Title:
ARC DETECTING CIRCUIT, BREAKER, POWER CONDITIONER, SOLAR PANEL, MODULE WITH SOLAR PANEL, AND CONNECTION BOX
Document Type and Number:
WIPO Patent Application WO/2019/208027
Kind Code:
A1
Abstract:
An arc detecting circuit (10) for detecting an arc generated in a transmission path (L1) is provided with: a capacitor (C1) which is disposed in a pathway (L2) that branches from the transmission path (L1) and which causes an alternating current component signal contained in a signal flowing through the transmission path (L1) to flow from the transmission path (L1) to the pathway (L2); a resistor (R1) which is connected in series with the capacitor (C1) in the pathway (L2), and which generates a voltage signal corresponding to the alternating current component signal; a filter unit (12) into which the voltage signal generated by the resistor (R1) is input, and which allows a signal having a frequency corresponding to an arc to pass; and an arc determining unit (11) which determines the generation of an arc on the basis of the signal that has passed through the filter unit (12).
