电子计算机是一个复杂的电子系统,价格比较昂贵,其性能受到工作环境的影响。为了电子计算机运行的可靠与安全,并延长其使用寿命,通过我们几年来的工作实践体会到,作为一般用户而言,应该注意以下几个问题: (一)电源中外计算机专家都说:“电源是计算机的心脏”,这是一种形象而生动的提法。电源为计算机信息的产生、贮存、加工和传送提供足够的电能。电源中断,计算机的生命就立即停止。电源又是计算机的屏障。交流电网电压
Electronic computers are complex electronic systems that are expensive and their performance is affected by the working environment. In order to ensure the reliability and security of electronic computers and extend their service life, we have realized through our work experience for several years that, as a general user, the following issues should be noted: (1) Power supply computer experts both outside and outside say: “Power supply It is the heart of the computer.” This is an image and vivid formulation. The power supply provides enough power for the generation, storage, processing, and transmission of computer information. When the power supply is interrupted, the computer’s life stops immediately. Power is again the computer’s barrier. AC grid voltage
