摘要
广泛应用于煤矿各种机电设备中的晶闸管相控变流器有时会因输出电压缺相而不能正常工作 ,以往的检测方法不够准确 ,检测电路复杂。设计的单片机检测系统通过检测变流器输出电压的换相周期是否正常 。
The thyristor phased-control convertor sometimes dosen't normally work because of the output voltage' incomplete phases. The prior checking methods are not too exact and the checking circuits are very complicated. In this article a new checking system based on single chip microcomputer has been designed to check whether the output voltage's phase change cycle is normal or not. So the convertor' s fault can be found out more effectively.
