计算机通电冲击电流的探讨

Analysis of The Computer's Electrifying Impulse Current

由于计算机开关电源中电容因素的存在,其特殊的伏安特性会因合闸通电瞬间的电压突变而产生通电冲击电流。本文结合工程实例,分析民用建筑中计算机负载的通电冲击电流对配电系统的影响,提出相应的配电解决方案。

Because of the special voltammeter of capacitive loads existing in computer switching power supply, an electrifying mu- tation voltage will inevitably produce an electrifying impulse current. In this paper, the impact on the distribution system caused by the electrifying impulse current is analyzed with engineering examples, which generally existing in computer loads of civil build- ings. Then, appropriate solutions for power distribution are proposed.
