Application of Acrel Medical Isolated Power Supply System in Luanda General Hospital, Angola


摘要: 现代医院的诊断和治疗,离不开各种的医疗设备,而各种设备都离不开安全可靠的供电。很多手术往往长达数小时,手术过程中突然断电的话后果不可想象;同时很多医疗器械都直接接触或深入人体脏器,此时较小的漏电流都会威胁病人的生命安全。因此,针对医院配电系统供电的连续性和安全性,国家相关标准作了明确要求,医疗2类场所重要设备须用IT系统供电,同时IT系统需要配置绝缘监测装置。本文介绍了安科瑞医疗IT系统在安哥拉罗安达总医院的应用。

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.

1.Project Overview项目概述

安哥拉罗安达总医院是由中铁四局承担的中国援安哥拉罗安达总医院改扩建项目,该项目使用了8套安科瑞医疗IT系统产品。主要包括:AITR系列隔离变压器,AIM-M系列绝缘监测仪,AID系列报警显示仪和AKH-0.66P26电流互感器。

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 医疗IT系统介绍

医用隔离电源系统就是通过医用隔离变压器将接地系统(TN-S系统)转接成不接地系统(IT系统)来为重要的医疗设备供电。IT系统通过绝缘监测仪实现绝缘监测,通过绝缘故障产品进行绝缘故障定位。

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 安科瑞医疗IT解决方案

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 手术室配电解决方案

方案一 不带绝缘故障定位功能

Option I  without insulation fault location function

方案二 带绝缘故障定位功能

Option II  with insulation fault location function

注:1.在手术室的配电解决方案中,AID系列外接报警与显示仪应安装于手术室内部情报面板上,或情报面板的旁边(嵌墙安装)。在手术过程中,由医务人员来监视隔离电源系统的运行状况。

    2.带绝缘故障定位功能的方案中,如果需定位回路超过8路,可采用两套AIL150定位仪来实现,其组合可以是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配电解决方案

方案一 不带绝缘故障定位功能

Option I  without insulation fault location function

方案二 带绝缘故障定位功能

Option II  with insulation fault location function

注:在重症监护室的配电解决方案中,AID系列集中报警与显示仪应该安装在护士站内,由护士站的医务人员来监视各隔离电源系统的运行状况。

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.
