摘　　要：基于电流形态小波判据,建立短路故障早期检测模型,设计了基于TMS320F2812的短路故障早期检测硬件电路。运用形态学滤波和3次B样条算法,实现了短路故障快速、准确地判断,为快速切断故障电路奠定基础。Based on the morphological wavelet of current,the model of the early detection at the short circuit fault was built, then the hardware circuit of the early detection at the short circuit fault was designed based on the TMS320F2812. The morphological filter and cubic B spline arithmetic were used to realize the fast and accurate judgement at the short circuit fault. This method lays the foundation for fast disconnecting the failure circuit.
