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

Anti-nuclear electromagnetic pulse integrated form traffic filter

Technical field

The present invention relates to a kind of anti-nuclear electromagnetic pulse traffic filter.

Background technology

At present, the consequence of the electromagnetic pulse that nuclear explosion produces will make the transmission of enemy's Command, Control, Communication And Intelligence be destroyed, cause that systemic breakdown, power network open circuit, metal pipe line and underground cable communication network etc. are influenced, make operational chain of command be absorbed in non-transformer, without communication, without computer three without the world.Its consequence is to destroy electronic equipment and harm people not, in other words nuclear weapon " has been routinized "., to the protection of operational chain of command terminal equipment, be the primary problem of pendulum in face of various countries military system of defense.

Have These characteristics just because of nuclear electromagnetic pulse, thereby communication apparatus and system have been formed serious threat.

In the middle of the measure of numerous protection nuclear electromagnetic pulses, electromagnetic shielding is to prevent main and effective method in nuclear electromagnetic pulse with adding filter method.Be applied to common anti-filter of divulging a secret the shielding machine room in the past and can not adapt to the requirement of contemporary war, on the one hand, shielding machine room filter commonly used is all generally that individual event enters, and takies wall area large; On the other hand, be development and the progress along with nuclear weapons technology, can greatly strengthen its electromagnetic pulse effect through custom-designed nuclear weapon, improve the share of electromagnetic pulse energy at whole explosion energy, results of wave erection, increase high frequency radiation, so that the excitation High-Power Microwave, the directed radiation electromagnetic energy.So, filter is not only only to have anti-function of divulging a secret, and also should have anti-nuclear electromagnetic pulse, and the protection command system is not destroyed by nuclear electromagnetic pulse and the function that works.

The problem that exists in protection works; in the commander and communication protective engineering that build in the past; people have just taked certain electromagnetic shielding safeguard procedures; but exist in the shielding computer room construction and ignored filter anti-nuclear electromagnetic pulse ability; and when a large amount of cable turnover machine rooms, filter apparatus can't be installed; and make cable directly pass shield shell, cause shielding machine room integral body to hit to EMP/T Bomb the corresponding shielding protection effect that do not have.

Summary of the invention

The purpose of this invention is to provide a kind of anti-nuclear electromagnetic pulse integrated form traffic filter, with solution, improve the existence of war communications hinge and the technical problem of information countermeasure ability.

In order to realize the foregoing invention purpose, the technical solution adopted in the present invention is as follows:

Anti-nuclear electromagnetic pulse integrated form traffic filter, this filter comprises LC filter and RV bleeder, described filter is composed in parallel by the multichannel module, in the module of Zai Mei road, the RV bleeder is that RV piezo-resistance and feedthrough capacitor compose in parallel, and be connected on the input of LC filter and output, described LC filter and RV bleeder weld and with the insulation reperfusion structure, are fixed on pcb board, according to using, the above-mentioned module of some need to be become one by the cabinet slot.

The present invention has following advantage:

(1) solved the technical barrier of the nuclear electromagnetic pulse protection that exists in the commanding and defending engineering construction of in the past building, communication and the charge Engineering Anti nuclear electromagnetic pulse striking capabilities that improves wartime played an important role.Obvious protection antagonism is arranged while in information war, electromagnetic pulse weapon being hit under the future high-tech condition, the information fighting ability that improves wartime is had important effect and realistic meaning.

(2) anti-nuclear electromagnetic pulse integrated form traffic filter, solved in commander's guard system construction in the past, and common filter does not have the anti-nuclear electromagnetic pulse ability; Traditional filter in the situation that the shielding machine room to cross the wall number of cables be more than hundred pairs, the One's name is legion of its filter, bulky, can't realize the problem that practical application is installed in commanding and defending engineering core computer room construction.Improved the ability of the anti-nuclear electromagnetic pulse of core machine room; Reduce simultaneously project cost, reduced the process Installation difficulty, simplified the engineering complexity.

Description of drawings

Fig. 1 is circuit theory diagrams of the present invention.

Fig. 2 is single-sided structure schematic diagram of the present invention.

Embodiment

Concrete structure of the present invention and execution mode accompanying drawings are as follows:

Referring to Fig. 1, this filter comprises the bleeder that LC filter (C1-4, L), piezo-resistance (RV) and electric capacity (C) form, described filter is composed in parallel by the multichannel module, in the module of Zai Mei road, the RV bleeder is feedthrough capacitor, and be connected on the input of LC filter and output, described LC filter and RV bleeder weld and with the insulation reperfusion structure, are fixed on pcb board, according to using, the above-mentioned module of some need to be become one by the cabinet slot.

Anti-nuclear electromagnetic pulse integrated form traffic filter be with tens, the even more single channel module integration in hundreds of road is integrated, thereby realize the requirement of mass communication cable turnover shielding machine room.

Anti-nuclear electromagnetic pulse integrated form traffic filter is under the 7.0-17.2kV condition at rising front less than 12ns left and right, half-breadth 700ns, crest voltage, carries out respectively the radiation of nuclear electromagnetic pulse and injects two kinds of experiments.Experiment shows, anti-nuclear electromagnetic pulse inject and radiation condition under, filter still can work; Filter has obvious inhibitory action to voltage signal, and its pad value is more than 60dB.

Referring to the described embodiments of the invention of Fig. 2.Be fixed in main box 4 by feedthrough capacitor 8, filter 7, the fastening aluminium sheet 5 of electric capacity installation, 6 channeling modules, main box 4 is fixed on shield shielding steel plate by waveguide mouth 9 and securing member 3 are installed, communications cable inlet wire 2 enters in main box 4 by incoming line 1, and communications cable place line 10 is drawn main box 4 by waveguide mouth 9 is installed.

Claims

1. anti-nuclear electromagnetic pulse integrated form traffic filter, it is characterized in that, this filter comprises LC filter and RV bleeder, described filter is composed in parallel by the multichannel module, in the module of Zai Mei road, the RV bleeder is that RV piezo-resistance and feedthrough capacitor compose in parallel, and be connected on the input of LC filter and output, described LC filter and RV bleeder weld and with the insulation reperfusion structure, are fixed on pcb board, according to using, the above-mentioned module of some need to be become one by the cabinet slot.
