摘要:
利用COMSOL 51软件建立真空断路器三维有限元模型,通过加载交流耐受电压分析和计算12 kV真空断路器隔室和灭弧室的电场分布以及动静触头在不同开距下的电场强度变化规律。通过仿真与优化可知:真空断路器灭弧室内屏蔽罩和陶瓷套管起到改善电场强度分布的作用;真空灭弧室4个场强较大值部位的圆角半径取25 mm较为合适;断路器分闸时,真空灭弧室动静触头之间的开距应取8~11 mm。仿真结果为真空断路器小型化和绝缘性能优化设计提供参考。
Abstract:
In order to analyze electric field distributions of 12 kV vacuum arc extinguish chamber on the breaker cabinet and arc chamber,threedimension finite element method model of vacuum circuit breaker was established by using COMSOL51.Numerical simulations of electric field on the circuit breaker chamber and vacuum arcing chamber and the maximum electric field intensity was compared with electric field intensity of air breakdown to test the insulation reliability of circuit breaker.Conclusions are obtained that shield and porcelain bushing of vacuum arcing chamber are used to change the values of electric field intensity.Meanwhile,the fillet radius of 4 kinds of maximum electric field intensity is 25 mm on the vacuum arcing chamber.When circuit breaker opens,the opening distance between dynamic contactor and static contactor of vacuum arcing chamber ranged from 8 to 11 mm.The conclusions of simulation about the space distribution,location and values of electric field intensity satisfies the insulating property and the requirement of miniaturization design.
