摘　　要：近年来,气体绝缘全封闭组合电器(Gas insulated substation,GIS)在我国得到了迅速地推广与应用,盆式绝缘子在其中通常起着重要作用,它的质量好坏,影响到整个系统的可靠运行。环氧树脂复合材料常被用于制备盆式绝缘子,需要在高温下进行固化反应。在固化过程中温度场的不均匀分布,会导致盆式绝缘子内部产生缺陷。通过计算机仿真技术,运用有限元原理对盆式绝缘子在固化成型的整个过程进行仿真计算,分析了固化过程中的绝缘子温度场分布情况。最后,通过对盆式绝缘子的固化成型过程进行试验,验证了仿真模型的正确性。In recent years,gas-insulated fully enclosed combined electrical appliances(GIS)have been rapidly promoted and applied in China.Basin insulators usually play an important role in it,and its quality affects the reliable operation of the entire system.Epoxy resin composites are often used to prepare pot insulators and require a curing reaction at elevated temperatures.Uneven distribution of the temperature field during the curing process can cause defects inside the basin insulator.Through the computer simulation technology,the finite element principle is used to simulate the whole process of the pot insulator in the curing process,and the temperature field distribution of the insulator during the curing process is analyzed.Finally,the correctness of the simulation model is verified by experiments on the solidification molding process of the basin insulator.
