TRANSFORMER HAVING BINDING MEANS

摘要

The present invention relates to a transformer having a binding means. The transformer having a binding means comprises: a plurality of legs (10); a yoke (20) which is disposed on at least one side of an upper portion or a lower portion of the legs (10); a frame (50) which surrounds both outer surfaces of the yoke (20); and a binding means (90) which surrounds the yoke (20). The binding means (90) surrounds and fixes the outer surfaces of the yoke (20) in a direction perpendicular to the longitudinal direction and surrounds and strongly adheres to the yoke (20) at a position corresponding to an edge of a connection portion of the leg (10) and the yoke (20). According to the present invention, the outer surfaces of the yoke (20) constituting the transformer is pressurized by the binding means (90) so that gaps between a plurality of iron cores configuring the yoke (20) and the legs (10) are closely contacted, thereby reducing a noise caused by a harmonic wave. It is possible to prevent output degradation by reducing air gaps between the iron cores.
