Abstract: This paper analyzed the impact of each component part in 1 100 kV gas insulated double shielding composite bushing on electrical properties of the composite bushing, established the mathematical model and used the software ANSYS to carry out calculation and optimization for composite bushing electric field distribution. The optimization result shows that under the thunder and lightning impulse voltage, each part of potential distribution was well-distributed and the interior of bushing and the surface of field intensity of insulators met the theoretical requirements with enough overmeasure. This product has passed the whole type test and fulfilled the engineering requirement of each technical specification.
Key words: 1 100 kV gas insulated double shielding composite bushing; internal field intensity; potential distribution; optimum design
