Effects of Shielding Rings on the Electric Field Distributions of Composite Insulator
Mathematical model of composite insulator is set up
and electric field distribution along the surface is calculated.Based on finite element method
electric field distribution of 220 kV composite insulators
without shielding ring or with different size shielding rings
is analyzed.Then the effects of different structural parameters and shape on electric field intensity and potential distribution of composite insulator are analyzed.At last
some advices on the structural parameters of shielding ring are given.
