AI Technical Summary

Technical Problem

The contact pressure of traditional relay contact bridges is difficult to adjust and cannot be adjusted according to actual working conditions, resulting in pressure attenuation caused by wear and deformation, which affects service life and reliability.

Method used

A relay contact bridge with a silver layer is designed. A pushing component including a threaded rod and a top block is used. By rotating the threaded rod, the top block is driven to push the contact bridge to deflect, thereby increasing the contact pressure. A graphene coating is applied to the surface of the silver layer contact to improve heat conduction and arc resistance. Heat dissipation grooves are provided on the outside to improve heat dissipation performance.

Benefits of technology

This improved the contact pressure between the silver layer contacts and the stationary contacts, extending the relay's service life, improving heat conduction and heat dissipation, enhancing arc resistance, and reducing the risk of equipment failure.
