Abstract
The invention discloses a full-floating-ground lightning protection grounding method for a small base station under an unexposed environment. The method includes the steps of firstly, the metal shells of the wireless communication transmission equipment, the building baseband unit and the power source distribution box which are mounted on an indoor wall are electrically connected with a reference point busbar mounted on an indoor or outdoor wall; secondly, an external power source incoming line is electrically connected with the power input interface of the power source distribution box through a differential mode lightning protector; thirdly, an outdoor antenna is electrically connected with the metal shell of an outdoor radio remote unit and electrically connected with the outdoor busbar; fourthly, the communication interface and the power input interface of the radio remote unit are correspondingly connected with the communication interface and the power interface of the building baseband unit, mounted on an indoor wall, respectively through an optical cable and a power feeder. By the method, the problem that the small base station is hard in lightning protection grounding is solved, the small base station adopts the full-floating-ground manner under the lightning unexposed environment, safety and reliability of the small base station are increased, and potential safety hazard is lowered.
Description
Technical field
The present invention relates to communication base station lightning protection method, especially relate to small base station entirely floating under non-exposed environment
Ground lightning protection method.
Background technology
The abbreviation of small-sized lte(longtermevolution, popular is referred to as 3.9g wireless network) distributed base station conduct
One kind is flexibly built a station form, more and more applies in each operator, be commonly installed indoors, in building or other not
Easily find the indoor public places of earth point.Small base station builds a station comparison flexibly, relatively low to address challenges ratio, can directly hang wall
Install, solve the problems, such as that operator builds a station hardly possible, but, because small base station often build non-telecom environment in, randomness compares
Greatly, no electrically can connect, therefore not possess using conventional lightning protection mode, therefore can not effectively ensure small base station
Lightning protection safety.
Content of the invention
Present invention aim at providing a kind of floating ground lightning protection method entirely under non-exposed environment for small base station.
For achieving the above object, the present invention takes following technical proposals:
Floating ground lightning protection method entirely under non-exposed environment for the small base station of the present invention, enters as steps described below
OK:
The first step, by the wireless communication transmissions equipment being arranged on indoor wall, baseband processing unit (bbu--
) and the metal shell of electrical power distribution case and the reference point sink being arranged on indoor or outdoors wall buildingbasebandunit
Stream row's electrical connection；
Second step, external power source inlet wire is passed through the power input interface of differential mode lightning guard and described electrical power distribution case
Electrical connection；
3rd step, by the gold of exterior aerial and Remote Radio Unit (rru--radioremoteunit) installed outdoors
Belong to shell electrical connection and arrange electrical connection with outdoor junction；
4th step, the communication interface of described Remote Radio Unit and power input interface are passed through respectively optical cable and power supply feedback
The communication interface of line and the baseband processing unit being arranged on indoor wall and power interface is corresponding connects.
The invention has the advantages that solving the problems, such as that small base station lightning protection is difficult, there is provided in the non-exposed ring of thunder and lightning
Under border, small base station is using entirely floating ground mode it may be assumed that described wireless communication transmissions equipment, baseband processing unit and electrical power distribution case
The earth-free and described reference point bus-bar electrical connection of metal shell isoelectric level, described exterior aerial and radio frequency installed outdoors
Electrical connection is arranged with outdoor junction after the metal shell electrical connection of extension unit；Reference point bus-bar, outdoor junction are arranged all not
Ground connection floats ground earthing mode entirely to constitute, and improves the security reliability of small base station, reduces potential safety hazard.
Brief description
Fig. 1 is that ground lightning protection earthing system structure of entirely floating under non-exposed environment for the small base station is shown implemented according to the invention
It is intended to.
Specific embodiment
As shown in figure 1, small base station of the present invention under non-exposed environment entirely float ground lightning protection method, according under
State step to carry out:
The first step, by the wireless communication transmissions equipment 1 being arranged on indoor wall, baseband processing unit 2 and electrical power distribution
The metal shell of case 4 is electrically connected with the reference point bus-bar 3 being arranged on indoor or outdoors wall；
Second step, external power source inlet wire 6 is passed through the power input of differential mode lightning guard 5 and described electrical power distribution case 4
Interface Electrical connects；
3rd step, by the metal shell electrical connection of exterior aerial 7 and Remote Radio Unit 8 installed outdoors and and room
Exchange flow row 9 electrical connection；
4th step, the communication interface of described Remote Radio Unit 8 and power input interface are passed through respectively optical cable and power supply
The communication interface of feeder line and the baseband processing unit 2 being arranged on indoor wall and power interface is corresponding connects.Described reference point
Bus-bar 3, all earth-free floating ground lightning protection earthing system entirely with the described small base station of composition of outdoor junction row 9.
