　　在一(yi)般的(de)(de)(de)(de)(de)情況下特別是(shi)陰雨天氣的(de)(de)(de)(de)(de)時(shi)候，電(dian)(dian)力變壓器(qi)都是(shi)不停地進(jin)行(xing)(xing)使用的(de)(de)(de)(de)(de)，因(yin)(yin)為電(dian)(dian)力變壓器(qi)就(jiu)是(shi)用電(dian)(dian)磁感(gan)(gan)應的(de)(de)(de)(de)(de)原理(li)進(jin)行(xing)(xing)設計的(de)(de)(de)(de)(de)，因(yin)(yin)此的(de)(de)(de)(de)(de)話是(shi)不斷地進(jin)行(xing)(xing)向外(wai)發射電(dian)(dian)磁波(bo)和感(gan)(gan)應電(dian)(dian)流(liu)，形成(cheng)一(yi)種電(dian)(dian)磁感(gan)(gan)應現(xian)象(xiang)，與(yu)空中的(de)(de)(de)(de)(de)雷聲和閃(shan)電(dian)(dian)形成(cheng)的(de)(de)(de)(de)(de)電(dian)(dian)流(liu)兩(liang)者(zhe)之間(jian)進(jin)行(xing)(xing)進(jin)行(xing)(xing)結合的(de)(de)(de)(de)(de)話是(shi)產生一(yi)種閉合的(de)(de)(de)(de)(de)回路的(de)(de)(de)(de)(de)，一(yi)旦閉合回路形成(cheng)的(de)(de)(de)(de)(de)話就(jiu)會出現(xian)雷擊壞電(dian)(dian)力變壓器(qi)的(de)(de)(de)(de)(de)現(xian)象(xiang)，這時(shi)候就(jiu)要進(jin)行(xing)(xing)做消(xiao)磁處(chu)理(li)了。常見的(de)(de)(de)(de)(de)磁性是(shi)怎么進(jin)行(xing)(xing)消(xiao)除的(de)(de)(de)(de)(de)呢?

　　在(zai)(zai)實(shi)際工(gong)作中，開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)次級(ji)線(xian)圈會(hui)產(chan)生(sheng)(sheng)感應電(dian)(dian)(dian)(dian)(dian)動(dong)勢，并在(zai)(zai)次級(ji)線(xian)圈中產(chan)生(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)流(liu)，這個電(dian)(dian)(dian)(dian)(dian)流(liu)會(hui)對電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)鐵芯(xin)(xin)(xin)起到退磁(ci)(ci)的(de)(de)作用;而在(zai)(zai)用圖2-54、2-57、2-58的(de)(de)方(fang)法對開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)進行測試(shi)的(de)(de)過程(cheng)中，開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)次級(ji)線(xian)圈一般都開路，所以在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)次級(ji)線(xian)圈中不會(hui)產(chan)生(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)流(liu)，因此(ci)，在(zai)(zai)測試(shi)過程(cheng)中，迭(die)加電(dian)(dian)(dian)(dian)(dian)流(liu)一定會(hui)使開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)的(de)(de)鐵芯(xin)(xin)(xin)磁(ci)(ci)化帶磁(ci)(ci)，并且，當迭(die)加電(dian)(dian)(dian)(dian)(dian)流(liu)消失之后，開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)鐵芯(xin)(xin)(xin)帶磁(ci)(ci)的(de)(de)現象也(ye)不會(hui)消失。因此(ci)，在(zai)(zai)對開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)進行反復測試(shi)的(de)(de)過程(cheng)中，給開關(guan)電(dian)(dian)(dian)(dian)(dian)力(li)(li)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)鐵芯(xin)(xin)(xin)消磁(ci)(ci)是必(bi)要的(de)(de)。

　　開關(guan)電(dian)(dian)力變(bian)壓(ya)(ya)器鐵芯退磁(ci)的(de) 好方法是讓開關(guan)電(dian)(dian)力變(bian)壓(ya)(ya)器初(chu)級(ji)(ji)線圈在非常短的(de)時間(jian)內通過一(yi)個幅度為(wei)3～5倍(bei)Imax(極限電(dian)(dian)流(liu)(liu))的(de)阻(zu)(zu)尼振蕩電(dian)(dian)流(liu)(liu)，即讓流(liu)(liu)開關(guan)電(dian)(dian)力變(bian)壓(ya)(ya)器初(chu)級(ji)(ji)線圈的(de)電(dian)(dian)流(liu)(liu)由 大值逐漸減(jian)小到0。為(wei)此(ci)，可(ke)用一(yi)個20～40歐(ou)姆的(de)消(xiao)磁(ci)熱敏電(dian)(dian)阻(zu)(zu)與開關(guan)電(dian)(dian)力變(bian)壓(ya)(ya)器初(chu)級(ji)(ji)線圈串聯，然(ran)后接到110～220V/50Hz交流(liu)(liu)電(dian)(dian)源上，大約(yue)需要20多秒鐘，待消(xiao)磁(ci)熱敏電(dian)(dian)阻(zu)(zu)完(wan)全加熱后，即可(ke)達到退磁(ci)的(de)目的(de)。

　　電力(li)變壓器的(de)磁性是一個(ge)不斷地(di)進(jin)行過程(cheng)，大家要學會減小和(he)消除磁性的(de)常見的(de)方法(fa)才是可以的(de)，不然的(de)話(hua)是要初選(xuan)故障的(de)。當電力(li)變壓器消磁之后就不會或者是少量的(de)初選(xuan)感應現象，對于外界來說是比較(jiao)安(an)全的(de)，內部結構(gou)也是比較(jiao)穩(wen)定的(de)!
