<p>PURPOSE:To easily attach or detach composing units by increasing the length of a tank of a center connected with a telescopic function member to a branch of a center longer than a solid insulator therein when 3 phases contained simultaneously in one vessel are branched to phases. CONSTITUTION:An A unit 1 simultaneously containing three phases is connected to C units 5a-5c of phases through B units 4 branched to three phases. Main conductors 11a-11c are contained in the units 5a-5c, respectively, and connected to a D unit 6 (e.g. a primary side of a transformer) through solid insulators 9a-9c. The units 5a-5c have single phase bellows 8a, 8b and 20 to absorb dimensional tolerance to flanges 10a-10c of the unit 6. Manholes 13a-13c are provided above the units 5a-5c. Further, the length l1 of the unit 5c is longer than the length l2 of the insulator 9c including the length of a contactor 12. Thus, the units are easily moved vertically and horizontally to be rapidly disassembled and assembled.</p> |
