<p>PURPOSE:To reduce the size and to make a transmitting mechanism for opening and closing operation have no conversion of rotation axes, by uniting each-phase operation converting parts with first uniting members so as to be approximately on the same straight line, and uniting a device for operating 3-phase switches collectively to the operation converting part of a single-phase switch so as to be approximately on the same straight line along with the first uniting members. CONSTITUTION:A rack 6 and a pinion 7 biting a movable contact 9 with the axis meeting at right angles convert the movable contact 9 into a linear motion. The pinion 7 is fitted to a pinion shaft 17, and insulating rods 11 and 11a fixed to its both ends are fixed furthermore to movable rods 13 and 13a respectively. The movable rods 13 and 13a are rotation-sealed with sealing members 14 and 14a for openings 20 and 20a of a tank 2 respectively, and led outside. Each disconnector 100 such as this unites the movable rods 13 and 13a led out from the tank 2 to an operating device through the medium of uniting rods, and a rack 6 and a pinion 7 of each phase are united approximately on the same straight line. Accordingly, a rotation axis converting mechanism can be eliminated.</p> |
