UPS作为保证电子信息系统、工业控制系统供电安全的重要设备,是目前应用最广泛的备用电源产品。UPS的高频化趋势一直是UPS领域一个备受争议的话题。随着高频UPS产品的大量生产和广泛应用,输出隔离变压器的设置、取消输出变压器是否影响高频UPS的性能以及高频UPS输出是否需要加装输出变压器等成为UPS供电系统设计人员需要面对的问题。其次,直流UPS作为一种与传统交流UPS输出方式互补的新型UPS产品,与交流UPS相比具有结构简化、效率高及成本低的优点,但其大规模应用还面临一定的问题。此外,电力专用UPS、石化专用UPS等工业专用UPS的性能特点也是工业用户想要了解的一个内容。本期栏目将邀请五位UPS电源领域的专家和UPS厂商技术人员针对上述话题以及UPS选型问题进行讨论、交流,同时欢迎感兴趣的读者能积极参与。
As an important equipment to ensure the safety of electronic information system and industrial control system, UPS is currently the most widely used backup power supply. UPS high frequency trend has been a controversial topic in the field of UPS. With the mass production and widespread use of high-frequency UPS products, the output isolation transformer settings, cancel the output transformer affect the performance of high-frequency UPS and high-frequency UPS output transformer needs to be installed to become a UPS power supply system designers need to face The problem. Secondly, as a new type of UPS complementary to traditional AC UPS, DC UPS has the advantages of simple structure, high efficiency and low cost compared with AC UPS, but its large-scale application still faces some problems. In addition, power-specific UPS, petrochemical-specific UPS and other industrial UPS performance characteristics of industrial users also want to understand a content. This column will invite five experts in the field of UPS power supply and UPS manufacturers and technical personnel to discuss and exchange questions on the above topics and UPS selection, and welcome interested readers can actively participate.
