在硬梁包水电站地面GIS室内，水电五局机电安装团队与厂家技术人员正严谨而高效地进行设备安装作业。

500千伏GIS高压设备是硬梁包水电站电能送出的重要设备，地面500千伏GIS采用户内布置，母线采用3/2接线形式，断路器水平布置，主母线布置在断路器两侧，共设置10个断路器间隔和4组进线电缆终端及2组出线套管，设有1回出线至甘谷地变电站。

预计将在6月底前完成全部GIS设备的安装工作，届时将达到进行特殊试验的标准，为500千伏高压电缆安装、主变倒送电及全厂厂用电的形成提供了基础条件。

In the GIS room of the hard beam Bao hydropower Station, the electromechanical installation team of the fifth Hydropower Bureau and the technicians of the manufacturer are strictly and efficiently installing the equipment.

500 kV GIS high voltage equipment is an important equipment for sending electric energy out of hard-beam hydropower station. The ground 500 kV GIS adopts indoor layout, the bus bar adopts 3/2 connection form, the circuit breaker is arranged horizontally, the main bus is arranged on both sides of the circuit breaker, a total of 10 circuit breaker intervals, 4 groups of incoming cable terminals and 2 groups of outlet bushings are set, and 1 return outlet line is provided to the Gangudi substation.

It is expected that the installation of all GIS equipment will be completed by the end of June, and the standard for special tests will be reached by then, providing the basic conditions for the installation of 500 kV high-voltage cables, the reverse power supply of the main transformer and the formation of the power supply of the whole plant.
