The earliest use of ordinary lead-acid battery overload capacity is low, and it is easy to produce acid corrosion; after the 1980s, it gradually be replaced by cadmium-nickel battery, although it has high reliability, small voltage drop, high pressure resistance, discharge The voltage is stable, the discharge magnification is high, and the life is long, but there is also a low battery voltage, large use, and the maintenance work is relatively large and cumbersome.The battery has an independent operating power supply, which has high reliability, so it is widely used in the substation and power plants. The valve-controlled battery has the advantages of explosion-proof safety, small number of quantities, high voltage, and convenient maintenance.
Due to the valve-controlled battery structure, the internal retention of the battery is retained to ensure that the above reaction cycle is carried out, and at the same time, the precipitation of the negative electrode hydrogen is also suppressed, and the consumption of the moisture in the battery can be sealed.
The following is a problem that the valve-controlled battery should pay attention to in use and maintenance.
- When maintaining the battery, the operator face should not be positive to the top of the battery, should maintain a certain angle or distance.
- During the operation of the battery, the connection wire should be checked once every six months, whether the bolt is loose or corroded, and loose bolts must be tightened in time (the torque of the bolt and the nut is about 11n.·m), the joint of corrosion contamination should be cleaned in time. During the charge and discharge process, if the connection strip is heated or the pressure drop is greater than 10 mV, the connection strip contact portion should be worn with sandpaper or the like.
Be——The battery should be placed in a place where ventilation, dry, away from the heat source and is not easy to generate sparks, and the safety distance is 0.5m or more. In the ambient temperature of 25 ¡ã C to 0 ¡ã C, each drop of 1 ¡ã C, the discharge capacity is about 1%, so the battery is preferably operated in an environment at 15 ¡ã C to 20 ¡ã C.
Be——To make the battery have a longer service life, use a good performance of automatic steady limit charging equipment. When the load changes within the normal range, the charging device should reach±2% of the voltage regulation accuracy can meet the requirements specified in the battery manual. Do not stop floating during non-working periods for floating battles.
Be——The newly installed or overhaulped valve-type battery pack should be checked to discharge experiments every 2 to 3 years, and the 6-year-procureable battery is running. experiment. If the battery pack capacity is not more than 80% of the rated capacity of 80%, it is considered to be replaced by the end of the rated capacity.
- After the battery is discharged, the constant current limit charging when the battery is charged.→Constant voltage charging→The charging regular of floating charge is preferably allowed to use a high frequency switching power supply type charging device for intelligent management of batteries at any Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
