| Abstract: | The Digital Signal Processors(DSP) as the control key of the protection device is applied to design the electric leakage protection system of the electric grid in coal mine based on the DSP.The protection device lays special stress on solving the electric leakage protection of the main feeder switch and the branch feeder switch.Because of the different electric leakage places,the electric leakage protection of additional DC power type,current type and power directional mode is distributed.The leakage protection device would have reaction sensitive and reliable operation. |
