1、 電刷： 應根據移動用電設備使用情況每1—3個月檢查一次。重點檢查集電器電刷的磨損情況，若磨損量≥5mm時，必須更換。檢查時若發(fā)現電刷松動或發(fā)生磨損偏斜時，應查明原因，及時處理。
1, brush: electric equipment should be based on the use of every 1 to 3 months to check the time. Focus on examination of the collector brush wear, if wear amount is greater than or equal to 5mm, must be replaced. If found loose or wear occurs when the oblique brush check, should identify the reasons, timely treatment.
  2、 集電器：至少每季度檢查一次。重點檢查緊固件有無松動、移位及塑料件和活動件磨損情況，檢查彈簧拉力（集電器電刷與導軌的接觸壓力應保持一定壓力（見下表）。發(fā)現問題及時處理。
2, the collector: at least quarterly check once a. Focus on examination of the fastener looseness, displacement and plastic piece and a movable parts wear, check the spring tension (contact pressure collector brush and guide should maintain certain pressure (see table below). Found problems timely treatment.
  3、 連接件：至少每年檢查一次。重點檢查緊固螺栓、焊縫及支撐件是否松動、銹蝕、移位等，發(fā)現問題，及時處理。
3, connector: at least once a year to check. Key check fastening bolts, welds and support is loose and corroded, shift, found the problem, timely treatment.
  4、 日常檢查：重點檢查軌道的平直度有無明顯偏差（大于20mm）、錯位，絕緣保護件有無脫落、斷裂、破損，不銹鋼“v"型槽有無翹起；軌道上有無異物及導電粉塵等。必要時應檢測其絕緣電阻是否符合要求（相間絕緣電阻應≥5MΩ）。
4, the daily check: focus on examination of rail straightness has no significant deviation (more than 20mm), dislocation, insulation protection parts are loose, broken or damaged, stainless steel "V" type groove is no tilt; orbit is free of foreign matter and conductive dust etc.. When necessary, to detect the insulation resistance is to meet the requirements (interphase insulation resistance should be greater than or equal to 5M.).
