AI Technical Summary

Technical Problem

The traditional high-pressure sulfur hexafluoride circuit breaker transmission device adopts a single-action structure, which leads to low operating efficiency and poor reliability, making it difficult to respond quickly and operate stably.

Method used

A double-action transmission device is adopted to realize the opposite direction of the moving contact and the static arc contact through the linkage between the moving contact and the static arc contact by using the double-action transmission mechanism, thereby increasing the opening and closing speed and reducing the operating power.

Benefits of technology

The circuit breaker opening and closing speed is improved, the operating power is reduced, and the closing time is significantly shortened, which improves the reliability and stability of the equipment.
