东风_4型机车速度表整流二极管的烧损问题是我段多年来存在的惯性故障。据其他机务段反映,他们也存在这种问题。根据统计,速度表二极管烧损约占仪表组总碎修件数的50％。经分析,我们认为二极管烧损的主要原因是二极管过压击穿。我们比较了几个解决方案,认为更换二极管型号是一种简单易行的方案。即以2AP27型的二极管代换原来的2AP17型二极管。经过试验台试验和上车运行试验,证明效果是好的。我们于1986年6月将全段东
Dongfeng _4 locomotive speedometer rectifier diode burning problem is the existence of inertia over the years my fault. According to other locomotive depots, they also have such problems. According to statistics, the speedometer diode burning account for about 50% of the total number of pieces of broken instruments. After analysis, we believe that the main reason for the diode burning is the diode over-voltage breakdown. We compared several solutions and decided that replacing the diode model was a simple solution. 2AP27 type diode that is replaced by the original 2AP17 diode. After the test bench test and the car running test, the effect is good. We will be the whole paragraph in June 1986 East
