摘要
强迫风冷系统的风机及电机的选择与封闭母线的额定电流、导体的截面尺寸、母线运行过程中的发热量以及母线的布置走向等有着密切的关系。在正常条件下,强迫风冷装置是必须长期投入运行的,而强迫风冷系统配置的风机电机功率较大,运行过程中将产生大量电能损耗,本文将重点描述强迫风冷系统加装变频风机后在满足各工况条件需求、节能降耗及保护母线稳定等方面的优势。
The model selection of the of the forced cooling system for IPB depend on the IPB rated current, conductor cross section, loss during operation and the IPB arrangement .Under the normal condition , the forced cooling system should be put into operation, but the power of the motor normally is big, so it will have a lot of energy loss during operation .This article mainly describes the forced cooling system can satisfied all kind of the working condition and the advantage in saving energy and reducing consumption.
