1.Definition and Function1.1 Role of the Generator Circuit BreakerThe Generator Circuit Breaker (GCB) is a controllable disconnect point located between the generator and the step-up transformer, serving as an interface between the generator and the power grid. Its primary functions include isolating generator-side faults and enabling operational control during generator synchronization and grid connection. The operating principle of a GCB is not significantly different from that of a standard c

1. Introduction Transmission line faults can be classified into two types based on their nature: transient faults and permanent faults. Statistical data shows that most transmission line faults are transient (caused by lightning strikes, bird-related incidents, etc.), accounting for approximately 90% of all faults. Therefore, after a line is disconnected due to a fault, attempting reclosure once can significantly improve power supply reliability. The function of automatically reclosing a circuit

A "2-in 4-out 10 kVsolid-insulated ring main unit" refers to a specific type of ring main unit (RMU). The term "2-in 4-out" indicates that this RMU has two incoming feeders and four outgoing feeders.10 kVsolid-insulated ring main unit are equipment used in medium-voltage power distribution systems, primarily installed in substations, distribution stations, and transformer stations to distribute high-voltage power to low-voltage distribution networks. They generally consist of high-voltage incomi
