摘要
介绍了在低压配电系统中,如何通过国际标准IEC 60865-1和IEC/TS 60865-2中给出的方法来计算配电柜中矩形水平母线的动热稳定。通过对实例的计算结果,验证了导体选择排列及绝缘支撑件安装布局方式等方面的合理性。
This article introduced the methods on how to calculate the dynamic and thermal stability of the rectanguler horizontal busbar in distribution board according to IEC 60865- 1 and IEC / TS 60865- 2 in low voltage distribution systems. The article also verified the rationality of the selection and alignment of conductors and the arrangement of insulating supports by the calculation results of the examples.
