UHV knowledge
What is the difficulty in UHV transmission technology?
The difficulty of UHV transmission technology lies in the high-voltage transmission of electricity and its adaptability to the environment. UHV cables need to withstand extremely high voltages, which requires the insulation materials, voltage-resistant equipment, control systems, etc. of the lines to have extremely high reliability and safety. At the same time, during the process of long-distance power transmission, we have to face the challenges of various meteorological conditions, such as lightning strikes, sandstorms, ice and snow, high temperatures, etc., which requires the material and structural design of the lines to be stronger and more stable.
The main reasons why China can play with UHV transmission technology are:
Policy support:
The Chinese government has always attached great importance to the development of the energy field, especially the research and application of power transmission technology. The government has repeatedly issued relevant policies and funding to provide support and guarantee for the research of UHV power transmission technology.
Superior resource conditions:
The construction of China's UHV transmission lines requires large-scale investment and resources, including land, materials, equipment, etc. China is rich in natural resources such as coal and hydropower, and has good production capacity and technical level in the fields of manufacturing and engineering construction, which facilitates the promotion and application of UHV transmission technology.
Technological innovation:
China has carried out a lot of technological innovation and research and development in UHV transmission technology, such as using power electronic devices to realize loss-free regulation of transmission lines, using gas-insulated central tube design to improve the durability of lines, etc. These technologies The application of UHV transmission lines has greatly improved the efficiency and reliability of UHV transmission lines.
Experience accumulation:
China has accumulated rich experience in multiple UHV transmission projects, such as DC transmission, overhead transmission, underground transmission and other methods, which makes China more comfortable in the application and promotion of UHV transmission technology.
