电磁涡流刹车的断电保护电路设计

Design of eddy current brake control systems with power off protective circuits

文章提出 ,涡流刹车断电保护不仅是交流电源断电需要保护 ,而且应该对造成涡流刹车失控故障的任何环节都要进行保护。这些环节应包括 3 80V交流电源、整流变压器、快速熔断器、可控硅主电路、可控硅触发电路、信号处理电路、司钻开关、刹车线圈 ;主控连接电缆。文章分析了国内外现有的断电保护电路存在的问题 ;在分析了各保护环节的逻辑关系的基础上 。

This paper discusses the problem of existing protect circuit at the time of eddy current brake power off, introducing new thought and circuit of protect circuit for eddy current brake. Not only AC power off need protection ,but also for any out of control caused by any problems, including AC power power transformer,fuse,commutate circurt,fire circuit,control circuit,driller’s control,coil,power cable and control cable.
