【 摘 要 】

At present, due to the relatively large insulation gap of UHV(Ultra High Voltage) equipment, the traditional hand-held capacitive electroscope is difficult to operate; the non-contact electroscope is mainly based on the principle of electromagnetic induction, and the reliability is poor in complex areas such as substations and other electromagnetic environments. The power verification problem of AC/DC UHV transmission and transformation equipment has not been effectively solved. In order to optimize and solve the above problems, this research conducts performance testing and reliability analysis for new inorganic electrochromic materials, and uses the color change of inorganic materials to indicate the electrification state of power transmission and transformation equipment, thereby realizing the electricity inspection function. In this project,ZnS Electro-luminescent materials and GaN luminescent materials were prepared, which were packaged into electroscope identification, and the application scheme of electroscope identification on UHV power transmission and transformation equipment was determined. The field practice shows that the electroscope identification prepared by this project can realize spontaneous luminescence discoloration in the electric field, and can effectively indicate the charging state of the equipment, and the effect is very obvious. Thereby effectively solving the problem of power inspection of UHV power transmission and transformation equipment.The economic and social benefits are huge and the application prospects are wide.
