According to different application fields, UPS can be divided into two categories: Industrial UPS and commercial UPS; industrial grade UPS is mainly used in harsh environmental conditions, such as dust, pests, high temperature conditions and earthquake areas, to protect important production processes and systems, prevent economic losses and personal safety.
Industrial UPS is a professional designed personalized UPS, which is completely customized according to the needs of users; each industrial UPS must go through strict industrial production process to ensure that it fully meets the technical requirements of customers.
The unique input and output transformer of industrial UPS will not only protect current from input interference, but also improve the quality of final power output. For example, in the harsh industrial environment such as petrochemical industry, the quality of the output power supply will directly affect the safety and production capacity of the whole plant equipment and personnel.
Industrial UPS has strong overload capacity. When the equipment is overloaded, the possibility of UPS switching to bypass operation is very small because of its strong overload capacity. This will greatly increase the security of the system. When switching to bypass operation, it means that the load is no longer supplied by inverter or battery.

This paper introduces the characteristics of UPS power supply and the application of UPS. As a telecom operator, base station equipment is the main data platform for operation information. It carries huge data services, and power supply system also carries huge pressure of power supply security. Power supply is the foundation, monitoring is the means, any link failure will bring loss to operators. Therefore, creating a safe and reliable power supply system, ensuring the reliability and security of data network, as well as network coverage and comprehensiveness, is the primary problem to be solved by all operators. The features and application of telecom UPS power supply are introduced below.
Features of UPS power supply for telecom
The UPS power supply system for telecom realizes full front maintenance and operation, and has enough operation and maintenance space, which can easily replace the power module. The modular UPS does not need expert maintenance, and ordinary engineers can operate and maintain the power module. The power module can be replaced by two people within 5 minutes by online hot swap. Compared with the tower UPS complex original professional complex operation and maintenance, save a lot of operation and maintenance time and cost.
With the reorganization of telecom industry and the commercialization of 5g, the domestic telecom UPS power supply market has been more rapid development. Under the background of energy saving and emission reduction, energy saving, power saving and environmental protection has been paid more and more attention by the telecom industry, and the telecom UPS power supply, which ensures the reliable and safe operation of telecom equipment power supply, is no exception.
At present, as far as the telecom network is concerned, the use of modular UPS power supply is more and more common. The scope of power supply objects mainly involves computer terminals, servers, routers, switches, displays, disk storage arrays, minicomputers, etc. The way of power supply has also evolved from small UPS decentralized power supply to large telecom UPS power supply centralized power supply. In order to ensure the reliability of power supply, N + 1 parallel hot standby system is even used.
In the installation of UPS power supply and battery space is limited, it is necessary for UPS power supply manufacturers to improve the space utilization rate of equipment installation.
In case of earthquake and fire emergency, the remote control quick shutdown function without end or near end can be provided to prevent serious damage in case of emergency.

