實現箱式變電站剩余電流的分級保護是一件非常細致的工作，該操作可以保護操作者的生命安全，因此不容忽視，由于每戶家的用電不同，也要做好詳細的記錄。①優質箱式變電站定期開展對剩余電流分級保護箱式變電站的巡視檢查和測試工作，監測負荷電流和剩余電流值，及時調整負荷或及時發現大的剩余電流線路和用電戶。②檢查剩余電流分級保護配電箱內上下引線，要壓接好，每運行一段時間后，要重新緊固，檢查箱門是否正常，有無漏雨現象。③箱式變電站哪里好加強箱(xiang)式變電(dian)站剩余電(dian)流動作(zuo)(zuo)(zuo)保(bao)護(hu)(hu)(hu)裝(zhuang)置(zhi)(zhi)的維護(hu)(hu)(hu)和(he)試跳工(gong)作(zuo)(zuo)(zuo)，分(fen)級保(bao)護(hu)(hu)(hu)箱(xiang)式變電(dian)站內(nei)的剩余電(dian)流動作(zuo)(zuo)(zuo)保(bao)護(hu)(hu)(hu)裝(zhuang)置(zhi)(zhi)，每季(ji)度至(zhi)少檢查試跳一次，并(bing)作(zuo)(zuo)(zuo)好記錄。④建(jian)立并(bing)完善(shan)剩余電(dian)流動作(zuo)(zuo)(zuo)保(bao)護(hu)(hu)(hu)裝(zhuang)置(zhi)(zhi)的運行(xing)、檢查、試驗的管理辦法，建(jian)立剩余電(dian)流動作(zuo)(zuo)(zuo)保(bao)護(hu)(hu)(hu)裝(zhuang)置(zhi)(zhi)運行(xing)臺賬(zhang)，設立運行(xing)專責人，加強運行(xing)維護(hu)(hu)(hu)工(gong)作(zuo)(zuo)(zuo)。

箱式變電站目前在電力行業應用廣泛，它可以降低高次諧波對電網中長運行的干擾。為了方便我們更好地使用更該產品，就需要對其安裝、使用與常識有一定的了解。一、海南箱式變電站在混凝土墻或磚墻上固定箱式變電站時，采用暗配管及暗分線盒和明配管兩種方式。如有分線盒，先將盒內雜物清理干凈，然后將導線理順，分清支路和相序，按支路綁扎成束。待箱式變電站找準位置后，將導線端頭引至箱內或盤上，優質箱式變電站逐(zhu)個剝削導(dao)線端頭(tou)，再逐(zhu)個壓(ya)接在器(qi)具上，同(tong)時將(jiang)PE保護地(di)線壓(ya)在明顯的(de)地(di)方，并將(jiang)箱(xiang)（盤）調整平直后進行固定。在電具、儀表較(jiao)多的(de)盤面板安(an)裝完畢后，應先(xian)用儀表校對有無(wu)差錯，調整無(wu)誤(wu)后試送電，將(jiang)將(jiang)卡片框內的(de)卡片填寫(xie)好部(bu)位(wei)、編上號。

箱式變電站作為一種目前使用廣泛的變電站為我國電力行業提供了不少的收益，其獨特的結構設計使其具有普通變電站所不具有的一切技術特點，那么我們為了能更好的使用好變電站我們就一定要能熟悉好其相關技術參數。1、優質箱式變電站額定容量：指額定工作條件下箱式變電站的額定輸出能力。2、額定電壓：空載、額定分接下，端電壓的值（即一次、二次側電壓值）。3、空載損耗：空載條件下，箱式變電站的損耗（也叫鐵耗）。4、箱式變電站哪里好空(kong)(kong)載(zai)電(dian)(dian)(dian)流：空(kong)(kong)載(zai)條(tiao)件下，一(yi)(yi)次(ci)側(ce)線圈(quan)流過的(de)(de)(de)(de)(de)電(dian)(dian)(dian)流值。5、短路(lu)損耗：一(yi)(yi)次(ci)側(ce)通額定電(dian)(dian)(dian)流，二次(ci)短路(lu)時所產生(sheng)的(de)(de)(de)(de)(de)損耗（主要是線圈(quan)電(dian)(dian)(dian)阻產生(sheng)的(de)(de)(de)(de)(de)）。6、分接（抽頭(tou)(tou)）的(de)(de)(de)(de)(de)概念：為適合電(dian)(dian)(dian)網運行需(xu)要，一(yi)(yi)般的(de)(de)(de)(de)(de)箱式變電(dian)(dian)(dian)站高壓側(ce)都(dou)(dou)有抽頭(tou)(tou)，這些抽頭(tou)(tou)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)壓值都(dou)(dou)是用額定電(dian)(dian)(dian)壓的(de)(de)(de)(de)(de)百分比(bi)表(biao)示的(de)(de)(de)(de)(de)，即所謂的(de)(de)(de)(de)(de)分接電(dian)(dian)(dian)壓。

