用可控硅时间继电器作1SJ的东风4型内燃机车,若出现延时过长的故障,检修师付在测试调整时往往需要反复按起动程序闭合1QA。这样RBD和QBD须经历数次运转,增加了蓄电池的额外消耗,同时也妨碍其他检修工作的进行,这对蓄电池的保养和缩短运用机车的库仃时间均不利。若采取垫QC主触头断开各保险的方法,需要增加人。为了解决上述问题,我们进行反复摸索,终于找到了一种判别、调整1SJ的简易方法。现介绍于下,供同
With SCR time relay for the 1SJ Dongfeng 4 diesel locomotive, if the delay is too long fault, the maintenance division paid to test the adjustment often need to press the start sequence to close 1QA. This RBD and QBD to be run several times, increasing the battery additional consumption, but also prevent other maintenance work carried out, which battery maintenance and shorten the use of the locomotive library Dingding time are adverse. If you take the main contact pad QC cut off the insurance method, you need to increase people. In order to solve the above problems, we conducted repeated groping and finally found a simple method of discriminating and adjusting 1SJ. Now introduced in the next, for the same
