　　Technical characteristics and parameters of modular power dedicated UPS power supply. The modular power UPS power supply system should adopt a structural design that complies with industry standards, has low space requirements, uses modules as installation, expansion, and maintenance units, has the characteristics of online expansion and convenient maintenance, and maximizes the reliability, availability, and Safety, providing users with the most perfect power solution.

　　Technical characteristics of modular power dedicated UPS power supply

　　Modular power UPS power supply is a UPS specially developed according to the characteristics and requirements of the power system. The UPS module adopts a live plug-in and pull-out mode. The modularity of the UPS makes the backup method very simple, and can quickly and efficiently perform on-site replacement and maintenance. At the same time, this structural model greatly improves the reliability of the UPS system.

　　The modular UPS power supply system adopts the latest parallel technology and N+X redundant structure design to provide truly high-reliability power supply for various industries. It also has the features of ordinary UPS power supplies such as online hot-swappable, convenient and fast maintenance, and easy expansion. No features. The UPS module has a single capacity of 2KVA/2.5KVA/3KVA and can be used in parallel. Up to 20 modules can be connected in parallel. Users can flexibly configure modular UPS power systems with different capacities from 2KVA to 60KVA according to their needs. If any UPS module fails, it will automatically stop working, and other modules will automatically share its load.

　　Electric power-specific UPS power supplies have a certain range for the machines used. Not every model can be applied to the equipment used by users. Electric power UPS power supplies are specially designed for power plants, substations and other power industries. They will have their own DC panels of 220V, 110V DC inverter into AC220V/380V50Hz pure sine wave output.

　　Characteristics of special UPS power supply for electricity

　　The 1+1 redundant parallel working mode allows the power supply system to add a safety lock to meet the extreme needs of power industry users for UPS high reliability indicators;

　　Making full use of the 220V/110V large-capacity battery packs in the power industry can maximize the backup time of the UPS and save the installation space and initial investment of the battery pack;

　　Optional bypass isolation transformer can achieve complete isolation between input and output, and ensure that the output zero-ground voltage is <1V;

　　The rich dry contact monitoring signals can be incorporated into the power plant's own DCS monitoring system; if problems occur, they can be reported in time to facilitate real-time monitoring of the UPS power supply by the personnel on duty.

　　Advantages of modular UPS power supply

　　1. The failure of a single module does not affect the normal operation of the system, and there is no need to shut down and wait for repair, so users will not suffer losses due to UPS module failure;

　　2. Technicians do not need to check the fault point on site and can directly replace the module. If the user has spare parts, he or she can maintain it by himself;

　　3. The average repair time is reduced from 8 hours to 5 minutes in online mode;

　　4. The modular UPS power supply adopts multi-level distributed control theory. The power module, monitoring module and static switch module can all be plugged and unplugged online without affecting each other;

　　5. With multiple working systems, the modular UPS product has multiple formats to choose from, is easy to operate, and can realize multiple incoming and outgoing methods;

　　6. Energy saving and environmental protection: It has little pollution to the power grid, and technologies such as high efficiency and module dormancy reduce energy waste.

　　Technical parameters of modular UPS power supply

　　The technical parameters of modular UPS power supply mainly include: rated capacity, input voltage range, input power factor, output voltage, output power factor, battery voltage, and overall machine efficiency.

　　Input characteristics:

　　1. Input voltage range A wide input voltage range can reduce the chance of battery discharge and extend battery life.

　　2. The input power factor is low, the input reactive power is large, and harmonic current pollutes the power grid and affects other equipment.

　　3. Allowable range of main power frequency.

　　4. Input the harmonic component of the current. (PFC, 6/12 pulse transformer)

　　Output characteristics:

　　1. Static stability. 1% for large and 2% for small and medium-sized.

　　2. Output transient characteristics. 5% for large and 8% for small and medium.

　　3. Output overload capability. (For example: overload 125% 5MIN; 150S)

　　4. Output power factor. (0.8, 0.9, 1)

　　5. Output voltage harmonic distortion. Typically within 3%.

　　Centralized power supply method:

　　Advantages: It can realize equipotential control of network equipment resources and reduce the transmission bit error rate.

　　Disadvantages: Large initial investment, single machine failure has a great impact.

　　Decentralized power supply method:

　　Advantages: The scheme layout is flexible and the impact of failure is small.

　　Disadvantages: If the entire equipment cannot be kept in the same ground line, it may easily cause a fault.
