Description

technical field [0001] The invention belongs to the technical field of electrical equipment insulation structure design, and in particular relates to a method for optimizing the electrical performance of a GIL three-pillar insulator based on a particle swarm algorithm. Background technique [0002] The three-post insulator is a key component of the Gas-insulated Metal-enclosed Transmission Line (GIL). It plays the role of supporting conductor and electrical insulation in the GIL. Its structural design needs to fully consider the electrical performance of its different parts. , so as to avoid the occurrence of insulation failure. At present, the design of three-pillar insulators is mainly based on computer numerical calculation methods to optimize the electrical performance of a certain position of the three-pillar insulator. When the electrical performance of a certain part of the three-pillar insulator is improved, the performance of other parts will often be reduced. It h...
