The invention discloses a miniature electric switch-on-off type circuit breaker. The miniature electric switch-on-off type circuit breaker comprises a miniature circuit breaker body with an insulation outer shell and a switch-on-off handle. The miniature electric switch-on-off type circuit breaker is characterized by further comprising an electric switch-on-off mechanism for driving the switch-on-off handle to conduct reciprocating motion. The electric switch-on-off mechanism comprises a frame body, a gear motor, a transmission gear, a cover nut and a dial wheel, wherein the frame body is fixedly arranged on the insulation outer shell, the gear motor is arranged on the frame body and provided with an output gear, the transmission gear is rotationally arranged on the frame body, the switch-on-off handle is sleeved with the cover nut, and the dial wheel drives the cover nut to conduct reciprocating motion. The output gear drives the dial wheel to conduct reciprocating rotation through the transmission gear, and the dial wheel drives the switch-on-off handle to conduct switch-on-off motion through the cover nut. According to the miniature electric switch-on-off type circuit breaker, the electric switch-on-off mechanism is directly fixedly installed on the outer wall of the insulation shell of an existing miniature circuit breaker body, therefore, remote intelligent control is achieved, the miniature electric switch-on-off type circuit breaker can be used in an intelligent power grid, and due to the fact that the internal structure of the existing miniature circuit breaker body does not need to be changed, manufacturing cost is effectively reduced in specific implementation.
Description
technical field [0001] The invention belongs to the technical field of structural design of small circuit breakers, and in particular relates to an electric opening and closing type small circuit breaker. Background technique [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 future intelligent trend, it is urgent to improve the existing miniature circuit breaker so that it has an electric opening and c...
