GIOGHI = La sezione di detti , uguale a quella de Nuc lei,venne divisa in due metà Fig. 2, e Fig.3 La prima, Fig. 2,e' costituita da lamierini magne =tici sistemati di piatto, e non di costa; sui quali sono stati ricavati tre fori a distanza interasse Nucleo Bobina, del_diametro corrispondente a quello dei Nuclei. E'assemblamento di dette strisce di la-=miera, formano metà sezione di quella totale dei Nucl ei,e rappresentano_un bloco FIG 2 con relai= =tive Nicchie.D)=C=Ε, nicchie allequaii a_blocco ultimato; è stata data una leggare conicià , non solo per_facilitare il_montaggio dei Gioghi sui NU= =clei ma sopratutto e principalmente, per aumentare la superfice di trasmissione del flusso dai Nud ei ai Sloghi, infatti; se nelle normali costruzioni di trasformatori a G-iunti affacciati, la superfice di trasmissione del flusso_è data dalla sola sezione in cmq. della superfice d'appoggio dei Nuclei, sui Gioghi_nel_caso_in_questione ,_alla_sudetta. ,superfice si aggiunge l' altra, data da S x 3.14 x H d ove H corrisponde-alla penetrazione-del tratto-di-Nucleo nella sede_relativa. Inoltre,_alle_sudette nich ie C=D=E;e ' stato necessario apportare_ i..tre taglia come_da_ F. 2, = F=G=H; in quanto_senza_di_esse comportandosi dette nicchie, come spire di.corto. GIOGHI = The section of the sayings, equal to that of Nuc lei, was divided into two halves Fig. 2, and Fig. 3 The first, Fig. 2, is made up of magnetic sheets arranged flat, and not on the edge ; on which three holes have been obtained at a distance between the core of the coil, with a diameter corresponding to that of the Nuclei. It is an assembly of said strips of sheet metal, they form half a section of the total section of the Nucl and i, and represent a FIG 2 block with relative niches. a reading conic has been given, not only to_facilitate the_mounting of the Gioghi on NU = = clei but above all and mainly, to increase the transmission surface of the flow from the Nudes to the Slogos, in fact; if in the normal constructions of transformers with facing G-joints, the flux transmission surface is given only by the section in cmq. of the support surface of the Nuclei, on the Gioghi_in_case_in_questione, _alla_sudetta. , the other surface is added, given by S x 3.14 x H d where H corresponds-to the penetration-of the tract-of-the-Nucleus in the relative_site. Furthermore, at the niches i and C = D = E; it was necessary to bring_ the .. three sizes as_from_ F. 2, = F = G = H; as_without_of_ they behave said niches, like short coils.
