高压真空断路器用熔渗法CuMoCr触头材料的制备工艺

Manufacture of Infiltrated CuMoCr Contact Material for High-voltage Vacuum Circuit Breakers

介绍了高压真空断路器用熔渗法CuMoCr触头材料的制备工艺。研究了原材料预处理温度对Cu粉、Mo粉含氧量的影响,以及Cu粉与MoCr粉的混合比例对熔渗后坯件体积变化的影响,并对结果进行了分析。

The manufacturing process of CuMoCr contact material used for high-voltage vacuum circuit breakers is introduced. The effect of the raw material pretreatment temperatures on the oxygen contents of copper powder and molybdenum powder, and the effect of the proportions of copper and molybdenum chromium in the CuMoCr mixture powder on the blank volume change after infiltration were studied. The experimental results are theoretically analyzed.
