Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Referring to Fig. 1, shell 3 two ends are respectively charged into coaxial fitting 1 and coaxial fitting 5, a face of shell 3 joint 2 of packing into.Shell 3 can use mounting panel 4 fixing.
Referring to Fig. 2, Fig. 2 is an electrical schematic diagram of the present utility model.The utility model mainly is made up of radio frequency operation circuit, thunder and lightning path, direct current tie line and intermediate-freuqncy signal path.Below in conjunction with Fig. 2 the structure of the present utility model and the course of work are described.
The radio frequency operation circuit: lightning protection device is connected in the radio system, requires its influence to the radio frequency microwave transmission as far as possible little.Radio frequency operation circuit in the utility model mainly is made up of coaxial fitting 1, coaxial fitting 5, microstrip line 6, microstrip line 8, coupling capacitance 7, and radiofrequency signal is through coaxial fitting 5 inputs, from coaxial fitting 1 output.Coupling capacitance 7, microstrip line 6, microstrip line 7, inductance 9, inductance 13 constitute the microstrip line high pass filter.High pass filter places stopband with the thunder and lightning frequency spectrum, presents high decay, and microwave signal is presented extremely low decay, guarantees that the signal transmission is unaffected.10,15 pairs of radio-frequency-short of shunt capacitance make inductance 9,13 effective groundings.
The thunder and lightning path: the thunder and lightning path mainly is made up of coaxial fitting 1, inductance 9, gas discharge tube 11, decoupling element 12, decoupling element 16 and TVS pipe 17.The thunderbolt high voltage enter circuit through coaxial fitting 1, because of its frequency spectrum in the high pass filter stopband, filter reflects away the short circuit of thunder and lightning energy.9 pairs of thunder and lightning short circuits of inductance make it directly arrive gas discharge tube 11 through inductance 9, and gas discharge tube 11 discharges under the effect of thunder and lightning high pressure, and the thunder and lightning energy is released through the thunder and lightning ground wire.The thunder and lightning energy of small leakage arrives TVS pipe 17 through decoupling element 12 and 16, and the reaction time of TVS pipe 17 is exceedingly fast, and in the time lightening pulse current bypass that leaks is arrived ground at nanosecond order.By the secondary lightning protection, the thunder and lightning energy level in the lightning protection device output signal is low, can not work the mischief to protected equipment.
