摘　　要：襄阳图书馆项目采用两用一备的冷水机组方案,现场调试时出现第二台冷水机组起动过程中变压器低压侧进线开关跳闸的问题,从原供配电系统方案、负荷计算、电机起动方面分析,通过调整负荷分配,解决了现场问题,并对临时解决方案进行优化设计。The dual-use and one-standby water chiller solution was adopted in Xiangyang Library Project in Hubei.During on-site commissioning,the tripping problem of transformer low voltage side inlet switch during the startup of the second chiller is analyzed,from the three aspects of the original power supply and distribution system plan,load calculation and motor starting.The on-site problem was solved by adjusting load distribution.The temporary solution is optimized and designed.
