二、結構特點

1、線圈采用真空澆注，選用優質(zhi)的(de)環氧樹脂(zhi)，線圈表面(mian)光滑，無裂紋、氣(qi)泡(pao)和空穴，保證(zheng)產品優良(liang)的(de)電(dian)氣(qi)性能和機械特性。

2、線圈(quan)上下端部采用環氧(yang)墊塊和(he)硅橡膠(jiao)防震(zhen)墊，有效(xiao)減小運(yun)行(xing)時(shi)的(de)震(zhen)動。

3、空氣自冷，可(ke)短時間內多(duo)次直接起動。

4、鐵芯均為(wei)三柱心(xin)式(shi)結構(gou)，心(xin)柱截面均為(wei)多級圓形，心(xin)柱由若干(gan)氣隙及硅鋼片迭積的鐵餅組成用環(huan)氧樹脂澆注，多根(gen)不(bu)銹(xiu)鋼拉(la)螺桿拉(la)緊，并且(qie)鐵芯整體浸(jin)漆，使(shi)產品的噪(zao)聲進一步降低(di)。

5、電抗器外形尺寸參考標準柜體尺寸設計，體積小(xiao)、安裝方便，產品阻燃、三防（即防鹽霧、防潮濕、防霉菌），可在各種環境下安裝使用。
