山西景泰(tai)電氣電器箱體(ti)和配(pei)電箱的大致作用是相互(hu)獨(du)立的，其基(ji)本區別應如下(xia)：

 1.從用(yong)(yong)途上講(jiang)，配電(dian)(dian)(dian)箱一般為(wei)家用(yong)(yong)，而(er)配電(dian)(dian)(dian)柜(ju)多用(yong)(yong)于集中供電(dian)(dian)(dian)，例(li)如(ru)，工業用(yong)(yong)電(dian)(dian)(dian)和建(jian)筑用(yong)(yong)電(dian)(dian)(dian)，配電(dian)(dian)(dian)箱和配電(dian)(dian)(dian)柜(ju)屬于家用(yong)(yong)設備，配電(dian)(dian)(dian)箱屬于低壓成套設備。

 2.從外觀上看，配(pei)(pei)電(dian)(dian)箱(xiang)是放在地上，其(qi)體(ti)積與電(dian)(dian)冰箱(xiang)相似(si)。配(pei)(pei)電(dian)(dian)箱(xiang)體(ti)積小，如一只箱(xiang)子(zi)被(bei)固(gu)定(ding)在墻(qiang)上。 配(pei)(pei)電(dian)(dian)室的電(dian)(dian)氣會合有(you)什么(me)問題(ti)？ 1.由(you)環境溫度造成的低(di)壓電(dian)(dian)器故障。 配(pei)(pei)電(dian)(dian)箱(xiang)中的低(di)壓電(dian)(dian)器，由(you)熔斷器(qi)(qi)(qi).交流(liu)接(jie)觸(chu)(chu)器(qi)(qi)(qi).剩余電(dian)流(liu)動作保護(hu)器(qi)(qi)(qi).電(dian)容和儀(yi)表(biao)等組成(cheng)。這類低壓(ya)電(dian)器(qi)(qi)(qi)都是按(an)照(zhao)基本標準設(she)計和制造(zao)的(de)(de)(de)，并相應地規定了環境(jing)空(kong)(kong)(kong)氣(qi)溫(wen)度(du)(du)的(de)(de)(de)Z高限(xian)值：環境(jing)空(kong)(kong)(kong)氣(qi)溫(wen)度(du)(du)的(de)(de)(de)Z高限(xian)值為(wei)40℃，平(ping)均24h為(wei)24℃；周圍空(kong)(kong)(kong)氣(qi)溫(wen)度(du)(du)的(de)(de)(de)下限(xian)為(wei)-5℃、-25℃。 農村電(dian)網(wang)(wang)改造(zao)后的(de)(de)(de)配電(dian)柜在戶外運(yun)(yun)行，它不(bu)(bu)僅受(shou)到(dao)太陽光的(de)(de)(de)直接(jie)照(zhao)射(she)而產(chan)生高溫(wen)，同時(shi)自(zi)身也會(hui)產(chan)生熱量，因此(ci)，當(dang)溫(wen)度(du)(du)大大超(chao)過這些電(dian)器(qi)(qi)(qi)所規定的(de)(de)(de)環境(jing)溫(wen)度(du)(du)時(shi)，箱內的(de)(de)(de)溫(wen)度(du)(du)將會(hui)達到(dao)60℃以上，此(ci)時(shi)，因此(ci)，配電(dian)箱中也會(hui)出現電(dian)器(qi)(qi)(qi)元件過熱而造(zao)成(cheng)的(de)(de)(de)故障(zhang)。 2.由產(chan)品(pin)質(zhi)量造(zao)成(cheng)的(de)(de)(de)故障(zhang)。 當(dang)時(shi)農網(wang)(wang)改造(zao)所需的(de)(de)(de)配電(dian)柜數量大、施(shi)工(gong)期(qi)短，需配電(dian)時(shi)間較(jiao)長，需配電(dian)時(shi)間較(jiao)長，因此(ci)對產(chan)品(pin)質(zhi)量要求(qiu)不(bu)(bu)高，導致(zhi)出現了對產(chan)品(pin)質(zhi)量要求(qiu)不(bu)(bu)高的(de)(de)(de)現象。如果一(yi)些型號(hao)的(de)(de)(de)交流(liu)接(jie)觸(chu)(chu)器(qi)(qi)(qi)在配電(dian)箱投運(yun)(yun)不(bu)(bu)久，由于(yu)接(jie)觸(chu)(chu)器(qi)(qi)(qi)合閘線圈燒壞，不(bu)(bu)能(neng)正常工(gong)作。

