1、导轨变形，集电器运行受阻guide rail deformation, set electrical operation blocked主要原因是环境温度太高，提挂架间距离大或者松脱。The main reason is that the ambient temperature is too high, the distance between the rack provided or loose.处理方法值主要是具备使用隔热板，室外加上遮阳板，增加滑触线提挂架数量，纠正导体并拧紧螺丝。Processing method of value is mainly with the use of insulation board, outdoor sun visor, increase sliding contact line provided the number of rack, correct conductor and tighten the screws.
2、电刷磨损快brush wear fast主要原因：接头不平整；载流量过大；弹簧压力大。Main reason: the connection is not smooth; the load flow is too big; the spring pressure is big.处理方法：按要求重新连接导轨；增加集电器数量；更换、修正弹簧压力。Methods: to re connect the guide rail as required; to increase the number of sets of electrical appliances; replacement, correction spring pressure.
3、滑触线断电sliding touch line power主要原因是电刷在导电过程中爬坡，电刷被磨损太严重，不能触及到导体，导体接头不平整，单集电器使用，导轨接头松脱。The main reason is that the brush in the conductive process climbing, brush is too serious to be worn, can not touch the conductor, conductor connection is not smooth, single set of electrical appliances, guide rail joint loose.处理方法主要是检测集电器电刷磨损是否严重，更换集电器电刷，更换重新调整连接节点，使用双刷集电器，重新调整拧紧连接螺丝。The processing method is mainly to detect whether the brush wear of the collector is serious, the replacement of the electric brush, the replacement of the re adjustment of the connection node, the use of dual brush set appliances, re adjust the screw connection.
4、工作时安全滑触线晃动较大the work of sliding touch line larger主要原因是拔叉无法吸收传动误差，导轨直线度交叉，提挂架松动。The main reason is the fork to absorb the transmission error, straightness cross, hanging loose.华宝滑线提醒处理方法：修正牵引器，使之能自由吸收传动误差，调整导轨直线度，拧紧提挂架螺丝。Processing method: fixed traction device, which can adjust the transmission error free absorption, straightness, tighten the screws provided rack.
5、电刷侧面擦伤brush side scratches主要原因：电刷磨损，集电器定位不正；牵引器的拔叉侧力传递过大。The main reason: the brush wear, the electric appliance positioning is not correct; the pulling fork side force transmission is too large.处理方法：更换、修正弹簧压力；更换牵引拔叉或修正牵引器拔叉。Method of treatment: replacement, correction of spring pressure; replacement of traction fork or correction of the tractor pull fork.
6、导体内有火花the conductor has a spark主要原因：电刷表面与导轨接触不良。Main reason: the contact between the brush surface and the guide rail is poor.
