Description

Technical Field

[0001] The utility model relates to the technical field of unloading devices, in particular to auxiliary equipment for replacing insulators of high-voltage lines. Background Art

[0002] The primary purpose of replacing insulators on high-voltage lines is to improve power supply reliability and ensure safe line operation. Insulators play a crucial role in high-voltage lines. Positioned between conductors and towers, they provide electrical insulation and mechanical support, ensuring safe and stable current transmission. However, over time, insulator performance may degrade due to contamination and aging, potentially posing safety risks. Therefore, regular insulator replacement is a key measure to maintain stable power system operation.

[0003] According to Chinese patent CN 105226562 B, a post insulator auxiliary replacement device and mounting structure are disclosed. When maintenance personnel replace or repair a faulty post insulator in a substation, they hang the hanging portion of the post insulator auxiliary replacement device on an angle steel plate, connect the limiting portion to an aluminum bar, and place the post insulator above the supporting portion. This allows the supporting portion to support the post insulator during replacement or repair, eliminating the need for manual gripping. This reduces workload and shortens replacement time.

[0004] In the aforementioned patent, a support plate is used to support the post insulator during replacement or removal, improving operator convenience. However, the support plate does not secure the post insulator. During movement of the device, the post insulator being removed or replaced above the support plate can easily slide off, reducing safety. To address this issue, we have provided an auxiliary device for replacing high-voltage line insulators. Utility Model Content
