SF_6旋弧灭弧室设计中的几个主要问题

Main Problems on Design of SF6 Rotating Arc Chamber

本文论述SF_6旋弧灭弧室设计中应注意的几个主要问题,提出了解决这些问题的办法。文中就Ι、ψ间的相差θ为什么存在最佳区域作了分析,但同时认为θ的取值不必作为首要设计参数来考虑。

Main problems on design of rotary arc chamber of SF, circuit breaker are discussed and solved in this paper. We recognize that properly designed magnetic construction can accelerate arc transition, avoid re-arcing, and central the roots of arc to be rotated with same angular speed to raised the interruption capacity; the phase difference between current and magnetic linkage is not a prime factor to be considered, though its value must be selected within an optimal range from 30° to 60°
