Description

The lightning protection structure with thunder and lightning electric shock equipotential propagation function on Ji Ta

Technical field

The utility model relates to base tower shocking preventing technology field, and the thunder and lightning that has relating in particular on a kind of Ji Ta shocks by electricityThe lightning protection structure of equipotential propagation function.

Background technology

Forest fire be a kind of sudden strong, occur wide, destructive large, dispose the difficult natural calamity of putting out a fire to save life and propertyEvil, that forest fire has is sudden, randomness, the feature that can bring about great losses in the short time. Accomplish earlyFinding, early controlling, early avoiding is of paramount importance link in forest fire prevention and control, therefore how for forest fireCarrying out early warning in early stage, accurately and timely reporting to the police 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 be generally divided into the burning of preheating, naked light andCharcoal burning three phases; Be warm-up phase: when combustible is heated, temperature rises gradually, large quantity of moisture steamsSend out and be dried, local heating occurs simultaneously and decompose, generating portion combustible gas and non-flammable gases. But byIn large quantity of moisture evaporation consumption of calorie, temperature rise is slow, and oxidation rate is very slow, only occurs smoldering, also notCan reach burning-point. Naked light combustion phases: after combustible is smoldered, temperature rise is very fast, continues decomposes,Volatilize the imflammable gas such as a large amount of carbon monoxide, hydrogen and hydrocarbon, after mixing with air, becomeFlammable mixed gas, oxidation, exothermic process accelerate, aggravation, when reaching after burning-point, fuel gas immediately byLight, produce carbon dioxide and steam, emit a large amount of light and heat energy. And make near combustible temperatureRise, cause that burning spreads. The charcoal burning stage: become after charcoal when timber completes naked light burning, have fireThe burning of flame just stops, and proceeds 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 be called again surface combustion. Although it does not have flame, but still can produce fewThe light and heat of amount.

And be generally to adopt corresponding camera collection figure is set on Ji Ta in the monitoring of existing forest fire protectionThe mode of picture information, therefore, forest fire protection control point is generally all located at mountain top, and it is multiple that mountain top is generally thunder and lightningArea due to lightning rod being installed, more easily suffers straight thunderbolt, so the lightning induction on power line simultaneouslyGeneral area is strong. Therefore require power-supply system lightning protection product have high throughflow capacity, high response speed,There is the requirements such as good fire resistance, moreover its shaft tower or Ji Ta adopt the steel tower of 15 meters or 18 meters to make,Therefore in application, its Ji Ta is very easily struck by lightning, and if the lightning protection measures of Ji Ta is not in place, be easy to Yin JiBreaking out of fire phenomenon after tower is struck by lightning, causes Ji Ta to become the fuse cord of fire, and this is in whole forest fire protectionIn system, should not occur, also should avoid occurring.

And in IEC standard, point out that it is a part for internal lighting protection measure that equipotential connection connects, its object is to subtractFew caused potential difference of lightning current; And equipotential is with connecting wire or overvoltage (surge) protector, willBe in lightning protection device in the space that needs lightning protection and building metal frame, metal device, external wire,Electric device, telecommunication installation etc. couple together, and form equipotential and connect network, to realize all the electricity such as pressurePosition. Just investigate and find at present, nearly all wireless base station adopts and shares earth mat, connects sudden strain of a muscle thunderstorm hour at lightning rodThere will be following thunder calamity hidden danger: 1. the earthy fluctuation meeting that shares earth mat is communicated by letter to AC and DC consumerInterface causes interference; Can not for communication and control appliance cleaner signal place of working is provided; 3. adopt altogetherWith the base station of earthed system, may make earth potential increase because lightning rod, lighting proof strip suffer thunderbolt, make and ground simultaneouslyNet connected place of working current potential and rise, and occur transient overvoltage between itself and signal transmssion line, power line;Therefore, must strengthen the equipotential dynamics in base station; Therefore, the lightning-arrest and ground connection of headend equipment shaft tower or Ji TaDirectly affect the safety and reliability of whole system, will bring huge once ignore to take shelter from the thunder with ground connectionLoss. Therefore, further improving the lightning ability of Ji Ta self, is to realize the base that forest fire monitorsOne of this measure.
