The invention relates to a
monitoring system, and especially relates to an antitheft type multifunctional
wireless high-
voltage cable sheath grounding current
monitoring system. The
system comprises a
monitoring system, an acquisition
system, a grounding box, a cable anti-
cut-theft alarm and current transformers, wherein the acquisition
system is respectively connected with a high-
voltage cable A phase, a high-
voltage cable B phase and a high-voltage cable C phase through the current transformers and the cable anti-
cut-theft alarm , the high-voltage cable A phase, the high-voltage cable B phase and the high-voltage cable C phase are respectively connected with the grounding box through the cable anti-
cut-theft alarm and the current transformers, the acquisition system is connected with the grounding box through the cable anti-cut-theft alarm, and the acquisition system sends information to the monitoring system through a
wireless network. According to the invention, cable main insulation aging or defects, oversheath multipoint grounding faults, cross
interconnection connection errors, direct grounding failure, protection grounding short circuits and grounding box thefts can be discovered, network nodes are regularly detected, and link faults are automatically diagnosed.
