Abstract
Procedimiento para la fabricación de transformadores planares y transformador planar fabricado de acuerdo con el mismo. El transformador planar comprende una sucesión de bobinados en apilamiento constituido por un número variable de placas de panel de bobinado de circuito impreso y bobinados de cobre, laminares troquelados o de devanado, con interposición de elementos laminares aislantes en contacto con todas las caras de los bobinados y de grosor variable para ajustar los intersticios entre bobinados, estando conectados entre sí dichos bobinados mediante clavijas de conexión unidas solidariamente a los mismos, y constituyendo un bloque único por estar embebida la totalidad de los elementos laminares apilados en una masa única de resina aislante que recubre exteriormente el conjunto de elementos apilados y que queda introducida en los intersticios horizontales entre los bobinados.Procedure for the manufacture of planar transformers and planar transformer manufactured in accordance with it. The planar transformer comprises a succession of stacked windings consisting of a variable number of printed circuit winding panel plates and copper windings, stamped or winding laminations, with interposition of insulating laminar elements in contact with all winding faces and of variable thickness to adjust the interstices between windings, said windings being connected to each other by means of connecting pins jointly joined to them, and constituting a single block because all the laminar elements stacked in a single mass of insulating resin are embedded. externally it covers the set of stacked elements and that is introduced in the horizontal interstices between the windings.
