摘　　要：高压直流继电器因独特的结构和灭弧系统,具备很强的短路分断能力和安全保护功能,广泛应用于新能源汽车和充电桩领域。结合X荧光光谱和能谱分析得出:所分析的DC 750 V、250A高压直流继电器动、静触点属于同一种材料,触点材料的金相组织均匀,主要成分为Cu,剩余成分Te,含量约为0.3%。Because of unique structure and arc extinguishing system,high-voltage DC relays have strong short-circuit breaking ability and safety protection functions,and are widely used in the fields of green car and charging piles.By combining X-ray fluorescence spectroscopy and energy spectrum analysis,it can be concluded that:The dynamic and static contacts of the DC 750 V,250 A high-voltage relay analyzed in this article belong to the same material,and the metallographic structure of the contact material is uniform.The main component is Cu,while the remaining component is Te,with a content of approximately 0.3%.
