摘要
针对水阻试验台和传统的干阻试验台的不足,提出了采用新型大功率电力电子开关元件IGBT设计一种新型的干阻负载试验台,在负载调节上采用权电阻的方式实现机车主电流的连续调节,测控系统利用工业控制计算机的集散控制方式来满足实际的生产需要。
Aiming at the defect of water-resistance test bed and traditional dry-resistor load test bed,this paper brings forward a design of new dry-resistor load test bed which adopts new high-power electronic switch element IGBT.The weighting resistor was adopted to realize precise adjustment of the main current,and actual need of production was met by using collective and distributive control mode of industrial control computer.
