Study of Intelligent Robot for Insulators Based on Electric Field Method

Abstract

Insulators are used for insulation and support of power lines. For this reason, the inspection is necessary to improve the reliability of the live-line. This paper aims to solve some key technical problems of insulator string detection in overhead transmission line, and designs an insulator string detection robot with good performance and suitable for transmission line environment in china. The quality criteria of insulators for the deep research of W and electric power industry standard insulators and the existing detection methods; the insulator string at the same time to carry out resistance detection, field detection, visual inspection and hydrophobicity detection, to achieve a comprehensive evaluation of the performance of porcelain insulator. The method can comprehensively reflect the insulator state and reduce the misjudgment probability of insulator detection. Realize remote data remote control of robot, remote video real-time transmission, and analysis and storage of measurement value. Through the research on electromagnetic interference of UHV 1000kV voltage level, put forward the robot control interface circuit, multilayer shielding shell photoelectric isolation and control system and the robot is such measures, successfully overcome the electromagnetic interference problem. The application of the insulator string detecting robot reduces the skillful labor intensity of the insulator string detection, ensures the stability and reliability of the power grid operation, and promotes the development of the power robot technology and the construction of the smart grid.
