Title:
ABNORMALITY DETECTING DEVICE FOR SOLAR BATTERY PANEL
Document Type and Number:
Japanese Patent JP3308434
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an abnormality detecting device that can detect the no current-conduction state of a solar battery panel easily and rapidly.
SOLUTION: This device 11 is provided with current sensors 3A-3D fitted to output cables 2A for connecting a solar battery panel 41 to indoor electric equipment, so as to detect whether a current is flowing to each output cable 2A, and an abnormality informing means 5 for informing the no current- conduction state of output cables 2A, 2B on the basis of signals sent from the current sensors 3A-3D. In the failure state of the solar battery panel 41, the current does not flow to the output cables 2A, so that this is detected by the current sensors 3A-3D, and the no current-conduction state of the output cables 2A, 2B is informed by the abnormality informing means 5.
