Description

Technical Field

[0001] This utility model relates to the field of DC glass insulator technology, specifically DC glass insulators. Background Technology

[0002] DC glass insulators are insulating devices used in power systems. Made of glass, they support and insulate conductors. They are typically assembled by adhesive bonding or mechanical clamping of insulating components such as tempered glass and metal fittings such as steel feet and iron caps. As a crucial component in power systems, DC glass insulators offer advantages such as fatigue resistance, lightning protection, absence of breakdown and hidden defects, excellent insulation performance, and ease of maintenance and inspection. They play a vital role in insulation and support in high-voltage transmission lines, substations, and various high-voltage power equipment. When selecting DC glass insulators, it is recommended to prioritize products from well-known brands and manufacturers to ensure their quality and performance.

[0003] The prior art patent document CN207781296U discloses a DC glass insulator. This device has a zinc sleeve on the steel foot, which can act as a sacrificial electrode to protect the steel foot, thus reducing the severity of corrosion. Furthermore, a positioning ring is provided on the steel foot base, which can be used to roughly position the steel foot during manual gluing. A stepped groove is provided at the upper end of the steel foot base for further positioning of the steel foot during gluing. In addition, the three-umbrella skirt design can significantly improve the creepage distance and enhance the pollution resistance.

[0004] However, in the current technology, DC glass insulators are fixed only by bolts. This single fixing method may not be stable enough when facing complex and ever-changing external environments. The tightness of the bolts, the choice of materials, and factors such as wear and corrosion after long-term operation may all affect the stability of the insulator. Therefore, we need DC glass insulators. Utility Model Content

The column 402 and the mounting bolt 404 form a fixed structure, and the screw 403 is positioned between the column 402 and the mounting bolt 404, reinforcing the connection between the column 402 and the screw 404. The connection effect of section 3 allows the column 402 to be supported and fixed to the mounting bolt 404 by the screw 403. A nut 405 is provided on the outer wall of the mounting bolt 404. The screw 403 and the insulating disc 1 form a fixed structure through the mounting bolt 404, and one end of the mounting bolt 404 passes through the insulating disc 1 and connects to the nut 405, facilitating the setting of the nut 405. This allows the nut 405 to be tightened onto the outer wall of the mounting bolt 404, improving the installation and fixing effect of the insulating disc 1 and the steel foot 401. A fixing bracket is fixedly connected to the bottom of the insulating disc 1. 406. A threaded sleeve 407 is fixedly connected inside the fixing bracket 406. The fixing bracket 406 and the screw 403 form a threaded structure through the threaded sleeve 407. The inner diameter of the threaded sleeve 407 matches the outer diameter of the screw 403, and the inner wall of the threaded sleeve 407 fits snugly against the outer wall of the screw 403. This strengthens the connection between the fixing bracket 406 and the threaded sleeve 407, allowing the screw 403 to be securely installed within the threaded sleeve 407. This improves the installation stability of the fixing bracket 406 and the insulating disc 1. By connecting one end of the screw 403 to the insulating... The disc 1 is inserted, and the mounting bolt 404 can penetrate the threaded sleeve 407 and extend into the steel cap 2.
