摘　　要：电力金具发生断裂事故较为常见,文章通过对110 kV杨群Ⅰ回"Z"型挂板断裂事故现场勘察,采用材料机械性能测试、显微组织分析、断口扫描电镜分析、能谱分析等方法,对金具断裂原因进行研究,证实断裂与制造、安装等环节有关,并提出了针对性建议。Electrical fittings frequently occurs fracture accident. Through on-site investigation of ＇ Z＇ type hanging board fracture accident in 110kV Yangqun I circuit, the paper adopts mechanical property testing, and microstructure analysis, fracture scanning electron microscope analysis, spectrum analysis , and makes study on the reason of electri- cal fittings fracture, thus confirms the fracture concerned with the manufacture, installation and other parts, and puts forward specific suggestions.
