摘要

基于真空断路和SF6断路系列的混合断路器(HCB)，利用了真空的强断路能力和SF6气体的线性绝缘特性，是一种高压大电流断路器。三维电场的数值计算是分析其结构合理和优化的重要途径。建立了真空灭流器和SF6灭流器的三维模型;利用Ansoft软件计算了真空灭流器和SF6灭流器的内部电场分布，并求解了它们的自容。在真空灭弧器和SF6灭弧器模型的基础上，建立了HCB的三维计算模型，分析了其电场分布特性。得到了HCB的电场分布仿真结果，并对HCB的结构进行了优化设计。为HCB实验样机的结构设计提供了理论依据。

Static electric field distribution of hybrid circuit breaker based on Ansoft

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.
