【节能学院】安科瑞医疗IT产品在彭世洛医院项目的设计与应用

摘要：随着电子医疗设备在医院领域的广泛应用，漏电流对病人构成的威胁也越来越大，尤其是那些生命攸关的场所，病人在手术中或麻醉状态下，各种电极、传感器直接插入人体内，微小的漏电流都有可能导致病人触电身亡。另外有些医疗设备用于维持重症病人的生命，一旦设备停电，也会对病人的生命构成威胁。因此，对于医院这一特殊场所的电气设计，应严格按照国家标准和规范要求，采用IT系统供电。本文介绍了医疗IT在彭世洛医院的应用。

Abstract: With the widespread application of electronic medical equipment in hospitals, the threat of leakage current to patients is becoming greater and greater, especially in places where life is critical. The patients are directly exposed to various electrodes and sensors during surgery or anesthesia. Inserted into the human body, even the slight leakage current may cause the patient to be electrocuted. In addition, some medical equipment is used to maintain the lives of critically ill patients. Once the equipment is powered off, it will also threaten the lives of patients. Therefore, for the electrical design of the special place of the hospital, the IT system should be used for power supply in strict accordance with national standards and regulations.This article introduces the application of Medical isolated power supply in Pitsanulok hospital project.

项目背景Background

配电系统引起的触电和系统故障大多是设备线路接地故障引起的。接地故障会直接带来供电中断的危害；接地故障漏电严重时，甚至会烧毁电气设备或线路，造成无法弥补的损失。

在医疗场所，特别是那些危及生命的二级医疗场所，处于手术或麻醉状态的患者，没有自我行为能力，小漏电流可导致患者触电死亡。因此，该特殊场所的电气设计应严格按照国家有关标准和规范进行。

Electric shock and system fault caused by power distribution system are mostly caused by the grounding fault of equipment line. Grounding fault will directly bring the harm of power supply interruption; when the earth fault leakage is serious, it will even burn electrical equipment or lines, causing irreparable loss.

In Medical places, especially those life-threatening class 2 medical places, patients in surgery or anesthesia state, without self-behavior ability, small leakage current can lead to electric shock death of patients. Therefore, the electrical design of this special place should be carried out strictly in accordance with the relevant national standards and specifications.

IT配电系统（又称隔离供电系统或不接地系统）由于其中性点不接地，对地漏电流非常小。发生第一次绝缘故障时，不会影响设备的供电。所以系统可以继续运行。安装在系统中的绝缘监测装置可以及时发现故障并发出相应的故障警告，提示相关人员在适当的时候排除故障。对于手术室、重症监护室等对供电连续性和安全性要求较高的医疗场所，本地IT系统供电可以保证重要负载供电的安全性和可靠性。

IT power distribution system (also known as isolated power supply system or ungrounded system) has very small leakage current to ground due to its neutral point ungrounded. When the first insulation fault occurs, the power supply of the equipment will not be affected. So the system can continue to operate. The insulation monitoring device installed in the system can detect the fault in time and send out the corresponding fault warning, prompting the relevant personnel to remove the fault at the appropriate time. For the operation room, intensive care unit and other medical places with high requirements for power supply continuity and safety, local IT system power supply can ensure the security and reliability of power supply for important loads.
