Abstract
The utility model discloses an on-line insulation monitoring device for a high-voltage cable. The device comprises a micro current sensor for monitoring leakage current of the high-voltage cable and a voltage sensor for extracting voltage signals from two secondary sides of a voltage transformer, wherein the micro current sensor is sleeved on the cable; signals collected by the micro current sensor and the voltage transformer are transmitted to a microcomputer controller via a shielded twisted pair cable; and the microcomputer controller reflects cable parameters via a display module. With the on-line insulation monitoring device for the high-voltage cable, the insulation state of a high-voltage power cable can be monitored in real time, pre-diagnosis and warning can be effectively carried out, occurrence of fault disasters can be prevented, loss is reduced, maintenance cost is reduced, fault rate is reduced, and the equipment outage time is reduced.
