In order to meet the needs of smart grids, research work on high-voltage vacuum circuit breakers and high-voltage chain STATCOM control technology and equipment based on intelligent modules has been completed. The development of series high-voltage vacuum circuit breaker prototypes and high-voltage chain STATCOM controller prototypes has been completed, such as As shown in Figure 2.3 and Figure 2.4.

At the same time, application research on high-voltage pulse discharge technology was carried out, and a high-voltage pulse discharge prototype and application system were developed, as shown in Figure 2.5.
