Large photovoltaic power station are built in wide deserts, mountains and fields, and lighting accidents occur frequently. This paper proposes a gas arc-extinguishing device to lightning protection and ensure that photovoltaic power stations can continue to generate electricity safely. The gas arc-extinguishing device principle is analyzed, and then the arc extinguishing process is simulated by COMSOL Multiphysics simulation software. Finally, the power-frequency continuous current interruption test is performed. The simulation and test results show that the device can effectively arc extinguishing on the insulator of the transmission line of large photovoltaic power station.
