Problems solved by technology

[0002] At present, the opening position and closing position of automatic opening and closing circuit breakers are mostly controlled by Hall switches, but Hall switches are controlled by magnetic fields, and their sensitivity is proportional to the magnetic induction intensity of an external magnetic field, so they cannot adapt to complex The electromagnetic field environment is easy to be interfered by the external electromagnetic field and cause malfunction, which greatly reduces the reliability and safety of the product.

Abstract

The invention discloses an operation mechanism of a circuit breaker. The operation mechanism comprises a shell and a control module, wherein a motor is mounted at the left lower corner of the shell; aworm is arranged on the motor; the worm is meshed with a turbine; a first transmission gear is arranged on the right side of the turbine; a third transmission gear is arranged at the upper end of thefirst transmission gear; a central shaft is arranged in the third transmission gear; a second transmission gear is mounted on the central shaft; a handle gear is arranged at the right upper corner ofthe third transmission gear; a first detection switch is mounted on the handle gear; a second detection switch and a third detection switch are arranged on a control module. Therefore, positions of automatic separation, closure, closure abdication, and the like, of the circuit breaker, can be achieved, the detection switch is not interfered by an external electromagnetic field and has the advantages of being small in contact distance, short in action stroke, small in pressing force, rapid in on / off operation, long in mechanical service life, small in appearance size, and the like, use property requirements of an automatic separation / closure circuit breaker can be completely met, and the property stability and the use safety of products can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of circuit breaker opening and closing control, in particular to an operating mechanism with a detection switch sensor. Background technique [0002] At present, the opening position and closing position of automatic opening and closing circuit breakers are mostly controlled by Hall switches, but Hall switches are controlled by magnetic fields, and their sensitivity is proportional to the magnetic induction intensity of an external magnetic field, so they cannot adapt to complex The electromagnetic field environment is easy to be interfered by the external electromagnetic field and cause malfunction, which greatly reduces the reliability and safety of the product. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a solution: an operating mechanism with a detection switch sensor, including a housing and a control module, a motor is provided at ...
