(FR) DISPOSITIF DE MESURE DU COURANT DE FOUDRE
(DE) BLITZSTROMMESSVORRICHTUNG
Abstract:
(EN) Lightning current measuring apparatus for a lightning protection system of a wind power system, having a sensor arrangement (18) which is arranged at a distance from a lightning conductor (13) and can be used to capture properties of a magnetic field (B) generated by a lightning current (I) flowing through the lightning conductor (13), and having an evaluation device (25) which is connected to the sensor arrangement (18) and can be used to determine or ascertain the lightning current (I) flowing through the lightning conductor (13) by evaluating the captured properties of the magnetic field (B), wherein the sensor arrangement (18) has one or more inductive sensors (26, 27), which can be used to capture a temporal change in the magnetic field (B), and one or more magnetic field sensors (28, 29) which can be used to capture a variable characterizing the strength of the magnetic field (B).
(FR) L'invention concerne un dispositif de mesure du courant de foudre pour un système de protection contre la foudre d'un aérogénérateur, comprenant un arrangement capteur (18) disposé à une certaine distance d'un paratonnerre (13), au moyen duquel peuvent être détectées les propriétés d'un champ magnétique (B) générée par un courant de foudre (I) qui s'écoule à travers le paratonnerre (13), et un appareil d'interprétation (25) relié à l'arrangement capteur (18), au moyen duquel peut être défini ou déterminé me courant de foudre (I) qui s'écoule à travers le paratonnerre (13) en interprétant les propriétés détectées du champ magnétique (B). L'arrangement capteur (18) possède un ou plusieurs capteurs inductifs (26, 27), à l'aide duquel ou desquels peut être détectée une variation dans le temps du champ magnétique (B), et un ou plusieurs capteurs de champ magnétique (28, 29), à l'aide duquel ou desquels peut être détectée une grandeur qui caractérise l'intensité du champ magnétique (B).
(DE) Blitzstrommessvorrichtung für eine Blitzschutzanlage einer Windkraftanlage, mit einer im Abstand zu einem Blitzableiter (13) angeordneten Sensoranordnung (18), mittels welcher Eigenschaften eines von einem durch den Blitzableiter (13) fließenden Blitzstrom (I) erzeugten Magnetfelds (B) erfassbar sind, und einer mit der Sensoranordnung (18) verbundenen Auswerteeinrichtung (25), mittels welcher unter Auswertung der erfassten Eigenschaften des Magnetfelds (B) der durch den Blitzableiter (13) fließende Blitzstrom (I) bestimmbar oder ermittelbar ist, wobei die Sensoranordnung (18) einen oder mehrere induktive Sensoren (26, 27), mittels welchem oder welchen eine zeitliche Änderung des Magnetfelds (B) erfassbar ist, und einen oder mehrere Magnetfeldsensoren (28, 29) aufweist, mittels welchem oder welchen eine die Stärke des Magnetfelds (B) charakterisierende Größe erfassbar ist.
