Description

Technical field [0001] The invention relates to the field of lightning protection, in particular to a lightning protection device for power generation equipment and a use method. Background technique [0002] Although it has entered the high-tech era, it is still troubled by the three factors of energy, environment and safety. With the high integration of communication equipment, the systematization of communication networks, and the integration and centralization of communication equipment management, it is widely used A large number of precision electronic devices in various communication systems have reduced overvoltage and overcurrent resistance levels, and lightning disasters often occur. This has become a major public hazard in our "network age and electronic age". The intelligent system may be attacked by overvoltage when it is working. Overvoltage may invade the power supply system and signal system in the form of voltage or current waveforms and spread through its electr...
