Description
Technical field
The present invention relates to substation equipment on-line monitoring technique field, be specifically related to a kind of online sulphur removal maintenance process of storage batteries of transformer substation based on LAN and system.
Background technology
Lead-acid accumulator has been widely used in power system the most.It is the most all to be connected in parallel on rectifying installation and be in floating charge state due to accumulator, time one is long, accumulator arise that activation goods and materials come off, the deformation of electrolyte dry-out, pole plate, pole plate corrosion and the abnormal conditions such as sulfuration, thus cause accumulator capacity to reduce and even lost efficacy, once commercial power interruption, it is most likely that lead to the major accidents such as power supply interruption.Although major part producer claim the projected life of its accumulator more than 5 years, but, many in actual use battery lifes only had for 2～3 years, inclement condition person 1～will occur that capacity is decreased obviously phenomenon after 2 years.
Typically result in a main cause of accumulator deterioration precisely due to the difference of each single battery uniformity in accumulator battery, each cell uneven (battery after electric discharge will produce " sulfuration " as do not filled in time to satisfy) when causing charging, in accumulator battery underfill one joint or a few joint cell because filling insatiable hunger and " sulfuration ", the accumulator internal resistance " vulcanized " increases, this just makes it bigger with the difference of other each batteries in group, and then " sulfuration " increases the weight of in causing battery, form vicious cycle, battery capacity cumulative bad during discharge and recharge uses is made to decline, this is the main cause that lead-acid accumulator degradation speed is accelerated.
At present, vulcanisation for storage batteries of transformer substation group is periodically to hold repair and maintenance mostly, go out and add the burden of staff outside regular maintenance on ordinary days, and manually use vulcanisation instrument, need each accumulator is detected, it is judged that could be vulcanisation after the state of cure (vulcanization) of accumulator so that the time of whole work is greatly increased, so more serious accumulator of some sulfurations can not sulphur removal in time so that the work efficiency of whole transformer station is substantially reduced.
These damage bigger accumulator and will change after the work several years.The cost expenses of this work itself is the highest but also needs a large amount of manpower.More seriously, environment can be damaged during disposing this accumulator.How to extend storage battery power supply time and service life, improve the utilization rate of resource, be our focus of attention, although not all behindhand battery can be repaired, but the benefit that the recovery technique of lead-acid accumulator is brought is mathematical.Many accumulator occur the sign of end of life prematurely due to sulfation.It practice, the battery gone out of use has 90% be available with what accumulator repairing system carried out repairing.
A kind of communication base station accumulator battery fine maintenance method of the disclosure of the invention of Publication No. 102709611A, the method comprising the steps of: the actual capacity of monitoring accumulator；The actual capacity of accumulator is compared with threshold capacity；When the actual capacity of accumulator is more than this threshold capacity, carry out online capacity of accumulator combo；And when the actual capacity of accumulator is less than or equal to this threshold capacity, carry out accumulator replacing.The invention also discloses a kind of communication base station accumulator battery backup power system, it utilizes the communication base station accumulator battery fine maintenance method of the present invention finely to safeguard accumulator, but this invention automaticity is relatively low, inapplicable for present most unmanned substation.
Network not only changes equipment type of attachment, and can be neutralized the intellectuality merging the equipment that improves by the collection of facility information.Under tectonic network interconnection environment, the present invention studies the processed of battery monitor data under network environment further, to realize the dynamic evolution of accumulator monitoring soft com-puting model.This invention takes monitoring device and maintenance, the design of maintenance interaction, interactive process gathers accumulator parameters, uses computer to carry out the advantage of data process, deterioration of battery index and residual capacity are carried out online dynamic calculation assessment.
