AI Technical Summary
Existing longitudinal magnetic contact structures suffer from problems such as dispersed arc initiation positions, disordered arc expansion, and poor matching between magnetic field distribution and arc expansion during breakage, leading to localized contact ablation and insufficient breakage stability.
A central arc-initiating electrode is used to achieve precise positioning of the arc initiation position, and the arc is guided to expand along the annular path through an annular groove. Combined with an inertial rotation drive component and a discrete longitudinal magnetic generation component, they work together to control the arc expansion path and magnetic field strength.
It achieves orderly arc expansion and dynamic magnetic field matching, avoiding arc accumulation and contact erosion, improving breaking efficiency and stability, and extending contact life.
