电子计算机是高固资高成本的现代化设备,随着计算机技术的普及和发展,故障维护费用也随之增加。据有关资料统计有80%的计算机故障是由电源引起的,而电源引起的计算机故障90%是由电力干扰所造成的。专家们一致建议使用不间断供电系统(Un-interrupt powersupply)简称(UPS)是解决这一问题的最佳选择。但UPS在功率、性能、结构等方面未能引起足够的重视,从而导致资源的浪费或不能为计算机设备提供可靠的供电和保护。充分了解UPS的原理、功能、选型等方面的特性,是一项急须解决的首要的问题。一、小型UPS的分类小型UPS的输出功率为0.5～3KV·A,维持供电时间5～15分钟。大致可分为在线式,后备式,其简化的工作流程图如(图一)。
Electronic computer is a high-cost high-cost modern equipment, with the popularity and development of computer technology, fault maintenance costs also will increase. According to statistics, 80% of the computer failures are caused by the power supply, and 90% of the computer-caused power failures are caused by the power interference. Experts unanimously recommended the use of uninterrupted power supply system (UPS) is the best solution to this problem. However, the UPS has not given enough attention to power, performance, structure and so on, resulting in wasted resources or unable to provide reliable power supply and protection for computer equipment. Fully understand the UPS’s principles, functions, selection and other aspects of the characteristics, is an urgent problem to be solved. First, the classification of small UPS Small UPS output power of 0.5 ~ 3KV · A, to maintain power supply time of 5 to 15 minutes. Can be broadly divided into online, backup, the simplified workflow diagram (Figure 1).
