一种轻量化断路器操作机构
By designing a lightweight circuit breaker operating mechanism, the separation of the moving contact and the stationary contact is accelerated by using magnetism and a transmission system, and the arc is extinguished in the arc-extinguishing chamber. This solves the problem of slow separation speed of the stationary contact and improves the breaking speed and safety of the circuit breaker.

AI Technical Summary
The separation speed between the stationary and moving contacts of existing lightweight circuit breakers is not fast enough, resulting in poor breaking performance.
A lightweight circuit breaker operating mechanism was designed. The magnetic field generated by the coil overcomes the tension of the compression spring, causing the metal cylinder to drive the ejector pin to strike the rotating plate. This, in turn, accelerates the separation of the moving contact and the stationary contact through the linkage and gear transmission system. The contraction force of the spring is used to accelerate the rotation of the rotating shaft, achieving rapid separation of the moving contact and the stationary contact. At the same time, the arc is extinguished by the metal grid in the arc-extinguishing chamber.
It improves the breaking speed of the circuit breaker, ensures that the arc is extinguished in the arc extinguishing chamber, avoids fire risk, and enhances the protection performance of the circuit breaker.
