AI Technical Summary
Traditional trip units have low magnetic circuit integration and discrete branch inductors, resulting in large size, which is not conducive to the miniaturization and performance optimization of circuit breakers.
A miniature circuit breaker trip unit based on decoupling integration is adopted. By using a T-shaped moving iron core, an L-shaped stationary iron core and an electromagnetic coil group on a printed circuit board, the independent and integrated design of multiple branch inductors is achieved through the combination of planar magnetic technology and electromagnetic tripping function.
This design achieves a compact circuit breaker design, improves integration, ensures the independence and operational stability of branch inductors, enables rapid mechanical interruption of fault current, and enhances the short-circuit breaking performance and action response speed of the circuit breaker.
