Abstract
The invention relates to a method, a system and a device for measuring and calculating the external insulation pollution degree of an electric transmission and transformation device, wherein a spot pollutant accumulation measuring device automatically measures the electrical conductivity of pollutants by utilizing a conduction electrode on the surface of a simulation shed, data is transmitted into a central server for measuring and calculating the pollution degree and is converted into the equivalent salt density, the accumulation amount of external insulation pollutants before and after each rainfall can be measured immediately, and the accumulation amount on the external insulation surface pollutants at a measuring site is predicted according to the pollutant accumulation velocity so as to early warn the pollution flashover risk of the device.
