Abstract

PURPOSE: To prevent the circulating current of a core by arranging conductive material at the core legs around the core windows and on the surface of yokes and forming a short circuit.
CONSTITUTION: Conductive material 8 is inserted among a core 1, core clamping metal fitement 3, and core leg plate 2 and positioned at the location of the core legs 1a, 1b, and 1c and yoke sections 1d and 1e. These are formed as a short circuit by means of bolts and welding in a body. Accordingly, circulating current is applied so that an inverse magnetic flux ϕe which is almost equal to the leakage magnetic flux ϕ intersecting with this short circuit can be generated. As a result, the magnetic flux penetrating into the window of this short circuit is almost reduced to 0. Circulating current is not applied to the core 1 and the melting loss of the core 1 can be prevented
