摘要/Abstract

摘要： 基于光纤传感器测量输变电设备外绝缘污秽度的可行性研究,引入了光波导中的光场分布理论。通过光谱数据分析算法,分析了石英玻璃作为光传感器的各种光能特性,建立了光通量的衰减与盐密间的数学模型,进而研制了基于光传感器的污秽在线监测系统,实现对绝缘子盐密的在线监测。该系统已在天水330 kV输电线路陇西1-2线瓷绝缘子和复合绝缘子测点挂网运行,并取得了良好的监测效果。试验结果表明,该系统能实时、准确地监测输变电设备的盐密值,掌握输变电设备的积污规律,进而指导生产部门对输变电设备的状态清扫,以避免过度检修和检修不足的状况。

Abstract: The optical field distribution theory of optical waveguide was introduced based on the feasibility study of the optical fiber sensor to measure the external insulation pollution degree of the transmission and transformation power equipment. The light energy parameters of quartz glass used as the optical sensor was analyzed by spectral data analysis algorithm and the corresponding relationship between luminous flux attenuation and salt density was set up. Subsequently the optical sensor Pollution Monitoring System was developed to realize the on-line monitoring of insulator salt density. The system has already been applied in Tianshui 330 kV transmission line and the results are satisfied. The test results indicate that the system can timely and accurately monitor the salt density of the transmission and distribution equipment, and guide the production department to clean the transmission and distribution equipment in order to avoid excessive or insufficient maintenance.

Key words: Optical fiber sensing technology, light characteristics, salt density, on-line monitoring
