Description

technical field [0001] The invention relates to the fields of power electronics technology and high voltage technology, in particular to a method and device for evaluating the pollution state of an insulator. Background technique [0002] Insulator pollution flashover accidents will seriously affect the safe and stable operation of the power grid. In the research of insulator flashover, the pollution state and pollution level of the insulator surface are important parameters affecting the insulator flashover voltage. Therefore, it is necessary to grasp the accurate insulator pollution degree The level is particularly important for the prevention and control of flashover. The flashover voltage of an insulator is the most direct indicator of the insulation level of the insulator. The value of the flashover voltage directly reflects the insulation performance of the insulator and has the most intuitive reference function. Therefore, the surface pollution of the insulator can be...
