Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the structural representation of the utility model examination mobile base station lightning-protection system, described mobile base station lightning-protection system comprises associating earth mat 10, be arranged on the indoor grounding bar 21 (can be called for short indoor row) and the outdoor grounding bar 22 (can be called for short outdoor interior row) of machine room, described indoor grounding bar 21 and outdoor grounding bar 22 respectively by indoor row draw reach the standard grade 23 and outdoor row draw to reach the standard grade and 24 draw from described associating earth mat 10 and to connect, power line 32 (referring to Fig. 5) or the optical cable 34 (referring to Fig. 6) introduced outside described machine room carry out buried before entering machine room, the feeder line of introducing outside described machine room 36 carries out multipoint earthing, A.C. distribution box 42 and Switching Power Supply cabinet 44 in the described machine room are provided with lightning protection device, the reinforcement of comprehensive cabinet 46 is connected with described outdoor row 22 in the described machine room, and the non-live metal body in the described machine room is connected with described indoor grounding bar 21.
Fig. 2-Figure 10 describes the lightning protection structure of described mobile base station lightning-protection system various piece respectively below.
As shown in Figure 2, described associating earth mat 10 can comprise transformer earth mat 12, machine room earth mat 14 and base station iron tower earth mat 16, and described transformer earth mat 12, machine room earth mat 14 can be communicated with formation associating earth mat by lead 18 welding with base station iron tower earth mat 16.Because the earth mat associating both can increase lightning current discharge area over the ground, can avoid again introducing the sparking of equipment appearance potential difference arcing on the same stage because of different ground wires.
As shown in Figure 3 and Figure 4, the 21 main effects of described indoor grounding bar are to provide place of working and protection ground to equipment, must be clean " ", the part lightning current of also can releasing simultaneously; Described outdoor grounding bar 22 main effects are the induction lightening stream of releasing.Connect so indoor row 21 and outdoor row 22 separate to draw on the net from ground, and they draw contact on the net on ground distance should be not less than 5 meters.By empirical discovery, if lightning current in soil by 5 meters release over the ground, will decay more than 95%, the induction lightening stream on the outdoor like this row 22 just can normally not move by the equipment that seriously interferes with by the decay of releasing over the ground of earth mat.Described indoor grounding bar 21 of present embodiment and outdoor grounding bar 22 respectively by indoor row draw reach the standard grade 23 and outdoor row draw to reach the standard grade and 24 draw from described associating earth mat 10 and to connect, concrete, described indoor row draws to reach the standard grade and 23 draws with described outdoor row and to reach the standard grade 24 by being connected with earth mat with horizontal grounding body 25 ways of connecting, outdoor like this row's last 22 induction lightening stream just can not flow to indoor row 21, thereby the induction lightening that can avoid outdoor row last 22 flows to into indoor row 21 and then arrival equipment, the operation of jamming equipment, and then equipment occurs and hang phenomenon, perhaps cause the short circuit of insulation breakdown power frequency continued flow, damage the problem of burning apparatus.
In addition, because indoor row draws to reach the standard grade and 23 draws to reach the standard grade with outdoor row and 24 may have different potential differences, as adopt Hot-dip zinc-coated flat steel sheet to do to draw and reach the standard grade, and each interval is near excessively, potential difference may be produced between them and the arcing sparking, 20cm should be not less than so two Hot-dip zinc-coated flat steel sheets draw the aerial spacing of reaching the standard grade.
As shown in Figure 5, be that example describes with the power line, for the overhead power transmission line cable, can adopt armoured cable, or adopt jacketed cable to wear the buried machine room that enters of mode of steel pipe 33, buried length is not less than 50M.Do not have ground connection for armour or steel pipe, far-end is ground connection nearby, be connected on the outdoor row 22 near the end in machine room or the inlet chamber., power line should be changed from other place and detour from iron tower angle process for overhead power transmission line, avoid the iron tower angle.For the non-constant of buried geographical execution conditions place, can before exchanging case, install the lightning protection box of the big through-current capacity of 100KA additional.
As shown in Figure 6, described feeder line 36 lays along iron tower from top to bottom from antenna 100, the described feeder line 36 of present embodiment lays along the iron tower middle part, described feeder line 36 and described antenna 100 junctions 361 and described feeder line 36 leave iron tower place 362 and are connected with iron tower by copper cash and carry out ground connection processing, and the present embodiment copper cash adopts sectional area to be not less than the multiply copper of 10mm2.So feeder line 36 can all be released before lightning current arrives BTS by the multipoint earthing weakening lightning current of can releasing step by step.
