Description
Technical field
The utility model relates near base station transformer mobile communication base station, relates in particular to the base station transformer lightning protection earthing system in the time that mobile communication base station and base station transformer are less than 30 meters apart.
Background technology
The mobile communication base station of operator, much build suburb or field at present.In recent years, along with the development of mobile communications industry, mobile communications network scale constantly expands, the scope that mobile communication base station covers also by city, suburb to mountain area, field expands.For guaranteeing the power supply to mobile communication base station, need special base station transformer to become 380V voltage to power to mobile communication base station 10kV voltage transitions.Conventionally, base station piezoelectric transformer is located at side, mobile communication base station, because mobile communication base station thunder and lightning environment is more severe, therefore base station transformer or high and low pressure lightning arrester are easily by broken by lightning, cause mobile communication base station power failure or cause mobile communication base station outage, this situation is occupied suitable ratio in the accident of mobile communication base station, especially more like this in the time that mobile communication base station and base station transformer are less than 30 meters apart.
Summary of the invention
The utility model object is to provide a kind of mobile communication base station transformer lightning protection earthing system.
For achieving the above object, the utility model is taked following technical proposals:
Mobile communication base station described in the utility model transformer lightning protection earthing system, comprises mobile communication base station ground network and base station transformer and base station transformer grounding net; Described base station transformer grounding net is equilateral triangle structure, and the geometric center point of described equilateral triangle ground network and three summits are electrically connected by horizontal grounding objects; The three-in-one earth point of base station transformer and the electrical connection of lightning rod down conductor are also electrically connected with the geometric center point of equilateral triangle ground network; Equilateral triangle ground network is electrically connected by two points of horizontal grounding objects and mobile communication base station ground network respectively near two summits of mobile communication base station ground network one side; At base station high voltage side of transformer, base station special high pass flow thunder and lightning lightning arrester is set, after earth point, the base station transformer case of the neutral point of base station transformer, described base station special high pass flow thunder and lightning lightning arrester is connected electrically to a bit, is electrically connected with described lightning rod down conductor.
The length of side >=3 meter of described equilateral triangle ground network.
The utility model advantage is to realize and effectively prevents the mobile communication base station transformer object of being struck by lightning.
Accompanying drawing explanation
Fig. 1 is the special high pass flow of base station described in the utility model transformer and base station, high-pressure side thereof thunder and lightning arrester ground schematic diagram.
Fig. 2 is the connecting structure for electrical equipment schematic diagram of base station described in the utility model transformer grounding net and mobile communication base station ground network.
Embodiment
As shown in Figure 1, 2, mobile communication base station described in the utility model transformer lightning protection earthing system, comprises mobile communication base station ground network 1 and base station transformer 2 and base station transformer grounding net; Described base station transformer grounding net is equilateral triangle structure, the length of side >=3 meter of described equilateral triangle ground network 3, and its geometric center point 4 and three summits 5,6,7 are electrically connected by horizontal grounding objects; The three-in-one earth point of base station transformer 2 and lightning rod 8 down conductor electrical connections are also electrically connected with the geometric center point 4 of equilateral triangle ground network 3; Equilateral triangle ground network 3 is electrically connected by two points of horizontal grounding objects 9,10 and mobile communication base station ground network 1 respectively near two summits 5,6 of mobile communication base station ground network 1 one sides; Base station special high pass flow thunder and lightning lightning arrester 11 is set in base station transformer 2 high-pressure sides, after the earth point of the neutral point of base station transformer 2, described base station special high pass flow thunder and lightning lightning arrester 11, the shell of base station transformer 2 are connected electrically to a bit, is electrically connected with described lightning rod 8 down conductors.
The utility model lightning protection earthing system electrical principle is summarized as follows:
By the equilateral triangle ground network of described base station transformer 23 and 1 use horizontal grounding objects 9,10 electrical connections of mobile communication base station ground network, the ground network area of its formation reaches maximum, earth resistance reaches minimum value, can effectively carry out diffusing to lightning current, reduce the use of the Grounding Grids 12 of mobile communication base station ground network 1.Adopt base station special high pass flow thunder and lightning lightning arrester 11 to there is high pass flow, the characteristic of low residual voltage (8/20 μ S 20kA residual voltage is less than 50kV), (what mobile communication base station 13 adopted at present is all Civil High Pressure lightning arrester in the time of thunderbolt, to be not easy damage, this lightning arrester through-current capacity is low, ginseng is pressed high, easily by broken by lightning), because residual voltage is less than 50kV, can guarantee that transformer insulated being unlikely to punctures, and save the lightning arrester of low-pressure side, this be because the machine room distribution box first order lightning protection device through-current capacity of mobile communication base station 13 far above the magnitude of former low-pressure side lightning arrester, so it is not fragile, reduce difficulty of construction, save spending.The three-in-one earth point of base station transformer 2 and the electrical connection of the downlead of lightning rod 8, object is that large Y-connection mode is converted into starlet shape connected mode, to improve the position of reference point, reduces senior staff officer's pressure that earth connection causes because of line length.
