Insulator string dirt accumulation correction method

Abstract

The invention provides an insulator string dirt accumulation correction method, which comprises the following steps: acquiring environmental parameters of a target power transmission line, and determining 50% probability distribution value of each environmental parameter in unit time based on the environmental parameters; determining a surface dirt particle collision coefficient of the suspension string insulator and the V-shaped string insulator based on the environmental parameters; determining the ratio of the collision coefficients of the dirt particles on the surfaces of the suspension string insulator and the V-shaped string insulator; and determining the pollution grade target value of the V-shaped string insulator based on the pollution grade target value of the suspension string insulator. Through the method, the pollution particle concentration, the particle size, the wind speed atmospheric parameter and the 50% probability distribution value in unit time of the target power transmission line area are considered; the design pollution grade target value of the V-shaped insulator serving as a transformation target is accurately determined on the basis of the suspension string insulator, string type transformation can be carried out on the insulator string of the target power transmission line, antifouling work is accurately guided to be carried out, and safe and stable operation of a power grid is ensured.

Description

technical field [0001] The invention relates to a correction method, in particular to a correction method for insulator series contamination. Background technique [0002] With the rapid growth of urban and rural economy, my country's air pollution is becoming more and more serious. The relocation of heavily polluting factories from the city center to the suburbs and the emergence of a large number of township and village enterprises that use coal as their main energy source, and the increase in the height of factory chimneys, all of which have rapidly expanded the area affected by industrial pollution; the rapid development of road construction, the substantial increase in traffic flow, and the dense road network All lead to the aggravation of motor vehicle exhaust emission pollution. my country is in a period of rapid economic development, and the current energy is still dominated by coal. Therefore, it is difficult to effectively improve the atmospheric environment in a ...

AI Technical Summary

Problems solved by technology

my country is in a period of rapid economic development, and the current energy is still dominated by coal. Therefore, it is difficult to effectively improve the atmospheric environment in a long period of time (except for key cities), and air pollution will threaten the safe operation of the power grid for a long time
