Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a composite column insulator with a long steel leg structure. Background Art

[0002] Insulators are electrical isolation devices used to ensure the good performance of power equipment. Composite post insulators usually consist of three parts: glass fiber epoxy resin pull-out rods, silicone rubber sheds, and hardware. The main function of lengthening the steel legs of the insulators is to enhance the mechanical strength and stability of the insulators, and to adapt to different installation and use environments.

[0003] In the design and application of insulators, the steel foot is an important component. The steel foot not only connects and supports the insulator, but can also be extended to better adapt to different installation and use environments. The extended design of the steel foot can adapt to different voltage levels and installation height requirements, ensuring that the insulator can effectively isolate power equipment and prevent current from returning to the ground, thereby protecting the safety of equipment and personnel.

[0004] However, the extended steel foot needs to be positioned more stably during installation to avoid unstable installation during long-term use. For example, Chinese utility model patent CN213042733U provides a stably installable steel foot for a porcelain insulator, comprising a porcelain insulator, a steel foot mounted on the lower end of the insulator, the steel foot being provided with an annular groove, the annular groove being sleeved with an annular plate, the annular plate being provided with an upper mounting groove, the upper support rod being mounted in the upper mounting groove, the steel foot being sleeved with a circular column, the circular column being provided with a lower mounting groove, the lower support rod being mounted in the lower mounting groove. This technical solution forms a diamond-shaped support frame through four upper support rods and four lower support rods, which can support the stability of the porcelain insulator and avoid the situation where the porcelain insulator is bent and deformed and affects its use. By controlling the hook to disengage or insert into the plug-in slot and controlling the circular column to disengage or mount on the steel foot, the porcelain insulator can be disassembled or installed. The operation is simple, and the efficiency of disassembly and installation of the porcelain insulator is improved.

[0005] However, the structure of the device for fixing the steel legs is relatively complex and inconvenient to adjust and install. The applicant has designed a composite post insulator with a long steel leg structure, which is easy to install and adjust and has good stability. Utility Model Content
