Abstract
Using quadrangle 8 - nodded isoparametric finite element analysis method
the electric field calcula-tions are made for different configurations of 330kV SF6 puffer arc - extinguishing chamber. The influences of the voltage - dividing capacitor
the shield of voltage - dividing capacitor and the shield of moving contact on electric field are dis-cussed by comparing the numerical calculation results.
