DJS-150型机车速度表的测速发电机,因特性存在差异,对于同一个速度读数,其对应的三相交流电压值有较大的差异。备品试验台无法完全模拟各台机车上测速发电机1CF的实际工作状态,在试验台上整定值校验合格的电子式过渡装置,装车后自动过渡点不一定都符合段规要求。架修的机车,自动过渡点是在试运中再调整的,且因受运行条件的限制,只能调整吸合值,无法调整释放值。定修机车的过渡点,库内也无法进行车上检查调整。目
DJS-150 locomotive speedometer tachogenerator, due to differences in characteristics, for the same speed reading, the corresponding three-phase AC voltage values are quite different. The spare test bench can not fully simulate the actual working state of the tachogenerator 1CF on each locomotive. The electronic transitional device with the calibrated value on the test bench is verified, and the automatic transition point after loading may not all meet the requirements of the section gauge. Overhaul locomotive, automatic transition point is re-adjusted during commissioning, and due to operating conditions, only adjust the pull-in value, can not adjust the release value. Fixed locomotive transition point, the library can not be checked on the car adjustment. Head
