Research on Detection of Transmission Line Porcelain Insulator Based on Infrared Technology

Abstract

With the continuous development of infrared technology, infrared-based detection and diagnosis technology has become a new modern power equipment detection technology. Based on infrared technology, this paper proposed detection and diagnosis method of the transmission line porcelain insulators, including analysis on detection theory of IR imaging sensor, and infrared imaging map introduction. Through establishing porcelain insulator circuit calculation model, computing heating power of trouble insulators, this paper minutely analyzed the heating causes of trouble insulators. The paper provided a reference to the detection of transmission line porcelain insulators, which made it an important measure to ensure the safety and economic operation of electrical equipment.

Obstacle distance measurement based on binocular vision for high-voltage transmission lines using a cable inspection robot

“…At present, common methods include ultrasonic ranging, 14 lidar ranging, 15 , 16 infrared ranging, and optical ranging. 17 , 18 Although the principles of the ultrasonic, lidar, and infrared ranging methods are simple and the amount of computation required is small, the equipment is expensive, the image contrast is low, and the ability to distinguish details is poor. Optical detection, which comprises monocular ranging and binocular ranging, plays an increasingly important role in achieving obstacle detection because of the rich information and high resolution.…”
