Abstract

The invention discloses a molded case circuit breaker, which comprises a shell and is characterized in that a reclosing mechanism and a reduction gearbox mechanism in linkage with the reclosing mechanism are arranged in the shell. The reclosing mechanism comprises an external gear in linkage with the reduction gearbox mechanism, a linkage wheel is arranged on the external gear, a connecting rod is connected to the linkage wheel, the other end of the connecting rod is connected with the handle, and when the handle carries out one-time opening and closing operation, the linkage wheel rotates by 360 degrees. According to the problems existing in the prior art, a reclosing mechanism which is different from an existing reclosing mechanism is adopted, the horizontally-installed motor is matched with the speed reducer, and the electric opening and closing function is achieved for the reclosing mechanism.

Description

technical field [0001] The invention belongs to the field of low-voltage electrical technology and relates to a molded case circuit breaker. Background technique [0002] The reclosing mechanism of a molded case circuit breaker is generally opened and closed by a motor-driven gear set, but most of the current molded case circuit breakers are set up to drive the gear set by a vertical motor, which will lead to The length of the molded case circuit breaker in the vertical direction increases, and the overall volume becomes larger. Secondly, most of the gear sets are exposed in the housing, resulting in poor protection and reduced gear life. Contents of the invention [0003] The purpose of the present invention is to provide a molded case circuit breaker to solve the problem of increased volume caused by the existing motor installation method. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a molded case circu...
