本文介绍了一种新型的银—石墨纤维型触头材料。叙述了它的挤压、切片、脱碳等工艺。与常规工艺制取的材料相比,该材料不但物理性能、电寿命大为提高,而且保持了抗熔焊性好的优点。对于既要求有可靠的抗熔焊性又要求有较长电寿命的自动开关。是较为理想的触头材料。由于电寿命提高和触头尺寸减小,节银效果明显。 This article describes a new type of silver-graphite fiber contact material. Described its extrusion, slicing, decarbonization and other processes. Compared with the material prepared by the conventional process, the material not only has better physical properties and electrical life, but also has the advantages of good anti-welding property. For both require a reliable anti-soldering but also require a longer electrical life of the automatic switch. Is the ideal contact material. As the electrical life increases and the contact size decreases, section silver effect is obvious.
