<p>PURPOSE:To improve the corona resistance and the insulating performance by providing an insulating supporting body in which a space part is formed by plural members, containing a ceramic capacitor in this space part, and also, filling it with SF6 gas. CONSTITUTION:An insulator 10 is constituted of an outer tube 12 fixed to the lower flange 11, the upper flange 13 fixed to its upper part, and plural capacitors 2 attached between the flange 11 and 13, and an internal space formed by the flanges 11, 13 and the outer tube 12 is allowed to communicate with an SF6 gas atmosphere through a vent hole 15. A terminal 2a of the capacitor 2 is formed like a screw, and a terminal 2b becomes a screw hole. The flange 11 molds a fixed screw 5 and an electrode screw 14 by a cat molding epoxy resin, and the terminal 2a is screwed into a screw hole 14a. The flange 13 molds an electrode screw 16, and a screw 16b is screwed into the terminal 2b. The outer tube 12 is a cylinder made of a GFRP material, and since the capacitor 2 does not come into contact with the outer tube, it does not occur that peeling is generated in an electrode A part of the capacitor 2, and a crack is generated in a corner B part.</p> |
