Abstract

The present invention relates to a method for acceptance of an electricity inspection and expansion project, and the method is specifically as follows: when arriving at a pole-mounted transformer to be accepted, an inspection personnel holds a detection device, raises the acceptance detection device, and collects information of the pole-mounted transformer; the detection device obtains image information of the pole-mounted transformer through a camera, and obtains current temperature information of the pole-mounted transformer through an infrared thermal imager detector; the detection device sends the collected information to a cloud server, and performs transformer model identification on the cloud server and selects a temperature simulation model matching the transformer model; the simulation model is corrected according to the current temperature information, and a corrected temperature model is obtained; through the corrected temperature model, the internal temperature of the transformer is obtained, the working state of the transformer is judged, and the current temperature model of the transformer is recorded and archived. The present invention improves work efficiency, enhances safety, and can perform more accurate detection and diagnosis.
