<p>PURPOSE:To miniaturize the insulation member that constitutes a support column and make it possible to standardize it in an air-core reactor with magnetic shield that consists of upper and lower yoke sections on the outer circumference and right and left leg sections by stacking a plurality of insulation discs consisting of many non-magnetic bodies in the inside and making those discs play the role of a support column and supporting the upper and lower yoke sections with the column. CONSTITUTION:An insulation cylinder 11 is arranged inside a cylindrical reactor so as to lay it along the axial direction of the reactor. Many insulation discs 12 are stacked in the direction of their thickness from the lower yoke section 4a to the upper yoke section 4b. Here those discs are made of ceramic procelain that has a small compression strain, and in the gap that is formed between the top disc 12 and the upper yoke 4b a compressed coil spring is inserted. With said construction the upper and lower yokes are supported by the column formed by the stacked discs to prevent vibration at the yoke sections 4a and 4b.</p> |
