某医院智能配电系统设计

Design of Intelligent Distribution System in a Hospital

随着我国科学技术发展和现代医疗设备与设施的不断进步,现代医院对配电系统的智能化需求也越来越强烈;文章从某医配电系统的智能化需求出发,重点地分析医院手术室的系统接地形式及供配电系统,以及对手术室、病房照明系统进行了智能化的设计,充分考虑了医院智能化配电系统的安全性与可靠性,供电电源自动恢复时间控制在了0.5秒以内,手术室供配电系统每个配电箱的容量均在8到10 kVA,两个手术室共用一个IT系统的情况下,设备的正常漏电流控制在了10μA以下,设备的故障电流控制在了50μA以下,医疗电子设备采用公用接地,接地电阻控制在了4Ω以下,基本符合《JGJ312-2013医疗建筑电气设计规范》的相关要求;希望通过研究为医院智能配电系统的设计提供有益的参考与借鉴。

With the development of science and technology in China and the continuous progress of modern medical equipment and facilities,the intelligent demand for power distribution system in modern hospitals is becoming more and more intense.Starting from the intelligent demand of a medical power distribution system,this paper focuses on the intelligent design of the system grounding form and power supply and distribution system of the operating room of the hospital,as well as the lighting system of the operating room and the ward.The safety and reliability of the intelligent power distribution system of the hospital are fully considered.The automatic recovery time of the power supply is controlled within 0.5 seconds,and each power distribution system of the operating room is controlled within 0.5 seconds.The capacity of the boxes is 8-10 kVA.When two operating rooms share an IT system,the normal leakage current of the equipment is controlled below 10μA,the fault current of the equipment is controlled below 50μA,the medical electronic equipment is grounded by public,and the grounding resistance is controlled below 4Ω.The basic requirements of JGJ312-2013 code for electrical design of medical buildings are met.It is hoped that the research in this paper can provide useful reference for the design of intelligent distribution system in hospital.