箱式變電站作為目前廣泛使用的變電站，其經過長時間的工作需要消耗大量的電能導致效率降低，現在開發出來的無功補償技術可以省去無用功率，從而降低能耗提高效率。電網輸出的功率包括兩部分：優質箱式變電站一是有功功率；二是無功功率。直接消耗電能，把箱式變電站中的電能轉變為機械能、熱能、化學能或聲能，利用這些能作功，這部分功率稱為有功功率；不消耗電能，只是把電能轉換為另一種形式的能，這種能作為箱式變電站能夠作功的條件，并且這種能是在電網中與電能進行周期性轉換，這部分功率稱為無功功率。箱式變電站哪里好如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁元(yuan)件(jian)建立磁場占用的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器建立電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場所占的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)感元(yuan)件(jian)中作功(gong)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)滯(zhi)后于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)90°。而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容元(yuan)件(jian)中作功(gong)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)超前(qian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)90°。在(zai)同一電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)感電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方向相反(fan)，互差180°。如(ru)果在(zai)箱式變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁元(yuan)件(jian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中有(you)比例地安裝電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容元(yuan)件(jian)，使兩(liang)者的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)相互抵消，使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)矢量與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)矢量之間的(de)(de)夾角縮小。

箱式變電站在長時間的使用過程中難免會發生故障，有故障時，要進行維修，不過不應急于動手，應先詢問弄清楚故障的前后經過及故障現象，做好檢查工作。1、調查情況：優質箱式變電站向操作者和故障在場人員詢問情況，包括故障外部表現、大致部位、發生故障時環境情況。如有無異常氣體、明火、熱源是否靠近箱式變電站、有無腐蝕性氣體侵入、有無漏水，是否有人修理過，修理的內容等等。2、初步檢查：根據調查的情況，看箱式變電站外部有無損壞、連線有無斷路、松動，絕緣有無燒焦，螺旋熔斷器的熔斷指示器是否跳出，箱式變電站哪里好電器有(you)無進(jin)水、油垢，開(kai)關位置是否正確等(deng)。3、試(shi)(shi)車：通過(guo)初步(bu)檢查(cha)，確認有(you)會使故障進(jin)一步(bu)擴大和造(zao)成(cheng)人(ren)身(shen)、設備(bei)事故后，可進(jin)一步(bu)試(shi)(shi)車檢查(cha)，試(shi)(shi)車中要注意有(you)無嚴重跳(tiao)火、異常(chang)氣味、異常(chang)聲音等(deng)現(xian)象，一經發(fa)現(xian)應立即停(ting)車，切斷電源(yuan)。注意檢查(cha)箱式變電站的(de)溫(wen)升及電器的(de)動作程序是否符合設備(bei)原理圖的(de)要求，從而(er)發(fa)現(xian)故障部位。

箱式變電站在使用過程中，設備本身就會散發出較多熱量，影響工作效率。尤其是在夏季高溫環境會產生更過熱耦合力，對設備的使用產生較大影響，嚴重時還可能引起短路，引發火災。①保證通風；②海南箱式變電站箱體盡量采用不銹鋼材質，不易生銹，并有熱反射效果，如定期噴涂具有保溫性能的涂層，以減少熱輻射，效果更理想；③高溫季節避免設備過載運行，并盡可能減少熱內箱內設備的釋放。為此在夏季應始終注意箱式變電站的溫度，箱式變電站哪里好一旦發現過熱應(ying)(ying)及時采(cai)取(qu)適當的(de)(de)措(cuo)施；④應(ying)(ying)盡量使用(yong)(yong)箱式變(bian)電(dian)站(zhan)兩側的(de)(de)百葉(xie)窗，中間的(de)(de)盒子不完全(quan)隔開，使空(kong)氣對(dui)流熱形(xing)成。在春季(ji)、夏(xia)季(ji)是(shi)用(yong)(yong)電(dian)的(de)(de)高(gao)(gao)峰(feng)期，箱式變(bian)電(dian)站(zhan)相應(ying)(ying)的(de)(de)溫(wen)度也會升高(gao)(gao)，為了避免危險(xian)的(de)(de)產(chan)生(sheng)，我們應(ying)(ying)采(cai)取(qu)通風散熱等方法來降低(di)溫(wen)度，并且多加檢(jian)查，避免發生(sheng)問題(ti)。
