Description of the drawings
Fig. 1 is this utility model power supply system for communications structural representation；
Fig. 2 is this utility model power supply system for communications schematic diagram.
Specific embodiment
This utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, this utility model power supply system for communications include the accumulator battery of 4 different models, battery combiner,
High frequency switch power and power-supply controller of electric.4 accumulator batteries can be connected respectively by power line with battery combiner.Battery is closed
Road device connects high frequency switch power by power line.
Battery combiner and high frequency switch power in this utility model is by Beijing Dongliyuan Technology Co., Ltd
Production.
As shown in Fig. 2 main path switch K1, K2, K3, K4 are respectively mounted between battery combiner and 4 accumulator batteries with pair
Way switch K5, K6, K7, K8, form major-minor road and coordinate.Auxiliary switch in same group storage battery group is mutually put up a bridge with master switch and is connected,
That is connection, K7 and K3 bridging connection that K5 is connected with K1 bridgings, K6 and K2 puts up a bridge, K8 and K bridging connections；Secondary way switch K5 and main road
Series diode D1, pair series diode between way switch K6 and the input of main path switch K2 between the input of switch K1
D2, pair series diode D3 between way switch K7 and the input of main path switch K3, secondary way switch K8 are defeated with main path switch K4
Enter series diode D4 between end.
Each accumulator battery connects respectively the monitoring unit and power-supply controller of electric of battery combiner by data wire.Battery combining
The monitoring unit and high frequency switch power of device connects power-supply controller of electric by data wire respectively.
Under daily normal operation circumstances, power-supply controller of electric is monitored to accumulator battery 1- accumulator battery 4, is closed by battery
Road device control circulation carries out single group discharge and recharge.During charging, full of accumulator battery 2 is switched again, accumulator battery 2 is full of accumulator battery 1
Rush accumulator battery 3 again afterwards, the like circulation, the charging/discharging voltage and electricity of different batteries can be set in battery combiner
Stream, realizes the homologous ray operation of different capabilities battery, lithium iron battery, so need not require Switching Power Supply synchronization in battery dilatation
Dilatation.
When mains failure, power-supply controller of electric switches to rapidly preferential accumulator battery and (is defaulted as storing by battery combiner
Set of cells 1) electric discharge, discharged successively by accumulator battery 1-4.Guarantee that battery begins using secondary road bridging switching between different batteries group
It is online eventually, as shown in Fig. 2 when accumulator battery 1 switches accumulator battery 2, first closing the secondary road A ＇ of set of cells 1, master is cut off afterwards
Road A, the main road B of closure accumulator battery 2, then the secondary road A ＇ of accumulator battery 1 are cut off, now the voltage of accumulator battery 2 is higher than electric power storage
Pond group 1, the main road of accumulator battery 2 is not turned on to the road diode D1 of accumulator battery 1, plays good anti-retroaction, and Jing this analogizes
Discharged successively.So as to ensure that in handoff procedure, battery is online all the time, it is ensured that system not power-off, after civil power incoming call, it is
System switches to accumulator battery 1 and is charged, and fills after a wheel successively, switchs to battery float.
Test one：Battery combiner electric discharge switch test
When battery discharge management test set of cells is arbitrarily online, by cutting that field power supply voltage modulated battery combiner is arranged
Change voltage (voltage modulated 49.5V during on-the-spot test simultaneously closes off power source master switch power input and rehearses power failure), discharge time
After for 5 minutes, the secondary way switch D.C. contactor coil of the current online accumulator battery 1 of battery combiner is measured simultaneously with circuit tester
The main path switch direct current of voltage (first measuring current online contactor coil voltage before this) and next Battery pack (i.e. accumulator battery 2)
Contactor coil voltage, test voltage is 49.02V, it can be seen that seamless switching is capable of achieving when set of cells switches and will not be made
There is flash phenomenon in load.
When exchange has a power failure in actual motion, online accumulator battery is switched to preferential accumulator battery and carries out battery discharge, excellent
When first accumulator battery is discharged to switching voltage (system factory default setting 46.4V, can User Defined arrange), switch to next
Group storage battery discharges；By parity of reasoning, and accumulator battery discharges into successively last group storage battery group.Last group storage battery group electric discharge
To the principal of the power supply system for communications, during second magnitude of voltage, the once load of corresponding cut-out communication power supply and secondary negative
Carry, complete combiner battery power discharge.
Test two：Battery fills management test
After accumulator battery electric discharge has been tested, master switch power supply electrifying is given, checks Switching Power Supply control unit current state,
Be shown as filling state, when battery full of after the achievable next group storage battery of automatically switching enter and fill, check charging current in
Pincerlike meter current error is less than 1A within normal range.
Test three：Battery float management is tested
After the completion of 4 accumulator batteries are filled, then the current state of high frequency switch power control unit is observed, be shown as floating
State is filled, Jing is set to battery combiner floating charge conversion time 1 hour, battery combiner turns automatically after the setting time is reached
It is changed to next Battery pack and enters floating charge state.4 accumulator batteries are converted after 4 hours, and exception does not occur in period.
Can be according to actual battery storage situation by variety classes, model, capacity and batch battery in actually used process
In being arranged at same accumulator battery, realize that integration is used by battery combiner, solve the problems, such as battery combining.This utility model reality
Show different capabilities, different manufacturers, different batches, the integration of ferrum lithium plumbic acid variety classes battery to use, be capable of achieving base station battery
Rationally dilatation, reduces cost of investment that battery updates, reuse fairly large number of storage battery, extends battery, drop
Low lead-acid battery scraps speed, so as to greatly lift the maintenance work level of communication base station battery, effectively responds country's section
Can reduce discharging and call, protect ecological environment.
Specific embodiment of the present utility model is described above, but this utility model is not limited to the above and retouches
State.For a person skilled in the art, any equal modifications and substitutions to the technical program are all in this utility model
Scope among.Therefore, the impartial conversion made under without departing from spirit and scope of the present utility model and modification, all should cover
In the range of this utility model.