As run into the high-altitude station of inclement condition, after multipoint earthing is released, arrive the intensity of the lightning current of BTS; when still being enough to damage equipment; feeder line lightning arrester 363 (as shown in Figure 7) can be installed in machine room, and the earth connection of described feeder line lightning arrester 363 draws and is connected to outdoor row 22, with further protection equipment.In addition, described outdoor cabling rack 38 two-terminal-groundings, the machine room porch is drawn separately and is connected to earth mat.
As shown in Figure 8, pressure sensitive lightning-protection module 422, assemblage gap type lightning-protection module 424 between zero line N and the ground wire are installed between live wire L in A.C. distribution box 42 and the zero line N.The lightning-protection module type of why using between live wire L and zero line N, zero line N and ground wire is different, this is because the lightning current of wearing on three live wires and the zero line, all to release over the ground by the module between zero line and the ground wire, this just requires the ability to bear of this module strong especially, so use the big clearance type lightning-protection module 424 of through-current capacity between zero line and ground wire.
Under normal line voltage, lightning-protection module (for example quick type lightning-protection module 422 and clearance type lightning-protection module 424) is high-impedance state, is equivalent to insulation, and civil power can't form the loop by lightning-protection module.When lightning surge arrived, lightning-protection module started immediately, and sudden change of resistivity is a low resistance state, and equipment short circuit shielding that will be in parallel with it is only released lightning current over the ground by lightning-protection module, avoid the equipment sustain damage.The lightning-protection module mounting means of Switching Power Supply cabinet 44 is not given unnecessary details at this with to banish electronic box 42 similar.
As shown in Figure 9, described comprehensive cabinet 46 makes lightning current arrive earth mat by outdoor row 33 and releases over the ground by its reinforcement 462 being received outdoor row's 22 mode.Except reinforcement 462 needs the ground connection processing, also have place of working, the protection ground of optical transceiver in the described comprehensive cabinet 46, and the protection of equipment casing ground, all need the ground connection processing, can receive indoor row 21.
In addition, because transmission line is easy to the overvoltage that gone out by the magnetic field induction that indoor other leads produce, and connected optical transceiver poor anti jamming capability, the overvoltage that is transmitted sometimes on the line is routed, so optical transceiver interface that can team emphasis base station installs lightning-protection module additional.
Be prone to high potential on the reinforcement 462, belong to dangerous matter sources, so that it is exposed to airborne part is few more safe more.So when construction, reduce the exposed length of reinforcement 462 as far as possible, for example, reinforcement 462 exposed length are no more than each 5mm of its grounding nut both sides.Simultaneously, fully release rapidly over the ground for guaranteeing lightning current, the earth connection of reinforcement 462 can use sectional area to be not less than the multiply copper conductor of 16mm2.
As shown in figure 10, described non-live metal body 48 comprises accumulator stand 482, indoor cabling rack 484 and equipment casing 486, accumulator stand 482 is shaped as annular, can in the thunder and lightning magnetic field of alternation, induce high electromotive force, shape is given birth to high potential difference between support body and storage battery, produce arcing discharge breakdown storage battery, cause that battery liquid leaks outside and on fire, so accumulator stand 482 must ground connection; Indoor cabling rack 484 is a metallic object, may perhaps induce electromotive force in the electromagnetic field that indoor conductor produces, and high potential occur because of the wire insulation breakage, for the sake of security, must carry out ground connection processing.If the charged position of adjacent chute institute is different, be in contact with one another insufficiently each other again, will form sparking between them, so use lead adjacent chute is carried out cross-over connection, make their charged positions of institute equal.And indoor each equipment casing 486, for example static may appear in BTS casing among Figure 10, or because of leakage current appears in insulation damages in the equipment, in order to guarantee personal safety, also must carry out ground connection.During concrete enforcement just non-live metal body and function 16mm2 copper conductors such as accumulator stand 482, indoor cabling rack 484, indoor all devices casing 486 be connected to indoor row 21, adjacent indoor cabling rack 484 usefulness 16mm2 copper conductors carry out cross-over connection.
