Description
Flüssigkeitsisolierte Transformatoren oder Drosselspulen mit schalldämmender Kesselabdeckung Die Erfindung bezieht sich auf flüssigkeitsisolierte Transformatoren oder Drosselspulen, bei denen die Isolierflüssigkeit die durch die Magnetostriktion des Eisenkerns hervorgerufenen Schwingungen auf große schwingungsfähige Flächen des Kessels überträgt, welche durch schalldämmende Stoffe abgedeckt sind, mit im Bereich der schwingungsfähigen Flächen des Kessels derart geringer Wandstärke, daß die Flächen nicht mehr die für das Evakuieren erforderliche mechanische Festigkeit besitzen und beim Evakuieren durch eine ein freies Ausschwingen im Normalbetrieb nicht behindernde Haltekonstruktion stützbar sind, und mit in Abstand von diesen Flächen auf Trägern angeordneten, nicht schwingungsfähigen Platten hoher Werkstoffdämpfung zur Abdeckung dieser Flächen nach Patent 1233 937.Liquid-insulated transformers or reactors with sound-absorbing Boiler Cover The invention relates to liquid-insulated transformers or choke coils, in which the insulating liquid is caused by magnetostriction of the iron core caused vibrations on large vibrating surfaces of the boiler, which are covered by sound-absorbing materials, with im Area of the vibratory surfaces of the boiler so thin that the surfaces no longer have the mechanical strength required for evacuation own and when evacuating by a free swing in normal operation non-hindering retaining structure can be supported, and at a distance from these Non-vibratory panels with high material damping properties arranged on beams to cover these areas according to patent 1233 937.
Die auf den biegeweichen Flächen der Transformatorkesselwand angeordnete Haltekonstruktion zur Stützung der Wandteile mit sehr geringer Wandstärke, die aus Federelementen, Haltern und Querträgern besteht, bewirkt nun eine Dämpfung, die das freie Ausschwingen dieser biegeweichen Flächen behindert; noch mehr vermindert sich die Schwingungsamplitude allerdings durch die bei der Schwingung im Blech auftretenden Zugspannungen in Längsrichtung des Blechs.The one arranged on the flexible surfaces of the transformer tank wall Holding structure to support the wall parts with very low wall thickness, which are made of There is spring elements, holders and cross members, now causes damping that hinders the free swinging of these flexible surfaces; diminished even more However, the oscillation amplitude changes due to the oscillation in the sheet metal Tensile stresses in the longitudinal direction of the sheet.
Die Aufgabe besteht darin, diesen Längszug entweder zu eliminieren oder stark zu vermindern. Auf die Haltekonstruktion kann hingegen nicht verzichtet werden.The task is to either eliminate this longitudinal pull or greatly diminish. On the other hand, the support structure cannot be dispensed with will.
Die Aufgabe wird dadurch gelöst, daß die Flächen 2, 3, 4, 5 mit dem Kessel 1 über federnde Bauelemente 12 verbunden sind.The object is achieved in that the surfaces 2, 3, 4, 5 with the Boiler 1 are connected via resilient components 12.
Vorteilhaft wird als federndes Bauelement ein U-Profil verwendet, dessen einer Schenkel starr mit dem Kessel und dessen anderer Schenkel schwingend mit den biegeweichen Flächen verbunden ist und gleichzeitig als Träger für die nicht schwingungsfähigen Platten hoher Werkstoffdämpfung dient.A U-profile is advantageously used as the resilient component, one leg of which swinging rigidly with the kettle and its other leg is connected to the pliable surfaces and at the same time as a carrier for the not vibratory plates with high material damping are used.
Die Figur zeigt eine Ausführungsform der Erfindung.The figure shows an embodiment of the invention.
An dem Trafokessel sind die U-Profile 12 mit einem Schenkel angeschweißt. Die freien Schenkel tragen an ihrer unteren beweglichen Kante die Bleche 2, 3, 4, 5, die so dünn sind, daß an diesen Stellen die Isolierflüssigkeit frei ausschwingen kann. An der oberen Kante des U-Profils 12 sind Querträger 8 angebracht, durch die schraubenähnliche Bolzen 9 hindurchführen. Diese Bolzen 9 verhindern ein zu starkes Durchbiegen der Bleche 2, 3, 4, 5 beim Evakuieren. Sie sind entweder direkt oder durch Federelemente 19 auf den Platten 2, 3, 4, 5 befestigt. Die Befestigung der Platten 3, 4, 5, hier nur schematisch eingezeichnet, geschieht analog der Platte 2.The U-profiles 12 are welded to the transformer tank with one leg. The free legs carry the sheets 2, 3, 4, 5, which are so thin that the insulating liquid oscillates freely at these points can. At the upper edge of the U-profile 12 cross members 8 are attached through which Guide screw-like bolts 9 through. These bolts 9 prevent too strong Bending of sheets 2, 3, 4, 5 during evacuation. They are either direct or attached to the plates 2, 3, 4, 5 by spring elements 19. The attachment of the Plates 3, 4, 5, shown here only schematically, are analogous to the plate 2.
Mit Hilfe der Anordnung gemäß der Erfindung kann die Schwingungsfähigkeit der biegeweichen Platten beträchtlich erhöht und damit die Dämpfungswirkung der gesamten Anordnung gegen störende Geräusche entsprechend gesteigert werden.With the help of the arrangement according to the invention, the ability to vibrate of the pliable plates increased considerably and thus the damping effect of the entire arrangement can be increased accordingly against disturbing noises.
