Problems solved by technology

Most of the double-pole circuit breakers on the market now use two sets of tripping mechanisms, and the knobs of the two sets of tripping mechanisms are connected together. Although this technical solution meets the technical requirements of double-pole circuit breakers, two sets of tripping mechanisms are installed. High mechanism cost, complex installation and large volume

Abstract

A circuit breaker mechanism comprises a knob, a pendulum rod arranged on the knob, a transmission frame driven by the pendulum rod, a rotating frame for driving tripping of the pendulum rod from the transmission frame, and two tripping components for driving the rotating frame respectively, wherein the rotating frame is hinged on the transmission frame; a first tripping convex block and a second tripping convex block are arranged on the two sides of the rotating frame respectively; the tripping components are positioned on the two sides of the rotating frame; pushing parts are arranged on the tripping components; the pushing part on the tripping component on one side drives the first tripping convex block; and the pushing part on the tripping component on the other side drives the second tripping convex block. The circuit breaker mechanism has the advantages of simple structure, few components and sensitive actions; the two tripping components drive the rotating frame respectively, so that the application range of the circuit breaker mechanism is expanded; and sliding pushing parts of a sliding pressure transmission frame are arranged on the tripping components, so that a forcible disconnecting function is enhanced and the performance of a switching disconnecting action is stabilized.

Description

technical field [0001] The invention relates to a circuit breaker mechanism, and the invention also relates to a double-pole circuit breaker using the circuit breaker mechanism. Background technique [0002] At present, there are various types of circuit breakers with different working principles. One type of circuit breaker uses circuit protection mechanisms such as short-circuit current relays and bimetallic strips and tripping mechanisms that cooperate with these protection mechanisms, and sets the moving contacts on the tripping mechanism to monitor the circuit through the circuit protection mechanism. In case of overload, short circuit, etc., the corresponding action is used to drive the tripping mechanism to separate the moving contact from the static contact to realize the disconnection protection of the circuit. [0003] In this type of circuit breaker, the key points of the scheme mainly focus on the linkage and cooperation relationship between the circuit protecti...
