Document Type and Number:
WIPO Patent Application WO/2018/116362
Kind Code:
A1
Abstract:
This reactor (1) is equipped with a coil (11) having a plurality of unit coils (18). First spacers (13) are disposed at least in any of the spaces between the unit coils (18), and between one of the unit coils (18) and a supporting frame (12). Second spacers (19) are disposed between the first spacers (13). The supporting frame (12), the first spacers (13), and the second spacers (19) are traversed by a bolt (15) and fixed by the bolt (15). A gap exists between the bolt (15) and the wall surface of a through-hole formed in each of the first spacers (13) wherethrough the bolt (15) passes. When the coil (11) is not energized, the spacing distance between neighboring first spacers (13) in the central axis direction of the coil (11) is greater than the thickness in the central axis direction of the unit coil (18) located between the neighboring first spacers (13).
