Description
本出願はカーティス・エー・バーンバックによる電磁パルス保護のための方法および装置と題する2008年9月19日付米国特許出願第61/192,591号から優先権を主張する。
本発明は,例えば核爆発や太陽嵐などにより発生する超常電磁パルス(EEMP)が電力発電系および送電系の電気部品に到達して動作できないようにするのを防止するための方法および装置に関連する.さらに詳しく説明すると,超常電磁パルス(EEMP)は電力系の部品に到達してこれを動作できなくする十分な強度を備えた核爆発(NEMP)や、非核電磁パルス(NNEMP)で発生するような、集合的にEMPと呼ばれるトランジェント・パルス、または太陽嵐によるコロナ質量放出の結果としての地磁気誘導電流(GIC)と定義される。本発明のさらなる態様はGICパルスの検出に使用することができる高速電流シャントに関連する。
現代社会に対する電力系の重要な性質は十分に認識されている。例えば、電磁パルス(EMP)攻撃による米国に対する脅威評価委員会の報告によると、重要な米国内インフラストラクチャについて、米国政府印刷局、2008年4月では、17ページで以下のように述べている。
1.機器の製造をガイドしてEEMPイベントから電力系の電気部品を保護するリアルタイム・モニタリング手段を提供する。
2.制御回路用に高速出力を提供する。
3.システムオペレータにEEMPイベントを通知する高速出力を提供する。
従って、高速電流パルス測定用の直接技術を提供するのが望ましい。
本発明の1つの態様では超常電磁パルスが電力供給システムの電気部品に到達してこれを動作不能にするのを防止するための方法および装置を提供し、電気部品はパルスを受電する電力供給システムの導電路上に位置するものとする。本発明の方法および装置はパルスが電気部品に到達して動作不能にする前に導電路上でのパルスの存在を検出するステップ又は手段を含む。パルスが電気部品に到達してこれを動作不能にする前に電気部品に対して低インダクタンス大電流容量回路を用いて電気部品から迂回させる。
図1Aから図1Cは電力送電グリッドの代表的な部分を示し、またグリッドが受電する可能性のある超常電磁パルス(EEMP)の様々な種類を示す。
Z=電流測定領域171のインピーダンス
lth=電流測定領域171の長さ
W=導電性ストリップ170の幅
t=導電性ストリップ170の厚み
f=周波数(立ち上がり時間)
μ=導電性ストリップ171の透磁率(H/m)
σ=導電性ストリップ171の導電率(1/Ω−m)
注:空気中で動作する銅製シャントでは透磁率は1とする。
