Integrated nuclear electromagnetic pulse resistant signal filter

Abstract

The invention discloses an integrated nuclear electromagnetic pulse resistant signal filter. The filter comprises LC filter bodies and RV bleeders. The filter is composed of a plurality of modules by parallel connection. In each module, each RV bleeder is composed of an RV varistor and a feedthru capacitor by parallel connection and connected to output and input ends of the LC filter bodies, the LC filter bodies and the RV bleeders are welded and fixed on a printed circuit board (PCB) by an insulation pouring structure, and a certain amount of the modules are integrated through a case slot as required. Survival and information countermeasure capacities of communication centers during wartime can be improved through the integrated nuclear electromagnetic pulse resistant signal filter.

Description

technical field [0001] The invention relates to an anti-nuclear electromagnetic pulse signal filter. Background technique [0002] At present, the consequences of the electromagnetic pulse generated by the nuclear explosion will destroy the enemy's command, control, communication and intelligence transmission, lead to system paralysis, power grid disconnection, metal pipelines and underground cable communication networks, etc. A world without power, communication, and computer. Its effect is to destroy electronic equipment without harming people, which is to say, to "routineize" nuclear weapons. The protection of the terminal equipment of the combat command system is the primary issue facing the military defense systems of various countries. [0003] It is precisely because the nuclear electromagnetic pulse has the above characteristics that it poses a serious threat to communication equipment and systems. [0004] Among the many measures to protect against nuclear electr...

Problems solved by technology

[0005] The problems existing in the protection project, in the command and communication protection projects constructed in the past, people only took certain electromagnetic shielding protection measures, but there were some problems in the construction of the shielding machine room that the anti-nuclear electromagnetic pulse ability of the filter was ignored, and in a large number of cables Filtering equipment cannot be installed when entering and exiting the computer room, so that the cables directly pass through the shielding shell, so that the shielding computer room as a whole cannot provide corresponding shielding protection against electromagnetic pulse bombs
