Research on porcelain pillar insulator cracking detection system based on vibrational acoustics

Porcelain pillar insulators are one of the basic equipment for operation and management of substations and power plants. The quality of practical work directly affects the safety performance of power grid system. Therefore, in the innovation and development of electric power industry, researchers have proposed a variety of detection methods and operating systems based on practical work experience. In this paper, based on the understanding of the application principle and the principle of vibroacoustics of ceramic prop insulators, and according to the status quo of actual research technology development, the cracking detection system of ceramic prop insulators with vibroacoustics as the core is deeply explored. The final experimental results show that this system can help the staff to conduct a comprehensive survey of cracking problems of porcelain pillar insulators. The actual detection efficiency is high, the application range is wide, and the labor intensity is low, which meets the requirements of substation construction management in the new era.
