不同敷设方式对分布式光纤监测变压器绕组变形的影响研究
|
摘要
为将分布式光纤传感技术应用于变压器绕组变形监测,文中对基于不同敷设方式的光纤监测变压器绕组变形进行了研究,设计并制作了内径侧、外径侧和表面敷设分布式光纤的变压器绕组模型,并对电磁线结构和绕组绕制工艺进行了相应的改进。最后,对上述3种绕组模型进行了局部变形试验,并利用基于布里渊散射原理的分布式光纤应力监测系统对其应变分布进行了监测和评估。结果表明,敷设于绕组外径侧的分布式光纤预应变较大,测量结果的重复性也较差;敷设于绕组内径侧和表面的分布式光纤预应变较小,应变分布较均匀,且测量结果重复性较好;但是,当分布式光纤敷设于绕组外径侧和内径侧时,工程实现较复杂且对绕组原有结构改变较大。综合评估可得,表面敷设最适合作为分布式光纤敷设方式应用于变压器绕组变形监测,绕组内径侧敷设次之,绕组外径侧敷设最差。
In order to apply distributed optical fiber sensing technology to deformation monitoring of transformer windings,this paper researches the transformer winding deformation on different laying modes of fibers. In this pa-per,the transformer winding model of distributed fiber is laid on the inner diameter side,outer diameter side andsurface. These models are used to simulate the winding deformation in practical operation. The process of transformerwinding has been corresponding improved. When the winding is partially deformed,the optical fiber strain will bemeasured by Brillouin Optical Time Domain Reflectometer(BOTDR). The results show that the distributed optical fi-ber laid on the outer diameter side of the winding has large pre-strain and the repeatability of the measurement re-sults is poor. The distributed optical fiber laid on the inner diameter side and the surface of the winding has less pre-strain,uniform strain distribution,and the reproducible results. However,when the distributed optical fiber is laidon the outer diameter side and the inner diameter side of the winding,the engineering implementation is complicatedand the original structure of the winding is greatly changed. In a word,the fiber laid on the winding surface is mostsuitable for deformation monitoring of transformer windings,which followed by laying on the inner diameter side of the winding. The worst method is the outer diameter side of the winding.
