What is ups battery
1. Focus on the protection of computers that store important information. Since each computer may suddenly lose power due to unstable power supply voltage or other reasons, this sudden power failure may be a common occurrence for ordinary computers, but if it is stored for those For computers with important information, sudden power failures can cause immeasurable losses to users. Therefore, from the point of view of the practical value of protection, users should only protect the power of those few important computers in order to make the UPS power supply worthwhile.
2. Select the appropriate UPS according to the protection object. If the UPS power supply is purchased to protect the ordinary computer with important information, you must ensure that the UPS can provide a protection voltage less than 300V, so that when the utility power fails, the UPS can instantly complete the process of switching to the backup power supply. The computer can still run smoothly in the event of a short power outage, without data loss and system shutdown. In the case of a long power supply interruption, the UPS equipment can start the power management software to achieve a safe computer system shutdown process, and also ensure data integrity; thus the UPS not only protects the PC hardware, but also protects the data within the hardware. If the optional UPS is to protect the network server, the optional UPS has the functions of preventing surge voltage and rechargeable battery, and also has the function of preventing data line surge to ensure that the UPS is powered off in the mains grid. In the case of full load operation for at least 5 minutes, to avoid network switching equipment from the mains interference, and the server UPS preferably has intelligent battery management.
3. The UPS cannot be operated for a long time according to the rated power. In the eyes of many people, to fully utilize the power of the UPS, the UPS should always be in the rated power state. If this is correct, if the UPS is running at full load for a long time, the service life of the UPS may be greatly shortened. The principle of UPS should be to let the UPS use the most needed place, instead of connecting some equipment that does not need power protection at all, so that it can only increase the operating load of the UPS, so that the UPS power is unknown. I don’t feel "old dead." The correct approach is to properly control the connected load of the UPS power supply to ensure that the load of the UPS does not exceed 85% of its rated power, which means that the user can properly maintain several interfaces behind the UPS power control cabinet. Of course, there is no need for the UPS power supply to operate excessively at low load, so that the UPS power supply will lose the purchase value.
4. Standby UPS is not suitable for use on equipment that is sensitive to power. The backup UPS is usually in the state of battery charging. When the power is cut off, the inverter switches to the working state urgently, and converts the DC power provided by the battery into a stable AC output. However, this UPS has a switching time problem, so it is not suitable for the power supply. Sensitive device protection. Because although this UPS switching time is very short, power sensitive devices, such as some devices with very high control accuracy, require not only the power supply voltage to be sustained, but also stable. Once the power supply has slight fluctuations, its working state Great changes can happen.
5. Make sure that the power distribution cabinet connected to the UPS is using an air switch. In order to ensure the safe use of the UPS power supply, we must also pay attention to the use of the power distribution cabinet connected to the UPS, because if the power distribution cabinet connected to the UPS uses a common old-style knife switch, this switch is connected to or disconnected from the power supply. In the moment, there is a phenomenon of arcing, which will generate sudden tip currents and cause additional interference to the mains grid. If the power distribution cabinet adopts a new type of air switch, the arc-extinguishing function of the switch can be used to avoid arcing. Phenomenon to ensure the stability of the utility grid. In addition, the old switch is slow in current response due to the use of a fuse, so that it is not easy to cut off the power in time when a short circuit or other special situation is encountered.
6. The UPS power supply for protecting the server preferably has an intelligent management function. Since the server is the core of a network, all the important information in the network is stored in the server. Once the server has any accidents, the whole network may be in a state of paralysis, which shows how important it is to protect the server. In order to respond to any abnormality of the server in time, this requires that the UPS connected to the server has some intelligent management functions, such as automatic management and adjustment of the power supply of the server, or when the power supply encounters a sudden failure. The UPS can automatically shut down the operating system of the server and turn off its power. In addition, the intelligent function of the UPS also includes transmitting information about the server to the operating system or network administrator through the network, so that the server administrator can perform remote control and management immediately.
7. Let the battery work in the right environment. In the eyes of ordinary people, the UPS power supply is the sealed lead-acid battery cabinet; in fact, the lead-acid battery is only the power supply part of the UPS power supply, and the other part is the power control cabinet. For the power control part, we don't need much maintenance, but what maintenance work can we do for the lead-acid batteries sealed in the cabinet? In fact, the most important thing for the maintenance work of the battery is to make the battery work properly. In the environment, because the battery has higher requirements on the temperature of the working environment, the temperature is suitable for the battery to exert the best potential. On the contrary, the function of the battery can not be used well, and the service life of the battery is prolonged. To this end, we try to ensure that the operating temperature of the battery is around 25 °C. If the temperature is too high, the battery life will be shortened. If the temperature is too low, the UPS will not reach the nominal delay. In addition, when assembling the battery, be careful not to mix the batteries with different installation hours and different factory brands, which will greatly reduce the actual use of the UPS power supply.
