Operation mechanism provided with detection switch sensor

Abstract

The invention discloses an operation mechanism provided with a detection switch sensor. The operation mechanism includes a housing and a control module. A motor is mounted in the left lower corner ofthe housing and a worm rod is arranged on the motor. A turbine is engaged with the worm rod. A first transmission gear is arranged on the right side of the turbine. A third transmission gear is arranged on the upper end of the first transmission gear. A central shaft is arranged in the three transmission gear and a second transmission gear is mounted on the central shaft. The right upper corner ofthe third transmission corner is provided with a handle gear. The control module is provided with a first detection switch and a third detection switch while grafting board is provided with a seconddetection switch. Positions for automatic disengagement, engagement and engagement escape of a circuit breaker are implemented further. The detection switches are insusceptible to external electromagnetic field interference and has advantages of small contact interval, short action stroke, small pressing force, high switching speed, long mechanical life, small size and the like, requirements for use performance of an automatic engagement and disengagement circuit breaker are met completely and product performance stability and use safety are improved substantially.

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 ...
