Description
Technical field
The utility model relates to valve controlled sealed lead-acid accumulator, particularly relates to the long and narrow type valve controlled formula sealed lead acid storage battery of 12V.So-called sleeve configuration battery refers to that cell widths is that 105mm(is applicable to 19 cun of racks) and 125mm(be applicable to 21 cun of racks), the battery of its Aspect Ratio generally between 3 ~ 4.5.
Background technology
Comprehensive arrival in 3G epoch, will create new growth engines for communication backup battery industry.In the 2G epoch, machine room and base station adopt to concentrate and transmit, and the battery capacity be equipped with 2G is relatively high, based on 2V backup battery.3G, owing to adopting RU technology, makes machine room and number of base stations significantly increase, and the battery capacity requirement be equipped with is miniaturized, based on 12V backup battery.In NodeB machine room, equipment mainly comprises main equipment and corollary equipment two class, and main equipment is generally BTS wireless device etc.; Corollary equipment has transmission, air-conditioning, power supply, storage battery etc.Base station BTS wireless device, transmission equipment, power-supply device, all can normally work in 40 DEG C of situations; Common valve controlled sealed lead-acid accumulator is the highest to temperature requirement, and nominal serviceability temperature is 25 DEG C, and storage battery can obtain longer life under the environment of 25 DEG C, if long-time running temperature raises 10 DEG C, useful life about reduces half.Therefore, on the basis of computer room temperature 25 DEG C, promoting 10 DEG C ~ 15 DEG C to what have the greatest impact in base station is battery system.Outlying mountain area, outdoor type base station is more, and the feature of these base stations is, mains system is unstable or without civil power, and the ambient temperature of battery is higher, and temperature is even up to 50 DEG C.Increasing of outdoor type machine room and number of base stations, proposes higher requirement to the reliability of 12V backup battery and maintainability.
12V sleeve configuration battery in the past, with regard to structure, its pole plate adopts the form of placing vertically, and post terminal guiding is placed in equidirectional two front ends of battery, although the 12V sleeve configuration battery of this structure meets rack, installation accesses requirement with front end, also brings some problems: bulging as easy in compressing surface; Battery cycle life declines, and especially in frequent cycle application, cannot meet the requirement of its cycle performance; Lead plaster utilance is lower.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of 12V horizontal type valve controlled sealed lead-acid accumulator, badly can keep long circulation life down in rack at high temperature power utilization environment.For this reason, the utility model is by the following technical solutions:
12V horizontal type valve controlled sealed lead-acid accumulator, comprises positive pole post terminal guiding, negative pole post terminal guiding, offset pole, positive bus, negative bus-bar, pole group, battery case, it is characterized in that:
Described storage battery is a cluster with 2V, arranges the pole groups of 6 series connection altogether, and the positive/negative plate level in the group of pole is sleeping puts, and described 6 clusters foldedly in vertical direction to be established with the form of 1 × 6;
Described accumulator pole group is horizontal positioned, and positive bus, negative bus-bar in storage battery front end, and are connected in series by offset pole in front end, improves the feasibility of storage battery assembly technology;
Described battery positive voltage post terminal guiding, negative pole post terminal guiding are drawn in the upper and lower of the front end of storage battery respectively.
Described 12V horizontal type lead acid accumulator is long and narrow type valve controlled formula sealed lead acid storage battery.
Electrolyte stratification is the dominant failure mode of the early stage capacitance loss of VRLA battery, there is certain Action of Gravity Field in electrolyte itself, do not resemble at charge and discharge cycles process VRLA battery the gas produced that to charge flooded batteries and play the effect of stirring electrolyte, thus cause battery electrolyte existence lamination to a certain degree, obvious especially in high type battery, upper electrolyte concentration is low, and bottom concentration of electrolyte is high.When after electrolyte stratification, stand up for pole plate for same a slice, same electrode variable concentrations can cause surface electrical potential difference, according to formula: E=E

4), comparatively top current potential is high for pole plate bottom current potential; In addition, when the cell is discharged, because pole plate top Ohmic resistance is lower, battery top first starts electric discharge, it is lower that concentration of electrolyte compares bottom, this chemical reaction process can be formed like this: place negative plate bottom vertically and to charge depolarising to upper plates, the upper part of so every sheet pole plate is often in full charge state, and lower part is often in discharge condition.If things go on like this, thus cause battery capacity to lose, cycle life reduces, and finally causes storage battery battery failure.This problem, for sleeve configuration storage battery, particularly seriously.
The assembling pressure of VRLA battery is general comparatively large, and inside battery also exists certain air pressure, the rising of temperature, and ABS intensity is declined, and this makes battery more easily bulging occur under the high temperature conditions.Under actual 55 DEG C of floating charges test, the bulging of ABS is probably at 1.5%-2%.The bulging of ABS groove, more easily causes the increase of floating current, causes thermal runaway further.
The utility model puts scheme by the level of 1 × 6 is sleeping, the profile of storage battery is made to be suitable for forming long and narrow type valve controlled formula sealed lead acid storage battery, rack application can be applicable to, and level crouches, the pole plate layout of putting can overcome the defect standing up plate-type battery, capacity reaches standard and higher than the capacity of the long and narrow type valve controlled formula sealed lead acid storage battery of traditional 12V, badly long circulation life can be kept down at high temperature power utilization environment, solve the contradiction of capacity and cycle life, compared with the long and narrow type valve controlled formula sealed lead acid storage battery of traditional 12V, there is the cycle life more than more than 1 times.And make the pressure-bearing surface of the utility model storage battery be the side that the area of at the bottom of the top of storage battery instead of in the past storage battery is larger, therefore, add anti-bulge ability, the utility model meteorism resistent ability is more in the past stronger.And it is highly important that, battery circuit of the present utility model connects all in the front end of storage battery, make the structural configuration of storage battery simple, install more simple.
