AI Technical Summary

Problems solved by technology

For a single switch interval, if a combination unit and a smart unit with separate functions are used, the number of equipment in the station is large, and installation and debugging are inconvenient. Substation construction and subsequent maintenance and maintenance costs are high, and safety and reliability are relatively low.
