<p>PURPOSE:To reduce a non-magnetic material by joining together the ends of non-magnetic materials each of the inner wall for fixing a current transformer and the base plate for the inner wall at the joint. CONSTITUTION:The inner wall 8 for fixing a current transformer consists of a non-magnetic part 8a and a magnetic part 8b each region being divided in the direction of the axis and the base plate 10 for the inner wall consists of a non-magnetic part 10a and a magnetic part 10b each region being divided by a required angle from the center. The non-magnetic parts 8a, 10a are joined together at the welded part of the inner wall 8 and the base plate 10. In this construction, a magnetic path is cut by the joint of non-magnetic materials from the inner wall to the base plate, the rise of temperature due to the formation of magnetic path can be restrained and the amount of the non-magnetic material can be reduced.</p> |
