直流发电机是拖拉机、农用车上的主要电气设备,如果发生故障,就会影响作业进程。主要故障:一是不发电;二是电压过低;三是发电机过热。其故障原因及排除方法如下。 1.发电机不发电 (1)发电机旋转方向不对,无电流输出。此时,可调换激磁线圈接头解决。 (2)电枢或磁场绝缘接线柱的绝缘损坏,或绝缘电刷架的绝缘损坏,致使其与发电机外壳搭铁。修复
DC generator is a tractor, agricultural vehicles, the main electrical equipment, if it fails, it will affect the operation process. The main fault: First, no power generation; Second, the voltage is too low; Third, the generator overheating. The reason for the failure and troubleshooting are as follows. 1 generator is not generating (1) Generator rotation direction is wrong, no current output. At this point, you can change the excitation coil connector to solve. (2) Damage to the insulation of the armature or the magnetic field insulation post, or the insulation of the insulated brush holder, causing it to build up with the generator housing. repair
