摘要
电力通信特种光缆OPGW故障类型主要分为外部故障和内部故障,外部故障主要表现为光缆断股、散股,内部故障主要表现为光缆断芯、纤芯高损。造成光缆外部故障的主要原因通常有外力破坏、覆冰、雷击等,造成光缆内部纤芯故障的原因除了外力破坏外,还与光缆承受负载密切相关。文章以发生在500 kV线路OPGW光缆的断芯故障为例,对光缆在超负载情况下导致纤芯损伤进行了较为全面的分析,并对今后类似故障提出改进建议。
The typical fault of special OPGW Optical Cable in Electric Power Communication is mainly composed of external fault and internal fault. External fault mainly shows the loose and broken strand of Optical Cable, while the internal fault mainly shows core fretted or core broken. Coating ice, lightning strike and damage from outside destroy are usually the main causes of the external fault. Besides the damage from outside destroy, the internal fault is closely related to overloading. Taking the fault of OPGW core broken of 500 kV circuit as an example, the paper has provided an across-the-aboard analysis on core damage of optical cable caused by overloading. Finally the suggestion was given in this field for future improvement.
