Method for simultaneously preventing strong nuclear electromagnetism and thunder and lightning from influencing communication signals

A method for simultaneously preventing strong nuclear electromagnetism and thunder and lightning from affecting communication signals comprises the steps that a nuclear electromagnetic pulse protection module is connected in series in front of a thunder and lightning electromagnetic pulse protection module at a communication signal input end; the method comprises the following steps: firstly, suppressing a nuclear electromagnetic pulse through a nuclear electromagnetic pulse protection module, so that the residue of the nuclear electromagnetic pulse output by the output end of the nuclear electromagnetic pulse protection module suppressed by the nuclear electromagnetic pulse protection module is less than 1A; and lightning electromagnetic pulses are absorbed and protected through the lightning electromagnetic pulse protection module, so that the influence of strong nuclear electromagnetism and lightning on communication signals is eliminated, and the communication equipment is ensured to work safely in the tw
