Description

technical field [0001] The present application relates to the technical field of fault detection of overhead transmission line system devices, and in particular to a UAV-based degraded insulator detection system and method. Background technique [0002] Insulators are important components for mechanical support and electrical connection in transmission lines. Once the main body deteriorates, it may cause serious failures such as broken strings and insulation failures. There is a space electric field distributed around the live running insulator. When deterioration occurs, the space electric field around it will be locally distorted relative to the normal state. Therefore, the operating state of the insulator can be diagnosed by comparing and analyzing the electric field distribution characteristics before and after deterioration. Therefore, it is of great significance to regularly carry out space electric field electrification detection on the running insulators of transmiss...

AI Technical Summary

Problems solved by technology

[0003] The existing detection methods for degraded insulators on overhead transmission lines are divided into traditional contact detection methods and emerging non-contact detection methods. Traditional detection methods include observation method, spark fork method, etc., which require manual tower climbing, which is cumbersome and dangerous to operate. Among the non-contact detection methods, the infrared temperature measurement method and the ultraviolet imaging method are easily affected by the external environment, which has a greater impact on the detection sensitivity, while the electric field distribution detection method is limited by the environment and has a higher sensitivity. The method has broad application prospects
