立體三角形卷鐵芯油浸式變壓器

　　立體(ti)三(san)角(jiao)形(xing)卷(juan)鐵(tie)(tie)芯(xin)油浸式(shi)變(bian)壓(ya)器(qi)不同于傳統的(de)平面疊片式(shi)鐵(tie)(tie)心變(bian)壓(ya)器(qi)。其鐵(tie)(tie)心是由(you)單框(kuang)片立體(ti)三(san)角(jiao)形(xing)布置的(de)三(san)相柱(zhu)軛組成(cheng)。每個柱(zhu)體(ti)由(you)優(you)質(zhi)冷軋硅鋼薄(bo)帶連續卷(juan)制，帶寬經(jing)(jing)數控開料機作(zuo)直(zhi)線(xian)(xian)或曲線(xian)(xian)剪(jian)切(qie)。帶料在(zai)鐵(tie)(tie)心卷(juan)繞(rao)機上(shang)卷(juan)繞(rao)組成(cheng)近圓形(xing)或折邊圓弧框(kuang)片后經(jing)(jing)真(zhen)空充氮退(tui)火處理以消(xiao)除加(jia)工應力(li)，晶(jing)格(ge)重(zhong)新取(qu)向、提高導磁率，改(gai)善電磁性(xing)能(neng)；高低(di)壓(ya)線(xian)(xian)圈使用(yong)專用(yong)繞(rao)線(xian)(xian)機，直(zhi)接在(zai)鐵(tie)(tie)心柱(zhu)紙筒上(shang)繞(rao)制，整體(ti)結(jie)構堅實緊(jin)湊，器(qi)身采用(yong)上(shang)下鐵(tie)(tie)軛絕緣和層壓(ya)木，四(si)周拉(la)螺(luo)桿拉(la)緊(jin)線(xian)(xian)圈，使之穩固(gu)牢靠，能(neng)承受(shou)突發(fa)短路時的(de)沖擊力(li)。
