Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0042] like figure 1 and figure 2As shown, this embodiment provides a circuit breaker equipped with an automatic opening and closing control device. The circuit breaker adopts 4 modulus circuit breakers with 1 N pole and 3 P poles. The circuit breaker includes a housing 1 , a circuit breaker handle 2 and a circuit breaker operating module 3 . The circuit breaker handle 2 includes a plurality of handle units 21, and one handle unit 21 is correspondingly installed on a module of the circuit breaker. Each handle unit 21 includes a handle gear 211, and the handle gear 211 is used to ...

The invention relates to an automatic switching-on and switching-off control device and a circuit breaker. The circuit breaker comprises a shell, a circuit breaker handle and a circuit breaker operation module. The automatic switching-on and switching-off control device is installed in the shell and comprises a motor and a gear transmission module. The motor is installed in the shell, and a firstworm is arranged on a transmission shaft of the motor. The gear transmission module comprises a first connecting gear, a second worm and a combined gear, the second worm is installed in the shell, thefirst connecting gear is installed at one side end of the second worm, the first connecting gear is connected with the first worm, and the second worm is connected with the combined gear. Compared with the prior art, switching-on and switching-off of the circuit breaker can be achieved without additionally adding an extra modulus, the structure is compact, the overall size of the circuit breakercan be effectively controlled, and the installation space is saved; the gear transmission module improves the transmission ratio, reduces the power requirement for the motor, and improves the workingstability.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an automatic opening and closing control device and a circuit breaker. Background technique [0002] With the development and progress of technology, circuit breakers with automatic opening and closing functions are more and more widely used in smart grids, such as self-resetting overvoltage and undervoltage protectors and prepaid reclosing circuit breakers, etc., which can realize remote control of circuit breakers Switch on and off. However, current circuit breakers with automatic opening and closing function realize automatic opening and closing by adding a separate module, which increases the overall volume of the circuit breaker, which is not conducive to the development of circuit breakers in the direction of miniaturization. [0003] For example, the Chinese invention patent whose publication number is CN105609383A discloses a kind of opening and closing operatio...
