Reporters learned from the State Grid Shanxi Electric Power Company on January 11 that in 2023, Shanxi's external power transmission will reach 157.6 billion kilowatt hours, a year-on-year increase of 7.65%. Behind this huge power transmission volume, it is inseparable from a series of advanced power equipment. Support, such as isolation switches, vacuum circuit breakers, transformers, etc. These devices play a vital role in Shanxi's power grid, ensuring efficient and safe power transmission.
As the national power transmission base, Shanxi Power Grid's complexity and importance are self-evident. It is an important part of the North China UHV "Two Horizontal, Three Vertical and One Ring Network" and is responsible for transmitting power to Beijing, Hebei, Shanghai, Jiangsu, Hubei and other places. In order to ensure a stable supply of power, Shanxi Power Grid is equipped with a large number of switch cabinets and drop-out fuses. These devices play a key protective role in the power transmission process.
Among them, the Yanmenguan-Huai'an ±800 kV UHV DC transmission project is the main artery for Shanxi Electric Power to be sent to Jiangsu. Its stable operation is of great significance for ensuring the power supply in Jiangsu. Data shows that in 2023, the power transmission project delivered an astonishing 46.7 billion kilowatt hours, exceeding the record of 37.1 billion kilowatt hours in 2022, a year-on-year increase of 25.9%. This achievement is inseparable from the effective use of lightning arresters and other equipment, which play an important role in preventing power facilities from being affected by natural disasters such as lightning strikes.
In general, Shanxi Power Grid ensures the efficient and safe transmission of electricity by using a series of advanced power equipment and technical means such as isolating switches, vacuum circuit breakers, transformers, switch cabinets, drop-out fuses, and arresters, providing services to all parts of the country. Provides stable and reliable power supply.
