| 摘 要： | 采用暂态电路模型对真空断路器开断空载变压器时由复燃和截流引起的过电压进行了数值模拟，并对暂态过电压的频率成分进行了离散的傅立叶分析，以此作为真空断路器的边界夺件，采用有限元法进行了计算，给出了灭弧室内的暂态电场分布和电场强度随时间变化的曲线，讨论了暂态电场的一些特征，为真空断路器的绝缘设计提供了参考. |

| Abstract: | Simulates the over- voltage of vacuum circuit breaker which caused by reignition and current chopping using transient circuit model, analyzes the frequency components of transient over- voltage by discrete Fourier analysis. Taking it as boundary condition, calculates the electric field of vacuum circuit breaker by finite element method, gives the curves of transient electric field distribution of vacuum cricuit breaker and current intensity which charge with time. Discusses some characteristics of transient electric field, provides reference for insulation design of vacuum circuit breaker. |
| Keywords: | transient circuit model interrupter chamber transient field finite element method |
