Abstract
Under the long-term influence of electrical load and natural environmental factors, the insulation performance of the insulator will gradually decrease, and deteriorated insulators with different degrees of deterioration will appear in the insulator string. The presence of degraded insulators can pose a significant risk to the safe operation of the power system. In order to study the influence of insulators with different degradation degrees on the voltage distribution of insulator strings in 500 kV transmission lines, this paper studies the distribution voltages of different positions, different numbers and different degraded insulators in 500 kV transmission line insulator strings based on finite element method. The simulation results show that the voltage drop of the insulator with a lighter degree of degradation is very low, and it is more difficult to identify by the distributed voltage. The deteriorated insulator has a certain lifting effect on the voltage of its adjacent insulator. Finally, the effects of different degrees of deteriorated insulators on the voltage distribution are studied by experiments. The conclusions are consistent with the simulation results.
