AI Technical Summary

Technical Problem

The electromagnetic system of existing switching devices can only drive the contact system from one end of the moving iron core, which limits the number of contact systems. Furthermore, there is only one magnetic gap between the stationary iron core and the moving iron core, which affects the driving force of the moving iron core.

Method used

The design incorporates at least two magnetic gaps between the stationary and moving iron cores, with the linkage component passing through the central hole, allowing both ends of the linkage component to be used to drive the contact system. The linkage component and the moving contact assembly are connected by a clamping structure, enhancing connection stability.

Benefits of technology

This enables the electromagnetic system to drive more contact systems simultaneously, ensuring the driving force of the moving iron core and improving the connection stability between the linkage and the moving contact assembly.

Abstract

An electromagnetic system and a switching device, the electromagnetic system comprises a coil assembly, a static core and a moving core, the coil assembly comprises a coil framework and a coil wound outside the coil framework, the static core is fixedly arranged on the coil framework and arranged along the outside of the coil assembly, the moving core slides through the central hole of the coil framework and leaves at least two magnetic gaps between the static core, the moving core is also connected with a linkage, the linkage slides through the central hole, and both ends of the linkage extend to the outside of the both ends of the central hole as driving parts respectively. In the utility model, there are at least two magnetic gaps between the static core and the moving core, the driving force of the moving core is guaranteed, the design that the linkage penetrates the central hole makes that both ends of the linkage can be used for driving the contact system, and the electromagnetic system can drive more contact systems simultaneously.
