Claims (1)
、前記絶縁ガスの圧力が予め設定された圧力まで
上昇した時に動作する放圧板を取付けたガス絶縁
開閉器の放圧装置において、 前記放圧板の外側に、前記密閉容器より放出さ
れた絶縁ガス流の方向を、密閉容器の壁に沿う方
向に制御することのできる保護板を取付けたこと
を特徴とするガス絶縁開閉器の放圧装置。[Scope of Claim for Utility Model Registration] Release of a gas insulated switch which is equipped with a pressure relief plate that operates when the pressure of the insulating gas rises to a preset pressure at the outlet of a closed container filled with an insulating gas. In the gas insulation device, a protection plate is attached to the outside of the pressure relief plate to control the direction of the insulating gas flow discharged from the airtight container in a direction along the wall of the airtight container. Pressure relief device for switchgear.
