Description

Technical Field

[0001] This utility model relates to the field of porcelain insulator technology, specifically a multi-umbrella type porcelain insulator. Background Technology

[0002] Porcelain insulators were originally used primarily on utility poles, but later gradually applied to high-voltage power line connection towers. At one end of a high-voltage power line connection tower, numerous disc-shaped insulators are typically hung; these insulators are usually made of glass or ceramic and their function is to increase the creepage distance.

[0003] Porcelain insulators, as an important power transmission device, typically employ an integrated design for their conductors and bases. Since porcelain insulators are primarily used in outdoor environments, they are inevitably exposed to natural conditions, including wind, sun, rain, and chemical corrosion. This harsh working environment makes the base prone to corrosion and rust. When the base rusts to a certain extent, its mechanical and electrical properties significantly deteriorate, failing to meet normal operating requirements, necessitating replacement. However, in traditional porcelain insulator designs, the base is tightly connected to the entire device; replacing the base requires disassembling the entire device. This process is not only time-consuming and labor-intensive but also increases safety risks due to frequent disassembly and reassembly, especially in high-altitude or complex environments, potentially leading to accidents and threatening the stability and safety of the power system. Summary of the Invention

[0028] Working principle: The operator first places the rectangular guide post 1 into the rectangular groove 16 on the base 10. Then, the operator rotates the knob 13 to move the moving block 17. Before the two side blocks 21 enter the fixing holes 3, the operator rotates the two side blocks 21 to the corresponding shape in the fixing holes 3.
