Abstract

The three dimensional electric field of the end of the tank for type OFPTB-550 SF6 circuit breaker

was computed using the finite element method.For speciality of the structure in computing region

subdomain structure

isoparametric coordinates transformation

translation and rotation of coordinates

automatic decollating

and manual segmentation were combined organically in computing three dimensional electric field.A computing method of three dimensional electric field in a complicated structure has been presented.The computed results were processed graphically so that the computer simulation of the electric field distribution was achieved.The insulating strength of the circuit breaker was evaluated.
