Abstract

Se describe un transformador o inductor de fuerza. El devanador (31) del transformador/inductor está construido por un conductor flexible (38) que tiene medios de contención del campo eléctrico que obligan a que el campo eléctrico, debido a la corriente eléctrica en el devanado (31), quede contenido dentro de la capa aislante del conductor flexible (38). El espesor de la capa aislante del condctor flexible (38) se adapta de tal manera que el esfuerzo dieléctrico (33) sea constante por toda la longitud del devanado. El área en sección transversal de la capa aislante del conducto flexible (38) se optimiza así, proporcionando un diseno de transformador/inductor con un elevado factor de espacio (figura 3).A transformer or force inductor is described. The winding (31) of the transformer / inductor is constructed by a flexible conductor (38) that has means for containing the electric field that force the electric field, due to the electric current in the winding (31), to be contained within the insulating layer of the flexible conductor (38). The thickness of the insulating layer of the flexible condctor (38) is adapted such that the dielectric stress (33) is constant throughout the length of the winding. The cross-sectional area of the insulating layer of the flexible conduit (38) is thus optimized, providing a transformer / inductor design with a high space factor (Figure 3).
