Description

Technical Field

[0001] The utility model relates to the technical field of insulators, and particularly relates to a steel foot of a suspension porcelain insulator. Background Art

[0002] As an important component in the power system, suspension porcelain insulators are widely used in high-voltage transmission lines, and their performance is directly related to the safe and stable operation of the power system. As one of the key components of the suspension porcelain insulator, the steel foot not only bears the weight and tension of the conductor, but also withstands the influence of various harsh weather conditions and environmental factors. Therefore, the strength and stability of the steel foot are crucial for the overall performance of the insulator.

[0003] In the traditional design of the steel foot of the suspension porcelain insulator, only its basic load-bearing function is often considered, while the problems of insufficient strength and reduced stability that may occur under extreme working conditions are ignored. Under harsh weather conditions such as strong wind and icing, the conductor will be subjected to large wind pressure and ice load, resulting in the steel foot of the insulator bearing huge tension and bending moment. If the strength and rigidity of the steel foot are insufficient, it is easy to break or deform, thus affecting the service life of the insulator and the safety of the power system. Therefore, we propose a steel foot of a suspension porcelain insulator. Summary of the Utility Model
