Title:
PHOTOVOLTAIC GENERATION DEVICE HAVING FIRE PREVENTION FUNCTION AND BREAKDOWN DIAGNOSIS FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/043875
Kind Code:
A1
Abstract:
The present invention relates to a photovoltaic generation device having a fire prevention function and a breakdown diagnosis function. The photovoltaic generation device according to the present invention comprises: a photovoltaic battery module having a photovoltaic battery string in which a plurality of photovoltaic battery cells are connected in series; and a junction box including a current blocking unit connected in parallel to the photovoltaic battery string, wherein the current blocking unit comprises: a bypass diode having one end connected to one end of the photovoltaic battery string; a thermal fuse connected between the other end of the bypass diode and the other end of the photovoltaic battery string; a first LED connected in parallel to the thermal fuse and turned ON or OFF according to the driving state of the thermal fuse; and a second LED connected in parallel to the bypass diode and turned ON or OFF according to the driving state of the bypass diode. In the present invention, when a breakdown occurs in the bypass diode of the photovoltaic battery module, the occurrence of a fire in the photovoltaic battery module because of an increase in the temperature of the bypass diode can be prevented. Whether a breakdown occurs in the thermal fuse and the bypass diode can be visually confirmed, and thus a loss in power generation due to the breakdown can be prevented.