A good installation position is very important. The place where UPS is placed must have good ventilation effect, away from water, combustible gas and corrosive agent, and the ambient temperature should be kept between 0 ~ 40 ℃. If the UPS is disassembled and used at low temperature, there may be water droplets condensation. Once the ambient temperature exceeds 25 degrees, the battery life will be shortened by half for every 10 degrees increase. At present, the storage batteries used in ups are generally maintenance free sealed lead-acid batteries, and the design life is generally 5 years.
The UPS power supply should not be placed on the side, and the air inlet and outlet holes should be kept unobstructed. When the load is connected with the UPS power supply, the load must be turned off first, then the wiring is connected, and then the load is opened one by one. It is strictly forbidden to connect the electric load, copier and other inductive loads into the ups to avoid injury. When the UPS is connected to a special socket with over-current protection device, the power socket used should be connected to the protective grounding end; whether the input power line is inserted into the utility socket or not, the ups output may be charged. In order to make UPS without output, it is necessary to turn off the switch first, and then cancel the power supply.
After the new UPS power supply is purchased, the ups should be inserted into the 220 V municipal power grid for at least 12 hours to ensure that the battery is fully charged. Otherwise, the actual usable capacity of the battery will be much lower than the nominal capacity of the battery. If UPS is not used for a long time. The ups should be started for 24 hours every 2-3 months to make it fully charged, and the UPS power supply should be kept in the inverter working state for 2-3 minutes to ensure the normal life of the battery. Once the UPS power supply is connected to the mains power supply, it starts to charge the battery pack. Press the power on key for more than 1 second to start the inverter.
The excessive discharge and long-term open circuit idle of the battery can increase the internal resistance of the battery and deteriorate the charging and discharging performance. For long-term idle UPS power supply, before restarting, make the UPS power supply use the charging circuit in the machine to charge for 12 hours, and then connect the load. For the backup UPS power supply, it is better to keep the UPS power in the inverter state for 2-3 minutes every other month to activate the storage battery. In addition, it is also necessary to strictly control the charging current of the battery to not exceed the maximum allowable charging current of the battery. Because excessive charging current will shorten the service life of the battery.
The correct startup and shutdown sequence should be to turn on the ups to supply power to it, and then turn on each load, so as to avoid the damage to UPS caused by the instantaneous current impact when starting. The sequence of power-off is just the opposite. Each load should be shut down first and then the ups should be turned off. When the power supply is interrupted by UPS, you should save your own data and data as soon as possible, and then turn off the computer. Otherwise, the use of UPS power supply may cause excessive discharge of UPS, thus shortening the service life of ups.
When using UPS, the size of the load should be calculated to avoid the load being too large or too small. Too large load will make ups work in overload state for a long time, so as to shorten the service life of ups. If the load is too small, the working circuit of ups will work in abnormal state for a long time, which is also harmful to UPS. Reasonable load should be controlled between 50% and 80%. Practice has proved that the best output load control of UPS is about 60%, and the reliability is the best. In case of overload or inverter failure, ups will switch to bypass mode. At this time, UPS has no backup function, and the power supply for load is directly supplied by power system.

1.Use of AC voltage regulator
After using UPS power supply, there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load.
2.Battery balanced charging skills
At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is 10.5 V; for 24 V batteries, the final discharge voltage is 21 V; for 96 V batteries, the discharge calibration voltage is 85 v. The battery is not charged in time after discharge; the battery is idle for a long time. When the power supply is interrupted, the battery with continuous floating charge will release nearly half of its capacity.
3.Do not use diesel generators
UPS should not be powered by diesel generator because its frequency is often unstable, which affects the normal operation of ups.
4.Pay attention to the safe operation of operators
When connecting the output power supply to UPS, attention should also be paid to safety. Since the output voltage and current of ups are relatively large, it is necessary to pay attention to safety when connecting the output power supply to prevent the occurrence of electric shock accidents.
When replacing the battery, turn off the UPS power supply and disconnect from the mains power supply. Use a screwdriver with insulated handle. Do not put tools or other metal objects on the battery. When connecting the battery cable, it is normal to have small sparks at the connector, which will not harm personal safety and UPS power supply. Do not short circuit or reverse connect the positive and negative electrodes of the battery. When replacing the battery, it is not suitable to replace it partly, but to replace it as a whole. In addition, it is forbidden to use batteries with different amperage and different brands.
5.Real time monitoring
At present, all intelligent UPS have operability characteristics such as communication with microcomputer and program control. When the corresponding software is installed on the microcomputer and connected to UPS through serial / parallel port, the program can be used to communicate with ups. Generally, it has the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Then, the UPS is connected to the computer through the special serial port control cable, and then through RS232 and RS485 protocol communication, the ups can automatically shut down when there is no mains power input and the power is low. It can monitor multiple UPS connected to multiple serial ports at the same time. Among them, through RS232 protocol, a serial port can only connect one UPS, through RS485 protocol, a serial port can connect 256 ups at most.
