When the brush of the diesel generator sparks, each brush group of the generator has four parallel brush columns, and each brush column is connected by a brush braid (copper resistance wire). We have to wear insulating gloves because the generator is energized. the rated voltage is 365V, and 180-200V under normal conditions, which exceeds the safety voltage of the human body. Repeatedly pull the brush braid corresponding to the sparks to adjust the brush current distribution evenly to maximize the release of spring pressure and prevent the brush column from sticking and grinding. Also, do not use too much force when pulling to prevent the braid from breaking. By the way, sparks from generator brushes rarely occur. Some comrades have never seen a sparkling broom and don't know how to deal with it. They think that the handle of the piezoelectric broomElectricity is sufficient. . The handle is fixed, installed and used to take electric brushes. You cannot push or pull the brushes. If you want to remove the brushes, hold the handle and turn it 90 degrees to the left. Then gently pull on all the brushes and remove them.
Sparking from diesel brushes is severe or several brushes are on fire. Appropriately reduce the reactive power to achieve the purpose of reducing the excitation current and reducing the operating pressure of local faulty brushes. However, it is necessary to prevent the generator excitation regulator from losing excitation in manual mode and there being high excitation in automatic mode. At this time, it is very necessary to warn the generator to reduce the active power (the reactive power will also decrease accordingly). It is true that when the generator brush produces serious sparksIts, the series of measures we take only serve to save time for maintenance.
The above is the experience brought by Weichai parts manufacturers. I hope this information is useful to you.
