一、概述

干(gan)式鐵芯啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)是(shi)啟(qi)(qi)動(dong)(dong)(dong)(dong)交(jiao)(jiao)流異(yi)(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)時，經常(chang)用(yong)到的(de)一種(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣設備。大型(xing)交(jiao)(jiao)流異(yi)(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)在(zai)額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下啟(qi)(qi)動(dong)(dong)(dong)(dong)時，初始電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流很大，往往超(chao)過額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)很多(duo)倍，為了降(jiang)低(di)啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，通常(chang)采用(yong)降(jiang)低(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)方法來啟(qi)(qi)動(dong)(dong)(dong)(dong)交(jiao)(jiao)流異(yi)(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)，常(chang)用(yong)的(de)降(jiang)壓(ya)(ya)方式是(shi)采用(yong)啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)，使用(yong)起(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)串聯，增加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)起(qi)動(dong)(dong)(dong)(dong)回路的(de)等效阻抗(kang)(kang)，從而減(jian)小起(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，減(jian)小對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網的(de)影(ying)響。交(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)起(qi)動(dong)(dong)(dong)(dong)過程很短(一般數(shu)秒(miao)鐘(zhong)(zhong)至二分(fen)鐘(zhong)(zhong))，起(qi)動(dong)(dong)(dong)(dong)后(hou)就將(jiang)降(jiang)壓(ya)(ya)起(qi)動(dong)(dong)(dong)(dong)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)或自耦變壓(ya)(ya)器(qi)切(qie)除。本產品是(shi)根據6kV或10kV高壓(ya)(ya)異(yi)(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)起(qi)動(dong)(dong)(dong)(dong)特性設計(ji)的(de)啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)，適用(yong)范圍(wei)220KW-1400KW。也(ye)可根據用(yong)戶具體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)型(xing)號(hao)及要求(qiu)設計(ji)各(ge)種(zhong)(zhong)啟(qi)(qi)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)。

二、結構特點

1、線(xian)圈(quan)采用真(zhen)空澆注，選(xuan)用優(you)質的環(huan)氧樹(shu)脂，線(xian)圈(quan)表面光滑，無裂紋、氣泡和(he)空穴，保(bao)證產品優(you)良的電氣性能和(he)機(ji)械特性。

2、線(xian)圈上(shang)下端部(bu)采用環(huan)氧(yang)墊塊和硅橡膠(jiao)防震墊，有效減(jian)小(xiao)運行時的震動。

3、空氣(qi)自(zi)冷(leng)，可短時(shi)間內多次直接起動。

4、鐵(tie)芯(xin)均(jun)為(wei)三柱(zhu)心(xin)式結(jie)構，心(xin)柱(zhu)截(jie)面均(jun)為(wei)多級圓形(xing)，心(xin)柱(zhu)由若干氣隙及硅(gui)鋼片迭積的鐵(tie)餅組成用環氧樹脂(zhi)澆注，多根(gen)不銹鋼拉(la)螺桿拉(la)緊，并(bing)且(qie)鐵(tie)芯(xin)整體浸漆，使產品的噪聲進一步降(jiang)低。

5、電(dian)抗器(qi)外(wai)形尺寸參考標(biao)準柜(ju)體尺寸設計，體積小、安裝(zhuang)方便，產品阻燃、三防(fang)（即防(fang)鹽霧、防(fang)潮濕(shi)、防(fang)霉(mei)菌），可在各種(zhong)環(huan)境下安裝(zhuang)使用。
