Santak UPS power supply system as to comply with the development of power market demand of high-tech products, it has obvious function of power protection: when the city electricity power, uninterrupted to the load continue to supply; in city electrical instability can avoid loading suffered from the harm of under voltage, surge, and comprehensively improve the quality of power supply; when the power system (UPS) fault, to the load (especially the computer and network systems) to comprehensive protection and overload, short circuit, battery over discharge protection, provide a stable work environment for the load.
With IT system gradually moving towards centralized management, the application of enterprise to Shenzhen Santak UPS power supply protection system will be more in-depth. The application of UPS will show the change from the single machine to the redundant structure, and the reliability of the system can be changed from the availability of the system to the system, and from the simple power supply system to ensure the entire IT operation environment change and so on. With the development of information technology, electronic technology and control technology, all kinds of advanced technology has been widely used in the design and development of UPS power supply and production process, UPS technology will appear the following six major development trends.
One is intelligent
Intelligent system through the analysis of all kinds of information, in addition to complete the control function of Santak UPS corresponding to the normal operation of the power supply part, should also complete the real-time monitoring of the operation of the UPS of the important data in the circuit analysis, the various parts of the circuit is normal for workers from other functions in UPS fault; when, according to the test results, timely analysis, diagnose the fault location, and gives the processing method; according to the scene to take necessary action to protect their own emergency control, prevent the extension of the fault; complete the necessary maintenance, with the exchange of information, can be input to the computer or to obtain information from the network machine.
Two is digital
Santak power using the latest digital signal controller (DSP) to be digitized by the hall sensor parts, to achieve the 100% digital operation of Santak UPS system. A multi microprocessor redundancy system is also used to control the rectifier, inverter and internal static bypass, which is controlled by a microprocessor with independent supply of power supply, thus improving the system's digital degree and reliability.
Three is high frequency
The first generation of Santak UP power switch for silicon controlled silicon, the second generation of high-power transistors or field effect transistors, the third generation of IGBT (insulated gate bipolar transistor). High power transistor or a field effect tube switching speed by an order of magnitude higher than that of the silicon controlled, and power device IGBT current capacity and rate and than high power transistor or a field effect tube is much bigger and faster, the power conversion circuit operating frequency up to 50KHz. The improvement of the frequency of the converter circuit makes the inductance, capacitance and noise, volume and so on for the filter greatly reduced, so that the UPS efficiency, the dynamic response characteristic and the control precision are greatly improved.
Four is redundant and machine technology
Through the development of new technology, realize inside the ups module redundancy and the machine is running, without also is provided with a central control unit and load sharing, a module, automatic load transfer, maintenance can with hot swap, greatly improve the single UPS power supply reliability. Plus multiple UPS components of the system redundant operation, if a single UPS machine failure, then immediately shut down, the other UPS system will automatically assume full load, the load will not have any impact.
Five is the integration of
With the development of information technology, the application field of power protection continues to expand and continue to improve, the Shenzhen Santak UPS power supply to achieve these requirements can not be an exception, we must control the whole power system involved in the link, ups from the initial equipment protection and system protection pure backup power technology development to today's information protection, intelligent management and the whole room integrated application, its connotation has been extended to power generation, distribution, transformation, uninterrupted power, room, power equipment, power cable, a data wiring, environmental monitoring and system management has not the original meaning of UPS, UPS equipment just the core component of the system.
From the point of view of Santak UPS power supply technology, in the power output characteristics of continuous optimization based on, research on power input characteristics, electromagnetic compatibility, low harmonic pollution has become an important indicator, harmonic treatment technology and electromagnetic compatibility design can improve the power grid load characteristics, reduction of other devices *, improve the power of the source effect, the concept of green power began attention by the people. The development of electronic technology and computer technology, in addition to greatly enhance the power performance of the ups, the network management can achieve remote monitoring, digital power supply control technology make products with the custom function, intelligent design make it as highly intelligent supervision, control and adaptive devices.
From the point of view of information construction, ups from the past focus electrical performance, reliability and quality to uniform standards, specifications, modular and parallel redundancy technology and systematically consider supply, electrical equipment and links and system TCO, improve the UPS power involved the system reliability, availability, management, maintenance and scalability. Integration application for users to provide complete and effective application of power to the solution, this expansion direction to meet the needs of the information construction, but change to meet this demand, for UPS manufacturers, especially domestic manufacturers, there are still a lot of work to do.
Six is green
The harmonic current produced by all kinds of electric equipment and power supply is seriously polluted by the power grid, which is produced by various policies and regulations.
