摘　　要：为了满足新疆与西北主网联网750 kV第二通道输变电工程建设需要,研究了750 kV输电线路四分裂跳线系统。采用理论计算的方法得出了跳线的电场强度,确定了子导线型号,根据风偏角计算结果给出了跳线系统的参数,同时结合工程需要开发了跳线四变六转换器和加强抗磨型间隔棒等配套金具。750 kV四分裂跳线系统通过了相关试验及鉴定,能够满足工程使用要求。In order to satisfy the construction need of the 750 kV transmission and transformation project for the connection of Nowthwest grid and Xinjiang grid, the rigid jumper of quadri-split conductors in 750 kV transmission line was studied. The type of sub-conductor was determined through the theoretical calculation of jumper＇ s electric field strength, and the parameters of the jumper system were given based on results of wind yaw angle calculation. Then, this paper developed the complete fittings for the engineering requirements, such as the ＇ four to six＇ converter of jumper, strengthened anti - Wear type spacer, et al. Through the testing and identification, it is shown that the jumper system of 750 kV quadri-split conductors can meet the engineering requirements.
