Online fault monitoring device for high-voltage cable joint

Abstract

The invention relates to the technical field of high-voltage wire detection, in particular to a high-voltage cable joint online fault monitoring device which comprises a joint wire box, the top of the joint wire box is fixedly connected with a box cover through a clamping piece, a high-voltage cable is arranged in an inner cavity of the joint wire box, and the right side of the high-voltage cable penetrates through the right side of the joint wire box. The left side of the high-voltage cable is fixedly connected with a cable connector. High-voltage cables of different models and different thicknesses can be stably fixed through the wire harness mechanism, monitoring is conducted through the monitoring head, when the monitoring head detects a fire source signal, the fire extinguishing device module is immediately triggered, rapid power failure is achieved, the fire extinguishing device is started to conduct fire extinguishing operation, and the heat dissipation mechanism is automatically started to dissipate heat in the device. In the fault monitoring process, external force impact detection is carried out on the high-voltage cable through contact between the external force impact detection protruding head and the high-voltage cable, and whether the high-voltage cable is impacted by abnormal external force or not is accurately judged.
