Abstract: Abstract：Aiming at the problem of large amount of conductive interference produced by the use of mine explosion proof frequency converter, the method can be effectively suppressed by selecting appropriate grounding modes is proposed. And experiment proves that the accurate grounding mode can make the conductive interference of the mine used frequency converter no longer through the wire to the power grid or other equipment, reduce the effect of conduction interference.
