Description
Affiliated technical field
The utility model relates to a kind of accumulator testing device, refers in particular to a kind of battery pack that applies to the communication machine room fundamental power supply and descends (online) to test the proving installation of this accumulator capacity in working order.
Background technology
Power supply is an essential important component in the communication network, and the quality of quality of power supply is directly connected to the unimpeded of whole communication network.In mechanics of communication, equipment such as transmission, transmission, reception, calling all are to use the power supply of direct current-48V as communication apparatus, and uninterrupted and stable interference-free in order to realize communication apparatus work, all communication apparatus power-supply systems all are equipped with battery pack.The principle of work of accumulator is to pass through chemical reaction: Pb (negative pole)+PbO2 (positive pole)+2H2SO4=2PbSO4+2H2O (exoelectrical reaction) stores and discharges electric energy.
Because communication power supply is very important, particularly require central machine room not have a power failure for a long time, so the battery pack that the communication apparatus power-supply system is equipped with is in full state of charge for a long time, cause active substance to solidify easily, the discharge capability of battery is sharply descended, the safe operation of communication apparatus is brought great hidden danger.
Stipulate according to the communication power supply service regulations: the discharge test that it is 30%-40% that system disposition has battery pack should be carried out degree of depth every year, to carry out degree of depth in per 3 years and be 100% discharge test, reaching the battery pack in 6 years tenure of use, is 100% discharge test with regard to carrying out degree of depth every year.Therefore, the accumulator capacity test instrumentation obtains a large amount of application in the communication power supply battery service in recent years.
Method of testing commonly used at present mainly contains:
Method 1: breaking away from the accumulator slave unit, utilize intelligent load that battery is discharged, use intelligent charge equipment to battery charge again, the back is also gone up system again to battery.This method needs the omnidistance guard of personnel at discharge process, and discharge, charging need chronicly, in addition, in time generates electricity in the time of also need preparing generator in order to system blackout, and whole process wastes time and energy, and electric energy is wasted in heating again during discharge.
Method 2: artificially interchange is cut off, allowed accumulator, with the online capacity of accumulator tester accumulator is tested then directly to the load equipment discharge.Though this method also is online discharge, discharge current can't be regulated, and discharge process needs personnel to note the guard, otherwise battery has been when having put, and power failure can cause the accident of equipment downtime.
Method 3: adopt the internal resistance of internal resistance test device test accumulator, judge the quality of battery by the variation of internal resistance.But because the volume change of internal resistance variation and accumulator does not have linear relationship, i.e. internal resistance changes intuitively reaction cell volume change, also needs to confirm by discharge the volume change of battery, still can't easily-testing.
The utility model content
The purpose of this utility model be to provide a kind of easy to operate, need not applied load, can be to communication apparatus direct-on-line heavy-current discharge, and solved the accumulator on-line test device of the safety problem of discharge process.
For achieving the above object, the utility model adopts following structure:
A kind of accumulator on-line test device comprises the monomer measurement module, CPU control module, power module; CPU control module control monomer measurement module and power module, and with measurement result and power module information transmission to the storage of CPU control module, handle, wherein, be parallel with a constant flow module on the power module, make the current constant of power module and constant flow module output.
Power module comprises power supply, charges and discharge control module, to the charge and discharge of battery and control.
The CPU control module comprises display, gauge tap, CPU, keyboard and USB module, and the CPU control module is controlled power module, monomer measurement module, and the data that the monomer measurement module collects are stored and handled.
The monomer measurement module can be wired monomer measurement module or wireless monomer measurement module.Comprise radio frequency chip, process chip (CPU), transmit receive antenna, be used for the data acquisition and processing (DAP) of battery cell, and the transmission of data receives.
Positive source in the described power module is connected in series a contactor, the two ends of this contactor powerful bypass diode in parallel.
Described accumulator on-line test device is provided with relief cable connector and connecting line.
The advantage of said structure is: need not newly-increased heating load, economize on electricity (putting the electric energy of the battery save 250KW of one group of 3000AH) at discharge process; Realize the online constant-current discharge of grouping, safe and effective measurement accumulator capacity.
Wireless monomer collection, the monomer voltage of on-line monitoring battery pack discharge process and charging process changes, and effectively prevent the electric battery overdischarge or overcharge, and fast wiring is convenient.
In addition, for the battery pack that guarantees to discharge is real-time the connection with communication system, contactor can stop at civil power, when the voltage of accumulator is identical with system voltage, adhesive rapidly, the battery pack connecting system, the while is in the high-power bypass diode of the two ends of contactor parallel connection, the more real-time connection of assurance device.
Also have, when civil power stopped, accumulator needed big electric current to power devices, if cable has only one the phenomenon of generating heat may occur, have very big pressure drop simultaneously, auxiliary cable connector and connecting line can guarantee the power supply capacity of battery pack to communication system.
