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

摘要: 現(xiàn)代醫院的(dí)診(zhěn)斷(duàn)和治療，離不開各(gè)種的醫療設備，而(ér)各種設備(bèi)都離不開安(ān)全可靠(kào)的供(gōng)電
。很多手術往往(wǎng)長(cháng)達(dá)數小(xiǎo)時，手術過程中(zhōng)突(tū)然斷電的話後(hòu)果不可(kě)想象；同(tóng)時很(hěn)多醫療器械都直(zhí)接接(jiē)觸或(huò)深入人體(tǐ)髒器(qì)，此(cǐ)時(shí)較小的漏電流(liú)都會(huì)威脅(xié)病人的生命安(ān)全
。因(yīn)此(cǐ)，針對(duì)醫院(yuàn)配(pèi)電係統(tǒng)供(gōng)電(diàn)的連續(xù)性和安(ān)全(quán)性，國家相關標(biāo)準作(zuò)了(liǎo)明(míng)確(què)要(yào)求，醫療2類(lèi)場(cháng)所重要設備須用(yòng)IT係統供電，同(tóng)時IT係統需要配(pèi)置絕緣(yuán)監測(cè)裝(zhuāng)置(zhì)

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項目(mù)概(gài)述(shù)

安哥拉(lā)羅(luó)安(ān)達(dá)總醫院(yuàn)是由中鐵(tiě)四局(jú)承擔的中國援(yuán)安(ān)哥(gē)拉(lā)羅安(ān)達總(zǒng)醫(yī)院改擴(kuò)建(jiàn)項目(mù)，該(gāi)項(xiàng)目使用了8套安科瑞(ruì)醫療IT係(xì)統產品
。主(zhǔ)要(yào)包括：AITR係列隔離(lí)變(biàn)壓(yā)器(qì)，AIM-M係列(liè)絕緣監測(cè)儀(yí)，AID係列(liè)報(bào)警顯(xiǎn)示儀和AKH-0.66P26電流互(hù)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(yī)療IT係統(tǒng)介(jiè)紹(shào)

醫用(yòng)隔(gé)離(lí)電源係統就(jiù)是通(tōng)過醫用隔離(lí)變(biàn)壓器將接(jiē)地係統(tǒng)（TN-S係(xì)統(tǒng)）轉接成不接(jiē)地係(xì)統(tǒng)（IT係統(tǒng)）來(lái)為重要(yào)的醫療(liáo)設備供電
。IT係統通過絕緣(yuán)監測(cè)儀(yí)實現絕(jué)緣監(jiān)測(cè)，通過絕緣(yuán)故(gù)障產品(pǐn)進(jìn)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(liáo)IT解(jiě)決方(fāng)案(àn)

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(shù)室配電解決(jué)方案

方案一(yī) 不(bù)帶絕緣故障(zhàng)定位功能

Option I  without insulation fault location function

方案(àn)二(èr) 帶(dài)絕緣(yuán)故障(zhàng)定(dìng)位功能

Option II  with insulation fault location function

注(zhù)：1.在(zài)手(shǒu)術室(shì)的配電解決(jué)方(fāng)案中，AID係列外接報警與(yǔ)顯示儀應(yīng)安裝(zhuāng)於(yú)手(shǒu)術(shù)室內部情(qíng)報(bào)麵板上，或(huò)情(qíng)報麵板(bǎn)的(dí)旁(páng)邊（嵌(qiàn)牆安(ān)裝）
。在手術(shù)過(guò)程中，由醫(yī)務人員(yuán)來(lái)監(jiān)視隔離電源係統的運行狀況(kuàng)
。

    2.帶絕(jué)緣(yuán)故(gù)障定(dìng)位(wèi)功(gōng)能(néng)的(dí)方(fāng)案中，如(rú)果需(xū)定(dìng)位回路超過(guò)8路，可采(cǎi)用兩套(tào)AIL150定位(wèi)儀來(lái)實現，其組(zǔ)合(hé)可以是AIL150-8型(xíng)+AIL150-4型(xíng)(可多定(dìng)位12路(lù))，或AIL150-8型(xíng)+AIL150-8型（可多定位(wèi)16路(lù)）
。

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).
