Research of Comprehensive Protection Device in Underground Coal Mine Lighting Power Grid
Abstract:
In view of the present our country underground lighting power grid comprehensive protection device existing problems, this paper introduces a DSP-based long distance lighting comprehensive protection device. Short-circuit protection using adaptive random setting mode. Leakage protection using additional DC measurement theory.The device has the function of cable insulation level, the network current is monitored real-time and grid parameters are displayed in turn, which make the protection system more perfect and reliable.
