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車(che)供電(dian)(dian)(dian)(dian)的(de)(de)一(yi)個關鍵部(bu)件，如何選(xuan)用(yong)滑線(xian)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)顯得尤(you)為重要， 滑線(xian)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)主要有(you)靴(xue)(xue)片滑線(xian)、靴(xue)(xue)盒、彈(dan)簧、集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)支架、集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)支撐部(bu)分等(deng)部(bu)件組成(cheng)。  集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)分為重型(xing)(xing)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)和輕型(xing)(xing)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，選(xuan)擇輕型(xing)(xing)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)還(huan)是(shi)重型(xing)(xing)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，是(shi)根據滑觸(chu)線(xian)的(de)(de)電(dian)(dian)(dian)(dian)流來確定的(de)(de)，一(yi)般(ban)滑觸(chu)線(xian)電(dian)(dian)(dian)(dian)流小于(yu)等(deng)于(yu)500A，可以選(xuan)用(yong)輕型(xing)(xing)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)；大于(yu)500A的(de)(de)，就(jiu)要選(xuan)用(yong)重型(xing)(xing)集(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)。

選用(yong)滑(hua)線集(ji)(ji)電器(qi)(qi)的(de)(de)時(shi)候，集(ji)(ji)電器(qi)(qi)最好是(shi)考慮和滑(hua)觸線相配套，不要亂用(yong)集(ji)(ji)電器(qi)(qi)，否則會(hui)影(ying)響行(xing)車(che)的(de)(de)正(zheng)常運行(xing)，嚴重了會(hui)燒(shao)壞滑(hua)觸線。集(ji)(ji)電器(qi)(qi)上面的(de)(de)靴片是(shi)由含銅碳(tan)基壓而成的(de)(de)，購買后要檢(jian)查(cha)(cha)與滑(hua)線的(de)(de)吻合(he)型。由于集(ji)(ji)電器(qi)(qi)本(ben)身屬于易耗品，長期使(shi)用(yong)會(hui)磨損靴片，所以要定期檢(jian)查(cha)(cha)，集(ji)(ji)電器(qi)(qi)上面靴片的(de)(de)磨損程度，并定期更換。
