Abstract
The utility model discloses a transient protection system of a mobile communication base station based on thunder and lightning lead-in ports. The mobile communication base station is composed of signal transmission equipment, a transceiver, a switching power supply, an incoming power line distribution box, a transceiver antenna, a lightning rod, a grounding bus, an antenna feeder and a grounding grid; corresponding lightning protection devices are respectively arranged at a power port, a feed port, a signal port and a grounding port of the mobile communication base station; and the antenna feeder is directly connected with the grounding grid through a grounding bar. According to the transient protection system provided by the utility model, the mobile communication base station is taken as a whole, and the main ports affected by thunder and lightning is determined by analyzing and determining thunder and lighting lead-in channels. As secondary effect produced by lightning current at the grounding port due to the transient ground potential rise caused by lightning current can affect the power port, the signal port and a direct-current output end, the transient equipotential thunder and lightning protection method is adopted to take lightning protection measures at each port, and no lightning protection device needs to be arranged on the antenna feeder, thereby well addressing the problem of lightning protection of the mobile communication base station.
Description
Technical field
The utility model relates to the mobile communication base station protection system, especially relates to the mobile communication base station transient protective system based on the thunder and lightning inlet port.
Background technology
Lightning Disaster is one of the most serious natural calamity, and the communication disruption that communication base station suffers lightning damage and causes has thus not only caused huge economic loss, and has had a strong impact on the safe operation of communication network.At present, the method that the mobile communication base station lightning protection protective system takes the stable state equipotential to connect more, be about in the base station can ground connection equipment directly be connected with the base station earth mat.But, also have in the base station many can not directly grounded system, such as power port, feed port, signal port, antenna feeder port etc.Power port: with regard to the broken by lightning ratio, the power supply class accounted for for about 90% (comprising transformer, distribution box, pressurizer, rectification module, air-conditioning mainboard, illuminator etc.).These all are connected with power line by the equipment of broken by lightning, in thunderbolt power lead-ining line and thunderbolt during steel tower, because the surge that earth potential raises or thunder and lightning magnetic field produces at equipment room will cause the insulation of equipment and internal component breakdown.Signal port: when the CPU of class signal equipment such as wireless base station, user's plate, 2Mb/s interface, microwave transmission interface, environmental monitoring, transducer, fire-fighting control board, little microwave etc. are struck by lightning, often all be connected with holding wire in the machine room by the equipment of broken by lightning.Feed port: what all kinds of distributed base stations were different from traditional base station is the RRU(Remote Radio Unit) far-drawing system, the RRU far-drawing system comprises the modes such as direct current, control, signal, GPS, microwave, optical transmission device, and its transmission medium that adopts has radio frequency cable, control line, direct-current tie, immediate frequency cable, optical cable etc.These far-drawing systems are owing to be exposed to external environment condition, its transmission medium in the LPZOB district (except optical cable, these transmission mediums are all taked the form of coaxial cable or composite cable, the actual critical zone that belongs to LPZOB and LPZ1), therefore increased the possibility that thunder and lightning is introduced.The antenna feeder port: people will be from the lightning current of antenna feeder as the main introducing channel to the base station thunder and lightning in the past, and showed that by theory analysis and calculating the antenna feeder port is not the main channel of thunder and lightning.Grounding ports: mainly be that the potential rise of moment is on the impact of equipment for grounding ports.When having thunderbolt to release by earth mat, then can cause the earth potential liter of moment, so that the poor change of the dynamic potentials between the DC power supply positive and negative electrode is large, cause equipment sensitive part (rectification module and transceiver etc.) to damage.And the quadratic effect that transient state earth potential liter produces is huge to power port and signal port damage, the damage of ordinary circumstance power port is all relevant with grounding ports, how the mobile communication base station is done as a whole, prevent that lightning current from introducing from above-mentioned port, the flow through damage of the quadratic effect that the transient state earth potential that produces on the earth electrode causes of the particularly impact of grounding ports, lightning current yet there are no all relevant reports.
Summary of the invention
The utility model purpose is to provide a kind of mobile communication base station transient protective system based on the thunder and lightning inlet port.
For achieving the above object, the utility model is taked following technical proposals:
Mobile communication base station transient protective system based on the thunder and lightning inlet port described in the utility model comprises the mobile communication base station that is made of signal transmission apparatus, transceiver, Switching Power Supply, in-wiring distribution box, dual-mode antenna, lightning rod, earth bus, antenna feeder, earth mat; Main port in described mobile communication base station: power port, feed port, signal port, grounding ports are respectively arranged with corresponding lightning protection device, and antenna feeder directly links to each other with earth mat by earthing bar.
The lightning protection device that is arranged on described power port is the lightning protection for power supply that is connected between described in-wiring distribution box and the earth bus; The lightning protection device that is arranged on described feed port is the feed lightning protection device that is connected between feed line and the earth bus; The lightning protection device that is arranged on described signal port is the siganl thunder-proof device that is connected between holding wire and the earth bus, and described holding wire is the communications cable between described transceiver and the signal transmission apparatus; One of lightning protection device that is arranged on described grounding ports is the DC lightning prevention device that is connected between Switching Power Supply leading-out terminal and the earth bus, and the magnitude of the protective device of power port, signal port should be considered the impact of grounding ports simultaneously.
The utility model advantage is the mobile communication base station is done as a whole, channel by each thunder and lightning introducing of Analysis deterrmination, determined the main port of effects of lightning, because causing lightning current, the transient state earth potential liter that lightning current causes to have influence on power port, signal port, dc output end in the quadratic effect that grounding ports produces, therefore utilize transient state equipotential lightning protection method and then take lightning protection measures at each port, and antenna feeder need not to add lightning protection device, thereby has solved the mobile communication base station Lightning Protection extraordinaryly.
