Description

Technical Field

[0002] UHV has the characteristics of large transmission capacity, long transmission distance, low line loss and less land occupation. It has significant advantages in improving the large-scale allocation and supply of energy resources, promoting energy structure adjustment and clean and low-carbon development, and is known as the "power highway". In recent years, the development of UHV has made comprehensive breakthroughs from basic research to engineering practice, and has entered the "Belt and Road" national initiative, realizing "Made in China" and "China Leading". my country's UHV and high-speed rail technologies are at the international leading level and are emerging industries with internationalization that my country will focus on supporting and developing in the future.

[0003] However, according to statistics from relevant departments in my country, the number of power outages caused by "pollution flashover" is second only to the number of power outages caused by lightning strikes, and is on a rapid upward trend. "Pollution flashover" brings huge losses to the national economy and seriously affects public safety and people's normal lives. Therefore, solving the "pollution flashover" problem has important social significance.

[0004] Insulation technology is the key technology of UHV. Insulators are the core components and external insulation materials of UHV insulation technology, and they mainly play a supporting and insulating role. The ultra-large-size pillar porcelain insulator products for UHV are not only complex in structure, but also large in size. The maximum porcelain height reaches 2300mm and the maximum product weight reaches 700kg. It is difficult to use the traditional coating and hardening method, and the coating and hardening must be completed before cutting and gluing. The coating is seriously damaged and contaminated during this process, which is not conducive to the protection of the coating and the performance of the later effect. Summary of the invention
