Simulation analysis and calculation of electric field distribution characteristics of UHV wall bushing

Facing the unbalanced development of resource distribution and productivity, China needs long-distance power transmission and distribution. The long-distance power transmission will lead to a lot of power loss in the process of transmission. In order to achieve long-distance, large capacity, low los...

The long-distance power transmission will lead to a lot of power loss in the process of transmission. In order to achieve long-distance, large capacity, low loss power transmission, it is necessary to build UHV transmission and transformation lines in the power grid for cross regional power allocation. As the key equipment in UHV transmission and transformation, UHV bushing plays a very important role in UHV transmission and transformation line. However, due to working in UHV electric field for a long time, the reduction of UHV bushing failure rate is very important for the smooth operation of UHV transmission line.
