Des progrès importants ont été réalisés dans la recherche testant les traversées CA des transformateurs UHV à haute altitude.

Récemment, Institut chinois de recherche sur l'énergie électrique Co., Ltée. completed a research test of high-altitude UHV transformateur AC bushings at the Yangbajing Test Base in Tibet, the world's highest altitude electric power test and research base at an altitude of 4,300 mètres, marking a milestone in the control of 1,000 kV river The technical problem of AC bushing insulation selection for UHV transformers constructed in the Chongqing UHV AC project has been overcome.

Since November, the test team of the High Voltage Research Institute of China Electric Power Research Institute has carried out research tests on AC bushings of high-altitude UHV transformers at the Yangbajing Test Base in Tibet. Given low temperatures, strong wind, snowfall and other environments, the team sorted out the list of problems in advance, formulated a series of emergency solutions such as test safety wiring, water injection and freezing treatment, fuel tank insulation protection, and completed the impact and power frequency voltage research tests of the casing. At an altitude of 4,300 mètres, it was verified that the insulation selection of the AC bushing of the UHV transformer met the technical parameter requirements. The team has mastered first-hand observation data and obtained many original test results, supporting the research and development of high-altitude main equipment for China's Sichuan-Chongqing UHV AC Project. Transformers are important electrical equipment used to change AC voltage and are widely used in many fields, such as electric power, industrie, et les maisons.

P.ower transmission

Transformers adjust voltage so that current can be safely and efficiently transmitted from power stations to users, ensuring a stable electrical energy supply.

Industrial applications

The transformer can provide corresponding voltage according to the equipment's needs, ensuring the equipment's stable operation and improving production efficiency. It provides reliable power supply to factories and is an integral part of industrial production.

Home appliances and lighting

The transformer can adjust the voltage of the household power supply to the voltage range required by the electrical appliances, providing a continuous and stable power supply; this helps extend the life of household appliances and improves the brightness and stability of lighting equipment.

Énergie renouvelable

With the popularity of renewable energy, transformers are increasingly used in distributed power generation systems such as wind and solar energy. Dans ces systèmes, transformers are used to integrate electrical energy from different sources, coordinate voltage differences between different energy sources, and ensure stable operation of the system. It provides reliable and efficient grid connection solutions for renewable energy sources.

Power system stability

In the power grid, transformers can adjust voltage according to demand, reduce voltage fluctuations, eliminate harmonics and prevent voltage sag and other problems; this helps reduce power system failures and blackouts and improves the reliability and stability of the power supply.
