摘要 为解决大电流管母支撑金具温升过高的问题,依托某换流站融冰工程,采用电磁-热力学耦合仿真与试验相结合的方法,研究管母支撑金具的损耗及温升特性,分析金具结构及材料属性与温升之间的数值关系。研究结果表明,金具导磁性较好且距离导体较近时,采用开槽处理并不能彻底解决局部温升过高的问题;采用磁导率较低且电导率较高的材料,可有效抑制涡流损耗,避免局部温升过高。现场试验结果与仿真计算结果基本吻合,验证了仿真模型的合理性及准确性。

Abstract：In order to solve the excessive temperature problem of the tubular busbar support fittings, for a convertor station ice-melting project, the tubular busbar support fitting loss and temperature characteristic are studied by electromagnetic-thermal coupling method and test. Based on the simulation data, the impact of the fitting structure and material property on the temperature is analyzed. The results show that, if the fitting is with high permeability and is close to the conductor, slotting cannot suppress the temperature rise thoroughly. Low permeability and high conductivity material can reduce the loss significantly, thus to avoid the excessive temperature rise. The test results basically coincide with the simulation, and it verified the rationality of the simulation model.
