计算机房供电系统的布线及维护

Layout and maintenance of the power supply systems in computer rooms

计算机房供电系统的负载主要有 2种:容性负载和感性负载,前一种为主要负载.现计算机主机及外设均采用偏容性负载的无工频变压器开关电源.由于容性负载对供电系统的开关、中线有特殊要求,为了保证计算机系统长期、可靠地运行以及机房的安全,本文介绍了计算机房供电系统的合理布线和维护方法.

There are two kind of loadings of the power supply systems in computer rooms such as capacitive loading and inductive loading, the former is main one. The switching power supplies of capacitive loading with no operating frequency transforner, are generally used in modern host computers and peripheral equipments, there are special requirements of the switch and midline of power supply systems. For ensuring the reliably long-term running of computer systems and the safety of the computer rooms, the reasonable layout and maintenance of the power supply systems in computer rooms were introduced.
