The invention discloses a grounding system for improving the electromagnetic compatibility of an alternating-current transmission diesel locomotive. The grounding system comprises a traction converter cabinet and a frame connected with the traction converter cabinet through a grounding wire. The frame comprises two steering frames; each bogie comprises a framework and a traction motor connected with the framework through a grounding wire. The two bogies are connected through a grounding wire; the frame is connected with a steel rail through a bearing axle box in each bogie; the traction motor in each bogie is used for driving left and right wheel pairs to rotate; and the left and right wheel pairs run on the left and right steel rails in contact with the left and right wheel pairs. By reasonably arranging the grounding points, backflow between the bogie and the steel rail can be reduced, backflow current distribution is uniform, electromagnetic interference is reduced, the electromagnetic compatibility of a locomotive is improved, and safety and reliability are achieved.
本发明公开了一种提升交流传动内燃机车电磁兼容性能的接地系统,其包括:牵引变流柜以及与其通过接地线连接的车架;车架包括两个转向架;每个转向架包括构架以及分别与构架通过接地线连接的牵引电机;两个转向架之间通过接地线连接;车架通过每个转向架中的轴承轴箱与钢轨连接;每个转向架中的牵引电机用于驱动左右轮对转动;左右轮对分别在与其接触的左右侧钢轨上运转。本发明通过合理设置接地点,可以减少转向架与钢轨之间的回流,回流电流分布较均匀,减少了电磁干扰,提高了机车电磁兼容性,安全可靠。
