      Six aspects reflect the performance of Shante UPS power supply

      1. UPS mainframe should have strong adaptability to power grid environment.
      To install an UPS, the first thing to consider is its adaptability to complex grid environment, including the adaptability driven by a diesel engine. The performance indexes to be examined include the allowable range of input voltage, input power factor and the ability of bidirectional anti-jamming of UPS. When the input voltage is allowed to change in a small range, UPS will frequently enter the battery power supply state; when the input power factor is low, it means that there is a large non-linear current component in the input, which will not only destroy the environment, but also lead to the expansion of the capacity allocation of power supply equipment and transmission, and waste of power. Anti-interference performance includes the ability to suppress various interference in the power grid and the backbone of the power grid. Disturb.
      2. The adaptability of UPS to various loads
      This refers not to conventional indicators such as voltage stability, waveform distortion, frequency stability, dynamic response time, backup conversion time, but to note whether UPS can operate normally under some special load configurations. Such as strong capacitive load, impulse load, rectifier filter input load, load with the same power linear transformer input. The performance indicators to be examined are the ability with non-linear load (output power factor), the ability with periodic impulse load (break of wave crest) the ability with random impulse load (instantaneous overload or short circuit endurance and protection capacity), three-phase unbalanced load. Ability and so on.
      3. Improving the performance of batteries and strengthening the management of batteries
      As for batteries, we should pay attention to two problems: one is to select batteries with excellent performance, the other is to consider the use and management ability of UPS uninterruptible power supply for batteries. At present, some advanced UPS manufacturers have done very effective work in this area. Such as configuring charging circuit according to the physical and chemical characteristics of battery, monitoring battery charging status at any time, setting charge and discharge maintenance by software, temperature compensation for floating voltage of battery, and thermal replacement of battery under normal working conditions.
      4. Flexibility and Redundancy of System Configuration
      When the capacity of one UPS does not meet the demand, it can be connected in parallel. In order to improve the reliability, it can adopt multiple redundant configurations. In the configuration of UPS system, modular technology, multiple parallel technology, series-parallel redundancy technology, bypass maintenance technology and so on have appeared, which have obvious effects on improving the flexibility, expandability, maintainability and reliability of power supply system.
      5. Intelligence and Network Protection Capability
      Intelligent UPS and network protection is a new technology. For users, there is a process of gradually recognizing and expanding the scope of use. The following three issues should be paid attention to when selecting UPS. Firstly, the functions of software should include security shutdown system, state test recording system, UPS self-management system, and even environmental monitoring system. Second, the types of operating systems (compatibility) and operability that software can support. Thirdly, the software provided should be tested and authenticated by the relevant operating system manufacturers.
      6. Inspection of UPS Hardware System
      Hardware system is the key factor to determine the reliability of UPS mainframe operation. The contents to be inspected include the technical level and maturity of the manufacturer, production capacity and process level, the variety and quality of the selected components, the advanced and maturity of the circuit, etc. Speaking of circuit form and advanced level, under the condition that all kinds of UPS UPS uninterruptible power supply can meet the use requirements, the exact conclusion level and performance are very difficult and unhelpful, but the continuous improvement of circuit structure will inevitably bring new performance to UPS, such as interactive circuit structure, although the circuit form of each country is still different, and the maturity of the circuit is still different. Different, but they have one thing in common. They all use the principle of power compensation in AC voltage regulating circuit, which is absolutely good for improving efficiency, reducing the working intensity of inverters and improving the reliability of the whole machine.
      UPS as a protective power supply equipment, its performance parameters are of great significance and should be the focus of consideration when we choose to purchase. Wide input range of municipal voltage indicates strong utilization ability of municipal power (reducing battery discharge). The small range of output voltage and frequency indicates that it has strong ability to adjust municipal power and stable output. The waveform distortion rate is used to measure the stability of the output voltage waveform, while the voltage stability indicates the stability of the output voltage when UPS suddenly increases from zero load to full load.
      Moreover, UPS efficiency, power factor and conversion time are all important parameters to characterize the performance of UPS, which determine the protection capacity of load and the utilization rate of electricity. The better the performance, the stronger the protection capability. Overall, offline UPS has the worst protection for load, online interactive mode is slightly better, and online mode can solve almost all the common power problems. Of course, the cost increases with the performance. Therefore, when purchasing UPS, users should select different types of UPS according to the different requirements of load on power and the importance of load.
