Strooiveldarme lektransformator.Strain-field intestine transformer.

De uitvinding heeft betrekking op een strooiveldarme lektransformator. Een lektransformator wordt bijvoorbeeld toegepast in de gelijkspanning naar wisselspanning-omzetter, zoals beschreven in de ongepubliceerde NI. o.a. nr. 8203474 van aan-5 vraagster, en in de Series Resonant Power Supply, onder andere gepubliceerd in "Proceedings of the Second International Power Conversion Conference 1980", pp. 2.8.1 - 2.8.18.. Een voldoende grote lek, d.w.z. een koppelfactor van 60 A 90% tussen primaire en secundaire spoelen, kan worden bereikt 10 door primaire en secundaire wikkeling op gescheiden spoelko-kers te wikkelen, en deze elk om het middenbeen van een E-kernhelft te plaatsen, waarbij deze helften door een lucht-spleet gescheiden zijn. Een dergelijke constructie heeft het bezwaar, dat een relatief groot strooiveld wordt opgewekt, 15 dat in andere schakelingen of sensoren stoorsignalen kan veroorzaken .The invention relates to a stray-field gut transformer. For example, a electrode transformer is used in the DC to AC converter, as described in the unpublished NI. inter alia no. 8203474 of applicant 5, and in the Series Resonant Power Supply, published inter alia in "Proceedings of the Second International Power Conversion Conference 1980", pp. 2.8.1 - 2.8.18 .. A sufficiently large leak, ie a coupling factor of 60 A 90% between primary and secondary coils, can be achieved by winding primary and secondary winding on separate coil coils, each around the the middle leg of an E core half, these halves being separated by an air gap. Such a construction has the drawback that a relatively large stray field is generated, which can cause interfering signals in other circuits or sensors.

Het doel van de transformatorconstructie, volgens de uitvinding, is een lektransformator met een klein strooiveld. Hiertoe wordt gebruik gemaakt van een gesloten potkerntransfor-20 mator met afdekschijf voorzien van twee doorvoergaten, waarin geplaatst een primaire spoel, een secundaire spoel en een magnetische shunt, die tussen beide spoelen is geplaatst.The purpose of the transformer construction according to the invention is a leakage transformer with a small stray field. To this end, use is made of a closed pot core transformer with cover disc provided with two feed-through holes, in which a primary coil, a secondary coil and a magnetic shunt, which are placed between the two coils, are placed.

De -luchtspleet bevindt zich in het middenbeen. Het strooiveld is nu in de kern opgesloten, terwijl de koppelfactor inge-25 steld kan worden door de verhouding van luchtspleet in het - * middenbeen en luchtspleet tussen shunt en middenbeen en/of buitenwand.The air gap is located in the mid leg. The stray field is now enclosed in the core, while the coupling factor can be adjusted by the ratio of air gap in the middle leg and air gap between shunt and middle leg and / or outer wall.

Claims (1)

1. Lektransformator met het kenmerk, dat primaire spoelen en secundaire spoelen om een middenbeen van een potkern-transformator zijn geplaatst, terwijl deze potkerntrans-formator geheel gesloten is, op één of enkele doorvoer-5 openingen na, waardoor de aansluitdraden van de spoelen naar buiten gevoerd kunnen worden, terwijl er een lucht-spleet in het middenbeen is opgenomen, en zich tussen primaire spoel(en) en secundaire spoel (en) een magnetische shunt bevindt, die samen met eerder genoemde lucht-10 spleet de koppelfactor tussen primaire en secundaire spoel(en) bepaalt. « 83039941. Electrical transformer, characterized in that primary coils and secondary coils are placed around a center leg of a pot core transformer, while this pot core transformer is completely closed, except for one or a few feed-through openings, through which the connecting wires of the coils can be fed outdoors, while an air gap is included in the mid-leg, and there is a magnetic shunt between primary coil (s) and secondary coil (s), which, together with the aforementioned air-10 gap, is the coupling factor between primary and secondary coil (s). 8303994
