Abstract

The invention discloses a high-strength, high-hardness and weather-resistant porcelain insulator. The insulator is prepared from the following raw materials: kaolin, potassium feldspar, silicon dioxide, quartz stone, zirconium oxide and modified vanadium-cerium composite oxide powder. According to the invention, the raw material formula of the porcelain insulator is improved, and the obtained insulator has high compressive strength and high breakdown voltage value, and is not easy to break down and damage. The insulator is good in weather resistance and suitable for areas with severe temperature changes, and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of composite insulators, in particular to a high-strength, high-hardness weather-resistant porcelain insulator and a preparation method thereof. Background technique [0002] Insulators play an important role in high-voltage transmission lines. Firstly, they provide mechanical support for the wires that transmit current; secondly, they function as insulation to prevent grounding currents. Because high-voltage transmission lines have long transmission distances and large spans, a large number of insulators are required, and the normal operation of the entire power system is closely related to the working status of the insulators. During the operation of the insulator, there are not only the horizontal tension of the conductor and the vertical load of the conductor, but also the impact of climate change and the long-term corrosion of various chemical substances. Therefore, the insulator is also a component th...
