LYJD系列滑觸線集電器是滑觸線系統中集電側拾取電能的主要裝置之一，它通過集電刷與導軌的滑動接觸，將電能直接傳導至用電器，從而實現系統的移動供電。集電器由機械結構的張力裝置和直接與導軌滑動接觸的集電刷兩部分組成，機械結構的張力裝置決定集電刷與導軌的滑動接觸壓力和機構的穩定性，集電刷則是導軌滑動接觸拾取電能的導體，它的性能和導電質量以及材料結構成分的優劣，將直接影響整個系統設備的安全運行質量，因此集電器是整個滑線系統中最主要的部件之一。

滑觸線集電器作為行(xing)車(che)供電(dian)(dian)(dian)(dian)的(de)一個關鍵部件，如何選用滑(hua)(hua)線集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)顯得尤為重(zhong)(zhong)要(yao)， 滑(hua)(hua)線集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)主要(yao)有靴(xue)片(pian)滑(hua)(hua)線、靴(xue)盒、彈簧、集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)支(zhi)架、集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)支(zhi)撐(cheng)部分等(deng)部件組成(cheng)。  集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)分為重(zhong)(zhong)型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)和(he)輕型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)，選擇輕型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)還是(shi)(shi)重(zhong)(zhong)型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)，是(shi)(shi)根據滑(hua)(hua)觸(chu)線的(de)電(dian)(dian)(dian)(dian)流來(lai)確定的(de)，一般滑(hua)(hua)觸(chu)線電(dian)(dian)(dian)(dian)流小于等(deng)于500A，可以選用輕型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)；大于500A的(de)，就要(yao)選用重(zhong)(zhong)型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)。

選用(yong)滑(hua)線集電(dian)器(qi)(qi)的(de)(de)時候(hou)，集電(dian)器(qi)(qi)最好是考慮和(he)滑(hua)觸線相配套，不要亂用(yong)集電(dian)器(qi)(qi)，否則會(hui)(hui)影響行車(che)的(de)(de)正(zheng)常(chang)運行，嚴重了(le)會(hui)(hui)燒壞滑(hua)觸線。集電(dian)器(qi)(qi)上(shang)面的(de)(de)靴(xue)(xue)片是由(you)含銅碳基壓而成的(de)(de)，購買后要檢(jian)查與滑(hua)線的(de)(de)吻合型(xing)。由(you)于(yu)集電(dian)器(qi)(qi)本身(shen)屬于(yu)易(yi)耗品，長(chang)期使用(yong)會(hui)(hui)磨(mo)損靴(xue)(xue)片，所以要定期檢(jian)查，集電(dian)器(qi)(qi)上(shang)面靴(xue)(xue)片的(de)(de)磨(mo)損程度，并定期更換(huan)。
