Unmanned aerial vehicle electricity testing method and device for power transmission line

Abstract

The invention provides an unmanned aerial vehicle electricity testing method for a power transmission line. The method comprises steps of remotely controlling an unmanned aerial vehicle to take off after the preparation work before electricity testing is completed, enabling the unmanned aerial vehicle to vertically rise to a preset height, and keeping a hovering state, and enabling the preset height to be set based on a voltage level of a to-be-tested power transmission line; performing head positioning operation of the unmanned aerial vehicle, in the head positioning process, the head of theunmanned aerial vehicle swinging left and right, and measuring a linear distance between the head and the to-be-measured power transmission line in the period so as to obtain the head direction of theunmanned aerial vehicle; setting waypoints at fixed intervals based on the voltage class of a to-be-measured power transmission line, the minimum flight safety distance and the linear distance between the to-be-measured power transmission line and the to-be-measured power transmission line in combination with the nose direction, and generating a route; remotely controlling the unmanned aerial vehicle to enter an air route mode, hovering point by point according to waypoints in the air route, completing electricity testing operation of the to-be-tested power transmission line, and obtaining electricity testing data. The method is advantaged in that the method is suitable for to-be-tested power transmission lines of various voltage levels, and is suitable for electricity testing sites of different terrain environments.

Description

technical field [0001] The invention relates to the technical field of power inspection of power transmission lines, in particular, to a method and device for power inspection of power transmission lines using an unmanned aerial vehicle. Background technique [0002] Operation and maintenance work is an important means to grasp the operation status of power grid equipment, discover and deal with equipment defects in time. The "State Grid Corporation Electric Power Safety Work Regulations (Power Line Part)" clearly stipulates that: before installing the ground wire in the working section of the power outage line, the electricity should be checked first to verify that the line has no voltage. For electrical inspection, a qualified contact electroscope with corresponding voltage level should be used. For equipment that cannot be directly tested, high-voltage direct current transmission equipment, and outdoor equipment in rainy and snowy weather, indirect electrical testing can...

Problems solved by technology

The lengths of insulating rods used for contact electroscopes of various voltage levels are: 3m for 220kV, 5m for 330kV, and 7.2m for 500kV. The insulator string is long and the operating parameters are high. In addition, the phase-to-ground distance is large, and the insulation operating rod is required to have a long length. On the one hand, the weight of the operating rod is large, which will greatly increase the labor intensity of the operator; on the other hand. The long insulating operating rod is easy to bend and not easy to operate
