大型医疗设备配电方式分析

Analysis of Power Distribution Mode of Large Medical Equipment

分析了大型医疗设备供电规范中供电电源应满足大型医疗设备关于电源电压及内阻的要求。根据电路理论分析,用等效电源建立模型,得出结论:在变压器容量大及干线内阻小的情况下,楼层配电室的电源质量优于小型变压器旁出口处的电源质量,配变电所供电不能简单理解为物理上的变压器旁的配电室,也可以是楼层配电室,大型医疗设备可以采用树干或混合式配电。

This paper analyzes the power supply standards of large medical equipment:power supply should meet the requirements of large medical equipment on power supply voltage and internal resistance.According to circuit theory analysis,it draws the following conclusion from our model based on equivalent power supply:under the condition of large transformer capacity and small main line internal resistance,the power quality of the floor distribution room is better than the power quality of the outlet of the small transformer.The power supply from the distribution substation cannot be simply understood as the distribution room physically next to the transformer,as it can also be the floor distribution room,that is,large medical equipment can adopt trunk or hybrid power distribution.
