一、概述

干式(shi)鐵芯啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器(qi)是(shi)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)交(jiao)(jiao)流(liu)異(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)時，經常(chang)(chang)用(yong)(yong)到的(de)(de)一種電(dian)(dian)氣設備。大型交(jiao)(jiao)流(liu)異(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)在額(e)定電(dian)(dian)壓(ya)下啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時，初始(shi)電(dian)(dian)流(liu)很大，往(wang)往(wang)超過額(e)定電(dian)(dian)流(liu)的(de)(de)很多倍，為(wei)了降低啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)流(liu)，通常(chang)(chang)采用(yong)(yong)降低電(dian)(dian)壓(ya)的(de)(de)方(fang)法來啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)交(jiao)(jiao)流(liu)異(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，常(chang)(chang)用(yong)(yong)的(de)(de)降壓(ya)方(fang)式(shi)是(shi)采用(yong)(yong)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器(qi)，使用(yong)(yong)起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器(qi)和(he)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)串聯，增加電(dian)(dian)機(ji)(ji)起(qi)動(dong)(dong)(dong)(dong)(dong)回路的(de)(de)等效阻抗(kang)(kang)，從而減(jian)小起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)流(liu)，減(jian)小對(dui)電(dian)(dian)網的(de)(de)影響。交(jiao)(jiao)流(liu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)起(qi)動(dong)(dong)(dong)(dong)(dong)過程很短(duan)(一般數(shu)秒鐘至二分鐘)，起(qi)動(dong)(dong)(dong)(dong)(dong)后(hou)就將(jiang)降壓(ya)起(qi)動(dong)(dong)(dong)(dong)(dong)用(yong)(yong)電(dian)(dian)抗(kang)(kang)器(qi)或(huo)自耦變壓(ya)器(qi)切(qie)除(chu)。本產品是(shi)根(gen)據(ju)6kV或(huo)10kV高壓(ya)異(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)起(qi)動(dong)(dong)(dong)(dong)(dong)特性(xing)設計的(de)(de)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器(qi)，適用(yong)(yong)范圍220KW-1400KW。也可根(gen)據(ju)用(yong)(yong)戶具體電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)型號及要求設計各種啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器(qi)。

二、結構特點

1、線圈(quan)采(cai)用真(zhen)空澆注，選(xuan)用優質的環氧樹脂，線圈(quan)表面光滑，無裂紋、氣泡和空穴，保證產品優良的電氣性(xing)能和機械(xie)特性(xing)。

2、線圈上下端部采用環(huan)氧墊塊和硅橡膠防震(zhen)墊，有效(xiao)減小運(yun)行(xing)時的震(zhen)動。

3、空氣自冷(leng)，可短時間內多次直接起動。

4、鐵(tie)芯(xin)均為三柱心式結構，心柱截面(mian)均為多級圓形，心柱由若干氣隙及(ji)硅鋼片迭積的鐵(tie)餅組成用(yong)環氧樹(shu)脂澆(jiao)注，多根不銹鋼拉螺(luo)桿(gan)拉緊(jin)，并且鐵(tie)芯(xin)整(zheng)體浸漆(qi)，使產品的噪聲進(jin)一步降低。

5、電抗(kang)器外形尺寸參考標(biao)準柜體尺寸設計，體積小、安(an)裝方便(bian)，產品阻燃、三防（即(ji)防鹽(yan)霧、防潮濕、防霉(mei)菌），可在各種環境下安(an)裝使用。
