STUDY ON TESTING METHODS OF CARBON BRUSHES FOR ELECTRIC ROLLING-STOCKS

New testing methods of carbon brushes for rolling stocks are proposed: 1. Performance of carbon brushes refers to its non-linearity of sliding contact drop to current, so the examination of brushes must be done in a view of measurement of its non-linearity. 2. The characteristics of brushes under sliding contact is affected by humidity, so that the examination of carbon brushes must be conducted in the humidity controlled chamber. 3. Brush wear is affected by such factors as current, contact force, sparking and humidity so it is necessary to use the wear test equipment which enables to combine these factors and to analyse the effect of each factors.
