一、概述

干式(shi)鐵芯啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)是啟動(dong)(dong)(dong)交流(liu)(liu)異步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)時，經常(chang)用到的(de)(de)一種電(dian)(dian)(dian)(dian)氣設備(bei)。大型交流(liu)(liu)異步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)在額定電(dian)(dian)(dian)(dian)壓(ya)(ya)下啟動(dong)(dong)(dong)時，初始(shi)電(dian)(dian)(dian)(dian)流(liu)(liu)很大，往往超過(guo)額定電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)很多(duo)倍，為了降(jiang)低啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)流(liu)(liu)，通常(chang)采(cai)用降(jiang)低電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)方(fang)法來(lai)啟動(dong)(dong)(dong)交流(liu)(liu)異步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)，常(chang)用的(de)(de)降(jiang)壓(ya)(ya)方(fang)式(shi)是采(cai)用啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)，使(shi)用起動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)和電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)串聯(lian)，增(zeng)加電(dian)(dian)(dian)(dian)機(ji)起動(dong)(dong)(dong)回(hui)路的(de)(de)等效阻抗(kang)，從而減(jian)小(xiao)起動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)流(liu)(liu)，減(jian)小(xiao)對電(dian)(dian)(dian)(dian)網的(de)(de)影響(xiang)。交流(liu)(liu)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)的(de)(de)起動(dong)(dong)(dong)過(guo)程(cheng)很短(一般(ban)數秒(miao)鐘至二(er)分(fen)鐘)，起動(dong)(dong)(dong)后(hou)就將(jiang)降(jiang)壓(ya)(ya)起動(dong)(dong)(dong)用電(dian)(dian)(dian)(dian)抗(kang)器(qi)或自耦變(bian)壓(ya)(ya)器(qi)切除。本產品(pin)是根據6kV或10kV高(gao)壓(ya)(ya)異步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)的(de)(de)起動(dong)(dong)(dong)特(te)性設計(ji)(ji)的(de)(de)啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)，適用范圍220KW-1400KW。也可根據用戶(hu)具(ju)體電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)的(de)(de)型號(hao)及要求設計(ji)(ji)各(ge)種啟動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)抗(kang)器(qi)。

二、結構特點

1、線圈采用真空澆注(zhu)，選用優質的環氧樹脂，線圈表(biao)面光滑，無(wu)裂紋、氣泡和空穴，保證產(chan)品優良的電氣性(xing)能和機械特性(xing)。

2、線(xian)圈(quan)上下(xia)端部采用環氧墊塊和硅橡(xiang)膠防(fang)震(zhen)墊，有效減小運行時的震(zhen)動。

3、空氣自冷，可短時間內多次直接起動。

4、鐵(tie)芯均為三柱心式結構，心柱截面(mian)均為多級圓形，心柱由若干(gan)氣隙及硅鋼片(pian)迭積(ji)的(de)鐵(tie)餅組成用環氧樹脂澆注，多根(gen)不銹鋼拉(la)螺桿拉(la)緊，并且鐵(tie)芯整體浸漆，使產(chan)品的(de)噪聲進一步降(jiang)低。

5、電抗(kang)器(qi)外(wai)形尺寸參考(kao)標準柜體尺寸設(she)計，體積小、安裝(zhuang)方(fang)便，產品(pin)阻燃、三(san)防（即防鹽(yan)霧、防潮濕(shi)、防霉菌），可在各種環境下安裝(zhuang)使用。
