按下起动按钮,起动机带动发动机曲轴旋转起动,松开按钮即完成了起动过程。但是在起动过程中,常发现电磁开关内接盘与触点粘结(柴油机车发生较多),使主回路不能切断,导致转子高速空转,引起起动机烧毁。影响蓄电池的使用寿命。此现象发现后即采取熄火、拆除搭铁线等措施也无济于事。为了解决此问题,我在机车电路中增设了电磁开关故障指示装置。经装车试用证明:指示及时、 Press the start button, the starter crankshaft engine crankshaft start, release the button to complete the start-up process. However, during the starting process, it is often found that the inner disk of the electromagnetic switch is bonded with the contacts (the diesel locomotive happens more), so that the main circuit can not be cut off, causing the rotor to idly rotate at a high speed, causing the starter to be burnt out. Affect the battery life. After this phenomenon is found to turn off the flame, dismantling the ground and other measures also helpless. In order to solve this problem, I added a magnetic switch fault indicator device in the locomotive circuit. Proved by loading trial: instructions in a timely manner,
