醫(yi)(yi)用(yong)隔離電(dian)(dian)(dian)(dian)(dian)(dian)源系(xi)(xi)統(tong)(IT系(xi)(xi)統(tong))目的(de)(de)就是(shi)保(bao)(bao)證為該場所(suo)內(nei)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)器提(ti)供(gong)(gong)一個安(an)(an)全的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源，以確保(bao)(bao)的(de)(de)安(an)(an)全。當電(dian)(dian)(dian)(dian)(dian)(dian)網負(fu)載端出現個絕(jue)緣故障(zhang)(zhang)點時，不會引起電(dian)(dian)(dian)(dian)(dian)(dian)源空開動(dong)作（跳閘(zha)），保(bao)(bao)證了供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)連續(xu)性。通常醫(yi)(yi)院(yuan)內(nei)電(dian)(dian)(dian)(dian)(dian)(dian)力供(gong)(gong)應都由兩路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)源提(ti)供(gong)(gong)(一路(lu)為公(gong)共電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)源，另路(lu)為后(hou)備電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)源、發電(dian)(dian)(dian)(dian)(dian)(dian)機或電(dian)(dian)(dian)(dian)(dian)(dian)池)，醫(yi)(yi)用(yong)隔離電(dian)(dian)(dian)(dian)(dian)(dian)源系(xi)(xi)統(tong)生(sheng)產(chan)廠家，因為醫(yi)(yi)院(yuan)內(nei)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力供(gong)(gong)應正(zheng)常與(yu)否(fou)往往關系(xi)(xi)到(dao)患者的(de)(de)生(sheng)命安(an)(an)危。軟件可單獨調(diao)用(yong)某個IT供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)的(de)(de)監(jian)測(ce)畫面，并可通過手(shou)動(dong)選擇該系(xi)(xi)統(tong)隔離變(bian)壓器運行(xing)的(de)(de)詳細狀態，具有斷線故障(zhang)(zhang)檢測(ce)功能。

系(xi)統具有一(yi)次(ci)圖及(ji)現場分布(bu)圖顯示功(gong)能，便于及(ji)時(shi)、直(zhi)觀地(di)(di)發現IT供(gong)電(dian)系(xi)統的(de)(de)(de)報警(jing)(jing)地(di)(di)點(dian)或區域；醫(yi)用隔(ge)(ge)離(li)電(dian)源(yuan)集中(zhong)監控器(qi)的(de)(de)(de)顯示屏為觸摸(mo)顯示方(fang)式。通過(guo)系(xi)統，可根據要求遠(yuan)程調整(zheng)和設置(zhi)各醫(yi)用隔(ge)(ge)離(li)電(dian)源(yuan)系(xi)統中(zhong)絕緣(yuan)監測儀(yi)的(de)(de)(de)各類(lei)報警(jing)(jing)參數閾值，也可以任意查看這些(xie)報警(jing)(jing)參數值。如果在負(fu)載端(duan)出(chu)現相對絕緣(yuan)故(gu)障時(shi)，故(gu)障電(dian)流將經過(guo)電(dian)源(yuan)中(zhong)性(xing)點(dian)對地(di)(di)構(gou)成回路(lu)，從而形成一(yi)個較大的(de)(de)(de)故(gu)障電(dian)流，使上一(yi)級空開或熔斷器(qi)動(dong)作，終導致供(gong)電(dian)中(zhong)斷。

一旦隔離電(dian)(dian)(dian)源上(shang)所(suo)接(jie)的(de)(de)(de)負載（如(ru)各種醫用電(dian)(dian)(dian)氣設備）出現(xian)對(dui)(dui)地(di)故(gu)(gu)障，因(yin)對(dui)(dui)地(di)不能構成(cheng)回(hui)路，只能產(chan)生(sheng)一個很小的(de)(de)(de)容性漏(lou)(lou)電(dian)(dian)(dian)流(liu)，極大地(di)保(bao)護了(le)患者(zhe)免遭(zao)漏(lou)(lou)電(dian)(dian)(dian)流(liu)的(de)(de)(de)傷害。如(ru)果在負載端出現(xian)相對(dui)(dui)絕(jue)緣故(gu)(gu)障時，故(gu)(gu)障電(dian)(dian)(dian)流(liu)將經過電(dian)(dian)(dian)源中(zhong)性點對(dui)(dui)地(di)構成(cheng)回(hui)路，從而形(xing)成(cheng)一個較大的(de)(de)(de)故(gu)(gu)障電(dian)(dian)(dian)流(liu)，使上(shang)一級空開(kai)或熔斷(duan)器動作，終導致供(gong)電(dian)(dian)(dian)中(zhong)斷(duan)。在醫院的(de)(de)(de)特殊環境里(li)，漏(lou)(lou)電(dian)(dian)(dian)流(liu)對(dui)(dui)患者(zhe)構成(cheng)了(le)潛在的(de)(de)(de)危險，因(yin)此對(dui)(dui)電(dian)(dian)(dian)氣安全設計也提(ti)出了(le)特殊的(de)(de)(de)要求。為了(le)有效防止微(wei)電(dian)(dian)(dian)流(liu)的(de)(de)(de)發生(sheng)，國(guo)際(ji)上(shang)現(xian)普遍采(cai)用帶絕(jue)緣監(jian)視的(de)(de)(de)不接(jie)地(di)電(dian)(dian)(dian)源(IT系統)給手術室等(deng)場所(suo)供(gong)電(dian)(dian)(dian)。
