An alternating current power link electromagnetic pulse mitigation device

Abstract

The utility model provides a kind of alternating current power link electromagnetic pulse suppression device, comprising: varistor, for bearing high voltage pulse and preliminary limiting pulse current;Through-capacitor, coupled to varistor for further inhibiting high-frequency electromagnetic pulse;TVS tube, coupled to varistor and through-capacitor for final limiting amplitude to the residual pulse after filtering;The varistor, through-capacitor and TVS tube are all connected on the fire line and zero line of alternating current power, and the leakage current of alternating current filter can be guaranteed not more than 25mA by varistor, while cooperating through-capacitor and TVS tube can realize multistage limiting amplitude, and then realize effectively inhibiting electromagnetic pulse in alternating current power link.
