HXD1B型电力机车C4修低压调试一般包括七大项工序:蓄电池及控制电源试验、照明检查、受电弓试验、主断路器试验及扳键开关及控制手柄检查、机车保护功能测试、库内辅机测试及辅助设备试验以及库内动车试验。理论上,低压调试的计划作业时间为两天,实际作业可缩减到半天的时间。这为HXD1B型电力机车整个C4修程,节省了不少停时,使机车验交的期限得到充裕的保障。 HXD1B electric locomotive C4 repair low pressure test generally includes seven major processes: battery and control power supply test, lighting inspection, pantograph test, the main circuit breaker test and pull key switch and control handle inspection, locomotive protection function test, library auxiliary Machine test and auxiliary equipment test and the car test in the library. In theory, low-voltage debugging scheduled work time of two days, the actual work can be reduced to half a day’s time. This is the HXD1B-type electric locomotives throughout the C4 repair, saving a lot of stoppage time, so that the deadline for locomotives to get sufficient protection.
