Abstract: A high-voltage combined electrical apparatus includes a transformer, at least one circuit breaker, at least one oil/gas separation module and at least one operating mechanism. In an embodiment, the circuit breaker includes a ceramic insulator, an upper outgoing line seat, a lower outgoing line seat, and a disconnecting mechanism connected there between. The oil/gas separation module includes a first end electrically connected to a transformer coil of the transformer, and a second end electrically connected to the lower outgoing line seat. The operating mechanism is connected to and controls the disconnecting mechanism. The high-voltage combined electrical apparatus of an embodiment integrates a circuit breaker and a transformer, omitting the conventional transformer oil/gas sleeve and overhead line, so that the structure thereof is simpler, the cost is lower, the area of ground occupied by the equipment is reduced, and the occurrence of short circuits associated with overhead lines is avoided.
