BASIC MODULE FOR MAGNETIC CORE OF AN ELECTRICAL TRANSFORMER MAGNETIC CORE COMPRISING SAID BASIC MODULE METHOD FOR MANUFACTURING SAID MAGNETIC CORE AND TRANSFORMER COMPRISING SAID MAGNETIC CORE

摘要

The present invention is a basic module of a magnetic core of a wire-type electric transformer, which is composed of a first winding (1; 2) and a second winding (3; 4) made of first and second materials, The first material is a crystalline material having a saturation magnetization (Js) of 1.5 T or more and a magnetic loss of less than 20 W / kg at a sinusoidal frequency of 400 Hz with respect to the maximum induction of 1 T. The second material is a super- (S _1, S ₂ ) of the first winding (1; 2) is a material having a magnetostriction (? _Sat ) and a magnetic loss of less than 20 W / kg at a sinusoidal frequency of 400 Hz for a maximum induction of 1 T, (S ₃ ; S ₄ ) of the first and second coils (3 and ₄ ) are set such that the ratio of the cross-sectional area of the first material having the high saturation magnetization (Js) to the cross- (S ₁ / (S ₁ + S ₃ ); S ₂ / (S ₂ + S ₄ )) is comprised between 2% and 50%, preferably between 4% and 40% basic It relates to a module. The present invention relates to a magnetic core of a transformer comprising at least one such basic module, a method for manufacturing the same, and a transformer comprising the same.
