Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to an AC disc-shaped suspension porcelain insulator. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, and are able to withstand voltage and mechanical stress. Insulators are of various types and shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings.

[0003] For example, the publication number CN211455402U discloses an AC disc-shaped suspended porcelain insulator, including a fixed block, a plug-in column fixedly installed at the bottom end of the fixed block, a plurality of umbrella-shaped ceramic sheets equidistantly inserted and connected on the surface of the plug-in column, a plurality of U-shaped grooves equidistantly opened on both sides of the plug-in column, a plurality of U-shaped blocks embedded inside the plurality of U-shaped grooves, a plurality of limit springs equidistantly fixedly installed on one side of the groove wall of the plurality of U-shaped grooves, one end of the plurality of limit springs fixedly connected to one side of the corresponding U-shaped block, one end of the two U-shaped blocks in opposite positions are engaged with the slots opened inside the umbrella-shaped ceramic sheet. The utility model is an AC disc-shaped suspended porcelain insulator, which is engaged with the red slots opened on both sides of the through hole in the middle of the umbrella-shaped ceramic sheet by the U-shaped blocks embedded inside the U-shaped grooves opened on both sides of the plug-in column, so as to facilitate the installation and removal of the umbrella-shaped ceramic sheet, and to facilitate the timely replacement of the umbrella-shaped ceramic sheet when the umbrella-shaped ceramic sheet is damaged.

[0004] However, the prior art cannot stably support the porcelain insulator body. In the prior art, the porcelain insulator body is moved by holding the porcelain insulator body, and the placement groove provided on the inner wall of the porcelain insulator body is clamped on the U-shaped block for fixing as the porcelain insulator body moves. However, the U-shaped block is fixedly connected to the spring, and only one end of the porcelain insulator body is fixed, so that the overall gravity of the porcelain insulator body is supported only by the end connected to the U-shaped block, and the spring fixed on one side of the U-shaped block is a compression spring. When the spring is accidentally hit, it will be compressed, which may easily cause the U-shaped block to move out of the groove in the porcelain insulator body, and the porcelain insulator body cannot be stably installed and used.
