火力发电厂高位布置封闭母线垂直段导体温升的研究

Research on Conductor Temperature Rise in Vertical Section of Closed Busbars in High Position in Thermal Power Plants

火电厂汽轮发电机组高位布置,发电机出口离相封闭母线布置为长垂直段型式;在高位布置下大电流、高垂直布置方式的基础上,对离相封闭母线导体的温升、散热、烟囱效应等进行了数据分析及计算研究,通过计算结果和数据比较,提出了离相封闭母线的导体及外壳选型建议。

The thermal power plant steam turbine generator set is arranged at a high position,and the out-of-phase closed busbar at the generator outlet is arranged in a long vertical section.Data analysis and calculation research were carried out on heat dissipation,chimney effect,etc.By comparing the calculation results and data,it is recommended to select the conductor and shell of the isolated-phase closed busbar.
