检查机车整流装置有故障的二极管或可控硅的过程,劳动量相当大,技术维护的较大部分时间都花费在查找故障上。此外,最好有有关数控装置中所有半导体器件技术状态的可靠数据,以便能够及时更换有故障征兆的元器件。为此,布良斯克运输机械制造研究所研制了一种诊断装置,其原理如下图所示。该装置由传感器1、脉冲电压电源2、电子放大器3和测量仪表4组成。与《电力与内燃牵引》1987年第8期介绍的装置相比,本
Check the locomotive rectifier faulty diode or thyristor process, a considerable amount of labor, technical maintenance spend most of the time to find fault. In addition, it is advisable to have reliable data on the state of the art of all semiconductor devices in a numerical control installation in order to be able to promptly replace components with faulty signs. To this end, Bryansk Transport Machinery Manufacturing Institute has developed a diagnostic device, the principle as shown below. The device consists of a sensor 1, a pulse voltage power supply 2, an electronic amplifier 3 and a measuring instrument 4. Compared with the “Electric Power and Internal Combustion Traction” introduced in 1987 the eighth installment, this
