Embodiment 1
[0020] refer to Figure 1-7 , a small automatic reclosing circuit breaker transmission position detection structure, including a housing 1, a circuit breaker main body is installed in the housing 1, the circuit breaker main body includes a driving motor 2, a PCB board 17, a transmission gear 3, and a circuit breaker handle mechanism, The handle mechanism of the circuit breaker includes a handle gear 5. The drive motor 2 is connected to the transmission gear 3 through the gear transmission mechanism. meshing, the housing 1 is provided with an opening and closing signal detection module. The driving motor 2 drives the transmission gear 3 through the gear transmission mechanism, the transmission gear 3 drives the sensing gear 4 to rotate, and the sensing gear 4 and the electric handle gear 5 rotate.
[0021] The opening and closing signal detection module includes a first permanent magnet 10, a first permanent magnet 10 is embedded and installed on the transmission gear 3, and a...
Embodiment 2
[0025] refer to Figure 1-7 , As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the first permanent magnet 10 and the second permanent magnet 11 are made of alloy permanent magnet materials. The gaps of the housing 1 are all waterproof and dustproof.
[0026] Alloy permanent magnet materials not only have high hardness and mechanical properties, but also have strong anti-demagnetization ability; by waterproofing and dustproofing the gaps in the shell 1, dust and moisture can be effectively prevented from entering the shell 1 The influence of components.
