Description

technical field [0001] The invention relates to a mobile detection robot, in particular to an insulator detection robot. Background technique [0002] Insulators are insulation equipment used to connect conductors and iron towers on overhead high-voltage transmission lines. The preventive detection of degraded insulators is of great significance to ensure the safe operation of high-voltage transmission lines. The traditional detection method is to manually climb towers and work at heights. However, with the increase of the voltage level, the length of the insulator string continues to increase, and the difficulty of manual inspection is also increasing. Therefore, the development of an insulator live detection robot that can automatically walk along the insulator string has become an effective way to solve the insulator live detection of ultra-high voltage transmission lines. There are two main ways to use insulator strings in EHV transmission lines: horizontal and hanging,...

AI Technical Summary

Problems solved by technology

There are two main ways to use insulator strings in EHV transmission lines: horizontal and hanging, and it is more difficult to realize the automatic walking device for detection of horizontal insulator strings.

[0003] Existing insulator detection devices do not fully consider some practical problems, and there are many deficiencies. For example, because the insulator porcelain skirt is usually coated with anti-pollution flashover paint, the existing insulator detection walking device will cause the insulator porcelain to Abrasion of the anti-fouling flashover paint on the skirt; the distance and potential difference between the insulator string and the iron tower are large, and the operation of the string is difficult; the conductor along the string direction is likely to cause direct or inductive short-circuiting of the insulator, which reduces the safety of live work; The distances between insulators are actually not equal, the continuity along the series is poor, and the inspection speed is slow

In a word, there is no effective and practical insulator live detection robot in this technical field so far
