Abstract

The invention discloses a phased array ultrasonic detection device for inner defects of a composite insulator. The phased array ultrasonic detection device comprises a phased array probe, a phased array displayer, a phased array system unit and a system main control computer. The invention also discloses a detection method applicable to the phased array ultrasonic detection device for the inner defects of the composite insulator. The detection method comprises the following steps: 1, generating an ultrasonic signal by the phased array probe and generating a reflected ultrasonic signal when the ultrasonic signal meets the defects of the composite insulator; 2, transmitting the reflected ultrasonic signal to the phased array system unit and the system main control computer, and then transmitting data to the phased array system unit and the system main control computer; 3, processing data with the phased array system unit and the system main control computer, and then outputting a phased array scanning image with the phased array displayer; 4, determining sizes, types and positions of the inner defects of the composite insulator. The detection device and the detection method have the advantage of being capable of quickly, accurately and nondestructively detecting the inner defects of the composite insulator.

Description

technical field [0001] The invention relates to the field of electric equipment detection, in particular to a phased array ultrasonic detection device and method for internal defects of composite insulators. Background technique [0002] Insulators are responsible for supporting the transmission line, isolating the transmission line and other conductive objects, and maintaining the safe operation of the power system. The excellent performance of the insulator is closely related to the safe operation of the power system. Since the successful development of composite insulators in the 1950s, they have been widely used due to their small size, light weight, high mechanical strength, excellent pollution resistance, and high dielectric strength. At present, more than 30 countries and regions in the world are using composite insulators, especially in heavily polluted areas. By 2008, the number of grid-linked composite insulators in my country will reach 8 million. Composite insu...
