电力机车分布式逻辑控制与检测单元的研究与设计

随着机车速度的不断提高,对机车运行的可靠性、安全性及高效性提出了更高的要求,电力机车有触点继电器控制系统将越来越不适应铁路高速和重载发展的需要。本文作者开展了电力机车分布式逻辑控制与检测单元研究工作:一方面,用功率场效应管I、GBT等电力电子元器件代替中间继电器直接驱动电磁接触器等控制线圈绕组,保证各种控制命令的可靠执行;另一方面,用计算机软件实现机车各种电器的逻辑联锁关系和故障诊断,保障机车安全行驶。

Research of the distributed logic control and detecting unit of electric locomotive

Along with the continual increasing of locomotive speed,reliability,safety and high efficiency are demanded.Relay control system of the electric locomotive will be less and less adapt to the railway high speed and heavy load.The author researches the distributed logic control and detecting unit of the electric locomotive.On one hand,makes use of power MOS and IGBT electric power electronics device instead of the middle relay,on the other hand,realizes with the locomotive logic interlock and failure diagnosis by software.
