一、概述

干式(shi)鐵芯啟(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器是(shi)(shi)啟(qi)動(dong)(dong)(dong)(dong)(dong)交(jiao)流(liu)異(yi)(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)時，經常用(yong)(yong)到的一(yi)種電(dian)(dian)氣(qi)設(she)(she)(she)備。大型(xing)交(jiao)流(liu)異(yi)(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)在額定(ding)電(dian)(dian)壓(ya)下啟(qi)動(dong)(dong)(dong)(dong)(dong)時，初始電(dian)(dian)流(liu)很大，往(wang)往(wang)超過額定(ding)電(dian)(dian)流(liu)的很多倍(bei)，為了降低(di)啟(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)流(liu)，通常采(cai)用(yong)(yong)降低(di)電(dian)(dian)壓(ya)的方法來(lai)啟(qi)動(dong)(dong)(dong)(dong)(dong)交(jiao)流(liu)異(yi)(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，常用(yong)(yong)的降壓(ya)方式(shi)是(shi)(shi)采(cai)用(yong)(yong)啟(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器，使用(yong)(yong)起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器和電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)串聯，增(zeng)加電(dian)(dian)機(ji)(ji)起(qi)動(dong)(dong)(dong)(dong)(dong)回路的等效阻(zu)抗(kang)(kang)，從而減小起(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)流(liu)，減小對電(dian)(dian)網的影響。交(jiao)流(liu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的起(qi)動(dong)(dong)(dong)(dong)(dong)過程很短(一(yi)般數秒鐘(zhong)至二分(fen)鐘(zhong))，起(qi)動(dong)(dong)(dong)(dong)(dong)后就(jiu)將降壓(ya)起(qi)動(dong)(dong)(dong)(dong)(dong)用(yong)(yong)電(dian)(dian)抗(kang)(kang)器或自(zi)耦變壓(ya)器切除。本產品是(shi)(shi)根(gen)(gen)據6kV或10kV高壓(ya)異(yi)(yi)步(bu)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的起(qi)動(dong)(dong)(dong)(dong)(dong)特性設(she)(she)(she)計的啟(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器，適用(yong)(yong)范圍220KW-1400KW。也(ye)可根(gen)(gen)據用(yong)(yong)戶具(ju)體電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)的型(xing)號及要求(qiu)設(she)(she)(she)計各種啟(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)抗(kang)(kang)器。

二、結構特點

1、線(xian)圈(quan)采用(yong)真(zhen)空澆(jiao)注(zhu)，選用(yong)優質的環氧樹脂，線(xian)圈(quan)表(biao)面(mian)光滑，無裂紋、氣泡(pao)和空穴(xue)，保證產品優良的電氣性能和機(ji)械特性。

2、線圈(quan)上下端部采用環(huan)氧墊塊和硅橡膠防震(zhen)墊，有效減小運(yun)行時(shi)的震(zhen)動。

3、空氣自冷，可短時間內多(duo)次直接(jie)起動。

4、鐵(tie)芯(xin)均(jun)為三(san)柱心(xin)式結構，心(xin)柱截面均(jun)為多級圓形，心(xin)柱由若干(gan)氣隙及硅鋼片(pian)迭積(ji)的鐵(tie)餅組成用(yong)環氧(yang)樹脂澆注(zhu)，多根不(bu)銹鋼拉螺桿拉緊，并且(qie)鐵(tie)芯(xin)整(zheng)體(ti)浸(jin)漆(qi)，使產品的噪聲進一步降低。

5、電抗器外形(xing)尺寸參考(kao)標準柜體(ti)尺寸設(she)計，體(ti)積小、安裝(zhuang)方便，產(chan)品(pin)阻燃、三(san)防（即防鹽霧、防潮濕、防霉菌），可在各種環境下(xia)安裝(zhuang)使用。

三、執行標準

GB/T10229-1988《電抗器》
