The invention discloses a partial discharge and temperature monitoring circuit and device, and relates to the technical field of detection circuits. The partial discharge and temperature monitoring circuit comprises a main control module, a partial discharge detection module, a partial discharge alarm module, a live detection module, a live indication module, a temperature detection module and a switch control module. Wherein the main control module is electrically connected with the partial discharge detection module, the partial discharge alarm module, the live detection module, the live indication module, the temperature detection module and the switch control module. According to the partial discharge and temperature monitoring circuit, the partial discharge detection module and the electrification detection module are arranged, so that the partial discharge and high-voltage electrification conditions in equipment can be monitored in real time, and feedback is made through the partial discharge alarm module and the electrification indication module, so that a worker can know and process fault information in time; and the conditions of equipment damage and the like are avoided.
Description
technical field [0001] The invention relates to the technical field of detection circuits, in particular to a partial discharge and temperature monitoring circuit and device. Background technique [0002] Ring network switchgear, cable branch box, box-type transformer and other primary switchgear, when the internal line failure occurs, partial discharge, high voltage live, cable short circuit or grounding and other phenomena occur, it is easy to cause equipment damage and cause safety accidents. Therefore, it is necessary to monitor these switchgears in real time to prevent the occurrence of partial discharge and high-voltage electrification, and to find out the fault point and deal with it in time. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a partial discharge and temperature monitoring circuit and device, which can monitor partial disc...
