摘要
均压环是高压电器设备的重要组成部分,其主要作用是均衡对地杂散电容,使电压分布均匀。运行在大风地区的高压隔离开关均压环,在风载荷的较大作用力下,其自身的设计强度和运行可靠性至关重要。基于ANSYS Workbench18.1有限元分析软件,对由于大风作用力引起的均压环断裂问题进行逐步分析,通过确定计算条件、进行受力分析、建立模型和仿真计算等,分析得出该均压环在较大的风载荷作用力下的位移和应力情况。结果表明,在保证均压环的设计强度满足使用要求的情况下,均压环的制造质量是影响其强度和运行可靠性的主要因素。给出了提高高压隔离开关均压环强度及运行可靠性的具体措施。
The grading ring is an important part of the high voltage electrical equipment. It is mainly used for balancing the stray capacitance and distributing the voltage evenly. Under a large force of wind load, the HV switch disconnector grading ring operating in high winds area is very important for its own design strength and operational reliability. Based on the ANSYS Workbench18. 1 finite element analysis software, a fracture problem of the HV switch disconnector grading ring caused by strong wind force is analyzed. The calculation condition determination, the stress analysis, the model establish ment, the stress surface cutting and the simulation calculation are carried out in step. The displacement and stress of the HV switch disconnector grading ring unde wind load are obtained. The results show that the manufacturing quality of the grading ring is the main factor affecting the strength and reliability of the grading ring when the design strength of the grad ing ring meets the requirements of operation. Some measures to improve the strength and reliability of the HV switch dis connector grading ring are put forward.
