Abstract

A tripping link mechanism of an electrically operated device comprises a tripping link member (1), an electrically operated handle and a driving gear (3). The mechanism is characterized in that the tripping link member (1) comprises a tripping link rod (101), the tripping link rod (101) is mounted on a tripping installation shaft (102), one end of the tripping link rod (101) is provided with a tripping link column (103), the upper end of the tripping link column (103) is provided with a tripping link groove (104), the other end of the tripping link rod (101) is provided with a limiting boss (106), the inner side of the limiting boss (105) is provided with a tripping surface (106) on the surface of the tripping link rod (101), and the lateral side of the driving gear (3) is provided with atripping boss (301) corresponding to the limiting boss (106). According to the mechanism, the electrically operated handle and the driving gear are linked with the tripping link member (1), the mechanism can be assembled with a circuit breaker in a disconnected state, the tripping link member has no influence on the circuit breaker when a breaker body moves, and the tripping reliability and stability are ensured.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker trippers, and in particular relates to a tripping linkage mechanism of an electric operating device. Background technique [0002] The opening and closing actions of traditional miniature circuit breakers and switches require manual operations. With the development of smart grid, there is an urgent need for small circuit breakers and switch products that can reliably realize automatic opening and closing. Therefore, electric operating devices that are used in conjunction with miniature circuit breakers and switches and can drive miniature circuit breakers and switches to open and close have appeared on the market. By sending instructions to the electric operating device, it can realize the automatic opening and closing of the small circuit breaker and the switch without manual operation, which effectively saves manpower and material resources, and is widely used. [0003] In the electric...
