Grounding reference point optimizing and connecting method for star connection system of mobile communication base station

Abstract

The invention discloses a grounding reference point optimizing and connecting method for a star connection system of a mobile communication base station. The method comprises the steps of newly arranging an indoor grounding bar beside a distribution box and a first-level anti-thunder box in the mobile communication base station, electrically connecting the newly arranged indoor grounding bar with the original indoor grounding bar in the mobile communication base station by a lead, disconnecting the connecting leads between the original indoor grounding bar and the distribution box, the first-level anti-thunder box and an anti-thunder earth screen of the mobile communication base station, electrically connecting the newly arranged indoor grounding bar with a lead-out conductor of the anti-thunder earth screen of the mobile communication base station and then electrically connecting the newly arranged indoor grounding bar with the grounding end of the first-level anti-thunder box and the distribution box. The grounding reference point optimizing and connecting method for the star connection system of the mobile communication base station has the advantages of solving the problem of overlong leaking path of the thunder current caused by the overlong distance between the distribution box and the first-level anti-thunder box and the indoor grounding bar of the currently operated mobile communication base station, improving the anti-thunder capacity of the mobile communication base station and avoiding large-scale alteration on the original line.

Description

technical field [0001] The invention relates to a grounding system of a mobile communication base station, in particular to an optimized connection method for a grounding reference point of a star connection system of a mobile communication base station. Background technique [0002] The power line entering the mobile communication base station is the main channel to introduce lightning damage, so the lightning protection of the mobile communication base station power supply system is particularly important. Such as figure 2 As shown, in many existing mobile communication base stations that have been in operation, the distance between the distribution box 2 and the grounding bar 5 installed in the computer room 1 and the grounding wire of the first-level lightning protection box 3 and the grounding bar 5 are relatively long. When the current enters the computer room 1 along the power line, the lightning current will generate a huge residual voltage on the ground wire of the...

Problems solved by technology

The transformation method currently adopted is to move the distribution box 2 and the first-level lightning protection box 3 to the side of the grounding bar 5, or to move the grounding bar 5 to the side of the distribution box 2 and the first-level lightning protection box 3. This method often needs to re-arrange the power lines and signal lines in the mobile communication base station, which is very time-consuming and labor-intensive.
