Abstract

A short-wave radio station high-altitude nuclear electromagnetic pulse protection device belongs to the technical field of electromagnetic pulse protection, and the invention particularly relates to a short-wave radio station high-altitude nuclear electromagnetic pulse protection device. The invention provides a short-wave radio station high-altitude nuclear electromagnetic pulse protection device with good protective effect on strong electromagnetic pulse. The short-wave radio station high-altitude nuclear electromagnetic pulse protection device comprises a gas discharge tube GDT1. The short-wave radio station high-altitude nuclear electromagnetic pulse protection device has the structural features that one end of the GDT1 is respectively connected with one end of an antenna and one end of a resistor R5, the other end of the GDT1 is grounded, and the other end of the R5 is respectively connected with one end of a gas discharge tube GDT2, a toggle terminal of a controlled end of a relay, and one end of a capacitor C1; the other end of the GDT2 is connected with one end of a first voltage dependent resistor, the other end of the first voltage dependent resistor is connected with one end of a second voltage dependent resistor, the other end of the second voltage dependent resistor is connected with one end of a third voltage dependent resistor, and the other end of the third voltage dependent resistor is grounded.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic pulse protection, in particular to a high-altitude nuclear electromagnetic pulse protection device for short-wave radio stations. Background technique [0002] Strong electromagnetic pulses will form surge currents in short-wave, ultra-short-wave and communication equipment. The rising edge time is about nanoseconds, the pulse duration can reach hundreds of nanoseconds, and the radiation field strength can reach hundreds of kilovolts / meter , the existing lightning protection facilities cannot achieve such a response speed, causing huge damage to the equipment, especially through the antenna coupling into the receiver is the most harmful. [0003] Because the high-altitude nuclear electromagnetic pulse (HEMP) environment has more serious effects on short-wave radio stations than conventional electronic countermeasures, and even causes permanent damage to equipment, this puts forward higher ...
