自动转换开关电器的中性线重叠结构改进设计

Improved Design of Neutral Line Overlapping Structure of Automatic Transfer Switching Equipment

介绍了中性线重叠原理,通过中性线重叠时间设计,阐述了中性线重叠结构的改进,可有效解决转换过程中,负载三相不平衡时断零产生的零地漂移电压和瞬态涌压,以提高电信和数据中心的服务器设备用电安全。

The principle of neutral line overlapping and the improvement of the neutral overlapping structure are introduced.Through the neutral line overlapping time design,the zero-ground drift voltage and transient surge caused by the zero-breaking of the load when the three-phase load is unbalanced during the conversion process can be effectively solved,so as to improve the power safety of server equipment in telecommunications and data centers.
