An on-line monitoring device for detecting, analyzing and continuously monitoring the internal discharge signals of high-voltage switchgear and the temperature rise at the cable heads, contacts, busbars, etc. of the switchgear

Passive non-contact UHF sensor is used for partial discharge monitoring, passive wireless temperature sensor is used for temperature rise monitoring, and integrated design of partial discharge and temperature rise monitoring is used for main unit

Meet the partial discharge monitoring and positioning under the operating state of the switchgear, and upload the monitoring data to the remote background in real time to realize online diagnosis and early warning of the insulation state of the switchgear
