1.Except normal functional wiring of protections during erection,the system voltage and load current should be used to check the correctness of inline polarity for protections after completion of erection and trial operation in order to find out wrong connection promptly and correct it.
除了在安装时能够实现保护装置正常功能的接线外 ,还应在安装竣工后保护装置投入系统试运行时 ,用系统电压和负荷电流校验接入保护装置接线极性的正确性 ,以便及时发现、纠正错误接线。收藏指正
2.D finite element local analysis is done for HV porcelain post insulator by ABAQUS finite element software.The stress distribution of one-piece structure under dead weight,erection deviation,temperature change,wind load and short-circuited load is analyzed,which provides the scientific basis for security assessment of post insulator.
以高压瓷瓶支柱绝缘子为研究对象,采用ABAQUS有限元软件进行三维有限元局部分析,分析了整体结构在自重、安装偏差、温度变化、风载以及短路电流载荷作用下的应力分布,为支柱绝缘子的安全性评定提供了科学的依据。收藏指正
3.Using the finite element software-ANSYS,numerical simulation analysis of the ultimate bearing capacity of reinforcing T-type RHS joints with combined load is studied,the stiffener methods are the erection of transverse or longitudinal ribbed stiffeners in the chord.
通过有限元软件ANSYS对加强T形方管节点在复合受力作用下的极限承载力进行了数值模拟分析,采用的加强方式为在主管内部设置横向和纵向加劲肋。收藏指正
