Claims (3)
- 回転翼先端から回転翼根まで、さらにはアースまで、放電装置を介して雷電流を案内するために、少なくとも1つの雷電流受部が各々の回転翼に位置付けられ、前記回転翼に位置決めされるそれぞれの前記電気システムと、前記回転翼に位置決めされる前記放電装置の部分との間で、少なくとも1つの過電圧アレスタが配置されている、風力タービンの回転翼に組み込まれる電気システムにおける雷電流分布に影響を与えるための方法であって、
それぞれの追加インピーダンスによって、雷の事象において前記電気システムを流れる部分電流が低減され、前記追加インピーダンスは、この場合、雷の事象において、前記電気システムと前記放電装置との間に結果生じる電位差が、それぞれの前記電気システムの絶縁耐力と、それぞれの前記電気システムと前記放電装置との間での必要とされる分離距離とに適合されるように設計され、
前記追加インピーダンスおよびその電気的相互接続は、前記追加インピーダンスを上回る電圧降下を維持するように、および、大きな雷電流勾配の場合にそれぞれの前記電気システムと前記放電装置と間の電位差を低く維持するように、低インダクタンスのものとなるように形成され、
必要な全体の前記追加インピーダンスは、電圧降下を制限するためのそれぞれの電流経路にわたっていくつかの小さい個別のインピーダンスを分布させることで実現され、
前記追加インピーダンスは、より大きい伝導性の材料によって、または、半導体材料を用いて実現されることを特徴とする方法。 - 前記分離距離は前記追加インピーダンスによって変化し得ることを特徴とする、請求項1に記載の方法。
- 所望の前記追加インピーダンスは、それぞれの前記過電圧アレスタにおける目標インピーダンス増加によって実現されることを特徴とする、請求項1または2に記載の方法。
