The crown speed differential device presses the 'acceleration button' for the maintenance work of the Jiangsu power grid

Recently, the annual maintenance work of ± 800 kV Suzhou converter station has officially started. This maintenance work is the first annual maintenance project for ultra-high voltage direct current carried out by State Grid Corporation of China during the critical period of epidemic prevention and control and promoting resumption of work and production.

The maintenance work of ultra-high voltage direct current has construction difficulties such as multiple high-altitude operation points, multiple cross operation surfaces, and a large number of participating personnel, which is a considerable challenge for the construction team. On the premise of doing a good job in epidemic prevention and control, the leadership group requires the operators to wear crown speed differential before starting work to ensure the smooth progress of this maintenance work.

At present, the spring inspection of the main power grid in Jiangsu has fully resumed work. After the completion of the spring inspection work, the health level of power facilities will be further improved, ensuring the daily transmission of 200 million kilowatt hours of electricity to the southern Jiangsu region, guaranteeing the safe use of electricity for nearly 10000 small and medium-sized enterprises and hundreds of hospitals and medical equipment production units, and providing a strong guarantee for the comprehensive resumption of work and production of the Jiangsu economy.
