Abstract

L'invention concerne un dispositif permettant de bobiner un noyau toroïdal notamment fermé, avec un matériau de bobinage. Ledit dispositif présente au moins un support de bobinage à chargeur pour prébobiner et bobiner ensuite le matériau de bobinage sur un noyau toroïdal. Il est prévu, selon l'invention, pour perfectionner ledit dispositif de manière avantageuse en termes d'utilisation, que le support de bobinage à chargeur (4) entoure, dans sa section transversale, qui coupe un plan de positionnement du noyau toroïdal du dispositif (1), une cavité (6), pour loger une section transversale profilée annulaire d'un noyau toroïdal (2) pouvant être bobiné dans ledit dispositif (1) et qu'il soit ouvert ou puisse être ouvert, par sections, dans le sens périphérique. L'invention concerne en outre un procédé permettant de bobiner un noyau toroïdal (2) notamment fermé, avec un matériau de bobinage (3). Ledit matériau (3) est prébobiné pour former un support de bobinage à chargeur (36) et est bobiné sur le noyau toroïdal par transfert à partir du support de bobinage à chargeur (36). Afin de perfectionner avantageusement ledit dispositif, il est prévu selon l'invention, d'effectuer un prébobinage pour former un support de bobinage à chargeur (36), de sorte que ledit support de bobinage à chargeur (36) forme une section transversale évidée (6') intérieure comparativement supérieure à la section transversale du noyau toroïdal et renferme dedans une section de noyau toroïdal. L'invention concerne en outre des bobines de choc à noyau toroïdal et des transformateurs à noyau toroïdal pouvant être produits à l'aide dudit dispositif et selon ledit procédé.
