環(huan)網柜檢(jian)漏(lou)原理主(zhu)要基于SF6氣體絕緣的特性。當泄(xie)漏(lou)達到一定程度(du)時，壓力降(jiang)低(di)到報警值以下(xia)，控制器(qi)自(zi)動(dong)啟動(dong)閥進行并發出信號至微機主(zhu)機或繼電器(qi)；若繼續(xu)下(xia)降(jiang)低(di)于閉鎖值為(wei)80%，則關閉主(zhu)回路電源（即跳閘）。

斷路(lu)(lu)器檢漏作(zuo)用(yong)是(shi)指在(zai)電(dian)(dian)路(lu)(lu)中存在(zai)漏電(dian)(dian)流(liu)(liu)時(shi)，斷路(lu)(lu)器會自動檢測(ce)到(dao)這種漏電(dian)(dian)流(liu)(liu)，并將電(dian)(dian)路(lu)(lu)斷開，以防止漏電(dian)(dian)流(liu)(liu)造成的(de)危害。斷路(lu)(lu)器通常使用(yong)在(zai)低壓配電(dian)(dian)系統(tong)中，其(qi)作(zuo)用(yong)是(shi)保護電(dian)(dian)路(lu)(lu)免受(shou)過電(dian)(dian)流(liu)(liu)和短路(lu)(lu)的(de)損害。檢漏作(zuo)用(yong)是(shi)斷路(lu)(lu)器重要的(de)功能之一，因此在(zai)選擇(ze)和安裝(zhuang)斷路(lu)(lu)器時(shi)，應該考慮其(qi)檢漏性能。

環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)是(shi)(shi)一種(zhong)電(dian)(dian)氣設(she)(she)備，電(dian)(dian)力行(xing)(xing)業(ye)檢(jian)(jian)(jian)(jian)漏廠，用(yong)于連接(jie)電(dian)(dian)源和負載。檢(jian)(jian)(jian)(jian)漏操(cao)(cao)作是(shi)(shi)確保(bao)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部絕(jue)緣性(xing)能的(de)(de)重(zhong)要步驟(zou)。以(yi)下(xia)是(shi)(shi)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)檢(jian)(jian)(jian)(jian)漏操(cao)(cao)作的(de)(de)原理：1.使用(yong)低(di)壓電(dian)(dian)源進(jin)行(xing)(xing)操(cao)(cao)作：檢(jian)(jian)(jian)(jian)漏操(cao)(cao)作通(tong)(tong)常使用(yong)低(di)壓電(dian)(dian)源，因為低(di)壓電(dian)(dian)源的(de)(de)電(dian)(dian)壓較低(di)，不會(hui)對(dui)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部的(de)(de)電(dian)(dian)氣設(she)(she)備造成損害(hai)。2.使用(yong)真空(kong)(kong)設(she)(she)備進(jin)行(xing)(xing)檢(jian)(jian)(jian)(jian)漏：真空(kong)(kong)設(she)(she)備可(ke)(ke)(ke)(ke)以(yi)將(jiang)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部的(de)(de)空(kong)(kong)氣抽(chou)出，形成真空(kong)(kong)環(huan)(huan)(huan)境(jing)。在(zai)(zai)真空(kong)(kong)環(huan)(huan)(huan)境(jing)下(xia)，可(ke)(ke)(ke)(ke)以(yi)檢(jian)(jian)(jian)(jian)測(ce)(ce)到環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部的(de)(de)漏電(dian)(dian)情況(kuang)。3.使用(yong)超聲(sheng)波(bo)檢(jian)(jian)(jian)(jian)測(ce)(ce)儀(yi)進(jin)行(xing)(xing)檢(jian)(jian)(jian)(jian)漏：超聲(sheng)波(bo)檢(jian)(jian)(jian)(jian)測(ce)(ce)儀(yi)可(ke)(ke)(ke)(ke)以(yi)發射(she)超聲(sheng)波(bo)，通(tong)(tong)過檢(jian)(jian)(jian)(jian)測(ce)(ce)超聲(sheng)波(bo)在(zai)(zai)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部的(de)(de)反射(she)情況(kuang)來判斷(duan)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部是(shi)(shi)否(fou)(fou)存在(zai)(zai)漏電(dian)(dian)。4.使用(yong)紅(hong)外熱像儀(yi)進(jin)行(xing)(xing)檢(jian)(jian)(jian)(jian)漏：紅(hong)外熱像儀(yi)可(ke)(ke)(ke)(ke)以(yi)檢(jian)(jian)(jian)(jian)測(ce)(ce)到環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部的(de)(de)溫度變化，從(cong)而判斷(duan)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)是(shi)(shi)否(fou)(fou)存在(zai)(zai)漏電(dian)(dian)情況(kuang)。總之，環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)檢(jian)(jian)(jian)(jian)漏操(cao)(cao)作是(shi)(shi)通(tong)(tong)過使用(yong)不同的(de)(de)檢(jian)(jian)(jian)(jian)測(ce)(ce)設(she)(she)備來檢(jian)(jian)(jian)(jian)測(ce)(ce)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)內(nei)(nei)部是(shi)(shi)否(fou)(fou)存在(zai)(zai)漏電(dian)(dian)情況(kuang)，以(yi)確保(bao)環(huan)(huan)(huan)網(wang)(wang)(wang)柜(ju)(ju)(ju)的(de)(de)絕(jue)緣性(xing)能。
