Abstract
The utility model belongs to the field of lightning protection design and provides a lightning protection system. The lightning protection system comprises a surge protection unit, a switching unit, a first electromagnetic induction unit and a switchover control unit. According to the lightning protection system, the switching unit is arranged on a power supply line of protected load equipment; when the first electromagnetic induction unit detects that a lightning current appears in the power supply line, the switchover control unit controls the switching unit to act so as to switch off a power supply closed circuit of the protected load equipment; and after the power supply closed circuit is switched off, the lightning current flows into a ground grid through the surge protection unit and then escapes into the underground. As the transmission channel of the lightning current to the protected load equipment is completely switched off, the probability that the protected load equipment is subjected to lightning stroke is greatly reduced, and the lightning protection effect is optimized. The lightning current is not distributed depending on the ratio of the resistance of the ground grid to the characteristic impedance of the protected load equipment any more, the requirement on the resistance size of the ground grid is lowered, and the construction cost and construction period of the ground grid are reduced.
