Researches On Infrared Diagnostic Technology Of Electric Equipments And Application In Electric Power Grid Of Si Chuan

The infrared diagnosing techniques, which have been more and more popularly applied, played an important role in interior and exterior Fault diagnosing for electrical equipments. The main characters of infrared diagnosis untouching character and inspecting for running equipments, determine that it diagnosing result can be affected by external environment and the judging principles. For this reason, enhancing the accuracy and applying affects of infrared diagnosing technique have high significance. Thus, the research on infrared Fault diagnosing for electrical equipments is of great project practical value.This text setting out from the highly safe and reliable basic demand that runs of the modern power system, for the deficiency of the traditional maintain way of running equipment in electric power, propose the realistic significance of the research and practice the infrared diagnosing techniques in power system. This text draws the basic principle of infrared diagnoses based on the primary knowledge of infrared radiation, and analyse the imaging principle of infrared devices; From the view of infrared diagnostic technology we discuss the fault models and the principium of infrared diagnosis on electrical equipments; Then this paper research the diagnosis of electrical equipments fault by using infrared devices, obtain the hot picture atlas of equipment fault and analysis the hot picture atlas; The text analyse the various kinds of possible factor which might effect the results of infrared diagnosing in electrical equipments, and propose correspondingly countermeasure against these factor in order to improve the accuracy of measurement; Finally, by using infrared diagnosing techniques analyse and diagnose the interior or exterior fault in part of transformers and arresters in electric network of Si Chuan, and the results obtained from the text accord with practice.The paper key research has analyzed main electrical equipment each kind of in interior and exterior fault infrared hot picture the characteristic, the model infrared atlas and carries on qualitative, the quota and the localization diagnosis distinction method as well as the infrared diagnosis technology in the Sichuan electrical network model application.The main conclusion obtained in this paper: The equipment failure infrared diagnosis technology is the modern electric power industry development and the traditional examination service method important supplement, its examination processsimple, finally judged clearly, fast direct-viewing, safe and reliable. The infrared diagnosis technology in the Sichuan electrical network success application show the infrared diagnosis technology regarding the power equipment in exterior flaw examination and the diagnosis which the effect is remarkable suits to promotes the application in the electrical power system.
