Title:
THREE-PHASE ELECTROMAGNETIC EQUIPMENT
Document Type and Number:
Japanese Patent JP2016162924
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide three-phase electromagnetic equipment capable of attaining reduction in weight while suppressing a leakage magnetic flux that may be generated in main windings, and capable of varying reactance of the main windings.SOLUTION: The three-phase electromagnetic equipment comprises: a first magnetic core 11 and a second magnetic core 12 formed from three parallel winding magnetic legs 13a-13c in which control windings CW1-CW3 are individually mounted, return path magnetic legs 14a and 14b that are formed outside of the winding magnetic legs on both sides, and magnetic yoke parts that individually connect both ends of the winding magnetic legs and the return path magnetic legs; and three main windings MW1-MW3 that are mounted so as to individually surround pairs of the control windings CW1-CW3 which are opposite to each other, in the state where the first magnetic core 11 and the second magnetic core 12 are disposed in such a manner that the winding magnetic legs and the return path magnetic legs are opposite to each other. The reactance of the main windings is varied by controlling DC currents to be supplied to the control windings CW1-CW3.SELECTED DRAWING: Figure 5
