摘　　要：绝缘子清洗机器人在绝缘子串上开展清洗作业时,可能会影响输电线路上的静磁场环境,导致周围静磁场产生变化,其磁场强度可能越限。因此需要开展机器人绝缘子串清洗作业的静磁场分析。针对机器人清洗110 kV输电线路上的水平悬式绝缘子情况,基于ANSYS有限元分析软件分析机器人到达绝缘子串3处位置时的静磁场强度大小以及分布情况;同时为了降低机器人对周围静磁场环境的影响,对机器人的制作材料进行了优化。静磁场分析结果表明,在110 kV输电线的输送功率为10~50 MW范围内,机器人移动到绝缘子串3处位置时的磁感应强度均达到了限值;比较了铝质材料和镀铜材料的静磁场强度,结果表明,机器人制造材料更换为磁导率相对较低的镀铜材料时,可以减少周围磁场强度的大小,缩小机器人移动到不同位置时的磁场强度相对变化量,降低机器人对输电线路电磁环境的影响。When the insulator cleaning robot carries out cleaning operation on the insulator string,it may affect the static magnetic field environment on the transmission line,resulting in changes in the surrounding static magnetic field,and its magnetic field strength may exceed the limit.Therefore,it is necessary to carry out static magnetic field analysis of robot insulator string cleaning operation.In view of the robot cleaning the horizontal suspension insulator on the 110 kV transmission line,based on the ANSYS finite element analysis software,the magnitude and distribution of the static magnetic field intensity when the robot reaches the three positions of the insulator string were analyzed;at the same time,in order to reduce the impact of the robot on the surrounding static magnetic field environment,the manufacturing materials of the robot were optimized.The static magnetic field analysis results show that the magnetic induction intensity of the robot moving to three positions of the insulator string reaches the limit value when the transmission power of the 110 kV transmission line is 10~50 MW.The static magnetic field strength of aluminum material and copper-plated material was compared.The results show that when the robot manufacturing material is replaced with copper-plated material with relatively low permeability,the size of the surrounding magnetic field strength can be reduced,the relative variation of the magnetic field strength when the robot moves to different positions can be reduced,and the impact of the robot on the electromagnetic environment of the transmission line can be reduced.
