东风型内燃机车的控制回路接地,是较常见的一种故障。若不及时查找排除,多点接地以后,将会造成电器误动作,甚至造成意想不到的后果。以前,我们在找接地时发现,控制回路一处接地。往往许多条负线同时反映接地。但究竟接地点在哪条负线的回路内,心中无数,只 Dongfeng diesel locomotive control circuit ground, is a more common fault. If you do not find out in time, after more grounding, it will cause electrical malfunction, or even unexpected consequences. In the past, when we looked for a ground connection, we found that the control loop was grounded. Often many negative lines reflect ground simultaneously. But what grounding point in which loop negative circuit, the heart countless, only
