集电器是滑线零碎中集电侧拾取电能的重要安装，它经过集电刷与导轨的滑动接触，将电能间接传导至用电器，从而完成零碎的挪动供电。集电器由机械构造的张力安装和间接与导轨滑动接触的集电刷两局部构成。
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.

机械构造的张力安装确定集电刷与导轨的滑动接触压力和机构的稳固性，集电刷则是导轨滑动接触拾取电能的导体，它的功能和导电质量以及资料构造成分的优劣，将间接影响全部零碎设备的平安运转质量。
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.

滑触线用于给挪动中的设备供电，由两局部构成，滑线导轨（固定局部，与电源相接，常导轨由单长4m/根或许6米/根衔接而成），集电器（滑动局部，可在滑线轨道上或内滑动并与铜条接触取电，集电器用于与挪动电机相连）。
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).
