中小型锅炉辅机采用660V供电的探讨

Discussion on 660 V Power Supply for Medium and Small Boiler Auxiliary Equipments

目前国内55~220 t/h级别的锅炉辅机通常采用10（6）k V/380 V两级供电,即风机、水泵等大于200 k W的电机采用10 k V或6 k V供电,其他小功率辅机采用380 V供电,笔者就此级别锅炉辅机采用660 V供电系统进行分析探讨,提出了660 V供电系统在中小型锅炉系统应用的可行性。

At present, 55 ~220t/h boiler auxiliary equipments generally use 10（6）KV/380 V power supply. The motor over200 KW like blower and pump use 10 k V or 6KV power supply, other low-power auxiliary equipments use 380 V. Based on it, the paper discusses the 660 V power supply system of boiler auxiliary equipments, and puts forward the reliability of the system for medium and small boiler.
