摘要
根据某型号35 kV充气式开关柜的双气箱(母线充气隔室和断路器充气隔室)结构,分析了充气式开关柜在使用与检修过程中发生漏气故障的主要原因,提出了提高气箱结构强度,降低其核心部位变形量的处理方法;再利用SolidWorks软件设计出该某型号充气式开关柜的虚拟样机三维模型,并结合实际工况对三维模型进行修正和简化,又通过计算加强筋的截面惯性矩来分析加强筋的设计对气箱结构强度的影响,继而借助ANSYS Workbench模拟分析软件对该型号充气式开关柜的核心零部件进行有限元分析,获得气箱核心部位变形量的数据及不同加强筋布置方式的变化规律;优化了气箱结构,减小了充气之后气箱的变形量,且使充气式开关柜气箱各个部位的局部应力在材料许用范围内,保证了该型号产品的生产的连续性和运行的稳定性,为处理同类故障提供参考。
According to the structure of the double air box(busbar inflatable compartment and circuit breaker inflatable compartment)of a certain type of 35 kV inflatable switchgear of our company,the main reasons for the air leakage fault during the use and maintenance of the inflatable switchgear were analyzed,and the processing method was proposed to improve the structural strength of the air box and reduce the deformation of its core parts.The SolidWorks software was used to design a virtual prototype three-dimensional model of a certain type of inflatable switchgear,and the three-dimensional model was modified and simplified according to the actual working conditions.The moment of inertia of the section of the stiffener was calculated to analyze the influence of the stiffener design on the structural strength of the air box,and then the ANSYS Workbench simulation analysis software was used to perform finite element analysis on the core components of the type of inflatable switchgear to obtain the deformation of the core part of the gas box.The data of the quantity and the change law of the arrangement of different reinforcing ribs and the structure of the air box was optimized.The deformation of the air box after inflation was reduced,and the local stress of each part of the air box of the inflatable switchgear was within the allowable range of materials.It ensures the continuity of production and the stability of operation of the type of product,and provides a reference for dealing with similar faults.
