Description
Technical field
The utility model has related to a kind of lightning protection system of radio communication base station, has related in particular to the isolated intelligent lightning protection system of a kind of radio communication base station.
Background technology
The earth connection of network, communications equipment room, mainly comprise lightning proof ground, protect three kinds, ground, place of working by Function Classification at present, is divided into doughtily (lightning protection, earth mat), weak ground (protecting ground, place of working) two classes by characteristic.Lightning protection (also referred to as lightning protection device or surge protector): the device that refers to provide for power circuit, the signal line of equipment or system the by-pass shunt passage; thunder and lightning overvoltage in circuit is shunted over the ground, shifted, and its cable that connects over the ground is on the lightning protection line.Protection ground (also claim casing ground): thereby avoid AC and DC power supply line to encounter casing, equipment and the person are constituted a threat to, uncharged metal chassis is connected to the ground, and when occuring to leak electricity or casing when charged, ensures personal safety.Place of working: the ground of the reference potential reference that provides for the operation of electric power, electronic equipment.
Two classes ground in ideal should be separate, do not interfere with each other, or each own independently ground network, and the equipment on especially weak ground can not be subject to strong earthy impact, otherwise has the danger of high pressure counterattack.But now earthing mode adopts the joint grounding system, is about to all earth connections (place of working, protection ground, lightning proof ground) and is connected on a bus-bar, is connected with earth mat by downlead.Existing earthing mode has following defective and deficiency:
When 1, building earth mat, early investment and maintenance cost are high.Distich is closed grounding resistance requirement integrated communication building less than 1 Ω according to YD5098-2005 " communication bureau's (station) lightning protection and grounding engineering design standard ", and the mobile communication base station is less than 10 Ω.For the normal operation of equipment and lightning protection requirement, earth resistance is less, lightning protection effect is better, in order to realize that small connect ground resistance forms ground network, the a large amount of chemical products such as copper material, steel, resistance reducing agent and earth rod of normal employing improve P in soil H value and reduce earth resistance, unavoidably there is couple corrosion in its metal structure, thereby has accelerated the corrosion rate of earth electrode, and useful life is short and need a large amount of human and material resources of cost, financial resources to drop into.
2, build the ground network construction difficult, measure difficult, Maintenance Difficulty and rectification difficult.Construction is difficult: (as station, city, stone mountain, Gobi desert, desert etc.) difficulty is carried out earth mat construction, materials handling, operation etc. in the base station of high earthing resistivity.It is difficult to measure: the restriction of method of measurement and environmental factor can not reach the low-resistance value of real " standard-required ".Maintenance Difficulty: because needs are buried a large amount of metal materials underground, increased antitheft work and difficulty.Rectification is difficult: the factors such as earth mat climate, material oxidation, resistance-lowering material loss, and earth resistance can increase gradually, need to carry out the secondary rectification, and difficulty and input are not second to the early investment cost.
3, influence each other between grounding system, grounding apparatus.Owing to all carrying out joint grounding by the concurrent of same bus-bar, the mode of common network with the ground wire that connects weakly doughtily; even therefore earth resistance reaches standard; both influencing each other is also very large, will mutually conduct, disturbs, cause the counterattack of earth potential high pressure and high pressure conduction along weak ground wire (protective earthing line, working earthing line) when especially lightning surge voltage enters union ground grid by lightning protection.
4, electrical theory basis science not.The interference value of the earth potential reality of joint grounding system is that (KV level) and communication network device EMC value are not the same orders of magnitude for (V level), the requirement of adopting the method that reduce earth resistance can not reach communication work ground connection EMC theoretical according to Ohm's law, (should be m Ω magnitude rather than Ω magnitude by this theoretical earth resistance).
5, the coupling between multistage lightning protection device needs cable distance to realize, and residual voltage is high, weak effect.Existing shocking preventing technology adopts plural parallel stage formula shunt method, namely plural parallel stage is installed lightning protection device or lightning protection box (also needing in each lightning protection device prime the lightning protection device back-up breaker of connecting equally) between power circuit center line and ground, be three grades of lightning protection according to standard, cable mounting distance between every grade is more than 10 meters, guarantee that lightning protection device moves successively, release step by step, if be applied in mobile base station room, communications equipment room etc. independently (this type of machine room gross area is between 10-20 square) during the small size machine room, therefore be difficult to realize every grade of cable mounting distance more than 10 meters.The purpose of the method is in order to ensure the inherently safe of lightning protection device, and lightning current enters to trespass greatly, and residual voltage is higher, lightning protection effect is poorer.
6, canonical parameter is covered actual parameter.According to the basic principle of the lightning protection lightning current of namely will releasing, reduce again residual voltage and more low better.detect when the nominal discharge current according to the residual voltage of present standard lightning protection device, and maximum discharge current is 2-2.5 times of nominal discharge current, such as nominal discharge current is 50KA, maximum discharge current is at least 100KA so, residual voltage is the residual voltage of measuring when the 50KA discharging current, and the mark or detect not just of the residual voltage during to 100KA, the data of maximum residual voltage have been covered, because the residual voltage when the test maximum discharge current should be 2 times of nominal discharge current, and residual voltage at this moment often exceeds the maximum withstand voltage of equipment, cause damage of equipment.These are all the problems that the data when experiment draw; in actual applications due to residual voltage and lightning protection device connecting line length (standard-required lightning protection device two ends connection cable must be less than 1.5 meters; but can't satisfy in actual installation is used at all), the distance of lightning protection device and protected equipment is (more near better; residual voltage is lower), the factors such as the cooperation between lightning protection device, lightning protection device earth resistance all can cause residual voltage to raise; lightning protection just having occurred has moved; but residual voltage is very high; still there is no effect, equipment still damages.
7, lightning protection box (device) is " black bear ", without active alarm or fault prompting function.The operating state of lightning protection device mostly is local indication at present, needs the attendant to estimate at the scene, detect, and just can pinpoint the problems.But at thunder and lightning remote mountain areas or unattended mobile base station, machine room frequently, lightning protection device has become undoubtedly that " black bear " be transferred to control centre without abnormal alarm or fault alarm information, and the thunder resisting equipment ruuning situation that each base station, machine room are not known by control centre yet how; Don't you know that also lightning protection device lost efficacy? the tripping operation when suffering the first wave thunderbolt of lightning protection device reserve air switch? don't you also know to have suffered the how many times thunderbolt? when suffered thunderbolt? suffered great thunderbolt? etc. important thunder and lightning invasion information.Maintenance company is in order to understand thunder resisting equipment ruuning situation at present, patrol and examine by regular or irregular artificial mode, minimum requirements is to make a call to a thunder to patrol and examine once, mostly base station, machine room tens kilometers of more than ten kilometer far away persons of person close to the control centre are far away, tens meters of the low persons of high-altitude station height above sea level, km on high person's hundreds of rice, maintenance difficulties and inspection operating efficiency are well imagined.Caused the difficult discovery of fault, difficult control, the difficult situation of safeguarding, maintenance cost remains high and the poor result of protection effect.
8, the difficult realization and meeting grown place current potential high pressure counterattack of machine room low resistance earthing system, thus introduce and damage calculator room equipment.
