Unmanned aerial vehicle zero detection device for strain tower porcelain insulator of ultra-high voltage power transmission line

Abstract

An unmanned aerial vehicle zero detection device for a strain tower porcelain insulator of an ultra-high voltage power transmission line is characterized in that an insulator detector is carried by an unmanned aerial vehicle to collect the distribution condition of an electric field around the strain porcelain insulator, whether a degraded insulator or a zero-value insulator exists in an insulator string is compared, analyzed and judged according to the detected data, and the detection operation of the insulator is completed instead of manual work. Through the real-time monitoring of the pan-tilt camera and the flexible adjustment of the mechanical arm assembly, the detection needle can accurately enter the space between the insulators to be detected, so that the labor intensity of workers is reduced, the operation difficulty is reduced, the efficiency and quality of detection operation are greatly improved, and the influence on the personal safety of operators is avoided. The upper part of the unmanned aerial vehicle is also provided with a rotor wing protection device, and the arrangement of the rotor wing protection device can ensure that the unmanned aerial vehicle can avoid the influence of a power transmission line on a rotor wing in the rising process, so that the detection needle is smoothly moved to the position of an insulator chain needing to be detected, and the subsequent zero detection operation of the insulator chain is facilitated.

technical field [0001] The invention relates to the technical field of transmission line maintenance devices, in particular to an unmanned aerial vehicle zero detection device for ultra-high voltage transmission line tension tower porcelain insulators. Background technique [0002] Porcelain insulators are often used in the tension towers of overhead transmission lines. During long-term operation, a single piece of porcelain insulator may deteriorate, or even become a zero-value insulator, which seriously affects the insulation performance of the entire string of insulators and threatens the safe operation of the line. At present, the zero-value insulator detection instrument is mainly a contact zero detector, which is installed at the front end of the insulating rod.

[0002] Porcelain insulators are mostly used in the tension towers of overhead transmission lines. During long-term operation, a single piece of porcelain insulator may deteriorate, or even become a zero-value insulator, which seriously affects the insulation performance of the entire string of insulators and threatens the safe operation of the line.

At present, the zero-value insulator detection instrument is mainly a contact zero detector, which is installed at the front end of the insulating rod. The operator holds the rear of the insulating rod on the tower, and controls the steel needle of the zero detector to touch the steel caps on both sides of the single-piece insulator at the same time. Judging whether the insulator has deteriorated by the measured voltage, but the above-mentioned traditional method has the disadvantages of high labor intensity and difficult operation, and there is also a certain risk in the personal safety of the maintenance personnel during the operation, which seriously affects the zero inspection of the overall porcelain insulator. operational efficiency
