110kV户内变电站主变中性点设备全封闭绝缘方案研究
|
摘要
针对大城市110kV户内变电站用地紧张、建筑高度受限等现实情况,可选用110kV中性点全封闭设备。探讨了主变压器及高压中性点设备的耐压试验方案的可行性,主变压器中性点设备全封闭绝缘方案可节省占地面积、降低建筑物高度、提高环境适应性和增加设备运行可靠性,可供110kV紧凑型户内变电站的设计作参考。
According to the limited land area and building height of 110 kV indoor substation in the big city,it is proposed that the high-voltage side and the high-voltage neutral point of the main transformer adopt fully enclosed insulated outlets and select 110 kV neutral point fully enclosed apparatus.This paper discusses the feasibility of the withstand voltage test for the main transformer and high voltage neutral point apparatus.It is concluded that the fully enclosed insulation scheme of the main transformer neutral point device can save occupied space,reduce building height,improve environmental adaptability and increase equipment operation reliability.It can be used as a reference for the design of 110 kV compact type indoor substation.
