Abstract

Transformador destinado, principalmente, a la alimentación de circuitos eléctricos y/o electrónicos con tensiones y corrientes alternas, que comprende un circuito magnético laminar, constituido por un apilamiento de chapas ferromagnéticas conductoras ; al menos un armazón aislante, que comprende una parte tubular, destinada a recibir en su interior una de las ramas del circuito magnético, y a soportar alrededor de su exterior, al menos dos bobinados, dispuestos uno al lado del otro a lo largo de ésta, y medios de aislamiento y de separación eléctrica de estos bobinados entre si, solidarios del armazón y realizados mediante dos delgados tabiques en forma de collarines, orientados perpendicularmente al eje geométrico de la parte tubular, estando dispuestos los citados collarines entre los extremos adyacentes de los bobinados; y una pantalla electrostática en forma de espiral plana abierta en un hilo conductor aislado, enrollado alrededor del armazón entre los citados collarines, estando uno de los extremos de este hilo eléctricamente puesto a masa; caracterizándose el citado transformador por el hecho de que la parte tubular del armazón lleva una abertura situada entre los dos collarines, y por el hecho de que la espira interior de la espiral plana comprende una parte desnuda, que penetra por esta abertura en el interior de la parte tubular, para entrar en contacto con una de las chapas que forman el circuito magnético que se halla unido a la masa.
