Description
Technical field
The present invention relates to the lightning protection of mobile communicational vehicle, be specifically related to a kind of mobile communicational vehicle car load lightning-protection system.
Background technology
All based on command communication vehicle in military affairs with natural calamity emergency commading system, from the angle of lightning protection, as long as large building (comprising Earth Surface) on the ground has the possibility of being struck by lightning, and mobile communicational vehicle is often arranged near building or in the area of spaciousness, also easily become the main target of thunderbolt.If when mobile communicational vehicle stops work near building; occur when there being direct thunder and hitting building; usually can produce the phenomenons (LEMP produced during thunderbolt) such as luminous energy (lightning), acoustic energy (thunder), heat energy (thermal effect produced when conductor is hit in thunderbolt) and electromagnetic induction, what wherein have the greatest impact to surrounding devices is the electromagnetic induction phenomenon that electromagnetic pulse causes.
If when mobile communicational vehicle is directly parked in spacious field without any other building protection; at this moment mobile communicational vehicle is equivalent to the communication base station fixed; suffer thunder-strike phenomenon can be equal to communication base station to consider, namely communication base station (mobile communicational vehicle) may suffer the multiple harm such as direct thunder, induced lightening, mine transmitting device and earth potential counterattack.And portable position environment is not controlled (namely likely in mountain area, desert etc.), therefore the direct lightning strike the protection implement in portable position is very difficult.
Existing mobile communicational vehicle lightning protection comparatively simple (see figure), and protect mainly for the communication vehicle antenna in about 5 meters of height, general commercial communication vehicle can only be met but cannot meet for special car.
Existing communication vehicle lightning protection mode and drawback:
1, direct lightning strike protection: install lightning rod additional in upper antenna end and do the protection of direct thunder, but be highly generally about 5 meters, the portable antenna as being aimed at 19 meters or requirements at the higher level erection just cannot be protected at all;
2, induced lightening protection: install corresponding power source surge protector and signal Surge Protector additional to signal input port place at each power supply.But at present the mutual coupling between Surge Protector is usually done badly, be mainly manifested in following some:
2.1, a lot of producer in order to interests can be all that customer selecting leads to Surge Protector greatly, but the through-current capacity of Surge Protector is not be the bigger the better, output residual voltage for Surge Protector while through-current capacity increases will obviously increase, and not have effective protective effect on the contrary for precision equipment;
2.2, the phase mutual edge distance coupling between Surge Protector, how much suitable the matching distance namely between one-level lightning protection and secondary lightning protection or three grades of lightning protection is, the need of doing the problems such as multistage protection;
2.3, whether the environment for use of Surge Protector is selected correct, as indoor type Surge Protector and be not suitable for field and use, but most producer fails to accomplish this point;
2.4, whether Surge Protector product adaptation power itself meets device requirement, now very large hidden danger will be had as equipment power output is greater than Surge Protector load power, namely cause Surge Protector directly to damage due to the powerful output of equipment when equipment normally works, and likely cause burning of equipment;
2.5, Surge Protector New technical use and exploitation, a lot of producer is due to self-technique strength or management philosophy problem (namely earning counts out money just withdraws from the market), be unwilling to drop into too many expense in product technology research and development, cause product technology to fall behind and now need proterctive equipment not mate or cannot play a protective role at all;
3, lightning protection earthing system: the existing conventional earthing material used adopts 1-3 root Zinc-coated angle steel or round steel to do earth electrode usually, but the non-constant of resistance reducing effect, about 20 Ω are generally reached in the better place of soil resistivity, generally can only reach about 80 Ω or higher in the place that soil resistivity is higher, this type of grounding resistance all can not reach the requirement of lightning protection earthing system.
Lightning protection resistance value size is directly connected to device security problem, because the magnitude relationship of grounding resistance flows into the problem of ground release speed to thunder and lightning.The earth mat reaching standard-required or earth electrode enough large to earthing material and the earth contact area itself has good conductivity relevant (more effective than carbon steel grounding material a lot of times of the red copper grounding material as same volume); Simultaneously when lightning rod or surge protection must be connect terrain to release when releasing lightning current; as resistance value will cause too greatly lightning current to be released not in time and the physical property usefulness that big current brings can cause badly damaged to personnel or equipment, and equipment to meet with the possibility of earth potential counterattack larger.
To sum up, existing technical scheme lightning protection effect difference cannot meet the lightning protection requirement of communication vehicle, and the integrated protection against lightning being therefore directed to mobile communicational vehicle needs further perfect.
