【Abstract】 Aiming at the problems of low efficiency, high cost, high manual labor intensity and personnel safety of traditional power checking methods, this paper designed a UAV airborne multi-voltage non-contact power checking device, which can realize the power checking of all phases of 35,110,220 and 500 kV double-back transmission lines.On the basis of analyzing the checking principle of non-contact checking sensor, the hovering height of the UAV,the horizontal distance and the installation position of the sensor through simulation were obtained, and at the same time, in order to solve the problems of power checking blind area and power outage false alarms, the power checking thresholds for lines of different voltage grades were simulated.The power checking device can realize the functions of threshold switching, wireless transmission of power checking information and power test alarm, and so on.Through the four voltage levels of line field test, the results show that when the line is energized and out of power, there is a significant difference in the measured value of the corresponding power checking position.The power test time for a three-phase outage line is about 1 minute and 40 seconds, and the power checking device can realize fast and accurate power checking.更多还原
