现在大、中型微机房一般有几十台至数百余台微机,其特点是同期使用率高。一些微机房出现配电线路漏电保护断路器常跳闸故障,其原因是泄漏电流大于漏电断路器漏电动作电流。设计与安装时应考虑泄漏电流对保护电器的影响。
Now large and medium-sized computer room generally dozens to hundreds of computers, which is characterized by the same period of high usage. Some microcomputer room distribution line leakage protection circuit breaker often trip fault, the reason is that the leakage current is greater than the leakage current leakage circuit breaker. Design and installation should consider the impact of leakage current on the protection of electrical appliances.
