摘　　要：树线矛盾是造成配电线路接地或断线故障的主要原因,修枝虽然可以短期缓解树线矛盾,但因受绿化管理部门管理和维护,往往受申报审批流程等影响,不能及时开展,存在故障进一步扩大,造成安全隐患,影响线路正常运行和供电可靠性。而且目前缺少相应既便于巡检又耐磨的遮蔽管对树线矛盾处的架空导线进行绝缘防护,因此提出了一种用于防止树线矛盾的绝缘遮蔽管设计,减少树线矛盾对架空配电线路的影响,提升巡检效率,重点介绍该遮蔽管的结构设计和应用优势。Tree line contradiction is the main cause of grounding or disconnection faults in distribution lines.Although pruning can alleviate the contradiction of tree line in the short term,due to the management and maintenance of the greening management department,it is often affected by the declaration and approval process,and cannot be carried out in time,and the failure is further expanded,causing potential safety hazards and affecting the normal operation of the line and the reliability of power supply.Moreover,there is currently a lack of corresponding shielding pipes that are both convenient for patrol inspection and wear-resistant to protect the overhead conductors at the contradiction of the tree line.Therefore,an insulating shielding pipe design for preventing tree line contradiction is proposed,which reduces the influence of tree line contradiction on overhead distribution lines and improves the efficiency of patrol inspection.The structural design and application advantages of this shielding tube are highlighted.
