Embodiment Construction
[0012] Such as figure 1 As shown, the lightning protection grounding method for the small base station described in the present invention in a non-exposed environment is carried out according to the following steps:
[0013] The first step is to electrically connect the metal casing of the wireless communication transmission equipment 1, the baseband processing unit 2 and the power distribution box 4 installed on the indoor wall to the reference point bus bar 3 installed on the indoor or outdoor wall;
[0014] The second step is to electrically connect the external power supply line 6 to the power input interface of the power distribution box 4 through the differential mode lightning protector 5;
[0015] The third step is to electrically connect the outdoor antenna 7 to the metal shell of the remote radio frequency unit 8 installed outdoors and to electrically connect the outdoor power outlet 9;
[0016] Step 4: Correspondingly connect the communication interface and power i...

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 [0001] The invention relates to a lightning protection and grounding method for a communication base station, in particular to a fully floating lightning protection and grounding method for a small base station in a non-exposed environment. Background technique [0002] Small LTE (abbreviation for LongTerm Evolution, commonly known as 3.9G wireless network) distributed base stations, as a form of flexible station construction, are more and more used in various operators. They are usually installed indoors, in buildings or in other places where it is difficult to find Indoor public places of locations. The construction of small base stations is relatively flexible, with relatively low requirements for addresses. It can be installed directly on the wall, which solves the problem of difficulty for operators to build stations. However, since small base stations are often built in non-telecom environments, they are relatively random and have no electrical connecti...
