基于APDL与GUI动态电场计算方法研究

摘要
开断容性电流是高压断路器一项重要而且严格考核的试验项目。由于容性开断电流非常小,灭弧室内气流状态对开断过程影响较小,开断过程可近似为空载开断。此时断路器性能主要决定于灭弧室的动态电场分布,因此计算断路器在开断容性小电流时的动态电场分布有很大的工程意义。文中结合断路器灭弧室结构特点,提出了基于APDL参数化编程为主、GUI为辅进行断路器开断容性小电流过程中动态电场的计算方法。通过研究动态电场计算数学模型、动态数据模型及电场最大值的动态提取及曲线绘制等关键技术,实现断路器灭弧室的动态电场计算和绘制关键零件电场最大值的变化曲线。通过一种典型瓷柱式断路器的灭弧室动态电场计算,获得关键零件电场最大值并绘制变化曲线,以此判断动态电场分布是否满足设计要求。该方法效率高、通用性强,对开断容性小电流的断路器设计和研发具有指导意义。
It is very import and severe test to switch the capacitive current for circuit breaker. Flow condition of thegas in arcing extinguishing chamber is little influence on the switching current because the capacitive switching cur-rent is too low,and the switching process can be approximately no-load condition. Therefore,it is of great engineer-ing significance to calculate the dynamic electric field distribution of circuit breakers when switching capacitivesmall current. Combining the construction characteristics of the circuit-breaker,the method has been given that dy-namic electric field of arcing extinguishing chamber,in the switching process the capacitive switching current,issimulated by APDL and GUI. The key technology,including simulation model for dynamic electric field,dynamicdatum model,max values fetch of electric field intensity for key parts,and plotting curve by APDL and GUI,are re-searched. By these key technologies,it can complete dynamic electric field simulation and get the tendency of themax values of electric field intensity for key parts. Finally,there is a typical live tank circuit-breaker,as an exam-ple,by the method,it has completed dynamic electric field simulation and plotted the curve of the changes of elec-tric field intensity for every key parts,and then it can be used to judge if it is requirement of design. This method hashigh efficiency and universal property;it can guide the design for high voltage circuit-breaker,especially for the cir-cuit-breaker which need switch the capacitive switching current.
