Description

Technical Field

[0001] This utility model relates to the field of power distribution line technology, and in particular to a self-cleaning composite insulator device for power distribution lines. Background Technology

[0002] Composite insulators are mainly used for electrical insulation of high-voltage transmission lines and substations. Composite insulators consist of silicone rubber skirts, glass fiber reinforced epoxy resin core rods, and galvanized carbon steel end fittings.

[0003] However, the following drawbacks still exist: traditional bare conductors and porcelain insulators face wind and sand erosion, rainwater pollution accumulation caused by humid environments, and icing problems caused by freezing weather during long-term operation. These problems not only increase the difficulty of maintenance work, but may also lead to line faults and seriously affect power supply. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

The diameters of two adjacent sheds are different. An insulating plate is fixedly connected to the top of the resin rod, and inclined plates are welded to multiple sides of the insulating plate.

[0006] As a further embodiment of this invention, a mounting block is fixedly connected to the bottom end of the resin rod.

[0007] As a further embodiment of this invention, a connecting block is fixedly connected to the top end of the resin rod.

[0010] As a further embodiment of this invention, a first sealing ring is fixedly connected at the connection between the insulating plate and the top of the resin rod.

[0011] As a further improvement of this utility model, the top of each of the umbrella skirts is provided with an inclined arc surface.

[0012] As a further improvement of this utility model, the umbrella skirt is shaped like an umbrella cap.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model, by opening an inclined arc surface at the top of the umbrella skirt, can guide impurities at the top of the umbrella skirt, achieve self-cleaning and anti-fouling, help maintain the cleanliness of the insulator, and reduce the problem of decreased insulation performance caused by the accumulation of impurities.

[0014] 2. This utility model has a first sealing ring at the connection between the top of the resin rod and the insulating plate, which can improve the sealing between the two and prevent the intrusion of external substances such as moisture. A second sealing ring is provided at the connection between the bottom of the resin rod and the mounting block to improve the sealing at the connection.

[0015] 3. The rubber insulating plate and inclined plate used in this utility model can enhance the overall insulation effect of the device. When the staff disassembles or assembles the device, they can use the insulating plate to position it and also to provide auxiliary shielding for the multiple umbrella skirts at the bottom of the insulating plate.
