集電器是滑線零碎中集電側拾取電能的重要安裝，它經過集電刷與導軌的滑動接觸，將電能間接傳導至用電器，從而完成零碎的挪動供電。集電器由機械構造的張力安裝和間接與導軌滑動接觸的集電刷兩局部構成。
The collector is an important installation of slide wire system collecting side pick up electrical energy, it passes through the sliding contact brush collector and guide rail, electrical energy indirect conduction to the electric appliances, thus completing the move system power supply. The collector is installed by the mechanical structure of the tension and the indirect contact with the guide rail sliding brush collector of two parts.
      機械構造的張力安裝確定集電刷與導軌的滑動接觸壓力和機構的穩固性，集電刷則是導軌滑動接觸拾取電能的導體，它的功能和導電質量以及資料構造成分的優劣，將間接影響全部零碎設備的平安運轉質量。
Mechanical structure to determine the stability of the tension mounted sliding contact pressure and the mechanism of the brush and the guide rail set, set a brush is rail sliding contact conductor pickup of electric energy, its function and conducting quality and merits of data of structural elements, safe operation quality will indirectly affect all system equipment.
      滑觸線用于給挪動中的設備供電，由兩局部構成，滑線導軌（固定局部，與電源相接，常導軌由單長4m/根或許6米/根銜接而成），集電器（滑動局部，可在滑線軌道上或內滑動并與銅條接觸取電，集電器用于與挪動電機相連）。
The sliding contact line power supply device used to move in, composed of two parts, a slide rail line (fixed part, and is connected to a power supply rail, often by a single long 4m/ root maybe 6 meters / root cohesion and collector (sliding), local, or can be in the inner slide wire track slide and contact with the copper strip electric, collector is used for being connected with the motor).
