Embodiment Construction
[0023] like Figure 2 to Figure 3 As shown, an embodiment of a circuit breaker, the circuit breaker in this embodiment includes a fixed frame (not shown in the figure), the fixed frame is provided with a double-break circuit breaker with two break units symmetrically arranged, and the two breaks The units are symmetrically arranged at left and right intervals, and each fracture unit has two parallel fractures, the two fractures are the main fracture M and the resistance fracture N arranged at intervals along the up and down direction, where the main fracture M is the first fracture, and the resistance fracture N Then it is the second fracture, wherein the first fracture includes the active contact rod 10 , and the second fracture includes the resistive movable contact rod 6 arranged in parallel with the active contact rod 10 .
[0024] In this embodiment, the two fracture units are driven by the operating mechanism through the fracture transmission device to perform opening an...
