UPS作为备用电源设备,在金融、通信及工业领域的数据信息中心和自动化控制生产线方面得到了广泛的应用,对保障供电安全、可靠以及电能质量发挥了积极的作用。在UPS实际应用中,机房配电系统设计、UPS供电系统设计(包括接地设计、供电方式、接地方式选择及零地电压处理等)、绿色高效机房建设、机房设计标准以及UPS选型和蓄电池维护等问题受到业内设计、技术人员的普遍关注。本期栏目将关注UPS谐波治理、直流高压UPS供电系统电压等级的确定、电机类设备不间断电源技术探讨、工频UPS和高频UPS在结构和工作原理上的区别等问题,继续邀请UPS专家、用户和UPS厂商技术人员进行交流、探讨。相信通过本期嘉宾的精彩发言能让您对上述问题有更深刻的认识和了解,同时欢迎感兴趣的读者积极参与,谢谢! As a backup power supply, UPS has been widely used in data information centers and automation control production lines in the financial, communications and industrial fields, and has played an active role in ensuring power supply safety, reliability and power quality. In the practical application of the UPS, the design of the power distribution system, the design of the UPS power supply system (including the grounding design, the power supply mode, the selection of grounding modes and the zero voltage treatment), the construction of a green and efficient engine room, the engine room design standard, UPS selection and battery maintenance And other issues by the industry design, technical staff of the general concern. This column will focus on UPS harmonic control, DC high voltage UPS power supply system to determine the voltage level, motor type equipment uninterruptible power supply technology, frequency UPS and high frequency UPS in the structure and working principle of the difference, and continue to invite UPS Experts, users and UPS manufacturers technical staff to exchange and discuss. I believe that through this distinguished guests speech allows you to have a more profound understanding of the above issues, and welcomes the active participation of interested readers, thank you!
