12kV户外真空断路器电场数值计算与分析
摘要
采用有限元法对 3种结构真空断路器灭弧室的电场进行了计算分析
计算中考虑了悬浮电极、瓷外绝缘以及硅橡胶外绝缘对电场分布的影响
其结果为户外真空断路器外绝缘的优化设计提供了理论基础
Abstract
Taking into account the different effects of porcelain insulation casing
the silicon rubber external insulation and floating shield on the electric field
the relevant electric fields have been calculated for three kinds of vacuum circuit breakers using finite element method(FEM). The theoretical basis for further optimization design of external insulation and the development of outdoor vacuum circuit breaker is provided.
