1000千伏荆门扩建站施工具有与运行交叉多、接口多,气象环境与建设需求冲突,场地狭小,二次交流施工“高、精、险”并存等特点及难点。2011年11月21日17时44分,1000千伏荆门特高压变电站扩建区内2号主变传出轻微、持续的电流声,三台主变压器一次充电成功。随着当天深夜110千伏电容器组和电抗器相继完成投切试验,荆门站扩建工程新安装的电气设备全部通过带电检测,负责扩建施工的湖北省输变电工程公司施工人员在站门外的空地上燃放起喜庆的鞭炮。
The construction of 1000 kV Jingmen extension station has many characteristics and difficulties such as cross-operation, multi-interface, conflicting meteorological environment and construction requirements, small site size, secondary exchange construction, coexistence of high, fine and risk. November 17, 2011 17:44, 1000 kV Jingmen UHV substation extension area No. 2 of the main transformer heard a slight, continuous current sound, the three main transformer a successful charging. With the late-night 110 kV capacitor bank and reactor have completed the switching test, Jingmen station expansion project of newly installed electrical equipment through the live test, responsible for the expansion of construction in Hubei Province Transmission Engineering Company construction workers outside the station door Open space to set off festive fireworks.
