Embodiment Construction
[0022] figure 1 It represents an operation flow chart of the present invention. In this embodiment, step 101: select at least one measurement location according to the geographical distribution of power transmission and transformation equipment. Step 102: At each selected measurement location, hang a string of insulator strings consisting of at least four pieces of suspension insulators in the early stage of the rainy season of the measurement year, and it is generally considered to hang 6 pieces of suspension insulators. Suspension insulators generally choose standard type insulators, such as XP-7 insulators. Step 103: According to the local weather forecast, the expected start time of the dry season. Step 104: Collect and measure the dirt content W of the first insulator after removing the top and bottom insulators of the insulator string 1 . Insulator pollution is generally collected manually with a sampling cloth, which can measure salt density, dust density, or one of ...
