Research and Application of Electrical Main Equipment Status Detection Based on Non-Contact Ultrasonic Measurement Principle

Electrical equipment is an important component of the power system, and its status detection and monitoring have become key links in ensuring stable system operation and preventing accidents. Under the long-term action of alternating electromagnetic fields, power equipment will generate acoustic signals, and the changes in acoustic signals of abnormal electrical equipment can reflect the internal operating status of the equipment, as well as specific defects or faults. Non contact ultrasonic measurement technology has a wide range of application prospects in the state detection of electrical main equipment due to its non-contact, non-destructive, and safe and harmless characteristics. In specific applications, this article verifies the effectiveness of this technology in detecting the insulation status, mechanical fastening, and internal defects of electrical main equipment. The state detection method for electrical main equipment based on non-contact ultrasonic measurement principle proposed in this article provides a new technical means for the safe and stable operation of electrical equipment, which is helpful for detecting and locating abnormal sound waves in electrified power equipment, and helps on-site maintenance personnel accurately grasp the operating status of electrical equipment.
