| Abstract: | Base on the analysis on the existing problems of the electric leakage protection systems made in China and overseas, the paper provided a selectivity electric leakage protection system for mine lower voltage electric power network base on null sequence power direction. Taking the DSP processor as the key, the paper mainly discussed the working principle, hardware and software design of the system. The site operations of the system showed the rapidity, selectivity and accuracy of the electric protection. |
