Description
technical field [0001] The invention relates to the field of fault diagnosis of electrical equipment, in particular to a temperature rise and partial discharge detection device based on ZigBee. Background technique [0002] When electrical equipment fails, it often manifests as abnormal temperature of relevant parts or partial discharge. Therefore, the detection of temperature rise and partial discharge of electrical equipment can determine whether the equipment is faulty, so as to repair and replace electrical equipment in time, which is of great significance to improve the stability of the power system. [0003] In order to detect the failure of electrical equipment, the current common methods are: built-in temperature sensor in the switch cabinet, and transmit temperature data through wireless communication to realize the monitoring of temperature rise; use infrared photoelectric sensor to detect equipment temperature rise; use ultraviolet photoelectric sensor and TEV sen...
