Circuit breaker with inter-electrode connection structure

The invention discloses a circuit breaker with an inter-electrode connection structure. The circuit breaker comprises a main body part and an inter-electrode connecting part, wherein the main body part comprises a circuit breaker body with at least three phases of mutually isolated spaces; each phase internally comprises a conductor with a static contact and a moving contact, the inter-electrode connecting part comprises a connecting bar, the connecting bar is arranged outside the main body part, one end of the connecting bar is connected with the conductor of one phase, and the other end of the connecting bar is connected with the conductors of the other phases; an insulating part completely isolates the inter-electrode connecting part from the circuit breaker body such that the influenceof the inter-electrode connecting part on the circuit breaker body is eliminated, and the insulation level is greatly improved; after the inter-electrode connecting part is isolated, the heat generated by the inter-electrode
