Composite insulator heating reason judgment and disposal method and system

The invention discloses a composite insulator heating reason judgment and disposal method and system. According to an existing method, the heating reason of the composite insulator is judged through the surface temperature distribution characteristics of the composite insulator, the method depends on composite insulator heating case samples obtained on site, and when the sample coverage is limited, the accuracy of the method will be affected. Aiming at the heating defect of the composite insulator on site, the method comprises the following steps: firstly, obtaining a heating map of the composite insulator in an environment with over 85 percent of high humidity and an environment with lower than 70 percent of low humidity on site, and further judging the heating type according to the heating position and the heating temperature difference change of the composite insulator in different humidity environments; and a treatment method is provided by combining whether the surface sheath is intact and the surface ul
