絕緣子飽和受潮條件下泄漏電流預(yù)測(cè)方法
[Abstract]:In order to realize the on-line monitoring and warning of contamination degree by measuring the leakage current on the insulator surface, the factors affecting the leakage current under saturated damp condition are studied. In this paper, a method of controlling environmental humidity in large space laboratory is proposed. The leakage current on the surface of insulator is studied under different humidity conditions, and the equivalent salt density is analyzed. The influence of environmental humidity on the trend of leakage current is discussed, and the relationship between leakage current of insulator under different humidity is discussed. The results show that the leakage current is closely related to the dampening process of the insulator, and the linear conversion relationship between the leakage current measured under low humidity and the saturated damped current can be approximately considered under the condition of no temperature difference. Furthermore, the method of predicting the leakage current under saturated damp by using the leakage current under low humidity is presented, and its application range is discussed.
