Experimental study on arc discharge of detection robot in UHV line

Abstract

Manual detection of insulators on UHV lines is a significant security risk. Therefore, it is practical and valuable to develop an insulator inspection robot. At present, there are few reports on the application of robots in the detection of UHV lines. Based on the live detection test of 1000kV transmission line insulators, the communication system test, the detection system test, the image transmission system test, and the appearance arc test were conducted in the high-voltage laboratory. The paper studied the insulation level test of the robot and explored the influence of probe length and position on arc discharge. A safe area for live robot operation was obtained.
