Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage leakage, and particularly to a hoisting type high-voltage leakage current inspection device. Background Art

[0002] In the operation and maintenance of high-voltage transmission lines, ensuring the safe and stable operation of the power system is of crucial importance. Among them, the performance status of high-voltage cable insulators directly affects the reliability of the transmission line.

[0003] Insulators are exposed to the natural environment for a long time and are affected by various factors. For example, dust, pollutants, etc. in the air are easily attached to the surface of the insulators, and over time, the dust accumulates continuously. This accumulated dust may absorb moisture in the air, forming a conductive channel, thus greatly increasing the risk of electric leakage. Once electric leakage occurs, it will not only cause power loss, but may also trigger a series of safety problems, such as surface flashover and arc discharge of the insulators, which may further lead to transmission line failures, affect the continuity of power supply, bring inconvenience to production and life, and even endanger the safety of surrounding personnel and equipment.

[0004] Traditional inspection methods mostly rely on manual operation. Manual inspection faces many difficulties. On the one hand, high-voltage transmission lines are often distributed in relatively complex geographical environments, such as mountainous areas, forest lands, etc. It may take a lot of time and effort for the staff to reach the inspection location, and in some special terrains, there are certain dangers in carrying out the inspection work. On the other hand, the accuracy and efficiency of manual detection are relatively low. It is difficult for the staff to comprehensively and carefully clean the floating dust on the surface of the insulators, which makes it difficult to obtain accurate detection results due to the interference of the surface floating dust when detecting the high-voltage leakage current. Moreover, the manual detection speed is slow, and it is impossible to quickly detect a large number of insulators, making it difficult to meet the needs of large-scale high-voltage transmission line inspections.

[0005] In addition, with the continuous development of the power system, the scale of high-voltage transmission lines is increasing day by day, putting forward higher requirements for the efficiency, accuracy and safety of inspection work. Traditional inspection methods have gradually become difficult to meet the needs of modern power system operation and maintenance. Therefore, it is of great practical significance to develop a hoisting type high-voltage leakage current inspection device for its problems, which also promotes the emergence of this hoisting type high-voltage leakage current inspection device to solve the above problems existing in the prior art.

The surface dust of the insulator and the connecting column of the insulator is cleaned by two sets of cleaning brushes. Firstly, it effectively avoids the leakage risk caused by long-term dust accumulation.
