit geschlitzten Flanschrohren 6, 7 versehen. Die Schlitze 9 derselben sind aus Abb. 3 ersichtlich; die Flanschrohre werden mit den Schellen 8 durch Anziehen der Schrauben 10 fest um den Mast gepreßt. Nachdem eine Isolierscheibe 11 genügender Stärke zwischen die Flanschen 6 und 7 zweier Mastteile gelegt ist, werden die Flanschen mit isolierten Schrauben 12 (s. Abb. 2) zusammengezogen. Die Isolierscheibe 11 muß so groß gehalten werden, daß ein Überspringen des elektrischen Stromes von Flansch zu Flansch ausgeschlossen ist. Diese Verbindungsstelle wird durch eine Kappe 16 gegen Witterungseinflüsse, Regen usw. geschützt.Such a mast is shown in Fig. The individual parts I 1 2, 3, 4, 5 of the mast are provided with slotted flange tubes 6, 7 at the top or bottom. The slots 9 of the same can be seen from Fig. 3; the flange pipes are pressed tightly around the mast with the clamps 8 by tightening the screws 10. After an insulating washer 11 of sufficient thickness has been placed between the flanges 6 and 7 of two mast parts, the flanges are pulled together with insulated screws 12 (see Fig. 2). The insulating washer 11 must be kept so large that the electric current cannot jump from flange to flange. This connection point is protected from the weather, rain, etc. by a cap 16.

Man kann die \rerbindung der Flanschen 6 und 7 auch so herstellen, daß man, wie in Abb. 3 dargestellt ist, zwei ineinandergreifende Ösenschrauben 13, 14 in einen Block 15 aus Isoliermaterial so einvulkanisiert, daß die Schrauben voneinander isoliert nach entgegengesetzter Richtung stehen. Man wählt die Höhe dieses Isolierblockes 15 so groß, daß ein Überspringen des elektrischen Stromes nicht stattfinden kann.One can 6 and 7 also make the \ r Getting Connected to the flanges so that, as shown in Fig. 3, two interlocking eyebolts 13, 14 vulcanized into a block 15 of insulating material so that the coil insulated from each other are provided in opposite directions . The height of this insulating block 15 is chosen so large that the electric current cannot jump over.

Die Kondensatorenwirkung kann man noch dadurch erhöhen, daß man, wie in Abb. 5 dargestellt, eine oder mehrere dünne Metallplatten 17 in die Isolierplatte einbettet. Hierdurch wird erreicht, daß die auftretende Spannung ganz wesentlich herabgemindert wird.The capacitor effect can be increased by, as shown in Fig. 5, embeds one or more thin metal plates 17 in the insulating plate. Through this it is achieved that the stress that occurs is reduced quite significantly will.

Anstatt die Metallplatten, wie in Abb. 5 dargestellt, in die Isolierplatte 11 einzubetten, kann man die Anordnung auch so treffen, daß abwechselnd eine Isolierplatte und eine Metallplatte, dann wieder eine Isolierplatte und so fort, ähnlich wie bei einem Kondensator, aufeinandergelegt werden.Instead of embedding the metal plates in the insulating plate 11 as shown in Fig. 5, the arrangement can also be made in such a way that an insulating plate and a metal plate alternate then again an insulating plate and so on, similar to a capacitor, placed one on top of the other will.

Die einzelnen Teile der Maste können in dieser Weise nicht nur bei Holzmasten, sondern auch bei Gittermasten, wie in Abb. 4 dargestellt, und bei Betonmasten verbunden werden. The individual parts of the masts can in this way not only with wooden masts, but also with lattice masts, as shown in Fig. 4, and with concrete masts.
