摘　　要：500kV变电站GIS接地线挂接难度大、风险高、稳定性差,一旦脱落将导致严重接地事故,造成人员伤亡,在电力运维检修工作中需全面重视。为解决上述问题,设计一体弯折成型的“D”字挂环,其本体采用铜质材料制成,配接地环夹和导线夹,支持360°调整挂线,适用于500kV变电站GIS接地线挂接的多场景作业,值得深入研究和推广应用。The GIS earth wire hang of 500kV transformer substation is of great difficulty,high hazard and poor stability.A“D”hang hoop of an organic whole bending fold is designed in the paper.It′s body is made of copper material,matching earth hoop clamp and conducting wire clamp to support 360°to adjust hang wire,which is suitable for multiple field work of GIS earth wire hang of 500kV transformer swbstation.It is worth going deep into studying and spreading application.
