[0002] At present, the prepaid intelligent power supply metering system is being widely used. The low-voltage circuit devices currently used in this system are mainly low-voltage molded case circuit breakers of the electric opening and closing type. It is easier to realize the addition of an electric opening and closing mechanism, but the existing low-voltage miniature circuit breakers commonly used in households, such as C45 or DZ47 miniature circuit breakers, are limited by their own structure, volume and installation methods, as well as man-made Neglected factors have not been applied to this system. In order to meet the trend of intelligence in the future, it is urgent to improve the existing miniature circuit breaker so that it has an electric opening and closing mechanism, so that it can be applied to the prepaid system.

The invention discloses an electric switch-off and switch-on mechanism for a small-sized circuit breaker. The electric switch-off and switch-on mechanism for the small-sized circuit breaker comprises a frame body, a gear motor, a transmission gear, a sleeve cap and a stir wheel, wherein the gear motor is arranged on the frame body and is provided with an output gear, the transmission gear is arranged on the frame body in a rotation mode, a switch-off and switch-on handle is sleeved with the sleeve cap, the stir wheel is used for driving the sleeve cap to carry out reciprocating rotation, the output gear drives the stir wheel to carry out reciprocating rotation through the transmission gear, the stir wheel drives the switch-off and switch-on handle to carry out switch-off motions and switch-on motions through the sleeve cap, and the switch-off and switch-on handle is externally connected with the small-sized circuit breaker. When the electric switch-off and switch-on mechanism for the small-sized circuit breaker is used, due to the fact that an installing plate can be directly fixed to the outer wall of an insulating shell body and one side of an existing small-sized circuit breaker, namely the whole electric switch-off and switch-on mechanism and the small-sized circuit breaker can be fixed together, remote intelligent control over switch-off and switch-on of the small-sized circuit breaker can be achieved, the electric switch-off and switch-on mechanism for the small-sized circuit breaker can be applied to an intelligent power grid, and due to the fact that the internal structure of an existing small-sized circuit breaker body does not need to be changed, cost is effectively reduced in the specific implementation process.
Description
technical field [0001] The invention belongs to the technical field of electric opening and closing structure design, and in particular relates to an electric opening and closing mechanism for a small circuit breaker.
