What are the connection modes and characteristics of the high-voltage distribution network in the factory?

As you said, there are single bus and double bus connections, but there are many others, such as single bus section, double bus section, single bus section with bypass bus, two-thirds circuit breaker connection and so on. These main electrical connections refer to the connection relationship between buses in the station.

The connection mode, radial, network format and ring of distribution network refer to the connection relationship between feeders. In the current distribution network, it is generally closed-loop design and open-loop operation, that is, radial operation is adopted in actual operation.
