The invention discloses a periodical automatic discharging apparatus for a storage battery pack, and mainly solves the problem that the battery capacity is decreased when the storage battery is under a floating charge state for a long time. The periodical automatic discharging apparatus mainly comprises three parts, including a timing apparatus, a discharging control apparatus and a load discharging resistor; the discharging control apparatus is controlled to discharge at a certain time by a combination of a timer DS and a counter JS; and the discharging control apparatus automatically switches charging and discharging according to the magnitude of the voltage of the storage battery through the matching of a direct current voltage relay S, a main relay KM and an auxiliary relay KM2. The periodical automatic discharging apparatus has a good maintenance effect on the storage battery; extra manual maintenance is not required; and in addition, the periodical automatic discharging apparatus is safe, convenient and reliable.
Description
Technical field
The present invention relates to electricity field, the device of the regular automatic discharging of a kind of accumulator battery.
Background technology
In electric substation's maintenance process, maintenance employee finds that the battery group capacity in DC source is not enough, does not reaches design requirement.Originally the accumulator battery of about 5 years projected life only employs 2 years in electric substation, capacity declines significant need and changes, find during looking for reason at inspection information, chief reason is exactly the problem in terms of the use and maintenance of accumulator, accumulator is the most on the shelf or makes accumulator be in floating charge state for a long time and not discharge, substantial amounts of lead sulfate in battery can be caused to be adsorbed onto the cathode surface of battery, form " sulfation " of cell cathode plate, owing to lead sulfate itself is a kind of insulator, battery will be filled by its formation, discharge performance produces deleterious effect.Therefore the sulfate formed on minus plate is the most, and the internal resistance of battery is the biggest, and the charging-discharging performances of battery is the poorest, and its service life is the shortest, at present.Accumulator great majority are all under long-term floating charging state, only charging, do not discharge, this duty is the most unreasonable, form " sulfation " of cell cathode plate, make accumulator internal resistance be increased dramatically, make the actual capacity (A.h) of accumulator well below its normal capacity, thus the actual backup time causing accumulator can be provided by is greatly shortened, reduce its service life.So, every discharge and recharge in 34 months once, electric discharge rated capacity 20% 30% effect activates pole plate to accumulator exactly, in order to avoid long-term floating charging causes pole plate to soften.Therefore the automatically periodically electric discharge device that we design and produce, it is achieved maintenance work that the timing of accumulator battery is automatically discharged, it is to avoid accumulator long-term work, at floating charge state, causes accumulator plate generation sulfation reaction.
Summary of the invention
