摘要
高压SF_6断路器保障着电力系统的安全稳定运行,研究其开断性能的仿真方法对于缩短产品上市周期、降低研发成本、实现性能优化具有重要意义。为此从SF_6电弧等离子体的基本属性、建模仿真以及弧后击穿计算三个方面综述了该领域的研究进展,并论述了基于电弧磁流体动力学建模的开断性能仿真技术在典型工程实践中的应用,为进一步开展相关研究提供参考。
The high voltage SF 6 circuit breaker can ensure safe and stable operation of the power system, thus it is important to study the simulation method for its interruption performance so as to shorten the cycle of coming into the market of products, reduce research and development costs and realize performance optimization. Therefore, this paper summarizes research development of this field in three aspects including basic attribute of SF 6 arc plasma, modeling simulation and post-arc calculation. It also discusses application of the simulation technology for interruption performance based on arc magnetic fluid dynamics modeling in typical engineering practices, which may provide references for further research.
