The invention provides a physical signal isolation prevention device for mobile field electronic equipment. It includes a metal oxide magnetic ring, a primary reactance coil and a secondary reactance coil connected to the metal oxide magnetic ring, the primary reactance coil includes an input port, the input port receives the input of lightning and electromagnetic pulse signals, the secondary The stage reactance coil includes an output port, which outputs the signal processed by the physical signal isolation and protection device; the physical signal isolation and protection device is used to perform physical Joule energy isolation processing on the received lightning and electromagnetic pulse signals. The device of the invention has high resistance to lightning current energy, is very suitable for places with harsh geological conditions such as mountainous areas, waterside, Gobi, grassland and other areas with high lightning incidence, and is an ideal protection device for mobile field system equipment. |
