Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission lines, in particular to a composite insulator component with a positioning structure. Background Art

[0002] High-voltage transmission lines are divided into cable transmission lines and overhead transmission lines. The electricity generated by the power plant cannot be directly transmitted through ordinary wires, but needs to be transmitted through high-voltage transmission lines. Generally, the transmission voltage below 220kv is called high-voltage transmission, the transmission voltage between 330 and 765kv is called ultra-high-voltage transmission, and the transmission voltage above 1000kv is called ultra-high-voltage transmission. When the electricity is transmitted to the place where it is used, the voltage must be lowered before it can be used.

[0003] Insulators are important components in high-voltage transmission line technology. Currently, most insulators are made of glass or ceramics and are generally placed at high altitudes to support the conductors of transmission lines and prevent current from returning to the ground. Traditional composite insulators have an overly complex installation and fixing structure, which requires workers to spend a long time installing and fixing them at high altitudes, affecting their work efficiency.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The installation and fixing structure of the existing composite insulator is too complicated, and the workers need a long time to install and fix it at high altitude, which affects the work efficiency of the workers; 2. The existing composite insulators are damaged due to long-term wind and sun exposure, and the traditional installation structure is relatively simple, which makes it difficult to replace and repair the insulator in a timely manner.

To achieve the above purpose, the present utility model provides the following technical solutions: a composite insulator assembly with a positioning structure includes an insulating core column, an insulating umbrella sleeve is installed on the outer side of the insulating core column, a rotating block is installed through both ends of the insulating core column, a male block is installed on the surface of the rotating block, a sliding groove is opened on the inner wall of the male block, a latch is installed through the outer side of the male block, a female block is installed on the inner wall of the male block, a slider is installed on the outer side of the female block, and a mounting plate is installed on the surface of the female block.

[0006] Further preferably, a plurality of insulating umbrella covers are provided, and the insulating umbrella covers are equidistantly distributed, and the central axis of the insulating umbrella cover coincides with the central axis of the insulating core column.

[0007] Further preferably, a rotating structure is formed between the male block and the rotating block.

[0008] Further preferably, the male block forms a plug-in structure with the sliding block and the female block through a sliding groove.

[0010] Further preferably, the shape of the slide groove is set to be L-shaped, and the slide groove is attached to the inner wall of the male block.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, a positioning structure is adopted, and the user can quickly connect the male block with the female block through the slider on the outer side of the female block and the slide groove on the inner wall of the male block, move the slide groove of the male block along the slider of the female block, and then rotate the male block through the rotating block until the circular holes of the male block are consistent with those of the female block, and fix them through the latch, so the installation process is relatively convenient.

[0013] The utility model adopts a design that is easy to disassemble. By pulling out the pin and then rotating the male block 90 degrees counterclockwise through the rotating block, the male block can be directly pulled out to complete the separation between the male block and the female block, which is convenient for replacing or repairing the insulator, so that the component has the function of being easy to repair and replace.
