Description

Technical field [0001] The invention relates to the technical field of high-voltage transmission line detection, in particular to an unmanned aerial vehicle-based transmission line zero-value insulator live detection device and method. Background technique [0002] Insulators are a large number of parts and components in the power grid. They must not only insulate electrical equipment or conductors, but also play a fixed suspension role. Under the long-term effects of factors such as sunshine, mechanical stress, changing temperature and humidity, strong electric field, and pollution, when the deterioration reaches a certain level, the insulation performance of the insulator will be reduced, directly affecting the safe operation of the power system. If there are zero-value insulators in the insulator string, it is equivalent to part of the insulation being short-circuited, and the overall creepage distance of the insulator string is reduced accordingly, thus greatly increasing the...

AI Technical Summary

Problems solved by technology

[0004] (1) The detection of zero-value insulators by the spark gap needle requires a pole-mounted operation, and the work is labor-intensive;

[0005] (2) The pulse current method is detected by measuring the leakage current of the insulator string, which is easily affected by high-frequency interference;

[0006] (3) The infrared imaging method is realized by detecting the local temperature rise of the insulator caused by partial discharge, leakage current, etc. The instrument is complicated and the measurement accuracy is not high;

[0007] (4) The zero-value insulator live detection robot detects the insulator voltage through the robot crawling on the insulator, which still needs to manually place the robot on the insulator, and the labor intensity is still relatively high

[0008] To sum up, the current zero-value insulator detection method has the problems of high labor intensity and low accuracy.
