【 摘 要 】

Optimal scheme of installing booster sheds for 35kV ceramic insulators was analyzed relating to the performance under power frequency voltage through finite element simulation. The simulation model was established in COMSOL to calculate and analyze the electric field on the surface of the insulator, installing different number of booster sheds and at positions. It is revealed that considering both the economic cost and technical performance, the monolithic installation of booster shed on the second layer of insulator is optimal scheme to meditate flashover.
