摘要
对高压电器整体式电触头灭弧端和导电端复合面型式进行了分析,台阶式复合面面积要比平接式复合面面积大一倍以上,采用台阶式复合面可提高灭弧端和导电端的复合强度。应用ANSYS/LS-DYNA软件对触头插入过程进行三维大变形有限单元数值模拟,对电触头在插入过程中的应力和变形进行了分析,证明动弧触头台阶式复合面满足强度要求。
The compound surface pattern between arc-extinction and conduction ends of integral type electric contact in high-voltage electrical apparatus is analyzed. The result shows that the area of stepped compound surface is twice of flush compound surface, hence the stepped compound surface can enhance the combination strength between arc-extinction and conduction ends. The 3D elastic-plastic deformation in inserting process of the contact is simulated by using the ANSYS-LS/ DYNA software to analyze the stress and deformation of the contact during inserting process and to prove that the stepped compound surface for dynamic are meets the strength requirement.
