Grounding method for semi-floating lightning protection of small LTE distributed base stations

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 [0001] The invention relates to a lightning protection and grounding method for a communication base station, in particular to a semi-floating lightning protection and grounding method for a small LTE distributed base station. 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 connection. Therefore...

Problems solved by technology

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 connection. Therefore, there is no conventional lightning protection grounding method, so the lightning protection safety of small base stations cannot be effectively guaranteed
