Abstract

The present invention discloses a breaker operation component, comprising a handle, a transmission mechanism, an upper moving contact terminal, a lower moving contact terminal and a steering mechanism. The handle can use the transmission mechanism to drive a contact terminal end of the upper moving contact terminal to move towards a preset direction for switching on, and simultaneously use drivingof the transmission mechanism and steering transmission of the steering mechanism, to push a contact terminal end of the lower moving contact terminal to move reversely along a preset direction for switching on. In an operating system of the breaker operation component, the upper moving contact terminal and the lower moving contact terminal move in opposite directions to implement switching on, and switching-on positions are far away from each other, to help heat dissipation. Correspondingly, in this case, a field direction of the N pole plays a beneficial role on the L pole and enhances an electric arc movement speed in a break-time, so that a breaking capacity of a product is improved.

Description

technical field [0001] The present invention relates to the technical field of electrical equipment, and more specifically, relates to a circuit breaker operating assembly. Background technique [0002] At present, in the circuit breaker of the prior art, the upper and lower moving contacts of the contact structure move in the same direction under the control of the bracket, which has a certain influence on the breaking performance. The heat generated at the contact is large and concentrated, which is not conducive to heat dissipation and leads to temperature rise. [0003] To sum up, how to effectively solve the problem of high and concentrated heat generation at the moving contact leading to temperature rise is an urgent problem for those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide an operating assembly for a circuit breaker, which can effectively solve the problem of high and concentrated hea...
