First, the trolley line is powered off
Main reasons: Brush climbing in conductors; brushes worn badly, unable to reach conductors; conductor joints not flat; single collectors used; rail joints loose.
Treatment method: detect whether the collector brush wear is serious, replace the collector brush; replace the brush and re-adjust the connection node; use double brush collector; re-tighten the connection screw.
Second, the deformation of the guide rail, the operation of the collector is blocked
Main reasons: high ambient temperature; large spacing between hangers or loose handling methods: partially insulated panels, outdoor sun visors; increased number of trolleys, correcting conductors and tightening screws.
Third, the shaking line is large during work
The main reason is that the fork cannot absorb the transmission error; the straightness of the guide rail is poor; the hanger is loose.
Treatment method: Correct the tractor so that it can absorb transmission errors freely; adjust the straightness of the guide rails; tighten the lifting rack screws.
Fourth, the brush wears fast
The main reasons are: uneven joints; excessive current carrying capacity; large spring pressure.
Treatment method: Reconnect the guide rails as required; increase the number of current collectors; replace and correct the spring pressure.
Fifth, brush side scrape
The main reasons are: brush wear, improperly positioned collectors, and excessive force transfer on the pull-out side of the tractor.
Treatment method: Replace and correct the spring pressure; replace the traction fork or correct the traction fork.
Six, spark conductor <br> <br> main reasons: poor contact with the rail surface of the brush.
Treatment method: detect the conductor joints, brush the brush properly, and ensure 60% contact area.
Seventh, the trolley wire collector has a large abnormal noise
The main reason: the current is too large; the joints are not even.
Treatment method: increase the number of collectors; re-adjust the rail connection.
Eight, slippery wire collector shell scratches
Main reasons: conductor deformation; poorly positioned collector.
Treatment method: According to the second troubleshooting, increase the hanging rack; adjust the collector.
