爆炸式高压断路器载流体开断过程研究

Studies on the Expanding-Fracture Process of Current Carrier of the ExplosiveHigh-Voltage Short-Circuit Protector

以载流能力为 1 2 50 A的铜管载流体为研究对象 ,实验研究了爆炸式高压断路器载流体开断过程。利用描述动态破坏过程的损伤度函数 ,理论分析薄壁铜管载流体在爆炸膨胀运动下发生贯穿性断裂的瞬间过程和时间 。

With the 1250 A current carrier probability,it is studied the current carriers of explosive high-voltage short-circuit protectors. A damage-level function is proposed in this paper. Starting from this function,the expanding-fracture processes of current carriers can be studied. The complete-fracture time of current carrier can be obtained the same results as experiments.[
