【Abstract】 A design method of electrical coal drill earth leakage protection based on the technology of single-chip microcomputer is introduced.The operating value of earth leakage protection can be changed with the mains voltage,but the operating value of cables insulation resistance is held the line.And the earth leakage lockout is implemented simply and reliably by means of the software approach.Furthermore,the real time insulation situation of cables can be displayed for the convenience of cables maintenance.更多还原
