CAPSULE DEVICE OF GAS-INSULATED HIGH VOLTAGE SWITCHGEAR WITH COMPENSATING ELEMENT

PROBLEM TO BE SOLVED: To reduce the structural length of the compensation element of a capsule device which has the compensation element between two capsule blocks. SOLUTION: A tie-rod 6 attached to a compensation element is fixed to two connection flanges 22 and 31 adjacent to both capsule block. The dimension of the compensation element 4, including fixing flanges 41 and 42, is reduced in accordance with a compensation function, so that the axial direction length (a) of the compensation element 4 can be same as the axial direction length of the fixing flange 51 of an insulator 5, which is normally attached to capsule blocks 2 and 3. With this constitution, the capsule components of the individual switchgear units of a high voltage switchgear can be placed at the centers of the center planes of the switchgear units.
