Abstract:Hybrid circuit breaker (HCB) based on the series of vacuum interrupter and SF6 interrupter uses strong interruption capacity of vacuum and the linear insulation property of SF6 gas to be a high-voltage and high-current breaker. The numerical calculation of 3D electric field is an important way to analyze reasonable and optimization of its structure. The 3D model of the vacuum interrupter and SF6 interrupter are established; the internal electric field distribution of vacuum interrupter and SF6 interrupter are calculated by Ansoft software, and their self-capacitances are solved. Then a 3D computational model of HCB based on models of vacuum interrupter and SF6 interrupter is established, and the distribution characteristics of its electric field are analyzed. The simulation result of electric field distribution of HCB is obtained, and the structure of HCB is optimized designed. It provides a theoretical basis for the structural design of the experimental prototype of HCB.
