Maintenance of Carbon Brush in Operation
1 to strengthen the daily operation of inspection and temperature measurement work
In the production site equipped with clamp ammeter and thermometer, each class measure and master each brush current and temperature, brush current balance, brush body temperature control is not greater than 80 ℃, in time to eliminate the current imbalance, film, oxidation Film, jamming and other factors, to ensure that the carbon brush in a strong balance of work.
2 The occurrence of individual carbon brush wire breakage, can reduce the excitation current to replace; ring fire, should immediately reduce the excitation current, adjust the brush current balance and then change the carbon brush.
3 to strengthen the operation and maintenance, in particular the replacement of new carbon brush and the daily cleaning, adjust the carbon brush spring pressure as balanced, although the length of carbon brush, parallel operation of the brush pressure is consistent, so that carbon brush wear reduced.
4 The use of the opportunity to stop the unit, and timely cleaning slip ring and brush the dust and grease on the slip ring in time to clear the slip ring to ensure that the carbon brush and slip ring cooling.
Precautions for Carbon Brush Replacement
1 When the carbon brushes wear to the limit line (short side is 40mm) should be replaced.
2 generator carbon brush replacement maintenance should be prepared before the following tools: insulated gloves, special wrenches, sandpaper, brushes, white cloth, flashlight.
3 should be replaced by experienced personnel as the replacement of carbon brushes when the generator must be strictly enforced operation monitoring system to prevent artificial short circuit.
4 When working, standing on the insulation pad, the staff should be particularly careful, fasten the cuff, to prevent the clothes and the wiping material is rotating part of the hanging.
5 When replacing the carbon brushes, use the same batch model as the old carbon brushes.
6 It is necessary to check the generator large shaft carbon brush or generator rotor shaft positive or negative voltage deviation (8V), the generator shaft brush should be timely maintenance or replacement, maintenance or replacement should check the generator big Axis carbon brush and generator rotor positive and negative voltage on the ground situation.
7 Replace the carbon brushes should be carried out one by one, two and more carbon brush is strictly prohibited at the same time replacement.
8 When replacing the lower carbon brush, pay special attention to prevent the carbon brush from falling off.
9 Do not touch the poles or poles at the same time with the grounding part, nor can they work at the same time.
