Abstract:

设计了一种分相式快速真空断路器,主要由混合式快速机构和固封极柱构成,混合式快速机构包括永磁机构和双线圈斥力机构2部分。利用AnsysMaxwell对快速机构进行了建模和有限元分析及其优化;并考虑实际产品中斥力机构的整体结构布局,对斥力部分线圈骨架材料及结构形式、有无斥力外壳支架进行了针对性的仿真优化。在仿真的基础上,研制了10kV快速真空断路器的实验样机,并通过大量的实验验证了仿真的正确性。针对因快速机构合闸速度快导致的合闸弹跳大的问题,采用了液压缓冲装置及对其合理的结构设计来解决。最终实测其分闸时间为2.1ms,分闸反弹小于2mm,合闸时间为9.6ms,合闸弹跳小于1ms,满足国标规定和项目要求。样机在中国电科院试验站通过了包括短路关合和开断试验、机械试验、温升试验及动热稳定试验在内的多项型式试验。
