| 摘 要： | 藏北高原那曲３５ｋＶ变电站地处海拔高程４６００ｍ，具有典型的高原地理和气象特征，国产高原型电气设备外绝缘水平已不能满足该变电站绝缘配合的要求。为此，其中一部分电气设备选用了提高一个电压等级的产品，另外还研制的适用于海拔５０００ｍ的ＧＧ－１Ａ（Ｆ２）Ｇ型开关柜。为高原型高压开关柜增添了一个新品种。

| Abstract: | kV transformer station is located at elevation 4 600m at Laqu in northern Tibet Plateau. It is characterized by plateau geography and climate. Grade of external insulation of electrical equipment especially for plateau made in China can not meet the requirements.Therefore,higher grade electrical equipment are selected for some places.Besides,GG-1A(F2) swicth cabinet is developed to be suitable at elevation 5 000m.It is a new product of high voltage swicth cabinets for plateau. |
