Article Preview

Abstract:

Feeder switch of mine guarantees safe operation of underground power supply system. In order to solve the poor stability and reliability of the current mining feeder switch, the article puts forward an dual-core intelligent protection device of feed switch based on DSP. The device to TMS320C6678 as control core of measure and control module collect electrical and deal with signal analysis in the grid. The DSP make instruction of protection operation. The equipment with ATmega128 as control core of management module complete the function of setting parameters and showing results of the measurement. The experimental results show that the device movement is stability , sensitivity. The equipment is high reliability and the scheme is feasible.
