摘要
文章分析了大电流开关柜与小电流开关柜设计上的差异,指出了在大电流成套开关设备设计过程中,对母线和绝缘子的选型应进行短路电流动稳定和热稳定校验。提出了设计时为降低发热应采取的措施。
This paper analyses the difference between the high current switchgear and the low current switchgear, and point out that in process of designing the high current complete switchgear, it＇s necessary to verify the short circuit dynamic stability and the thermal stability of the selection of the busbar and insulator. The design measures for reducing heat generation are also introducted.
