集電器碳刷是集電器導電部分，運用粉末冶金技術，采用電解銅及其他合金材料制作的集電器銅電刷具有耐磨性好，導電率佳的特點，既保證用電設備的安全，又能有效輸送電源，同時運轉平穩，噪音小。

      集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)是滑(hua)觸(chu)(chu)(chu)線(xian)(xian)系(xi)統(tong)(tong)中(zhong)集(ji)(ji)電(dian)(dian)(dian)(dian)側拾(shi)取(qu)電(dian)(dian)(dian)(dian)能的(de)主要裝置(zhi)之(zhi)一,它(ta)(ta)通過集(ji)(ji)電(dian)(dian)(dian)(dian)刷與(yu)導(dao)(dao)軌(gui)的(de)滑(hua)動(dong)(dong)接觸(chu)(chu)(chu),將電(dian)(dian)(dian)(dian)能直接傳導(dao)(dao)至用電(dian)(dian)(dian)(dian)器(qi),從而(er)實現系(xi)統(tong)(tong)的(de)移(yi)動(dong)(dong)供電(dian)(dian)(dian)(dian)，集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)由機(ji)械(xie)結構的(de)張(zhang)力裝置(zhi)和(he)直接與(yu)導(dao)(dao)軌(gui)滑(hua)動(dong)(dong)接觸(chu)(chu)(chu)的(de)集(ji)(ji)電(dian)(dian)(dian)(dian)刷兩部分組(zu)成(cheng),機(ji)械(xie)結構的(de)張(zhang)力裝置(zhi)決(jue)定集(ji)(ji)電(dian)(dian)(dian)(dian)刷與(yu)導(dao)(dao)軌(gui)的(de)滑(hua)動(dong)(dong)接觸(chu)(chu)(chu)壓力和(he)機(ji)構的(de)穩定性,集(ji)(ji)電(dian)(dian)(dian)(dian)刷則是導(dao)(dao)軌(gui)滑(hua)動(dong)(dong)接觸(chu)(chu)(chu)拾(shi)取(qu)電(dian)(dian)(dian)(dian)能的(de)導(dao)(dao)體,它(ta)(ta)的(de)性能和(he)導(dao)(dao)電(dian)(dian)(dian)(dian)質量(liang)以及材料(liao)結構成(cheng)分的(de)優劣,將直接影響整(zheng)個系(xi)統(tong)(tong)設備的(de)安全運行質量(liang),因此集(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)是整(zheng)個滑(hua)線(xian)(xian)系(xi)統(tong)(tong)中(zhong)zui主要的(de)部件之(zhi)一。