 3.配電(dian)箱中(zhong)(zhong)電(dian)器選擇(ze)不(bu)當(dang)造成的(de)故障。 對(dui)于交(jiao)流接觸(chu)器在(zai)生產過程中(zhong)(zhong)的(de)容(rong)量(liang)選擇(ze)不(bu)當(dang)，應在(zai)不(bu)同(tong)的(de)輸出回(hui)路安裝相(xiang)同(tong)容(rong)量(liang)的(de)交(jiao)流接觸(chu)器。而且沒有考慮到(dao)三相(xiang)負荷的(de)不(bu)平衡情況(kuang)，沒有把部分出線接觸(chu)器的(de)電(dian)流等級定為正常選型，對(dui)電(dian)流等級的(de)改進，從(cong)而造成夏季高溫(wen)季節運(yun)行時的(de)交(jiao)流接觸(chu)器燒(shao)壞。

山西(xi)景泰電(dian)氣(qi)低(di)壓配電(dian)箱(xiang)怎么接(jie)地？ 低(di)壓配電(dian)箱(xiang)作為(wei)調節電(dian)路(lu)系(xi)統的設備，更需要(yao)這一(yi)(yi)點，那么低(di)壓配電(dian)箱(xiang)應該如何接(jie)地呢(ni)？講解一(yi)(yi)下(xia)低(di)壓配電(dian)箱(xiang)的接(jie)地方(fang)法。 

低壓(ya)配電(dian)(dian)(dian)(dian)箱 TT接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)力系(xi)統(tong)第一(yi)個(ge)字(zi)(zi)母t表(biao)示(shi)電(dian)(dian)(dian)(dian)力系(xi)統(tong)中性點直(zhi)接(jie)(jie)(jie)接(jie)(jie)(jie)地(di)，第二(er)個(ge)字(zi)(zi)母t表(biao)示(shi)負(fu)荷設備(bei)裸露的(de)金屬導電(dian)(dian)(dian)(dian)部分(fen)不(bu)與(yu)帶電(dian)(dian)(dian)(dian)體連接(jie)(jie)(jie)而是直(zhi)接(jie)(jie)(jie)接(jie)(jie)(jie)地(di)，與(yu)系(xi)統(tong)的(de)接(jie)(jie)(jie)地(di)方(fang)式無關。TT系(xi)統(tong)中的(de)所有接(jie)(jie)(jie)地(di)負(fu)載稱為保(bao)(bao)護接(jie)(jie)(jie)地(di)。 TN-S是將工作(zuo)零線(xian)N與(yu)專(zhuan)用(yong)保(bao)(bao)護線(xian)pe嚴格(ge)分(fen)開的(de)供電(dian)(dian)(dian)(dian)系(xi)統(tong)。稱之(zhi)(zhi)為TN-S供電(dian)(dian)(dian)(dian)系(xi)統(tong)。TN-S供電(dian)(dian)(dian)(dian)系(xi)統(tong)正常運行(xing)時，專(zhuan)用(yong)保(bao)(bao)護線(xian)上無電(dian)(dian)(dian)(dian)流，PE線(xian)與(yu)地(di)之(zhi)(zhi)間無電(dian)(dian)(dian)(dian)壓(ya)。電(dian)(dian)(dian)(dian)氣(qi)設備(bei)金屬外殼(ke)的(de)零保(bao)(bao)護接(jie)(jie)(jie)PE專(zhuan)用(yong)保(bao)(bao)護線(xian)，安全(quan)可靠。

低(di)(di)壓配電(dian)(dian)箱廠家(jia)表(biao)示，這適用(yong)于(yu)工(gong)(gong)業、民(min)用(yong)建筑等(deng)低(di)(di)壓供電(dian)(dian)系(xi)統。 TN-C-S處于(yu)施(shi)工(gong)(gong)臨時供電(dian)(dian)狀態。如果前部采(cai)用(yong)tn-c方式(shi)供電(dian)(dian)，施(shi)工(gong)(gong)規范規定施(shi)工(gong)(gong)現場必須采(cai)用(yong)tn-s方式(shi)供電(dian)(dian)系(xi)統，則pe線(xian)可在虛線(xian)后段用(yong)低(di)(di)壓配電(dian)(dian)箱隔開施(shi)工，稱為tn-c-s供(gong)電(dian)(dian)系(xi)(xi)統。 Tn供(gong)電(dian)(dian)系(xi)(xi)統和tn-c供(gong)電(dian)(dian)系(xi)(xi)統是連接(jie)電(dian)(dian)氣設備金屬(shu)外殼與工作(zuo)零(ling)(ling)線(xian)的保護系(xi)(xi)統。低壓配電(dian)(dian)箱廠家表示(shi)，這叫接(jie)零(ling)(ling)保護系(xi)(xi)統，tn-c供(gong)電(dian)(dian)系(xi)(xi)統采用工作(zuo)零(ling)(ling)線(xian)作(zuo)為接(jie)零(ling)(ling)保護線(xian)，可稱為保護零(ling)(ling)線(xian)。
