Abstract

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
