Embodiment Construction
[0025] The configuration method of the high-voltage transmission line insulator proposed by the present invention, its flow chart is as follows figure 1 shown, including the following steps:
[0026] (1) Establish the first mapping table between the pollution level and the creepage ratio distance, and the second mapping table between the voltage level and the insulator string length threshold, the mechanical strength range of the insulator, and the recommended insulator string type;
[0027] (2) According to the pollution level of the high-voltage line to be designed, look up the creepage ratio distance from the first mapping table above, and calculate the string length L of the insulator to be selected according to the creepage ratio distance and the voltage level of the high-voltage line to be designed 0 , according to the voltage level of the high-voltage line to be designed, look up the insulator string length threshold from the above-mentioned second mapping table, and se...
