Description
Technical field
The present invention relates to mobile communication base station ground network, especially relate to the mobile communication base station earthing method that reduces lightning current impact.
Background technology
For avoiding mobile communication base station to be subject to the impact of thunder and lightning, the earthing mode that generally take mobile communication base station is at present: by iron tower foundation, machine room basis, steel tower and machine room earth mat link together by Hot-dip zinc-coated flat steel sheet respectively, the interior annular ground connection of machine room is collected line and is connected with the reinforcing bar on machine room basis or is connected with machine room or steel tower earth mat by many earth connections, although this mode also can protecting group station equipment, but in the time that steel tower is struck by lightning, the lightning current that enters ground along steel tower will pass through iron tower foundation, machine room basis is strikeed back to annular ground connection in machine room and is collected on line, lightning current may collect line to annular ground connection in machine room and produce larger impact, cause equipment instant electric potential in machine room rise very high and damage.
Summary of the invention
The object of the invention is to provide a kind of mobile communication base station earthing method that reduces lightning current impact.
For achieving the above object, the present invention can take following technical proposals:
The mobile communication base station earthing method of minimizing lightning current impact of the present invention, comprises the steps:
One, the reinforced concrete beds electrical connection of four jiaos of support columns of antenna for base station steel tower is formed to the first endless metal earth electrode, on described the first endless metal earth electrode, evenly interval arranges multiple vertical metal earth electrodes downwards;
Two, below ground in base station machine room, arranges the second endless metal earth electrode around the geometric center point of base station machine room;
Three, around the interior metope of base station machine room, endless metal ground connection is set and collects line, collect vertical metal earth electrode is set downwards on line described endless metal ground connection, the lower end of described vertical metal earth electrode extends to below ground, and by earth connection and the second endless metal earth electrode and the electrical connection of base station machine room geometric center point;
Four, on the Grounding Grids at base station machine room geometric center point place, along continuous straight runs outwards arranges four radiation metal earth electrodes, and the angle between adjacent radiation metal earth electrode is 90 °; The length of every radiation metal earth electrode is 10-20 rice;
Five, around the reinforced concrete beds of four jiaos of support columns of antenna for base station steel tower, the 3rd endless metal earth electrode is set, on described the 3rd endless metal earth electrode, even interval is to being arranged with multiple metal Grounding Grids;
Six, described every radiation metal earth electrode and first, second, third ring-like metal earth electrode and base station machine room reinforced concrete beds infall are all electrically connected.
Described the first endless metal earth electrode is made up of reinforcing bar in column foot and Hot-dip zinc-coated flat steel sheet; Described second, third endless metal earth electrode is made up of Hot-dip zinc-coated flat steel sheet; Be arranged on first, spacing distance between multiple vertical metal earth electrodes on the 3rd endless metal earth electrode is 3-6 rice, or spacing distance is determined according to geographical environment.
The conclusion that the invention has the advantages that the feature of and thunder and lightning shunting theoretical according to electromagnetic shielding, that is: " when mobile communication base station steel tower is struck by lightning, the affect minimum of lightning current on machine room geometric center " carries out mobile communication base station ground grid design.Be electrically connected with iron tower foundation, machine room basis, machine station, first, second, third endless metal earth electrode respectively by described radiation metal earth electrode, therefore in the time that lightning current is released into ground along steel tower by earth mat, lightning current is minimum on the radiation metal earth electrode crosspoint place impact of base station machine room geometric center, collects line reach minimizing lightning current and affect the object of mobile communication base from this point by Hot-dip zinc-coated flat steel sheet and the second endless metal earth electrode being electrically connected to endless metal ground connection.
