摘要:
为了准确计算GIS的温升,探究了载流导体邻近与趋肤效应及电流频率对三相共箱式 GIS温升的影响。将弹簧触指和梅花触指均简化为圆环体来模拟电接触。采用三维多物理场耦 合的方法,计算并对比了考虑与不考虑载流导体邻近与趋肤效应时的GIS的欧姆损耗和温度分 布,比较了不同频率对GIS温升的影响。搭建温升试验平台验证了仿真结果的正确性。结果表 明,三相共箱式GIS载流导体的邻近与趋肤效应所产生的的附加损耗较大,其影响不可忽略; 相比于不考虑邻近与趋肤效应的计算结果,考虑载流导体邻近与趋肤效应下的温升结果与实验 结果吻合较好;在60 Hz条件下GIS的温升相对于50 Hz普遍有所升高但差别不大。
Abstract:
In order to calculate the temperature-rise of GIS accurately, the influence of proximity and skin effect of current carrying conductor and current frequency on the temperature-rise of three-phase-in-one-tank type GIS is discussed. The structure of spring contacts and plum contacts is properly simplified to simulate the electrical contact. Using three-dimensional multi- physics coupling method, the ohmic losses and temperature distribution of GIS with/without considering proximity and skin effect are calculated and analyzed, respectively. And the effects of different frequencies on the temperature-rise of GIS are compared. A temperature-rise test platform is built to verify the simulation results. It is found that the additional losses caused by the proximity and skin effect cannot be ignored. Compared to the calculated results without considering the proximity and skin effects, the temperature-rise results are closer to the experiment results when considering the proximity and skin effects. The calculated temperature-rise of GIS at 60 Hz is a little higher than the temperature-rise at 50 Hz.
