摘要
随着云计算等行业快速发展,新建数据中心数量不断增加,保证数据中心供配电系统的可靠性被更加重视。本文介绍了数据中心所采用的3种不同形式的逐级投切方案,通过对变压器进行延时分合闸,错开多台变压器同时合闸所产生的对于上级线路或者油机的涌流冲击,利用综合保护装置的来电自合闸功能实现逐级投切的方案最优,为同类数据中心的建设和改造提供了参考依据。
With the rapid development of cloud computing and other industries,the number of new data centers is increasing,and ensuring the reliability of data center power supply and distribution system is paid more attention.This paper introduces three different types of step-switching schemes.The inrush current generated by the simultaneous switching of multiple transformers is impinged on the upper line or the oil engine through the delayed switching and closing of transformers.It provides a reference for the construction and transformation of similar data centers.
