Electromagnetic pulse shield assembly and enclosure for protecting electrical equipment

摘要

A shielding enclosure for blocking electromagnetic pulses to protect electrical equipment includes shield panels having a layered structure of conductive sheets and insulating sheets between the conductive sheets with an outward conductive sheet at a first end of the layered structure and an inward conductive sheet at a second end of the layered structure, and a first ground wire connected to the outward conductive sheet for connecting to a ground, and a second ground wire incorporating a rectifier and connected to the inward conductive sheet for connecting to a ground, the rectifier being oriented to restrict the electric current in the second ground wire to flowing from the inward conductive sheet to the ground; where the shield panels are positioned so that the inward conductive sheet generally faces the electrical equipment and the outward conductive sheet generally faces away from the electrical equipment.
