Description

Small-sized LTE distributed base station half floating ground lightning protection method
Technical field
The present invention relates to communication base station lightning protection method, especially relate to small-sized LTE distributed base station half floating ground lightning protection method.
Background technology
The abbreviation of small-sized LTE(LongTermEvolution, the popular 3.9G wireless network that is called) distributed base station is as the one form of building a station flexibly, more and more be applied in each operator, be conventionally arranged in indoor, building or other are difficult for finding indoor public places of earth points. Small base station is built a station more flexible, require lower to address, can directly hang wall installs, solve operator's difficult problem of building a station, still, because small base station is often built non-telecommunication environment in, randomness is larger, without electrically connecing, therefore do not possess and adopt conventional lightning protection mode, therefore can not effectively ensure the lightning protection safety of small base station.
Summary of the invention
The object of the invention is to provide a kind of small-sized LTE distributed base station half floating ground lightning protection method.
For achieving the above object, the present invention takes following technical proposals:
Small-sized LTE distributed base station of the present invention half floating ground lightning protection method, carry out according to following step:
The first step, small base station is positioned to indoor wireless communication transmissions equipment, baseband processing unit (BBU--BuildingBasebandUnit) and power supply distribution box metal shell by wire and the reference point bus-bar electrical connection being arranged on indoor or outdoors wall; Described reference point bus-bar is earth-free, that is: earth-free with the metal shell equipotential of described wireless communication transmissions equipment, baseband processing unit and the power supply distribution box of reference point bus-bar electrical connection;
Second step, external power source inlet wire is electrically connected by the power input interface of differential mode protector and described power supply distribution box;
The 3rd step, by exterior aerial and the metal shell electrical connection that is arranged on outdoor Remote Radio Unit (RRU--RadioRemoteUnit), and with lighting proof strip or the reinforcing bar electrical connection of place building;
The 4th step, by the communication interface of described Remote Radio Unit and power input interface respectively by optical cable and power feeder be arranged on the communication interface of indoor baseband processing unit and power interface is corresponding is connected.
The invention has the advantages that the difficult problem of small distributed base station lightning protection ground connection that solved, provide under the non-exposed environments of thunder and lightning small base station equipment end to adopt earth-free mode floatingly, that is: the metal shell equipotential of described wireless communication transmissions equipment, baseband processing unit and the power supply distribution box being electrically connected with described reference point bus-bar is earth-free; Described exterior aerial and the metal shell electrical connection that is arranged on outdoor Remote Radio Unit, and be electrically connected with lighting proof strip or the reinforcing bar of building; The security reliability that has improved small base station, has reduced potential safety hazard.
Brief description of the drawings
Fig. 1 is the small-sized LTE distributed base station half floating ground lightning protection earthing system schematic diagram of implementing according to the inventive method.
Detailed description of the invention
As shown in Figure 1, small-sized LTE distributed base station of the present invention half floating ground lightning protection method, carry out according to following step:
The first step, the metal shell that small base station is positioned to indoor wireless communication transmissions equipment 1, baseband processing unit 2 and power supply distribution box 4 are electrically connected by wire and the reference point bus-bar 3 being arranged on indoor or outdoors wall; Described reference point bus-bar 3 is earth-free, that is: the metal shell equipotential of described wireless communication transmissions equipment 1, baseband processing unit 2 and the power supply distribution box 4 being electrically connected with reference point bus-bar 3 is earth-free;
Second step, the power input interface electrical connection with described power supply distribution box 4 by differential mode protector 5 by external power source inlet wire 6;
The 3rd step, by exterior aerial 7 and the metal shell electrical connection that is arranged on outdoor Remote Radio Unit 8, and with lighting proof strip or the reinforcing bar electrical connection of place building;
The 4th step, by the communication interface of described Remote Radio Unit 8 and power input interface respectively by optical cable and power feeder be arranged on the communication interface of indoor baseband processing unit 2 and power interface is corresponding is connected.
