變電箱的工作原理是什么

變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)也(ye)被人(ren)們稱為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)，是(shi)一(yi)(yi)種能深入負荷(he)中心的(de)(de)設(she)(she)備，變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)實質上就(jiu)是(shi)把(ba)高壓(ya)(ya)(ya)開(kai)關的(de)(de)設(she)(she)備、低(di)壓(ya)(ya)(ya)配(pei)置(zhi)(zhi)的(de)(de)開(kai)關、變(bian)壓(ya)(ya)(ya)器降壓(ya)(ya)(ya)、高壓(ya)(ya)(ya)受壓(ya)(ya)(ya)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能計算器設(she)(she)備、無(wu)功補償的(de)(de)裝置(zhi)(zhi)（電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣二次設(she)(she)備）組合在一(yi)(yi)起的(de)(de)，使用于(yu)(yu)額定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)相互交換的(de)(de)系(xi)統電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)終端(duan)，它(ta)(ta)還(huan)可(ke)以(yi)用作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)和(he)分配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能等，是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)系(xi)統對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)改變(bian)和(he)分配(pei)的(de)(de)箱(xiang)子，安(an)裝在一(yi)(yi)個防(fang)潮、防(fang)火(huo)、防(fang)盜、防(fang)鼠、防(fang)銹、防(fang)塵(chen)、全(quan)部封閉(bi)到可(ke)以(yi)移動的(de)(de)箱(xiang)子體內。由(you)于(yu)(yu)它(ta)(ta)擁有占地面積(ji)較小等特點，故適合用在一(yi)(yi)些工(gong)礦企業、居民住宅小區(qu)等場所；由(you)于(yu)(yu)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)箱(xiang)擁有的(de)(de)這些獨特特點，故它(ta)(ta)還(huan)使用于(yu)(yu)風力(li)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站。因(yin)為(wei)它(ta)(ta)的(de)(de)出現代替了原來的(de)(de)土建電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)房。

雖然(ran)變(bian)電(dian)(dian)(dian)箱(xiang)給我(wo)們(men)的(de)(de)生活中(zhong)帶來方便，但是既(ji)然(ran)它(ta)有好的(de)(de)一(yi)面那就(jiu)必定有不足的(de)(de)一(yi)面，因為變(bian)電(dian)(dian)(dian)箱(xiang)是一(yi)種(zhong)高(gao)輻射(she)(she)的(de)(de)設(she)備，故我(wo)們(men)應該離(li)變(bian)電(dian)(dian)(dian)箱(xiang)遠一(yi)些，不要(yao)長(chang)(chang)期待在變(bian)電(dian)(dian)(dian)箱(xiang)旁(pang)，醫生表明：長(chang)(chang)期處(chu)(chu)于(yu)(yu)高(gao)輻射(she)(she)環(huan)境中(zhong)，會使我(wo)們(men)的(de)(de)血液、淋巴液、細胞原生質發生改變(bian)，還(huan)能誘(you)發癌細胞的(de)(de)增長(chang)(chang)等。故我(wo)們(men)不要(yao)長(chang)(chang)期處(chu)(chu)于(yu)(yu)高(gao)輻射(she)(she)環(huan)境中(zhong)。

變電箱安全距離是多少

國家規定變電箱(xiang)距(ju)(ju)離(li)住宅的安全距(ju)(ju)離(li)是：

1、1kV以下高壓(ya)線的安(an)全距(ju)離為4米。

2、1-10kV高壓線(xian)的(de)安全(quan)距離為(wei)6米。

3、35-110kV高壓線(xian)的安全(quan)距離為8米。

變電箱的特點

變電(dian)(dian)箱是電(dian)(dian)力系統(tong)對電(dian)(dian)壓和(he)(he)電(dian)(dian)流的(de)改(gai)變和(he)(he)分配的(de)箱子。它(ta)的(de)目的(de)就是為了(le)保(bao)(bao)證(zheng)電(dian)(dian)能(neng)的(de)質(zhi)量和(he)(he)設備的(de)安全(quan)，在這種前提條件下進(jin)行必要(yao)的(de)電(dian)(dian)壓調整，系統(tong)中各節點和(he)(he)其余支路(lu)的(de)電(dian)(dian)壓和(he)(he)保(bao)(bao)護(hu)輸配電(dian)(dian)路(lu)等功能(neng)。

變電(dian)箱是采用(yong)的(de)模塊化的(de)設計(ji)，它可(ke)(ke)以(yi)是由不同的(de)模塊組合實(shi)(shi)現的(de)各個主接線(xian)，同時(shi)還(huan)可(ke)(ke)以(yi)根據(ju)不同的(de)需要變換(huan)組合的(de)形式來(lai)形成回(hui)路開(kai)關系統(tong)。同時(shi)還(huan)能用(yong)不同的(de)界面絕緣結構，實(shi)(shi)現了高壓部(bu)件的(de)插接或(huo)是柜(ju)體的(de)一個擴展，用(yong)全屏(ping)蔽型(xing)的(de)電(dian)纜進出線(xian)來(lai)實(shi)(shi)現。

變電箱的危害

1、是造(zao)成兒童(tong)患(huan)白血(xue)病的(de)原(yuan)因(yin)之一(yi)。醫學研(yan)究證明(ming)，長期處于(yu)高電(dian)磁輻射(she)的(de)環境中(zhong)，會使血(xue)液(ye)(ye)、淋巴液(ye)(ye)和細胞原(yuan)生質發(fa)生改變。意大利專家研(yan)究后認為，該國每(mei)年有400多名兒童(tong)患(huan)白血(xue)病，其主要原(yuan)因(yin)是距離高壓電(dian)線太近，因(yin)而受到(dao)了嚴重的(de)電(dian)磁污染。

2、能夠誘發癌(ai)癥(zheng)并加(jia)(jia)速(su)人體的(de)癌(ai)細胞(bao)(bao)增殖(zhi)。電磁輻射污染(ran)會(hui)影響人體的(de)循(xun)環(huan)系統、免疫(yi)、代謝功能，嚴重(zhong)的(de)還(huan)會(hui)誘發癌(ai)癥(zheng)，并會(hui)加(jia)(jia)速(su)人體的(de)癌(ai)細胞(bao)(bao)增殖(zhi)。
