1 前言我段目前共配属DF7型机车22台,分别担当着洛阳地区小运转及各编组站的调车任务。机车安装了EQDH型电子恒功调节器,它通过自动控制牵引发电机励磁机的励磁电流而自动控制牵引发电机功率,从而达到间接控制柴油机功率的目的。但随着机车的正常运用,电子恒功调节器故障越来越多。由于机车平时不入段,且机车本身不能做负载试验,只能上线跟车检查、调试,这就使得机车故障时间大大延长,甚至造成不必要的机破、临修。为此,我段早已购买了铁科院生产的电子恒功调节器试验台。但由于其中的主要部件测功测流器(11#组件)不能在试验台上进行检测、调试,使得电子恒功的许多故障(如窜车、柴油机冒黑烟、喘振等)一时得不到彻底解决,给我段的检修工作带来了被动。为此,我段自行设计研制了电子恒功测功测流器(11#组件)
1 Foreword I paragraph at present a total of 22 DF7 locomotives, respectively, responsible for the small operation in Luoyang and marshalling yard shunting tasks. Locomotive installed EQDH-type electronic constant power regulator, which automatically controls the traction generator excitation machine excitation current and automatically control the traction generator power, so as to achieve the indirect control of diesel engine power purposes. However, with the normal use of locomotives, electronic constant power regulator more and more failures. Because the locomotive usually does not enter the segment, and the locomotive itself can not do the load test, only on-line with the car inspection, commissioning, which makes the locomotive time greatly extended, or even cause unnecessary machine broken, temporary repair. To this end, I have already bought the section of the ASTRI’s electronic constant power regulator test bed. However, as one of the main components of the DFIG (11 # components) can not be detected and debugged on the test bench, many failures of electronic constant power (such as channeling vehicles, black smoke from diesel engines, surge, etc.) To completely solve, to my section of the maintenance work has brought a passive. To this end, I paragraph designed and developed by the electronic constant power measurement measuring device (11 # components)
