關于滑觸線每年的檢查工作：
About sliding contact line annual inspection work:
1、檢查集電器電刷繃簧壓力應正常，一般1.8-2.3N/Cm2。
1, check the collector brush spring pressure should be normal, average 1.8-2.3 N/Cm2.
2、經過一年的運用滑觸線的導管內一般積塵都會許多，可用壓縮空氣吹氣，或用潔凈回絲擦拭。
2, after a year of using sliding contact line of intraductal general dust will be a lot of, can use compressed air to blow, or use the waste to wipe clean.
3、檢查導管有否明顯變形、彎曲，選用調整懸掛螺栓方位方法進行校直。如有彎曲，變形等表象可檢驗校直，如無法校直應立馬更換，阻止在此運用。
3, check the catheter has obvious deformation, bending, selects the adjustment hanging bolt location method for alignment. Such as bending, deformation and surface inspection alignment, such as not alignment should be replaced immediately, stop the use.
4、從導管端部取下滑觸線集電器，接插電刷磨損有否超越有用長度刻度線并及時更換，檢查頸部磨損情況。
4, falling from the catheter end wire collector, plug brush wear ever beyond useful to change in time, the length of the calibration and check the abrasion of the neck.
5、檢查滾輪磨損情況。滾輪可保證電刷在導管中上下左右方位，滾輪磨損過多，將使電刷被擦傷或發生斷電表象，電刷屬易耗物品，需要經常檢查，及時更換。
5, check the wheel wear. Roller ensures brush up and down or so in the catheter bearing, roller wear too much, will make the brush abrasion or blackouts appearances, brush consumable items, need to check, change in time.
6、檢查導管，導軌街頭如有松動、銹蝕應技能更換，檢查懸吊夾、固定夾是不是松動。

6, check the catheter, guide the street such as loose, rust should change skills, check the suspension clamp, clamp is loose or not.
