摘要: 現代醫院的診斷和治療，離不開各種先進的醫療設備，而各種設備都離不開安全可靠的供電。很多手術往往長達數小時，手術過程中突然斷電的話后果不可想象；同時很多醫療器械都直接接觸或深入人體臟器，此時較小的漏電流都會威脅病人的生命安全。因此，針對醫院配電系統供電的連續性和安全性，國家相關標準作了明確要求，醫療2類場所重要設備須用IT系統供電，同時IT系統需要配置絕緣監測裝置。本文介紹了安科瑞醫療IT系統在安哥拉羅安達總醫院的應用。

Abstract: Diagnosis and treatment in modern hospitals are inseparable from advanced medical equipment, which are inseparable from safe and reliable power supply. Many operations often last for several hours, and the consequences of a sudden power failure during the operation are unimaginable. At the same time, many medical devices directly touch or penetrate into the human organs. At this time, the very small leakage current will threaten the life of the patient. Therefore, the national standards have made clear requirements, medical group 2 locations must be powered by IT system. This article introduces the application of Acrel Medical IT System in Luanda General Hospital, Angola.

關鍵詞: 醫療IT，絕緣監測裝置，報警顯示儀。

1.Project Overview項目概述

安哥拉羅安達總醫院是由中鐵四局承擔的中國援安哥拉羅安達總醫院改擴建項目，該項目使用了8套安科瑞醫療IT系統產品。主要包括：AITR系列隔離變壓器，AIM-M系列絕緣監測儀，AID系列報警顯示儀和AKH-0.66P26電流互感器。

Luanda General Hospital in Angola is a China-aided reconstruction and expansion project of Luanda General Hospital in Angola undertaken by China Railway Fourth Bureau. The project uses 8 sets of Acrel medical IT system products. They are AITR series isolation transformer, AKH-0.66P26 current transformer, AIM-M series insulation monitoring device, AID series remote alarm indicator and DC power supply unit.

2.Introduction of Medical Isolated Power Supply System 醫療IT系統介紹

醫用隔離電源系統就是通過醫用隔離變壓器將接地系統（TN-S系統）轉接成不接地系統（IT系統）來為重要的醫療設備供電。IT系統通過絕緣監測儀實現絕緣監測，通過絕緣故障產品進行絕緣故障定位。

The medical isolated power supply system is to switch the grounding system (TN-S system) into ungrounded system (IT system) through a medical isolation transformer to supply power for important medical equipment. The insulation monitoring device has the function of insulation monitoring and fault locator has the function of fault circuit locating.

3.Acrel Medical Isolated Power Supply System Solutions 安科瑞醫療IT解決方案

Acrel medical isolated power supply system is suitable for operating room, ICU, CCU and other medical group 2 locations providing safe and uninterruptible power supply. It mainly includes AITR series isolation transformer, AKH-0.66P26 current transformer, AIM-M series insulation monitoring device, AID series remote alarm indicator, DC power supply, ASG series test signal generator and AIL series insulation fault locator.

3.1 Acrel Medical Isolated Power Supply System for Operating Room 手術室配電解決方案

方案一 不帶絕緣故障定位功能

Option I without insulation fault location function

方案二 帶絕緣故障定位功能

Option II with insulation fault location function

注：1.在手術室的配電解決方案中，AID系列外接報警與顯示儀應安裝于手術室內部情報面板上，或情報面板的旁邊（嵌墻安裝）。在手術過程中，由醫務人員來監視隔離電源系統的運行狀況。

2.帶絕緣故障定位功能的方案中，如果需定位回路超過8路，可采用兩套AIL150定位儀來實現，其組合可以是AIL150-8型+AIL150-4型(可多定位12路)，或AIL150-8型+AIL150-8型（可多定位16路）。

Note: 1. For operating room, AID series alarm indicator should be installed on the intelligence panel inside the operating room, or next to the intelligence panel (wall mounted installation) so that medical personnel can immediately receive a notification when there is power supply failure.

2.In Option II，if the number of located channels is more than eight，two sets of AIL150 can be used. The combination can be AIL150-8 and AIL150-4 (up to 12 channels), or AIL150 -8 and AIL150-8 (up to 16 channels).

3.2 Acrel Medical Isolated Power Supply System for ICU and CCU ICU,CCU配電解決方案

方案一 不帶絕緣故障定位功能

Option I without insulation fault location function

方案二 帶絕緣故障定位功能

Option II with insulation fault location function

注：在重癥監護室的配電解決方案中，AID系列集中報警與顯示儀應該安裝在護士站內，由護士站的醫務人員來監視各隔離電源系統的運行狀況。

Note: For intensive care unit , AID series alarm indicator should be installed in the nurses 'station so that medical personnel can monitor the operating status of isolated power supply system.
