Claims

[Scope of Claim for Utility Model Registration] A gas insulated insulation and disconnector characterized by meeting the following conditions (a), (b), (c), (d), and (e). (a) A box-shaped operating shaft storage box 4 is installed on a mounting partition plate 3 that is integrally provided in the opening 2 of a case 1 such as a gas-insulated cubicle by welding the periphery to maintain airtightness. (b) A mechanism for opening and closing the vacuum interrupter 26 is disposed on the side surface of the mounting partition plate 3 on the outside air side. (c) Install the cylinder on the insulating gas-filled side surface of the mounting partition plate 3 in the operating shaft storage box 4 so that the two sides are sandwiched so as to maintain airtightness. One end of the operating shaft 29 that is penetrated is supported in the body 33a so as to be rotatable while maintaining an airtight seal with a rotary seal gasket 42 and a bearing 38, and the closed bearing 32 is supported by a large bolt. The shaft portion 43a of the bearing bolt body 43 is passed through the shaft opening 35 of the horizontal end plate 4b, and the flange portion 43b is pressed against the shaft opening 35 of the horizontal end plate 4b. Locknut body 3
4 are screwed in and clamped together, and installed so as to maintain airtightness. An operating device shaft 29 is installed, which is rotatably supported by a through bearing 31 and a closed bearing 32, each of which has a structure that maintains airtightness, and which is installed at each of 4a and 4b. It is composed of a bearing cylinder body 33 in which a flange part 33b is integrally formed on one end part of a hollow cylindrical cylindrical body part 33a, and a lock nut body 34 as a nut, and both horizontal end plates 4a
, 4b are properly machined to form shaft openings 35 so that the opening positions and the planes of the peripheral side surfaces are aligned in accordance with the appropriate shaft centers, respectively, and the shaft openings 35 are formed in the horizontal end plates 4a. The cylindrical body 33a is fitted into the shaft opening 35, and the other end of the shaft 29 is rotated through the lock nut body 34, which is screwed onto the flange 33b and the cylindrical body 33a. Payment should be made freely. (d) A link flat plate 30 is provided at the outwardly projecting end of the operating shaft 29 from the through bearing 31, and the link flat plate 30 is connected and interlocked with the opening/closing driving mechanism of the vacuum interrupter 26; A pressure spring lever 45 in the form of a rod that protrudes laterally is installed at a predetermined location in the operation shaft storage box 4 of the operating shaft 29, and a pressure spring 46 is attached to the free end of the pressure spring lever 45. and an insulating rod 47 so that the drive link plate 48 can be rotated by a predetermined angle. (E) The operation lever of the vacuum interrupter 26 is caused to operate in conjunction with the rotation of the drive link plate 48.
