High voltage direct current distribution insulation against ground monitoring device

The utility model discloses a high voltage direct current distribution insulation against ground monitoring device, including the electric leakage signal acquisition element that can gather the electric leakage signal based on the high voltage direct current distribution insulation against ground part of treating the monitoring, can based on electric leakage signal acquisition element gathers gained electric leakage signal and handles and send the singlechip of intervening the signal, and can under the control of singlechip, because the output device of corresponding intervention operation is carried out to the intervention signal that the singlechip sent. High voltage direct current distribution insulation against ground monitoring device can overcome that the operational reliability hangs down, safeguards the big and security subalternation defect of the degree of difficulty among the prior art to realize that the operational reliability is high, maintain the advantage that the degree of difficulty is little and the security is good.
