Description

Technical Field

[0002] The contact is one of the key components of the switchgear. According to the structure and working characteristics, it can be divided into three categories: breakable contact, sliding contact and fixed contact. The main performance and life of the switchgear depend to a large extent on the quality of the contact material. The contact material is usually required to have good conductivity, low contact resistance, high resistance to fusion welding, high resistance to arc erosion and resistance to material transfer. For vacuum contact materials, it is also required to have a small cutoff value, high pressure resistance and high breaking capacity. The microstructure of the contact material has an important influence on its macroscopic performance. The electrical properties of the contact material, such as resistance to fusion welding, arc ablation resistance and pressure resistance, are not only related to the composition of the contact material, but also to the size of the grains of the constituent materials.

However, in the traditional processing method, the processing position is directly exposed to the outside, and the debris generated during the processing will directly splash out, causing injuries to the operators.
