计算机室配电线路保护设计应注意的问题

同期使用率高的计算机室常会发生配电回路漏电保护器跳闸故障,严重影响了正常使用功能.其主要原因为计算机属于正常泄漏电流大的设备,在设计配电线路保护时,如果只注意线路的过负荷及短路保护,而忽略了配电线路和用电设备存在的泄漏电流对保护电器的影响,漏电保护器就可能跳闸.本文通过分析计算,提出了防止故障发生的办法.

Notice problem for computer room match the circuit protect design

It is a common problem for a track electric leakage protector to be closed down in a computer room due to multiple equipment usage at the same time. This shut down has severely affected the performance and normal operation of computers and other equipment. Computer itself has serious leakage during normal operation, so if only pay attention to the wire overload and short-circuit proof and neglect the influence of electric current leakage from computer and other appliances when designing the electric wire and wire protection, the electric leakage protector may be shut down frequently. This paper analyzes the background theories and brings a solution to prevent the power failure.
