設けたガス圧低下表示装置において、前記機構部
ケース３には表示体２４を内装するカバー部材１
９を取着し、同カバー部材１９内には一端が機構
部ケース３側の固定部に取付けられた帯状の表示
体２４を外周部に巻回した筒状体２３を配設し、
同筒状体２３内に挿脱可能に配置された表示作動
棒１８を前記ロツク棒９に連係したことを特徴と
するガス開閉器の内部圧力低下表示装置。 For the switch case 1 with a sealed structure, the same case 1
Bellows 2 expands and contracts as the gas pressure inside changes.
At the same time, the actuating rod 6 of the bellows 2 is exposed in the mechanism case 3 attached to the switch case 1, and the actuating rod 6 of the bellows 2 is always locked in the mechanism case 3. When the gas pressure in the switch case 1 decreases, the engagement is released by operating the actuating rod 6 in the opposite locking direction, and the locking rod 9 is actuated by the biasing member 14 to lock the opening/closing operation mechanism of the switch. In the provided gas pressure drop display device, the mechanism case 3 includes a cover member 1 in which a display body 24 is housed.
9 is attached to the cover member 19, and a cylindrical body 23 is disposed within the cover member 19, in which a band-shaped display body 24, one end of which is attached to a fixed part on the side of the mechanism case 3, is wound around the outer periphery.
An internal pressure drop display device for a gas switch, characterized in that an indicator operating rod 18, which is removably disposed within the cylindrical body 23, is linked to the lock rod 9.
