Druckgasisolierte, gekapselte Hochspannungsanlage Compressed gas-insulated, encapsulated high-voltage system
Die Erfindung bezieht sich auf eine druckgasisolierte, gekapselte Hochspannungsanlage mit vorwiegend aus Stahlblech bestehenden, längsgeschvreißten Gehäusen, die zur Unterbrechung des magnetischen Kreises einen Längsstreifen aus paramagnetischem Material aufweisen.The invention relates to a pressurized gas-insulated, encapsulated high-voltage installation predominantly made of sheet steel existing, longitudinally shredded housings that are used for interruption of the magnetic circuit has a longitudinal stripe of paramagnetic Have material.

niedrigere Herstellungskosten, aber im allgemeinen höhere Verluste als Aluminium-gekapselte Anlagen. Die Ursache hierfür ist der den Innenleiter umgebene, geschlossene Eisenkreis. Dieser Eisenkreis bewirkt bei Wechselstrom erhöhte Ummagnetisierungs- und Wirbelstromverluste.lower manufacturing costs but generally higher losses as aluminum-encapsulated systems. The reason for this is the closed iron circle surrounding the inner conductor. With alternating current, this iron circle causes increased magnetic reversal and eddy current losses.
Es ist bereits versucht worden, durch Unterbrechung des Eisenkreises die Verluste herabzusetzen. Dies geschieht z.B. nach der DT-OS 1 938 013 durch Einschweißen eines Metallstreifens aus paramagnetischem Material. Hierdurch erhöht sich der magnetische Widerstand des Eisenkreises und vermindern sich die Verluste. Das Einfügen eines Streifens aus unmagnetischem Material in die Kapselung bedingt jedoch einen gewissen Her-Stellungsaufwand. "5Q9822/0130'\"Attempts have already been made to reduce losses by breaking the iron circuit. This is done, for example, according to DT-OS 1 938 013 by welding in a metal strip made of paramagnetic material. This increases the magnetic resistance of the iron circuit and reduces the losses. However, inserting a strip of non-magnetic material into the encapsulation requires a certain amount of manufacturing effort. "5Q 9 822/0130 '\"

Die Erfindung hat das Ziel, den Herstellungsaufwand zur Unterbrechung des magnetischen Kreises herabzusetzen. Es wird deshalb vorgeschlagen, daß erfindungsgemäß die Schweißnaht aus paramagnetischem oder diamagnetischem Material besteht und den Abstand zwischen den Kanten der Kapselung überbrückt .The aim of the invention is to reduce the production costs for interruption of the magnetic circuit. It is therefore proposed that, according to the invention, the weld seam paramagnetic or diamagnetic material and the Distance between the edges of the encapsulation bridged.
Durch die Erfindung ist es möglich, den Effekt des erhöhten magnetischen Widerstands bei vermindertem Material- und Fertigungsaufwand gegenüber dem Stand der Technik zu erzielen, da nur eine, verbreiterte Schweißnaht benötigt wird und außerdem die Materialkosten für den Streifen paramagnetischen Materials entfallen. Allerdings ist die Breite der Schweißnaht gemäß der Erfindung im Verhältnis zur Wandstärke der Kapselung begrenzt. Zweckmäßig sollte der Abstand zwischen den Kanten der Kapselung das zwei- bis dreifache der Wandstärke der Kapselung betragen. Die Herstellung einer solchen Schweißnaht ist ohne besonderen Mehraufwand an Kosten möglich.The invention makes it possible to use the effect of increased magnetic resistance with reduced material and manufacturing costs to achieve compared to the prior art, since only one, widened weld seam is required and moreover the material costs for the strip of paramagnetic material are eliminated. However, the width of the weld seam is in accordance with the invention limited in relation to the wall thickness of the encapsulation. The distance between the edges of the Encapsulation be two to three times the wall thickness of the encapsulation. The production of such a weld seam is without special additional costs are possible.
Auch der durch die Flansche gebildete magnetische Kreis kann durch Einfügen einer Schweißnaht gemäß der Erfindung unterbrochen werden. Zweckmäßig weisen daher auch die Flansche eine Schweißnaht aus paramagnetischem oder diamagnetischem Material auf.The magnetic circuit formed by the flanges can also be interrupted by inserting a weld seam according to the invention will. The flanges therefore also expediently have a paramagnetic or diamagnetic weld seam Material on.

Die Stoßstelle des Mittelstücks ist durch die paramagnetische Schweißnaht 1 überbrückt. Bei Bedarf können auch die Flansche 2 mit einer Schweißnaht 4 versehen werden.In Fig. 1, the middle piece of the encapsulation, which is bent to form a tube Sections are designated with 3, the two connection flanges with 2. The joint of the middle piece is bridged by the paramagnetic weld 1. If necessary, can also the flanges 2 are provided with a weld 4.

In Fig. 2 ist mit b der Abstand zwischen den Kanten der Kapselung dargestellt». Der Abstand beträgt beim Ausführungsbeispiel etwa das dreifache der Wandstärke a. In Fig. 2, b is the distance between the edges of the Encapsulation shown ». In the exemplary embodiment, the distance is approximately three times the wall thickness a.
