| 摘 要： | 由于新型旋气喷口在喷口上游引入旋气槽，使灭弧室内部电场分布发生变化.采用有限元法，分析了旋气喷口对灭弧室电场造成的影响.通过改变旋气喷口的结构参数，如旋气槽的数量及偏转角度，对比得到了无槽结构和不同旋气喷口断路器在开断过程中，灭弧室内的最大电场强度变化及旋气槽内电场的变化规律.三维电场计算结果表明，新型旋气喷口绝缘性能良好，对灭弧室内部电场影响较小，从电场角度充分证明了旋气喷口的可行性.

| Abstract: | The establishment!of rotary-gas grooves in the upstream area of nozzle will change the distribution of electric field in arc-quenching chamber. Thus,the influence of the rotary-gas nozzle on the electric field of arc-quenching chamber was analyzed using finite element method. Through changing the structural parameters of rotary-gas nozzle,such as quantity and angel of rotary-gas grooves,the maximum electric field strength variation in arc-quenching chamber and the electric field distribution in the rotary-g... |
