Description
以下では、ガス放電管(GDT)および金属酸化物バリスタ(MOV)の機能を持つアセンブリと、アークフォルト回路遮断器(AFCI)とを組み合わせて過電圧保護機能を実現する例を開示する。このような過電圧保護機能は、交流(AC)線間電圧のスウェルなどの事象に対して有効である。
以下では、統合型サージプロテクタ(例えば、サイリスタ統合型サージプロテクタ(TISP))および過渡状態ブロッキングユニット(TBU)のようなクローバ(crowbar)回路保護デバイスを協調して使用し、自己保護および自己リセットによる過電圧保護機能を提供することに関する例を開示する。このような過電圧保護機能は、雷、サブサーキットの故障および/または交流(AC)線間の電圧スウェルなどの事象に対して有効である。なお、TISP素子は一例であるにすぎず、他の電圧保護デバイス(ガス放電管(GDT)、金属酸化物バリスタ(MOV)、過渡電圧サプレッサ(TVS)など)も利用できることを理解されたい。
