And for generator carbon brush and slip ring, under the exciting current arcing, anodal surface local is scorching hot and evaporate " metallic vapour ", makes anodal surperficial deterioration, and this cries " anode evaporation "; Negative pole also wrecks negative terminal surface because being subjected to cation bump and high temperature action emission electronics, and this cries " negative electrode efflorescence ".
Carbon brush can occur the polarity difference with slip ring because the sense of current is different.When electric current flows to slip ring by carbon brush, this moment, carbon brush was anodal, slip ring is negative pole, then the result is the anode evaporation that small degree takes place on the carbon brush face, carbon granules, graphite ion are moved to the slip ring surface, and carbon brush has electric wearing and tearing, and there is slight negative electrode efflorescence on the slip ring surface, and adhere to carbon granules, graphite, become minute surface lubricated, gloss.This moment the slip ring surface smoothing, mechanical wear is less.
When electric current flowed to carbon brush by slip ring, this moment, carbon brush was negative pole, and slip ring is anodal, and then the negative electrode efflorescence takes place on the carbon brush face result, and electric wearing and tearing are little, and the anode evaporation takes place on the slip ring surface.A large amount of evaporation of metal make its surperficial deterioration serious, and simultaneously, these metallics also easily invest on the carbon brush wear surface, can make commutator face heavy wear conversely, streak occurs.In this case, the slip ring rough surface is metal polish, and mechanical wear is big.
Because generator operation is change poles not for a long time, can cause the wearing and tearing of collector ring both positive and negative polarity inhomogeneous, might cause problems such as the increase of excitation carbon brush grade of spark, the rising of carbon brush slip-ring temperature, exist certain potential safety hazard.
