摘要： PURPOSE:To cool hollow conductors efficiently by a method wherein two adjacent layers of hollow conductor disc-type coils make one pair and one or a plurality of pairs compose one refrigerant circulation path and the outermost layer of each pair is used as a supplying end and a recovery end of the refrigerant. CONSTITUTION:A hollow conductor is wound in layers along the radius direction to form one unit of disc-type 10 or 11. These units are arranged in plural layers and two adjacent disc-type coils 10 and 11 make ne pair. One of the hollow conductors 10a and 11a which occupy the outermost layers of both unit disc-type coils 10 and 11 respectively is used as a supplying end and another is used as a recovery end of the refrigerant. The refrigrant supplied from the hollow conductor 10a circulates in the disc-type coi 10 toward the hollow conductor 10b which occupies the innermost layer to reach the hollow conductor 11b which occupies the innermost layer of the disc-type coil 11 and is recovered from the hollow conductor 11a. With above cnstitution, the circulation path can be shortened and the hollow conductors can be cooled efficiently.

摘要： PURPOSE:To reduce the eddy current loss in a hollow conductor which is wound to form a coil by a method wherein stranded wires are arranged around a hollow pipe through which cooling refrigerant is circulated. CONSTITUTION:A coil conductor 13 is composed of a hollow pipe 11 and stranded wires 12 arranged around the pipe 11. The sectional area of the hollow part 14 of the pipe 11 is determined by the quantity of refrigerant circulated through it but the sectional area of the pipe 11 is determined to be just large enough to maintain mechanical strength as a core of wire stranding. Thus the eddy current loss in this sectional area can be smaller than that in the sectional area of the conductor is not composed of stranded wires and, as the stranded conductors which generate smaller eddy current loss are arranged around the pipe, the eddy current loss of the hollow conductor 13 can be reduced as a whole.
摘要翻译：目的：为了减少中空导体中的涡流损耗，该中空导体通过一种方法缠绕以形成线圈，其中绞合线布置在冷却制冷剂循环的中空管周围。构成：线圈导体13由中空管11和布置在管11周围的绞合线12组成。管11的中空部14的截面积由循环通过其的制冷剂量决定，但截面积管道11被确定为足够大以保持机械强度作为绞线的芯线。因此，该截面积的涡电流损失可以小于导体的截面积不是由绞合线构成的，并且由于在管道周围布置产生较小涡流损耗的绞合导体，涡流损耗中空导体13整体上可以减少。

摘要： PROBLEM TO BE SOLVED: To provide a core with a gap for a reactor wherein the increase of the magnetic strain generated by the force for clamping axially the core is suppressed and noises are reduced thereby. SOLUTION: This core with a gap comprises a laminate of grain oriented silicon steel plates to form block cores 2 and yoke cores 4, 5 with non-magnetic insulators 3 for a gap interposed between the block cores 2 to form a leg core. In this case, using as the grain oriented silicon steel plate the one having an inner tension not smaller than the tension equal to 15kg/cm plus a magnetic attraction force generated by the gap, the action of a compression force applied to the grain oriented silicon steel plate in its axial direction when clamping the core is reduced to eliminate the rapid increase of a magnetic strain.

摘要： PROBLEM TO BE SOLVED: To simplify the clamp used for fastening a leg core constituted by piling a plurality of block cores upon another and, at the same time, to uniformly clamp the leg core. SOLUTION: A block core 2 is constituted by piling magnetic steel plates coated with films having an self-adhesive property upon another and a leg core 1 is constituted by piling a plurality of block cores 2 upon another. A spacer having a hole for passing a clamping stud 8 is put in the middle of each block core 2 and the stud 8 passed through the hole is passed through upper and lower yoke cores 4 and 5. Then the core 1 is fastened from the top and bottom sides with the stud 8 through a clamp. Since the force for fastening the stud 8 is directly applied to the central part of the core 2, no large bending moment is generated in the clamp and the core 2 can be fastened firmly. No such a body structure that has a high strength is required for the clamp.
