2The aluminium cable.For three modules of local side, can adopt the system of its 2+1 backup functionality, make whole system more stable.
Can be found out by above-mentioned situation, the utlity model has following characteristics:
1, power transmission mode:
Direct current has remarkable advantages more than alternating current, is mainly reflected in characteristics such as direct current cables circuit transmission capacity is big, line loss is little, it is aging to be difficult for, the life-span is long.Because dc voltage is constant, does not produce alternating magnetic field, so same insulation thickness and core section cable, it is more much bigger than being used for ac transmission to be used for direct current transportation, and promptly the direct current supply line cost is lower.Existing resistance in the ac transmission circuit has inductance and electric capacity again, and has only resistance to work in the direct current transmission line, and inductance and electric capacity are inoperative, do not have the current loss of inductance and electric capacity, so its loss is littler, and transmitting range is farther, adopts 2*6mm
2Aluminium cable can realize the remote power feeding of 7-10 kilometer.
2, use transmission security
Utilize composite cable or cable to provide remote power feeding,,, only between two groups of lines, produce potential difference owing to adopt the design that suspends over the ground though supply power voltage surpasses 200V for communication base station; Wherein can not produce safety problems such as electric leakage when contact during one group of line, have only just to produce pick-up current when contacting two groups of lines simultaneously, at this time equipment can short-circuit protection, temporarily stops power supply.When base station equipment is not opened electricity, when non-loaded, electric power system only sends detection signal, and whether monitoring base station is online, just starts power supply in case find that the base station load is on the throne.If open circuit or short circuit phenomenon appear in line fault, remote power feeding power supply local side apparatus can monitor and stop power supply automatically, enters detected state, periodically sends the pulse monitor signal, until power supply is continued after recovering normally again in circuit and base station.But also have earth leakage protective: descend for any one insulation against ground impedance of loop when far away, when producing to earth-current, system's cutoff high output; The heavy current invading protection: when system detects, have civil power and power supply transmission line to produce when overlapping, system cuts off the high pressure output of local side;
3, expense is low, and is economical and practical:
Because light thousand communication base station is used for remote districts, the expense of setting up power supply separately is higher, and each communication base station is equipped with UPS, generally speaking, in the Plain average cost is on average even 7～100,000 yuan of 5～70,000 yuan, mountain area, also need dispose complementary power supplies such as UPS, also need increase by 1～30,000 yuan of left and right sides expense, and annual maintenance cost all (wherein comprises expenses such as personnel, oily expense, fare, maintenance device, generating) about 4000-6000 unit.And adopt the remote power feeding expense to include only two parts, and the one, photoelectricity optical cable expense or cable expense, another is the remote power feeding cost of equipment, with 1.5mm on the market now
2Composite cable is an example, only increases by 3000 yuan/km than ordinary optical cable, and to make somebody a mere figurehead aluminium cable 4mm on the market
2The aluminium cable is an example, and every km price is less than 2000 yuan, and the remote power feeding cost of equipment is about 1-2 is ten thousand yuan, and with two kilometers distance calculation, whole cost is less than 30,000 yuan, and the power-source maintenance expense almost can be ignored in the future.Communication base station remote power feeding generally speaking not only has and need not safeguard power circuit in the future, need not regularly pay the electricity charge but also have advantage such as do not have a power failure, also advantage such as time saving and energy saving on engineering.
