Abstract

The electrical performance of transmission line insulators will decrease dramatically under ice-covered conditions, and ice flashover may occur under operating voltage. There is no direct and effective monitoring method for ice cover on insulators of transmission lines. In this paper, the interface quasi-distributed fibre Bragg grating (FBG) is used to study the positioning detection of glaze icing loads on composite insulators, and a mechanical lever model of single glaze icing load on single umbrella detection with three FBGs is established. Based on this model, a multi-glaze location detection method on multiple umbrella skirts is proposed. Six optical fibres with 13 quasi-distributed FBGs each are implanted into the interface of a 110 kV composite insulator. The minimum load test of FBG for detecting glaze icing load, the FBG axial/circumferential sensing rule test for the glaze, and the weight simulation test and laboratory icing verification test for multi-glazes on multi-umbrellas location detection method are carried out. The results show that the positioning of glaze simulated by weights is accurate, and the positioning of icing in the laboratory is basically correct.

复合绝缘子上釉覆冰载荷的界面准分布式光纤光栅定位检测

在结冰条件下，输电线路绝缘子的电性能会急剧下降，在工作电压下可能发生冰闪。输电线路绝缘子覆冰没有直接有效的监测方法。本文采用界面准分布式光纤光栅(FBG)对复合绝缘子上釉覆冰载荷的定位检测进行了研究，建立了3个光纤光栅单伞检测中单釉覆冰载荷的力学杠杆模型。基于该模型，提出了一种多伞裙的多釉定位检测方法。在110 kV复合绝缘子的界面上植入了6根光纤，每根光纤有13个准分布fbg。进行了FBG检测釉面结冰载荷的最小载荷试验、FBG轴向/周向传感规则试验、多伞定位检测方法上多釉面的重量模拟试验和实验室结冰验证试验。结果表明，砝码模拟的釉料定位准确，实验室中结冰的定位基本正确。
