【節(jié)能學院】安科瑞醫(yī)療IT產(chǎn)品在彭世洛醫(yī)院項目的設(shè)計與應用

摘要：隨著電子醫(yī)療設(shè)備在醫(yī)院領(lǐng)域的廣泛應用，漏電流對病人構(gòu)成的威脅也越來越大，尤其是那些生命攸關(guān)的場所，病人在手術(shù)中或麻醉狀態(tài)下，各種電極、傳感器直接插入人體內(nèi)，微小的漏電流都有可能導致病人觸電身亡。另外有些醫(yī)療設(shè)備用于維持重癥病人的生命，一旦設(shè)備停電，也會對病人的生命構(gòu)成威脅。因此，對于醫(yī)院這一特殊場所的電氣設(shè)計，應嚴格按照國家標準和規(guī)范要求，采用IT系統(tǒng)供電。本文介紹了醫(yī)療IT在彭世洛醫(yī)院的應用。

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.

項目背景Background

配電系統(tǒng)引起的觸電和系統(tǒng)故障大多是設(shè)備線路接地故障引起的。接地故障會直接帶來供電中斷的危害；接地故障漏電嚴重時，甚至會燒毀電氣設(shè)備或線路，造成無法彌補的損失。

在醫(yī)療場所，特別是那些危及生命的二級醫(yī)療場所，處于手術(shù)或麻醉狀態(tài)的患者，沒有自我行為能力，小漏電流可導致患者觸電死亡。因此，該特殊場所的電氣設(shè)計應嚴格按照國家有關(guān)標準和規(guī)范進行。

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配電系統(tǒng)（又稱隔離供電系統(tǒng)或不接地系統(tǒng)）由于其中性點不接地，對地漏電流非常小。發(fā)生第一次絕緣故障時，不會影響設(shè)備的供電。所以系統(tǒng)可以繼續(xù)運行。安裝在系統(tǒng)中的絕緣監(jiān)測裝置可以及時發(fā)現(xiàn)故障并發(fā)出相應的故障警告，提示相關(guān)人員在適當?shù)臅r候排除故障。對于手術(shù)室、重癥監(jiān)護室等對供電連續(xù)性和安全性要求較高的醫(yī)療場所，本地IT系統(tǒng)供電可以保證重要負載供電的安全性和可靠性。

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.
