单极滑触线在正常运行中应做定期检查，因为用电设备是每个工矿企业的主要生产工具，稍有差错就会直接影响工厂的生产效益。在检查滑触线时应检查每6米一个接头处是否有松动、脱开，在检查导电器时，应检查活动部位是否转动灵活，拉簧是否疲劳，电刷磨损等情况(这些情况都会影响到滑触线导电性能和导电器的跟踪性能。应及时作好调整)。
Unipolar sliding contact line to do regular checks should be in normal operation, because the electric equipment is the main tool of production of each industrial and mining enterprises, a slight error will directly affect the production efficiency of the factory. In the examination of the sliding contact line should check whether every 6 meters of a joint looseness, disengagement, check in guide of electrical appliances, should check whether the rotating flexible spring place of activity, whether fatigue, etc. (brush wear these conditions will affect the sliding contact line conducting performance tracking performance and guide appliances. Should be timely adjusted).
     节假日设备整修期，将导电器脱出导管，检查导电器电刷滚轮磨损情况，如电刷伸出量小于规定有效长度时要及时更换，导向滚轮变形严重时，亦需更换，以保持导电器运行正常和电刷的良好接触，并清查造成的原因。安全滑触线所有零部件中，电刷是唯一正常会磨损的零件。
Holiday equipment repairs, will guide electric catheter out, check the guide electric brush roller wear, such as the brush out less than the provision of effective length should be promptly replaced, the guide roller deformation is serious, also need to be replaced, in order to maintain the normal operation and guide electric brush contact is good, and the inventory of the causes. Security sliding touch line all parts, brush is the only normal wear parts.
     对于有严重腐蚀气体环境?尚需检查支架、悬吊夹、牵引器的锈蚀情况;并及时采取措施?涂上防锈材料。 滑触线使用场所?如进行基建时。切勿冲击、撞压输电导管?更不准将重物压在输电导管上。防止输电导管变形开裂?影响使用?发生安全事故。基建结束，应立即清除输电导管上的基建垃圾。 正常保养时，工作人员不准将脚踏在输电导管或其支架上，防止破坏整线的平整度及发生意外事故。
For severely corrosive gas environment? Still need the corrosion inspection frame, suspension clamp, tractor; and to take timely measures to apply anti rust material?. Sliding contact line using places such as infrastructure when?. Do not impact, hit the pressure transmission catheter? Not put heavy pressure on transmission conduit. To prevent deformation and cracking of transmission catheter? The impact of the use of safety accidents happen?. Construction ended, should immediately remove the transmission conduit infrastructure garbage. Normal maintenance, staff are not allowed to be foot in transmission conduit or on its support and to prevent the destruction of the entire line of smoothness and accident.
