Description
Technical field
The utility model relates to antenna feeder electromagnetic protection technical field, particularly relates to a kind of outdoor base tower antenna feeder electromagnetic protection system.
Background technology
Forest fire be a kind of sudden strong, there is wide, destructive large, the natural calamity of disposing difficulty of putting out a fire to save life and property, the feature that forest fire has sudden, randomness, can bring about great losses in the short time.Accomplish early discovery, early control, early avoid being of paramount importance link in forest fire prevention and control, therefore how carrying out early warning in early stage, accurately and timely warning for forest fire is problem important and in the urgent need to address in forest fire prevention and control.
And the combustible of forest belongs to solid fuel.Its combustion process is generally divided into preheating, naked light burning and charcoal burning three phases; I.e. warm-up phase: when combustible is heated, temperature rises gradually, large quantity of moisture evaporation and dry, simultaneously occur local heating decomposition, generating portion combustible gas and non-flammable gases.But due to large quantity of moisture evaporation consumption of calorie, temperature rises slowly, and oxidation rate is very slow, only occurs smoldering, can't reach burning-point.Naked light combustion phases: after combustible is smoldered, temperature rises very fast, continue decomposes, volatilize the imflammable gas such as a large amount of carbon monoxide, hydrogen and hydrocarbon, become flammable mixed gas after mixed with air, oxidation, exothermic process are accelerated, are aggravated, after reaching burning-point, fuel gas is lighted immediately, produces carbon dioxide and steam, releases a large amount of light and heat energy.And make neighbouring combustibles temperature increase, cause burning to spread.The charcoal burning stage: when timber completes after naked light burning becomes charcoal, have the burning of flame just to stop, namely proceeding to the charcoal non-flaming combustion stage.Charcoal burning belongs to the red-hot burning of solid, because burning occurs in the surface of solids, therefore is also called surface combustion.Although it does not have flame, but still a small amount of light and heat can be produced.
And be generally adopt the mode that corresponding camera collection image information is set on Ji Ta in the monitoring of existing forest fire protection, therefore, forest fire protection control point is generally all located at mountain top, and mountain top is generally thunder and lightning prone areas, simultaneously owing to installing lightning rod, more easily suffer straight thunderbolt, so the comparatively general area of lightning induction on power line is strong.And implement Multistage shielding by the anti-minefield (LPZ) that IEC divides.First the effect of shielding depends on the attenuation degree of primary shield net, next depends on shielding thickness (preferably close to electromagnetic wavelength), mesh density (the larger then degree of reliability of density is higher), shielding material (adopt high magnetic material during low frequency, during high frequency, employing copper material, aluminium are advisable); Measurement result shows, High-frequency Interference voltage can be reduced an order of magnitude, can reduce by two orders of magnitude during two-terminal-grounding during electric wire (cable) screen one end ground connection.It two is use wire establishment net shielded type cable, because it is lightweight, easy to use and be widely used.And the antenna feeder of base station is connected to steel tower top, have passed through the path of the downlead of lightning rod, because steel tower is very high, antenna feeder is very long, the most easily be subject to induction and the high-voltage impact of strong-electromagnetic field, very large threat is caused to equipment, therefore especially will carry out shielding protection work for the antenna feeder on Ji Ta.
