Electric Field Calculation for SF_6 High Voltage Circuit Breaker by Finite Volume Methods

摘要

In this paper, the finite volume method (FVM) for calculating axial symmetrical electric field distribution has been deduced. The surface integral of the mathematics model on all control volume of meshing elements is turned to boundary integral by Green formula. Thereby the discritized equation set of finite volume method for electric field calculation has been established. The electric field distribution of a 550 kV SF_6 circuit breaker has been calculated. The location and variation of E_(max) with the different stroke have been discussed.
