[0064] In this embodiment, the high-energy transient discharge unit includes a fusible fuse that can be disconnected in time in the event of a continuous short circuit. The input end of the control module 400 is connected to one end of the receiving end of the optocoupler U16. When the lightning pulse energy is less than the processing capacity of the high-energy transient discharge unit, the fusible fuse does not blow, the output voltage of the high-energy transient discharge unit is normal, the receiving end of the optocoupler U16 is turned on, and the input end of the control module 400 receives a low level, indicating that the lightning electromagnetic pulse protection module 100 is working normally; when the lightning pulse energy is greater than the processing capacity of the high-energy transient discharge unit, the fusible fuse blows, the output voltage of the high-energy transient discharge unit is 0, and the input end of the control module 400 receives a high level, indicating that the lightning electromagnetic pulse protection module 100 is working abnormally.
