Slip ring service and brush replacement

    Within a certain period of time, the generator slip ring will gradually lose its luster, be oxidized and be coated with dirt and carbon. This accumulation of contaminants leads to poor contact between the brush and the slip ring. The regulator provides a large current to support the load, trying to maintain a constant output voltage. When the resistance is high due to a dirty slip ring, the regulator provides a high voltage to obtain the same current. This causes the regulator to work hard, run hot and fail prematurely. In addition, the increased resistance causes the slip ring to have a higher temperature than normal, further exacerbating the discoloration and oxidation problems. The brush material also causes the brushes to stick to their holders and prevents current from flowing to the rotor. The answer is to keep the slip ring clean.

    Slip rings require continuous maintenance to avoid degradation of the rotating electrical connection caused by normal wear and debris. We found that one of the major causes of generator failure is slip rings, dirty or damaged slip rings and brushes. In addition, such repairs can take up to three hours to implement a solution during a large-scale blackout: make good use of our slip ring cleaning service. Instruct customers to change the brushes of the generator, clean the slip ring and reinstall it to ensure that it continues to operate normally under good performance. Your comfort and peace of mind are important to us. Contact us today to arrange brush and slip ring service.
