2. The test data of saturated salt density and ash density is an important basis for the distribution map of polluted areas.
3. Prevent pollution flashover of lines (electrical equipment) by dividing the pollution area distribution map of power system.
4. External insulation configuration principle: "configuration in place, leaving redundancy".
5. The ultimate goal is to use traditional insulators to complete the transition from clean area to moderately polluted area without cleaning the lines, and use composite insulators to realize the non-cleaning of lines in heavily polluted and heavily polluted areas.
6. Insulation in place: Rely on the insulation level of the equipment body to resist pollution flashover caused by harsh natural environment, and the insulation design is not based on large-scale cleaning work (once a year); Reduce operation and maintenance costs by reducing manpower, material resources and financial resources.
Wuhan CommScope Evergreen is a professional online monitoring system for salt density of transmission lines. The device uses optical sensing technology to monitor the salt density and ash density of insulators in real time, which provides scientific basis for drawing the distribution map of polluted areas and preventing and reducing pollution flashover accidents.
