What are the consequences of sparking from generator carbon brushes?

Consequences caused by sparks from the carbon brushes of the generator:\x0d\Slight sparks from the carbon brushes in the generator have no effect if not dealt with in time, the sparks will become bigger and bigger , causing significant heat, burning the carbon brushes and slipping. rings, causing the excitation circuit to be interrupted or the brush holder to burn. \x0d\\x0d\Generator carbon brush ignition processing methods and precautions:\x0d\1 The brushes are poorly ground and the contact area is small. The brushes must be ground or the generator must operate for a long time under low load until. Grind until it is good.\x0d\2 The connection between the brush and the lead wire, the lead wire and the terminal block is loose, and the contact resistance is large, causing uneven load distribution. Check the contact between the brush and the terminal block. copper braid and ifthe screws of the connection circuit are tight, if the contact is good.\x0d\3 The brand of the brush does not comply with the regulations, or brushes of a different brand are used. To check the brand of the brush, replace it. with the brush specified by the manufacturer or adapted after testing.\x0d\ 4 Brush pressure is uneven or does not meet requirements. Use a spring scale to check brush pressure and make adjustments (brush pressure should agree with this). manufacturer's regulations, generally 0.2 ~ 0.3 MPa). Pay special attention to making the pressure of each brush uniform.\x0d\5 The brushes are worn when the brushes are shortened to the specified value, they need to be replaced. x0d\6 Slip ring and brush surfaces are dirty. Depending on the degree of dirt, this can occur on individual brushes or on individual brushes. Sparkse produce on all brushes. Use a white cloth dampened with a little alcohol to wipe. slip ring, wipe the brush surface with a clean white cloth, and cover the grinding tool with fine sandpaper to grind the slip ring.
