Abstract

The invention discloses an automatic switching-on and switching-off device of an intelligent miniature circuit breaker. A worm is installed on a rotating shaft of a driving motor, the worm is used incooperation with a meshing gear set, a half gear in a fourth gear is used in cooperation with a handle driving gear, and the handle driving gear is installed on a handle driving square shaft; a straight gear of the first gear is mounted above a helical gear; a tripping shifting block is installed on the fourth gear, a tripping rod is installed on a side surface of the fourth gear, the tripping rodis used in cooperation with the tripping shifting block, and the tripping rod is fixedly installed on a body linkage shaft; the handle driving gear is provided with a switching-on auxiliary elastomerwhich is used in cooperation with the half gear of the fourth gear; and the body linkage shaft and the handle driving square shaft are connected with the circuit breaker. The device is reasonable instructural design, reliable in action in use and very high in practicability; and switching-on reliability of the product can be improved, a service life of the product is prolonged, and accidents arereduced.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an automatic closing and opening device for an intelligent small circuit breaker. Background technique [0002] Common automatic closing and opening devices of circuit breakers use a motor-driven gear system to increase the output torque of the motor and reduce the speed to provide power for closing and opening of the circuit breaker. The circuit breaker mechanism is driven to close by the gear mechanism, but the gear rotation angle must be consistent with the closing angle of the product handle, so that the circuit breaker mechanism can be completely closed, which requires high manufacturing precision and matching precision of the internal parts of the product. , not only increases the production cost of the product, but also causes gear teeth to be broken due to insufficient closing of the circuit breaker or excessive closing angle; and the common closing and opening device of...
