The proposed paper deals with the investigation of the electrical field distribution on an actual 36 kV gas insulated three phase load break switch application. The proposed medium voltage switch characteristics and applications are described and evaluated. In particular the switchgear characteristics and performances are focused. An accurate static analysis of the electrical field distribution in both the switchgear and the stainless steel tank will be carried out by several simulations on a suitable model through a finite element method (FEM). The numerical analysis is applied with two dimensional dedicated software tools. The simulation results allow the correct design of the distances for both the fixed and the rotary electrical contacts. The information on the electrical field distribution allows fitting the distances of the electrical contact and pressure value of the insulation gas (SF 6 ) injected in both the switchgear and the stainless steel tank.

Abstract
The proposed paper deals with the investigation of the electrical field distribution on an actual 36 kV gas insulated three phase load break switch application. The proposed medium voltage switch characteristics and applications are described and evaluated. In particular the switchgear characteristics and performances are focused. An accurate static analysis of the electrical field distribution in both the switchgear and the stainless steel tank will be carried out by several simulations on a suitable model through a finite element method (FEM). The numerical analysis is applied with two dimensional dedicated software tools. The simulation results allow the correct design of the distances for both the fixed and the rotary electrical contacts. The information on the electrical field distribution allows fitting the distances of the electrical contact and pressure value of the insulation gas (SF 6 ) injected in both the switchgear and the stainless steel tank.File | Dimensione | Formato | |
