AI Technical Summary
When existing magnetically controlled drive mechanisms are used in low-voltage applications, the contact movement mode is different, which cannot give full play to the advantages of magnetic control mechanisms. In addition, the breaking capacity of single-break switches is poor, and they cannot effectively protect places requiring rapid protection.
The design incorporates a double-break air switch with a double-break moving contact connected to an insulating component. Driven by a magnetic control mechanism and combined with double arc-extinguishing chambers, the vertical movement of the moving contact is achieved. By utilizing the efficient driving characteristics of the magnetic control mechanism, the energy carried by a single break is reduced, thereby increasing the breaking capacity.
It achieves higher mechanical efficiency, faster and more thorough arc extinguishing, strong breaking capacity, compact structure, and long service life, making it suitable for rapid protection in low-voltage power distribution.
