摘　　要：在大型数据中心建设过程中,供配电系统的设计实施尤为重要。目前,国内大型数据中心通常会涉及两台或多台变压器的联络,以及变压器与柴油发电机组的联络,在此过程中,开关极数的选择会涉及到断零风险、单点故障、杂散电流以及人身安全等诸多风险因素。因此将从开关极数的选择及影响展开分析,结合实际实施案例,给出一些参考建议。In the process of large data center construction,the design of the power supply and distribution system is particularly important.The current domestic large data centers often involve two or more transformers contact,contact and transformer with the diesel generator set,in this process,the choice in the number of switch involves breaking zero risk,a single point of failure,stray current,the personal safety,and many other risk factors.This paper will analyze the selection and influence of switch poles,and give some reference suggestions based on the practical implementation cases.
