A novel reversible thermometric organic material for power transmission line detection application

Abstract

Abstract Due to the inaccuracy of the existing fault detection method caused by the overheating of the equipment of the long-spanning overhead transmission line, this paper creatively proposes a detection method of the reversible thermochromic organic thin film material HCBCC which can be deposited on the equipment or hardware of the transmission line based on the electron transfer mechanism. In this method, the film material made with five components in accordance with the optimal ratio was named HCBCC film, and the coloration performance of the material was determined by UV-Vis absorption spectroscopy, temperature variable infrared spectroscopy, differential scanning calorimetry and other characterization methods. Then, its durability was verified through environmental tests such as high and low temperature, rain and snow, wind and sand, and aging. HCBCC material has the advantages of easy observation, fast color rendering and wide temperature range in the temperature indicator, which not only greatly reduces the intensity of inspection work for staff and can find fault points in time, but also saves a lot of time for the emergency repair of power equipment and provides guarantee for the safe and stable operation of power grid.
