The lightning circuit breaker comprises a housing provided with a first terminal and a second terminal; an inductance module is arranged in the housing and is connected in series with a circuit breaker module; the inductance module and the circuit breaker module are connected in parallel with a lightning current discharge access module; the circuit breaker module is connected in parallel with a high-frequency inductive reactance test module; and the high-frequency inductive reactance test module is connected in series with a control circuit. The control circuit is provided with a control switch.
