Abstract
PURPOSE:To reduce the noise as well as to prolong the life of the subject reactor core by a method wherein, in the reactor core with the core leg formed by laminating a plurality of block cores through the intermediary of gaps and pressed in one body by applying pressure from the upper and the lower direction, the average magnetic flux density of the gaps is equalized by adjusting the length of each gap. CONSTITUTION:A plurality of cylindrical block cores 1 radially laminated inside a tank wall 5 are laminated through the intermediary of gaps G1-G5, and after a wiring circuit 4 has been wound around, yokes 2 are arranged on the upper and the lower sides, tightened by a clamp fitting 3, and the reactor is formed. In this constitution, the roughness of surface of the upper and the lower surfaces of each block is set at 0.1mm., and the total gap length of the gaps G1-G5 is to be same as the ordinary reactor, but the length of each gap is not made uniform and formed as follows; namely, ratios are selected from G1=4.36, G2= 4.26, G3=4.10, G4=3.14, and G5=1.14; the largest magnetic flux density is given to the gap G2, the smallest density is given to the gap G5, and the average magnetic flux density is equalized.
