摘要:
机械特性是高压开关重要的设计参数,尤其是利用单一转轴进行三相驱动的结构形式。文中以FLN36型负荷开关转轴为研究对象,对其材质、结构进行优化,通过有限元仿真分析、相应试验校核,最终将转轴材质定义为30%GF含量(质量分数)的PC工程塑料,壁厚为2 mm,强化转轴强度和刚度,减小开关三相分合闸不同期,改善机械特性,提高了开关的安全可靠性,为同类产品的设计优化提供了参考。
Abstract:
Mechanical characteristics of high-voltage switch are important design parameters for high-voltage switches, particularly for the type with single shaft driving three phases. This paper researches the rotating shaft of FLN36 switch in respect of material reinforcement and modification. Finite element analysis and corresponding experimental verification are conducted. As a result, the engineering plastics PC with 30% of GF is selected as the material for the shaft , and the wall thickness is determined to be 2 mm. Thus the strength and stiffness of the shaft are strengthened, the out-of-sync of three-phase switching is reduced, the mechanical characteristics are improved, and the reliability of the switch is greatly improved.
