If battery 7 virtual voltages are lower than the float charge voltage of setting, it is 120 microseconds that single-chip microcomputer U1 exports a string cycle through the Pwm1 pin, and duty ratio is that 95% control impuls offers the triode V1 in the plastic drive circuit 3; Export high level simultaneously, make diode D4 light indicating operating status.If battery 7 virtual voltages are higher than the float charge voltage of setting, then export high level diode D5 is lighted, constant but pulse that width reduces of single-chip microcomputer U1 output cycle simultaneously, the every rising 0.02V of cell voltage does a stepping.Minimum duty cycle reduces to 5%, if this moment, battery terminal voltage also continued to rise when surpassing ceiling voltage 2.45V/ list lattice, the Pwm1 pin of single-chip microcomputer U1 stops output, and electronic switch 4 turn-offs, the battery two ends that do not have pulse current to be added to be repaired, battery terminal voltage falls after rise.The single-chip microcomputer U1 of every maintenance instrument is behind timing one-period (for example 500MS), pulse output is turn-offed in the capital, START OUT pin output high level is lighted the LED (not shown) in the photoelectrical coupler U6 simultaneously, make the START IN pin of next maintenance instrument single-chip microcomputer U1 become low level, trigger instrument automatically and go round and begin again and take turns to operate by high level.
The present invention is through using, and effect is as follows:
1, compares with existing small-pulse effect electric current prosthetic device, because this installs the single chip circuit U2 of with good grounds cell voltage and environment temperature auto-adjustment control reparation pulse current, so it is very big that its inceptive impulse electric current can be chosen, and reaches 0.1%～0.5%C10(C
10Nominal capacity for battery 10 hour rate currents discharges) even bigger, can add Speed maintenance process. 200Ah～1000Ah only needs just can remove in 48 hours to 168 hours the sulphur of clean inside battery The lead plumbate crystallization. And existing little current impulse prosthetic device overcharges to the impact of battery owing to will take the later stage into account, Its pulse current is generally chosen very little, with the small-pulse effect electric current battery is repaired from start to finish, and remediation efficiency is bright The aobvious reduction, the lead-acid accumulator of same capability often needs just can embody effect more than three months.
Although 2, the present invention has increased pulse maintenance electric current, under the control of enabling signal circuit 1, whole UPS How many platform maintenance instruments no matter system installed, and only has a maintenance instrument in work in the unit interval, and this subtracts greatly The pulse ripple interference problem of having brought when having lacked the instrument synchronous working. Make ups system high-capacity sealed in installation Behind the lead-acid accumulator on-line maintenance instrument, work that can be safe and reliable.
