PROBLEM TO BE SOLVED: To reduce force applied to an air core coil in an air core type reactor with an easier configuration without impairing air permeability.SOLUTION: A first fastening member 6 is fixed to a position fixed in accordance with the degree of deformation during energization of an air core coil 2 on a bolt 5 in the inside of a hole provided in an insulation member 3 through which the bolt 5 passes. A frame 4 is driven into contact with the first fastening member 6 and the frame 4 is sandwiched by the first fastening member 6 and a second fastening member 7. By fastening the second fastening member 7, the bolt 5 and the frame 4 are fastened, and the air core 2 and the insulation member 3 sandwiched by the frames 4 are fixed.SELECTED DRAWING: Figure 2 |
