东风_4型内燃机车主发电机转子绝缘电阻低是个惯性质量问题。因绝缘电阻低常导致转子接地故障。例如,我厂在1986年大修的主发电机中,就有7台在与柴油机配套试验后发生转子接地,造成了很大的返工。主发电机转子绝缘电阻低,影响到机车的可靠运用,机务段的反映也较大。因此,无论是研究、设计和制造单位,还是修理和运用部
Dongfeng _4 type diesel locomotive main generator rotor insulation resistance is a low inertial mass. Low insulation resistance often leads to rotor ground fault. For example, of the main generators that I plant was overhauled in 1986, seven of them had their rotors grounded after being equipped with diesel engines and caused a great deal of rework. Main generator rotor insulation resistance is low, affecting the reliable use of locomotives, locomotive depot reflect more. Therefore, both research, design and manufacturing units, or repair and use of the Department
