摘　　要：为保障煤矿生产的安全性,煤矿井下低压馈电开关中必须装设过电流保护装置。文章阐述了相敏对称短路保护的工作原理,介绍了以单片机80C196KB为核心、通过相敏整流方法检测、计算功率因数的实施方案。该方案抗干扰性能好,实施电路简单。In order to ensure safety of mine production, it is necessary to install over-current protector in underground low-voltage feeder switch. The working principle of phase-sensitive short-circuit protection was presented in this paper, the executive scheme of detecting and calculating power factor by phasesensitive rectification using single-chip microcomputer 80C196KB as the centrum was introduced. The scheme has advantages of good performance of anti-interference and simple circuit.
