Abstract

The power supply situation of the coal mine is complex, there exists problems such as short route, unable to guarantee the overcurrent set value, it is easy to cause a short circuit, electric leakage, and then electric power system leapfrog to the ground, causing blackouts underground area, production cannot be carried out. And even worse, the concentration of gas may create security issues. Therefore, the author summarizes the advantages and disadvantages of each method through the analysis of various causes of tripping in coal mine power supply system aiming at the analysis and comparison of common tripping protection system method. The results show that the digital optical fiber differential protection can effectively prevent tripping phenomenon,it has a wide application prospect.
