Combined structure of circuit breaker and isolating switch and switch cabinet

The invention relates to the technical field of electrical equipment, and particularly discloses a combined structure of a circuit breaker and an isolating switch and a switch cabinet. The combined structure of the circuit breaker and the isolating switch comprises the circuit breaker, the isolating switch and a driving assembly. The circuit breaker comprises three phases of solid-sealed polar poles, and each phase of solid-sealed polar pole comprises a circuit breaking static contact and a circuit breaking moving contact. The isolating switch comprises isolating static contacts and isolating moving contacts which are in one-to-one correspondence, at least one isolating moving contact is arranged on each phase of solid-sealed polar pole, the isolating moving contacts are electrically connected with the circuit breaking moving contacts or the circuit breaking static contacts, and the isolating static contacts are arranged on the inner wall of the switch cabinet; the driving assembly comprises a transmission pa
