功率柜节能散热系统
本专利技术涉及应用于电力系统中的无功补偿装置(SVG;英文StaticVarGenerater的缩写),尤其是涉及功率柜节能散热系统。
技术介绍
无功补偿装置广泛应用于远距离电力传输、城市二级变电站、电弧炉、轧机和提升机、区域电网、光伏发电、风电场、电力机车供电等工程领域。我国南水北调中线总干渠河南段、河北段设35kV供电系统专网,输电线路长度约1100km,由35kV线路、中心开关站、沿线负荷点降压变电站组成,电源引自沿线地方电网110~220kV变电站中的35kV母线,沿线路共设置13个35kV中心开关站,每个中心开关站从所在地区的电力系统中引1至2回路35kV电源,由中心开关站引出2回路35kV线路分别向干渠上游、下游两侧辐射供电,在干渠负荷点处设35kV/0.4kV降压变电站向负荷点供电,沿线负荷点降压变电站309座。为保证南水北调中线总干渠35kV供电系统的供电质量,在35kV中心开关站和负荷点降压变电站等位置设置无功补偿装置。目前,市售的无功补偿装置中的功率柜为整机箱体成套结构,整机箱体内部包含若干个独立的实现不同功能的功率元件模块 ...
