ABSTRACT:
A buffering mechanism for a gas circuit breaker includes a center piece which includes two protrusions extending from two ends thereof and two match surfaces are defined in two opposite sides of the center piece. Two side boards each have a pivot hole and a slot defined therethrough, the two protrusions of each end of the center piece are pivotably engaged with the pivot hole and the slot respectively. A plurality of impact plates are engaged with the two match surfaces of the center piece. When the impact plates are hit by the two links of the Y-shaped link mechanism of the gas circuit breaker at different times, the center piece is pivoted along the slots to absorb impact forces from the two links.
