Abstract

The invention discloses a method and system for comprehensive inspection of power equipment, and the method comprises the steps: collecting a surface temperature signal and an ultrasonic signal of detection equipment and the operation condition data of the detection equipment, and respectively generating an infrared thermal imaging image and a sound wave image based on the surface temperature signal and the ultrasonic signal; sending the infrared thermal imaging image, the sound wave image and the detection equipment operation condition data to a cloud platform for storage; compositing a positioning sound source signal in the sound wave image to the infrared thermal imaging image to generate a composite thermal image; extracting a sound wave fingerprint based on the sound wave image; and judging the fault severity of the detection equipment based on the operation condition data of the detection equipment and the composite thermal image, and judging the fault type of the detection equipment according to the sound wave fingerprint.

Description

technical field [0001] The invention relates to the technical field of live detection of key equipment in a power system, and more specifically, to a method and system for comprehensive inspection of power equipment. Background technique [0002] Power equipment is an important part of the power system. The safe and reliable operation of power equipment is of great significance to the stability and safety of the power system. With the increasingly complex structure and functions of power equipment, the status detection and fault diagnosis system of power equipment has been obtained More and more applications. It is precisely because of the continuous expansion of the distribution network scale and the continuous increase in the number of equipment, how to effectively grasp the health status of key power equipment in the distribution network has become an urgent problem to be solved in the power industry. [0003] The most intuitive and commonly used parameter to characteriz...
