Abstract: A lightning protection apparatus disposed in a photovoltaic power generation system includes first lightning protection units in a one-to-one correspondence with phase lines at a to-be-protected location in the photovoltaic power generation system and a second lightning protection unit connected in series to the first lightning protection units. A first terminal of each first lightning protection unit is connected to a corresponding to-be-protected phase line, and a second terminal of each first lightning protection unit is connected to a first terminal of the second lightning protection unit. A second terminal of the second lightning protection unit is connected to an earth wire. The second lightning protection unit includes at least one gas discharge tube.
