Title (EN) ARC DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION D’ARC
(JA) アーク検出装置
Abstract:
(EN) The present invention detects an electrical arc in a solar power generation system provided to a booster circuit. An arc detection device (61) is provided with a capacitor (19) for forming a bypass electric current path (23) for bypassing a booster box (22) of a solar power generation system (1) having a solar cell string (11a), an electric current sensor (31a) for measuring an electric current flowing through the capacitor (19), and a first arc determination unit for determining whether arcing is present on the basis of a high-frequency component of the electric current measured by the electric current sensor (31a).
(FR) La présente invention détecte un arc électrique dans un système de génération d’énergie solaire disposé sur un circuit d’amplificateur. Un dispositif de détection d'arc (61) est pourvu d'un condensateur (19) pour former un trajet de courant électrique de dérivation (23) pour contourner un boîtier d'amplification (22) d'un système de génération d'énergie solaire (1) comportant une chaîne de cellules solaires (11a), un capteur de courant électrique (31a) pour mesurer un courant électrique circulant à travers le condensateur (19), et une première unité de détermination d'arc pour déterminer si un arc est présent sur la base d'une composante à haute fréquence du courant électrique mesuré par le capteur de courant électrique (31a).
(JA) 昇圧回路が備える太陽光発電システムの電気アークを検出する。アーク検出装置(61)は、太陽電池ストリング(11a)を有する太陽光発電システム(1)の昇圧箱(22)を迂回するバイパス電流経路(23)を形成するコンデンサ(19)、コンデンサ(19)を流れる電流を計測する電流センサ(31a)、および電流センサ(31a)が計測する電流の高周波成分に基づきアークの有無を判定する第1アーク判定部を備える。
