Description

Technical Field

[0001] The invention relates to the technical field of porcelain insulators, in particular to a porcelain insulator which is convenient to assemble. Background Art

[0002] Insulators are electrical components used in power systems. They are mainly used to isolate high-voltage wires from brackets and the ground to prevent current leakage and electric shock accidents. Usually, insulators are made of insulating materials and can maintain sufficient insulation performance even in extreme environments. Insulators need to be disassembled and inspected after long-term use to avoid the connection between each insulator from breaking and causing loss of support for the wire. When inspecting the insulator, the insulator group on the pole or tower needs to be removed, and then the new insulator group is connected to the wire, and the insulator is connected to the pole or tower.

[0003] For example, a Chinese patent application with publication number "CN116682626A" discloses "a hollow porcelain insulator umbrella structure", whose main structure includes an umbrella structure, a connecting column, a supporting base, a connecting plate, a movable component and a protective component. The hollow porcelain insulator umbrella structure and its porcelain insulator can utilize a protective component to protect its umbrella structure when it is squeezed. While protecting, it can greatly improve the protective strength of the umbrella structure, increase the practicality and sustainability of the umbrella structure, and reduce the economic cost of maintaining and replacing the umbrella structure.

[0004] However, when installing or replacing the above-mentioned hollow porcelain insulator umbrella structure, the porcelain insulator body needs to be disassembled or installed in the power tower. During installation, since the angle between the pin mouth and the porcelain insulator body is fixed, the entire porcelain insulator body needs to be rotated during installation so that the pin mouth can be turned to a suitable angle for pin shaft installation, which makes the installation process more complicated.
