Description
Claims (5)
- 筐体の内部に少なくとも開閉器ユニットが収納されていると共に、前記筐体の上部に、該筐体と開口部を介して連通しているベンチレータを有し、
前記ベンチレータは、通常運転時には、前記筐体の側方下部に設けられている吸気口から吸気された外気で前記開閉器ユニットを冷却した後の温められた空気を外部に排出する換気口と、前記ベンチレータの上方に形成されている前記開口部を覆うように設置され、内部アーク発生時には、該内部アーク発生時に発生する高温・高圧ガスを、そのガス圧により開放されて外部に放出する放圧板とを備え、前記換気口の内部側には、内部アーク発生時に発生する高温・高圧ガスの前記換気口からの流出を防止するシールド板が設置されていることを特徴とする開閉装置。 - 請求項1に記載の開閉装置において、
前記シールド板は、前記換気口を塞ぐ大きさであることを特徴とする開閉装置。 - 請求項1又は2に記載の開閉装置において、
前記シールド板は、複数枚設置されていることを特徴とする開閉装置。 - 請求項3に記載の開閉装置において、
複数枚設置されている前記シールド板は、水平方向に互い違いとなるように設置されていることを特徴とする開閉装置。 - 請求項1乃至4のいずれか1項に記載の開閉装置において、
前記換気口は、複数の小孔或いはスリットから成ることを特徴とする開閉装置。
