Abstract
The invention discloses a half-floating-ground lightning protection grounding method for a small LTE (long term evolution) distributed base station. The method includes the steps of firstly, the metal shells of the indoor wireless communication transmission equipment, building baseband unit and power source distribution box of the small base station are electrically connected with a reference point busbar, mounted on an indoor or outdoor wall, through wires; the reference point busbar is not grounded; 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 protector; thirdly, an outdoor antenna is electrically connected with the metal shell of an outdoor radio remote unit and electrically connected with the lightning strips or reinforced steel bars of the corresponding building; 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 indoor building baseband unit respectively through an optical cable and a power feeder. By the method, the problem that the small distributed base station is hard in lightning protection grounding is solved, 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-sized LTE distributed base station half floating ground lightning protection method.
Background technology
The abbreviation of small-sized LTE(LongTermEvolution, popular is called 3.9G wireless network) distributed base station to build a station form flexibly as one, more and more be applied in each operator, be usually arranged in indoor, building or other not easily find the indoor public places of earth point.Small base station is built a station more flexible, lower to address challenges, directly can hang wall to install, solve operator to build a station difficult problem, but, because small base station often build non-telecom environment in, randomness is larger, without electrically connecing, therefore do not possess and adopt conventional lightning protection mode, therefore effectively can not 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:
