Description
Technical field:
The present invention relates to a kind of maintaining method of storage battery, particularly a kind of on-line maintenance method of accumulator capacity of direct current operative power source of substation.
Background technology:
The sealed cell that transformer station uses is widely used in the interior dc operation power supply system in station as stand-by power supply, but because maintenance is improper, the battery spoilage is very high, and present statistical life is for when use 3 years left and right sides during the time, and structural capacity will drop to below 80%.Structural capacity is meant the actual capacity after the abundant charging of battery, in the battery use, the hump process of the structural capacity experience of battery one " rising earlier; descend again ", the shape of hump depends on manufacturing process and service condition, structural capacity is lower than the use standard can make the retained storage capacity of storage battery on the low side, this is a reason that causes the batteries whole volume on the low side, after storage battery used a period of time, for various reasons, the structural capacity of battery will drop to unsafe limit.
Sealed cell is not " non-maintaining " battery, needs to safeguard.Current at present maintaining method is that it is detected float charge voltage, clean appearance mostly.To the electric ability of its key performance, promptly the structural capacity of battery and retained storage capacity but do not have substantive maintenance work.The actual use of battery was lower than 80% failure conditions with regard to the recurring structure capacity about 3 years, and present many units adopt the measure of " capacity recovery " to attempt to address this problem.Facts have proved that the normal time between failures of battery that restores through capacity had only about 6～10 months.
The power department regulation will be safeguarded sealed cell, but the standard laid down by the ministries or commissions of the Central Government or the GB do not safeguarded.Therefore press for and find a method that employing is rationally safeguarded to sealed cell, prolong the actual life of sealed cell.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of online capacity maintaining method of direct current operative power source of substation storage battery is provided.
For achieving the above object, the present invention adopts following technical scheme: a kind of on-line maintenance method of accumulator capacity of direct current operative power source of substation, form by following step:
Detect: for the normal transformer station of running status, cut off AC power, independent by storage battery to the control cubicle power supply, detect the load voltage value U of battery one by one with storage battery retained storage capacity detector
F, and record, should observe the magnitude of voltage that control cubicle shows during detection continuously, be lower than the standards for safe use voltage U
ABattery should stop immediately measuring;
Change: load voltage value U
FBe lower than the standards for safe use voltage U
ABattery altering, ensure the harmony of battery capacity;
Moisturizing: the battery supplementing water under will changing adds water according to its structural capacity in the ratio of 500mL/500Ah～1500mL/500Ah behind the pole plate height again;
Charging: regulate and calibrate float charge voltage to 98.18%～101.82% of rated voltage, make the final retained storage capacity of storage battery be not less than 80% of structural capacity.
Changing between step and the watering step, retained storage capacity be not higher than the storage battery of structural capacity 60%, carrying out electronics sulphur removal equalization.
For rated voltage is the storage battery of 110V, the standards for safe use voltage U
ABeing 93V, is the storage battery of 220V for rated voltage, the standards for safe use voltage U
ABe 186V, to the 12V disjunctor battery that uses in the ups power, standards for safe use voltage U
ABe 10V.
Described electronics sulphur removal equalization is: produce impulse wave with electronic circuit, pole plate is carried out the reactivity charging, eliminate the irreversible sulfation of accumulator plate, make pole plate recover active.
Positive beneficial effect of the present invention is:
1. the on-line maintenance method of accumulator capacity of direct current operative power source of substation of the present invention can be brought significant technical benefits and economic benefit to power department, but does not increase how many expenditures.The expense of power department expenditure is new battery purchase commodity and maintenance cost now, and these two expense reality all are used to change battery substantially.When more renewing battery, superseded battery is as waste disposal, the fund filling battery acquisition expenses of recovery.In the battery of scrapping, statistics shows that nearly 10～15% battery is real dead battery, and all the other batteries still can use through technical operation, but useless by wrong report now.Change fund flow direction the useless capital loss that causes of wrong report, is used for paying the online capacity maintenance cost of battery, just can carry out maintenance work substantially.By adopting the on-line maintenance method of accumulator capacity of direct current operative power source of substation of the present invention,, just quantity is upgraded in the buying of battery and be compressed to about 10～15% owing to avoided wrong report useless.By reasonable maintenance, the sulfuration damage no longer takes place in battery, and the recovery expense has not just taken place yet, and power department has also obtained technology and economic two incomes thus.
2. adopt the on-line maintenance method of accumulator capacity of direct current operative power source of substation of the present invention, irreversible sulfate damage no longer takes place in transformer station's storage battery, and this just prevents and avoided the degree of depth damage of storage battery.Battery is carried out the result that overall process is safeguarded continuously, can guarantee that cell safety reaches more than 8 years service time, standards for safe use is that structural capacity is not less than 80%.
3. adopt the on-line maintenance method of accumulator capacity of direct current operative power source of substation of the present invention, when preparing to change battery pack in batch, it can confirm rapidly that the wherein real battery that lost efficacy has only about 10～15%; When the battery that prepare to use through " the capacity activation is restored ",, might make those single batteries that direct current operative power source lost efficacy though that it can reject the discharge examination capacity easily is qualified.
4. the on-line maintenance method of accumulator capacity of direct current operative power source of substation of the present invention concerning country, has been saved the resource and the energy; Concerning power department, acquisition technology and economic two income.
