集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是滑(hua)觸線系統(tong)(tong)中集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)側拾取電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)(de)(de)主(zhu)要(yao)裝置(zhi)(zhi)之一,它通過集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)刷與導軌的(de)(de)(de)滑(hua)動(dong)接(jie)觸,將(jiang)電(dian)(dian)(dian)(dian)(dian)能(neng)直接(jie)傳導至用(yong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi),從而實現系統(tong)(tong)的(de)(de)(de)移(yi)動(dong)供電(dian)(dian)(dian)(dian)(dian).集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)由機(ji)械結構的(de)(de)(de)張力裝置(zhi)(zhi)和(he)直接(jie)與導軌滑(hua)動(dong)接(jie)觸的(de)(de)(de)集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)刷兩部(bu)分組成,機(ji)械結構的(de)(de)(de)張力裝置(zhi)(zhi)決定(ding)集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)刷與導軌的(de)(de)(de)滑(hua)動(dong)接(jie)觸壓力和(he)機(ji)構的(de)(de)(de)穩定(ding)性,集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)刷則是導軌滑(hua)動(dong)接(jie)觸拾取電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)(de)(de)導體,它的(de)(de)(de)性能(neng)和(he)導電(dian)(dian)(dian)(dian)(dian)質(zhi)量以及材料結構成分的(de)(de)(de)優劣(lie),將(jiang)直接(jie)影響整個系統(tong)(tong)設(she)備的(de)(de)(de)安全運(yun)行質(zhi)量,因(yin)此集(ji)(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是整個滑(hua)線系統(tong)(tong)中最主(zhu)要(yao)的(de)(de)(de)部(bu)件之一.
滑觸線(xian)集電器(qi)作為行(xing)車供電(dian)(dian)(dian)的(de)一個(ge)關鍵部件，如何選(xuan)用(yong)滑(hua)(hua)觸線(xian)(xian)(xian)(xian)集(ji)(ji)電(dian)(dian)(dian)器顯得尤為重(zhong)要， 滑(hua)(hua)觸線(xian)(xian)(xian)(xian)集(ji)(ji)電(dian)(dian)(dian)器主(zhu)要有靴片滑(hua)(hua)線(xian)(xian)(xian)(xian)、靴盒、彈簧、集(ji)(ji)電(dian)(dian)(dian)器支(zhi)架(jia)、集(ji)(ji)電(dian)(dian)(dian)器支(zhi)撐部分等部件組成。? 集(ji)(ji)電(dian)(dian)(dian)器分為重(zhong)型(xing)(xing)集(ji)(ji)電(dian)(dian)(dian)器和輕(qing)型(xing)(xing)集(ji)(ji)電(dian)(dian)(dian)器，選(xuan)擇輕(qing)型(xing)(xing)集(ji)(ji)電(dian)(dian)(dian)器還是(shi)重(zhong)型(xing)(xing)集(ji)(ji)電(dian)(dian)(dian)器，是(shi)根據滑(hua)(hua)觸線(xian)(xian)(xian)(xian)的(de)電(dian)(dian)(dian)流(liu)來(lai)確定的(de)，一般滑(hua)(hua)觸線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)流(liu)小于(yu)等于(yu)500A，可以選(xuan)用(yong)輕(qing)型(xing)(xing)集(ji)(ji)電(dian)(dian)(dian)器；大于(yu)500A的(de)，就要選(xuan)用(yong)重(zhong)型(xing)(xing)集(ji)(ji)電(dian)(dian)(dian)器。
選用(yong)滑(hua)(hua)(hua)觸線(xian)集電(dian)器(qi)(qi)的(de)時(shi)候，首選集電(dian)器(qi)(qi)最(zui)好是考慮和(he)滑(hua)(hua)(hua)觸線(xian)相配套(tao)，不要(yao)亂(luan)用(yong)集電(dian)器(qi)(qi)，否則會影響行車的(de)正常運行，嚴(yan)重了會燒壞滑(hua)(hua)(hua)觸線(xian)。集電(dian)器(qi)(qi)上面的(de)靴(xue)片(pian)(pian)是由(you)含(han)銅碳基壓制而成的(de)，購買后要(yao)檢(jian)查(cha)與滑(hua)(hua)(hua)線(xian)的(de)吻合型。由(you)于集電(dian)器(qi)(qi)本身屬于易耗品，長期使(shi)用(yong)會磨(mo)損靴(xue)片(pian)(pian)，所以要(yao)定期檢(jian)查(cha)，集電(dian)器(qi)(qi)上面靴(xue)片(pian)(pian)的(de)磨(mo)損程(cheng)度，并定期更換(huan)。
