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.

Abstract

The invention relates to the technical field of circuit breakers, and concretely relates to a transmission position detection structure of a miniature automatic reclosing circuit breaker. The transmission position detection structure includes a shell, wherein a circuit breaker main body is arranged in the shell 1; the circuit breaker main body comprises a driving motor, a PCB, a transmission gearand a circuit breaker handle mechanism. The circuit breaker handle mechanism comprises a handle gear, the driving motor is in transmission connection with a transmission gear through a gear transmission mechanism, a sensing gear which is coaxially arranged with the transmission gear is fixedly installed on the transmission gear, the sensing gear is meshed with the handle gear, and a switching-on and switching-off signal detection module is arranged in the shell. By arranging the opening signal detection module composed of a Hall switch and a microswitch, automatic switching can be carried outto work in high-temperature, high-humidity and high-intensity magnetic field environments, and the reliability and stability of the product are greatly improved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a transmission position detection structure of a small automatic reclosing circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a...
