Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage detection equipment, and in particular to a safety detection device for insulators of high-voltage transmission lines. Background Art

[0002] Line insulators are industrial products used for insulation and suspension of conductors in high-voltage and ultra-high-voltage AC and DC transmission lines. The resistance value of high-voltage transmission line insulators directly affects the safe operation of the transmission line. Once a problem occurs in the insulator, it must be replaced immediately, otherwise it will affect the operation of the high-voltage transmission line, and in serious cases, it will cause significant losses to the operation of the national economy and people's lives and property.

[0003] Currently, the main method used is manual inspection of each piece on the tower. However, since the insulators of high-voltage transmission lines are usually located diagonally above the tower on both sides and there is a certain distance between them and the tower, and during the inspection, the line insulators may swing due to external factors such as wind, which adds a certain degree of difficulty to the inspection process.

[0004] In addition, during the long-term operation of the transmission line, a layer of impurities will be attached to its surface, which will cause certain damage to the insulation performance of the insulator. Therefore, in order to ensure the insulation performance of the insulator, cleaning work can be carried out to remove the impurities on the surface of the insulator. When cleaning, you can use the corresponding dry eraser, and use tools such as plastic balls and gloves to clean the insulator to effectively remove the impurities on the surface of the insulator. And while cleaning, you must also carefully check the insulator to see if there are cracks, damage and other defects on its surface. If problems are found, they must be replaced in time.

[0005] Therefore, in daily inspection and maintenance, insulators need to be cleaned regularly. However, since it is an aerial operation and the insulators lack fixed support devices, the insulators will swing and shake during the cleaning process, which will bring certain difficulties to the cleaning.
