Abstract: In order to solve the problem of incorrect or missing wire diameter information which brings inconvenience to maintenance operation,a long-distance wire diameter tester based on pulse ray has been developed. Through on-site research, the range of wire diameters for different voltage levels was obtained, and a distance and wire diameter measurement sensor based on laser pulse ray principle was selected.In addition, this article designed circuit and system for a long-distance wire diameter tester based on pulse ray by using the methods of the Internet of Things and geometric principles. Through the integrated design, three ranging sensors are arranged on the sliding guide rail, which is convenient for field personnel to adjust the measurement and carry. After on-site testing at the substation, the measured data is consistent with the recorded data in the ledger. The measurement results show that the designed pulse ray based long-distance wire tester meets the requirements of fast, safe, and accurate measurement of wire diameter on site, and improves the efficiency of on-site maintenance operations.
Key words: power transmission and transformation engineering; wire diameter; pulse ray; long-distance measurement; laser ranging
