摘要
芳纶纤维增强型绝缘拉杆具有电气绝缘性能优异、机械强度高、质量轻等优点,但是却具有较高的统计故障概率。对两起采用该工艺的绝缘拉杆放电故障进行联合分析,通过建立隔离开关实体三维模型及电场仿真分析,验证了绝缘结构设计的合理性。介绍了芳纶纤维增强型绝缘拉杆的工艺流程,指出层间分离缺陷是运行中绝缘拉杆放电的主要原因,针对层间分离缺陷的影响因素提出了相应的工艺控制措施。
The aramid fiber reinforced insulating pull rod has the advantages of excellent electrical insulation,high mechanical strength and light weight,but it has a high statistical failure probability. The joint analysis of two discharge faults of aramid fiber reinforced insulating pull rods is carried out. The rationality of insulation structure design is verified by establishing three-dimensional model of disconnector and electric field simulation analysis. The author introduces the technological process of aramid reinforced insulating pull rod,points out that the main reason for the discharge of insulating pull rod is the interlayer separation defect,and puts forward the corresponding technological control measures for the influencing factors of interlayer separation defect.
