Application of new technologies to open shipment inspection mode
“Attendance time is up.†220 kV Jia Fengan converted to transport and maintenance staff Xiao Hu while chanting while he opened the intelligent patrol robot control platform on the computer: “Well, 'Ah Q'' star Aberdeen’’s plan to visit In the middle, 'M Bean' was sleeping (charging).†After confirming that none of the six robots within 50 kilometers of the squad’s jurisdiction had any abnormalities, Xiao Hu began routine shifts every day before the shift—a smart patrol robot inspection report. Inspection and analysis, he likes to call this part "batch assignments." Soon after, he discovered that there was an alarm message in the A Q patrol report of the 220 kV Qingshi County, and the infrared temperature measurement result of the 110kV Qingyong 1334 line of Qingshi Transform indicated that the three-phase contrast was abnormal.
After confirming the robot inspection information, the team members rushed to the Qingshi Substation 43 km away with an infrared tester, and conducted in-depth diagnostic analysis on the heat information discovered by Xiao Q. Due to the increased load of Qingshi to Qingyong Line 1334, it also increased the heat generated by the knife. Through artificial infrared retesting, it was discovered that the Qingyong 1334 line's sub-master knife A touched hair and heat was as high as 177 degrees Celsius, which was a critical defect and needed immediate treatment. Subsequently, the dispatcher of the power grid transferred the load, and the knife knife fever was controlled in a timely manner to avoid further intensification of abnormal events and ensured the security of the power grid.
