2, focusing on the quality of the installation. The quality of installation, including storage, installation, capacity, and many other aspects of the experiment, so the transportation and storage must be careful not to collide during the installation process should pay attention tandem with the Dell Inspiron 1420 battery of the match between the battery carefully very unequal stakes race. In the extreme tightening of the stack, the force can neither too large nor too small. Will a bunch of very large forces in all loops of copper excess, too small, it follows from the convergence of poor contact with the fuel cell to install the best use of a convoy of supplied power was the key, or in accordance with manufacturers to provide a reference kilogram force, using the appropriate key kg. The facility should also be attentive to DC battery and the screen in each group between the battery positive and cathode, anode and cathode of the length of the line as much as possible to maintain the high discharge current battery, a balance between the two groups.
Must be put into service until the electricity surcharge. The installation of sealed batteries generally dates from the date of manufacture of a longer time, sealing the battery after long-term self-discharge, the significant loss of capacity must be based on a simple float hard to restore its ability origin. In addition, only difference in the size of the battery discharge, resulting in the proportion of the voltage across the battery so there is no balance, is not set service to complement the first, individual cells will be further expanded in the back of the hp PB992A battery or the phenomenon of anti-pole.
3, improving the quality of maintenance
The maintenance staff must fully understand the valve regulated lead acid batteries in the product specification of the requirements under the principle of engaging in maintenance work, improving the quality of maintenance.
⑴ temperature of the battery capacity discharge, life, self-discharge, greater shock resistance and other aspects, although the supply of power switching function with temperature compensation, but its sensitivity and magnitude, after all limited. Therefore, the hall of the battery must be installed in air conditioning and temperature control between 22 ℃ ~ 25 ℃. This not only extends battery life, but also has the best battery capacity.
⑵ once a month should be checked whether the charging device operating parameters under qualified, with or without alarm fault. In any case, the sony VGP-BPS2A battery float voltage must not exceed the manufacturer for a floating charge given, and by changes in temperature, at any time using the factor of voltage regulation of ± 3 mV / ℃ to adjust values of float voltage.
⑶ right valve view of the unbalanced nature of the impact of lead acid batteries must be used to float the lower limit for the floating voltage.
⑷ imbalance in the battery than the depth of discharge after the battery is running in one quarter, should be a balanced approach to supplement the battery. In the equalizing charge should pay attention to changes in environmental temperature and the temperature of the environment, but will decrease the value of balanced voltage settings. For example, if the temperature increases 1 ℃, then the equilibrium value of the charging voltage is necessary to reduce the 3mV.
⑸ try to use free pulse of the way “backwards battery” to charge the batteries to promote the activation and recovery.
⑹ careful maintenance, the valve regulated toshiba PA3191U-4BRS battery before going into production should be carefully recorded each voltage single cell and data on the internal resistance as raw data kept on file for six months for each subsequent performance is required to run the data compare with the original data, if the abnormal situation should be handled promptly.
⑺ must be measured once a month, the battery voltage and the voltage across monomer. Batteries sealed terminal measuring voltage can be in the floating state should be conducted in the state of discharge. Sealed battery voltage terminal to reflect the good working conditions 10 is an important parameter. Floating state, the measurement terminals of the battery voltage, due to the presence of the applied voltage, measure the voltage across the battery could easily lead to false. Although some anti-pole or open-circuit the battery can also measure the normal values (in fact, the applied voltage in the battery caused by the voltage difference at both ends), which is easily lost in the exchange sub electrical substations and power plants caused by the accident. Regularly discharge the voltage across the apple A1012 battery under the state measurement, this is completely avoided.
⑻ To ensure that the battery has sufficient capacity to conduct an annual test of the resilience (that is the great burden of Da-Fang), so that activation of the material inside activation of the battery to restore the battery capacity. The main method is to charge the battery from the machine into the battery pack controlled both ends of the load, while the current resurgence of the battery 0.1 times the rated capacity of each half-hour recording time voltage of the battery until the battery voltage to 1.8V / only (for 2V / only a single battery) or 10.8 V / only (for 12V / only a single battery) after the cessation of discharge, and save time. Put it aside, at 2am, then the same size of current on the battery to charge at constant current, the battery voltage up to 2.35V / only or 14.1V / just to keep the voltage on the load Battery 8am balance is a constant voltage of 2.25V voltage read / only or 13.5 V / only to perform a floating charge. The above method, you can make 80% of battery capacity due to the inclusion of the safe operation of the battery capacity can also be released for 30% to 50%, which should be verified and the discharge curve of the Aspire 3000 battery.
⑼ VRLA battery life is running in the 1 / 2, the need to appropriately increase the frequency of testing, particularly for single 12V battery to increase the test. If the battery internal resistance of a sudden increase in value or voltage instability measure (in particular, to two decimal places) should immediately as a “behind the battery” to carry out an activation treatment.
⑽ on a regular basis to check whether the onset of valve regulated lead acid batteries deformation and abnormal heat, carefully check the safety valves have been around the stain spray in order to determine if the valve Security tightened or damaged.
⑾ Battery capacity alone is not enough, because in need of replacement, only once replaced all, not just performance alone is not enough to replace the sony VGP-BPS5 battery down, otherwise they will be affected by imbalances in the internal resistance of batteries all the band playing drums and shorten the entire group of living cells.
⑿ not only the increase or decrease the number of single charge of battery cells, resulting in the ability of imbalance single battery charge and inconsistency, which reduces battery life. If the whole group as part of the stack to feed others, or the charge is not together with the discharge stack.
⒀ use of technical means to strengthen surveillance, such as the use of batteries on monitoring devices online, real-time monitoring of battery condition of employment. Pairs of substations unattended must also be sent to the central monitoring of information collected, the timely warning unusual processed quickly.
In short, we must attach importance to the maintenance of valve-regulated lead acid batteries, according to the different characteristics of valve regulated lead acid batteries, valve lead acid batteries, which affect a major factor in life and constantly improve the level of maintenance to achieve the goal of improving life in order to improve the sub-stations, power plants and the safe operation of the station level communication.
