Description

oder dergl. Induktionsgerät mit magnetischem Wickelkern* insbesondere Ringbandkern.or the like. Induction device with magnetic Winding core * especially toroidal tape core.

Die Neuerung betrifft einen gießharzisolierten Transformator, Meßwandler odsr dergl. Induktionsgerät mit magnetischem Wickelkern, insbesondere Ringbandkern.The innovation concerns a cast resin-insulated transformer, transducer or similar. Induction device with a magnetic winding core, especially toroidal tape core.

Hierbei brgteht die Notwendigkeit, den empfindlichen Magnetwerkstoff gegen mechanische Einwirkungen zu bewahren, die insbesonders durch den Schrumpfdruck des erhärtenden Gießharzes herbeigeführt sind. Bekanntlich wirkt dieser Scharumpfdruck hauptsächlich auf die Umfangsflache des Kernes ein, d.h. bei einem Rotationskörper, radial einwärts. Es ist deshalb schon vorgeschlagen worden, nur diese beanspruch te Fläche des Kernes mit einer gummielastischen Auflage zu versehen. This brings about the need to use the sensitive magnetic material To protect against mechanical influences, in particular by the shrinkage pressure of the hardening casting resin are brought about. As is well known, this sharpening pressure works mainly on the circumferential surface of the core, i.e., for a body of revolution, radially inward. It has therefore already been suggested to claim only this te surface of the core to be provided with a rubber-elastic pad.

Das Herstellungsverfahren neht nun in der Regel so vor sich, daß zunächst dor Kern duret. eine Bandage isoliert und gleich-* zeitig flilssigkeitsdicht verschlossen wird. Daran anschließend wird die Wicklung aufgebracht und mit Gießharz getränkt. Nach Aushärtung derselben wird nach Einlegen des Polsters derThe manufacturing process now usually proceeds as follows: that first the core is allowed. a bandage isolated and equal- * is closed in a liquid-tight manner in good time. After that the winding is applied and impregnated with casting resin. To The same is hardened after inserting the cushion

Die verwendete Polsterung muß in hohen Tiaße kompreasibel sein; sie beansprucht Raum,gegebenenfalls noch einen Ausweichraum Un1: eine sehr sorgsarie Behandlung. Es nuß nämlich darauf geachtet werden, daß ihre dichte Oberflächenschicht nicht beschädigt wird und kein Gießharz in sie eindringen kann, was den totalen Verlust der Kompressibilität bedeuten würde.The upholstery used must be large enough to be compatible with; it takes up space, possibly an alternative space Un 1 : a very careful treatment. Care must be taken that its dense surface layer is not damaged and that no casting resin can penetrate into it, which would mean the total loss of compressibility.

Dien wurde neuerunrsgoaäß dadurch erreicht, daC zwischen die einzelnen Lagen den Wickelkernes GiePhnrs eingebracht ist. Das hat zur Folge, daß sich cie magnetischen Eigenschaften des Xornea r?urch äußeren mechanischen !»ruck nun nicht mehr verändern lasnen und eine Polsterung sich vollstiindig erübrigt. Bei allen hanrlcls^blichen Kernnnterialien muß der magnetische Fluß durch Luftnpnlte treten. 7/erden die Luftspalte stärker durch mechanische Druckbeanspruchung verändert, wie sie sich besonders bei radialen Dri-ckcn ergeben, so entstehen hierbei wegen der geringen Permeabilität der Luft - besonders starke Veränderungen der nagnetischen Eigenschaft-en des Kornes. Durch das neuerunpcgenäöe Einbringen vor. Gießharz werden did Luftspalte weiteotgchend aungefüllt, no daß nach den Erhärten ein starrer Kern mit zueinander nicht veränderlichen Wickel-Ingen vorgefunden wird und der demzufolge ohne Schaden zu nehmen gedrückt werden kann.Service was recently achieved by placing between the individual layers of the winding core GiePhnrs is introduced. As a result, the magnetic properties of the Xornea through external mechanical! »no longer jerks can be changed and upholstery is completely unnecessary. In all common core materials, the magnetic Stepping into the river through air pumps. 7 / earth the air gaps more strongly as a result of mechanical compressive stress it changes especially with radial pressures the low permeability of air - particularly strong Changes in the magnetic properties of the grain. By the new unspecified introduction. Cast resin did air gaps largely unfilled, no that after hardening a rigid core with mutually unchangeable winding ingene is found and consequently without damage take can be pressed.

Zweckmäßig wird man das Gießharz unter Vakuunbildung in den Kern einsaugen. ...an kann nun in einem einzigen Umguß, wobei gleichzeitig die Spulcmvicklung mit getränkt wird, das Gerät, beispieleweise einen Wandler, fertigstellen. Natürlich karin man, ohne den Rahmen der Neuerung zu verlassen, trotzdem noch mit einer Polsterung' arbeiten, die dann jedoch nur gering zu sein braucht.The casting resin is expediently placed in the under vacuum formation Soak in the core. ... an can now be cast in a single cast, whereby at the same time the bobbin winding is soaked, the device, for example a converter. Of course karin man without leaving the scope of the innovation, still work with an upholstery ', which then, however, is only slight needs.

Bei geschichteten Blechpaketen war es bereits bekannt, die einzelnen Bleche miteinander durch Gießharz zu verkleben und dieses auszuhärten. Oamit sollten jedoch die die einzelne: Bleche überbrückenden Nieten 3owie das Presst1 τ les Paketes und schließlich das Schwingen der Bleche vermieden werden. Diese Nachteile waren an sich aber schon durch die Verwendung von Bandkerntn beseitigt, so daß keine Notwendigkeit vorlag, die Bandlagen nunmehr auch noch zu verkleben.In the case of layered sheet metal stacks, it was already known to glue the individual sheets to one another using casting resin and to harden this. In this way, however, the rivets bridging the individual sheets as well as the pressing 1 τ les package and finally the oscillation of the sheets should be avoided. However, these disadvantages were already eliminated by the use of tape cores, so that there was no need to glue the tape layers together.

Zur Erläuterung der Neuerung ist 3chematisch der Aufbau eines Ringbandkernes 1 im Schnitt dargestellt, wobei mit 2 einzelne seiner Bandladen angedeutet sind, zwischen denen sich Oießhnrz befindet. PrIIs noch eine Polsterung 3 vorgesehen werden sollte, so braucht diese nur an der Außenfläche 4 ''es Xernes aufgebracht sein.To explain the innovation, the structure of a is 3 schematically Toroidal tape core 1 shown in section, with 2 some of his tape drawers are indicated, between which Oießhnrz is located. Padding 3 is still planned should be, this only needs to be applied to the outer surface 4 '' of Xernes.

Allgemein könnte rmn sagen, daß die Polsterung stetn an der oder den Außenfläche(n) eines Kernes anzuordnen ist , durch die die Achse seines geringsten Viderstandsmomentes hindurchgeht. 5 bezeichnet ein Isolierschild.General could say rmn in that the padding on the stetn or the outer surface (s) of a core is to be arranged, through which the axis passes its lowest Viderstandsmomentes. 5 denotes an insulating shield.

Jetzt braucht nnn rten Kern nur noch mit einer Spulenwicklung umgeben und alles zusammen in einer Form vergießen, um ein vollständiges Gerät, z.B. einen Wandler, zu erhalten. Der Einfachheit halber ist auf die Darstellung des fertigen Gerät« verzichtet worden.Now you only need a red core with one coil winding and potting everything together in a mold to get a complete device, e.g. a transducer. the For the sake of simplicity, the finished device is not shown.
