Abstract

PURPOSE: To reduce stray load loss and local heating of a structural body of the variable reactor to be caused by leakage flux by a method wherein on an assembled body consisted of accumulation of core blocks being performed with DC winding, an AC winding is wound around the core blocks thereof concentrically centering around a center hole.

CONSTITUTION: The core block 91 consisted of the core block 90 being wound around with the winding 4 consisted of a winding insulator 41, a conductor 40 are accumulated and are assembled. The winding 4 is wound toroidally around the winding core shaped ring type core block 90 as to surround the core interposing spaces at every plural windings utilizing the center hole 12, and as a result the face of the core blocks 90 between every plural windings is made to low by one step forming gaps 14, and oil pathes are formed between the upper and the lower core blocks being performed winding when the core blocks 91 are accumulated. Accordingly the variable reactor wherein crossed and connected core are not used is constituted, and stray load loss and local heating of the structural body to be caused by leakage flux can be reduced.
