[0038] Embodiment 1

[0039] Traditional detection methods can only monitor the real-time operating status of the circuit breaker controller, failing to detect the status of other components within the circuit breaker. Furthermore, existing monitoring mechanisms require space within the circuit breaker's internal cavity, are structurally complex, difficult to install, and lack standardization. To address this challenge, as shown in the attached... Figure 1 As shown in Figures 2 and 3, this embodiment provides a circuit breaker opening and closing status monitoring mechanism. The circuit breaker opening and closing status monitoring mechanism a is installed in the cavity 201 on the phase-to-phase insulating partition 2 at the bottom of the circuit breaker base 1.

[0040] As attached Figure 4 and 5 As shown, the circuit breaker opening and closing status monitoring mechanism a includes a support base 3. A micro switch 4 is mounted on the support base 3 and located within a cavity 201 on the phase-to-phase insulating partition 2 at the bottom of the circuit breaker base 1. A trigger part 501, capable of triggering the micro switch 4, is provided on the rotating shaft 5 at a position corresponding to the micro switch 4. In this embodiment, as shown in the attached diagram... Figure 8 As shown, the trigger part 501 is a protrusion on the rotating shaft 5 corresponding to the micro switch 4. During the opening and closing rotation of the circuit breaker, the rotating shaft 5 can trigger or disengage from the micro switch 4, thereby outputting the opening or closing signal of the circuit breaker.

[0041] As attached Figure 6 As shown, the micro switch 4 is snapped into the support base 3 via the snap fastener 7 and then integrally mounted within the cavity 201 on the phase-to-phase insulating partition 2 at the bottom of the circuit breaker base 1. The support base 3 is locked onto the bottom back surface of the circuit breaker base 1. (See attached diagram.) Figure 1 and 2 As shown, more specifically, the support base plate 301 of the support seat 3 is locked onto the bottom surface of the back of the circuit breaker base 1, and the support part 302 of the support seat 3 is mounted on the attached... Figure 7a and 7b The microswitch 4 is installed in the cavity 201 on the phase-to-phase insulating partition 2 at the bottom of the circuit breaker base 1. The cavity 201 is located below the rotating shaft 5, and the length direction of the cavity 201 is perpendicular to the rotation center axis of the rotating shaft 5.

[0042] Example 2

[0043] As attached Figures 9 to 13 As shown in this embodiment, the support base 3 in the circuit breaker opening and closing status monitoring mechanism a includes a circuit board 6, which serves as a support. The micro switch 4 is fixed on the surface of the circuit board 6, and the circuit board 6 is locked onto the bottom back surface of the circuit breaker base 1.

[0044] Specifically, the circuit board 6 includes an upper circuit board 602 and a lower circuit board 601, the micro switch 4 is fixed on the upper circuit board 602 through pin welding of the micro switch 4, the upper circuit board 602 and the lower circuit board 601 are respectively provided with corresponding plug interfaces, the upper circuit board 602 and the lower circuit board 601 are plug-fixed together, the lower circuit board 601 is locked on the back bottom surface of the circuit breaker base 1, and the upper circuit board 602 and the micro switch 4 are in the cavity 201 on the interphase insulation partition wall 2 of the bottom of the circuit breaker base 1. The opening and closing signal of the micro switch 4 is transmitted to the upper circuit board 602 through the pin, then transmitted from the upper circuit board 602 to the lower circuit board 601 through the plug interface, and then transmitted to the external required signal position, such as a controller, through the lower circuit board 601. The plug interface can be a pin and a corresponding pin.

[0045] The circuit breaker opening and closing state monitoring mechanism is arranged on the partition plate between phases of the circuit breaker base, does not occupy the accessory cavity space and the phase space in the circuit breaker, simultaneously simplifies the installation structure of the circuit breaker opening and closing state monitoring mechanism, reduces the installation difficulty, and is easy to manufacture.
