XGT9-12 switchgear is a three-phase AC air-insulated fixed indoor switchgear. It can be equipped with FT8 high-breaking indoor high-voltage AC vacuum load switch, FT8 high-breaking indoor high-voltage AC vacuum load switch-fuse combination electric appliance and VT28 indoors high-voltage AC vacuum circuit breaker is suitable for 12kV three-phase AC 50 HZ single bus system. It is used for receiving and distributing electric energy, it has the functions of controlling, protecting, monitoring the line. It can be widely used in the urban and rural distribution, secondary substation, new energy power stations, airports, railways, large buildings, factories and other places.

產品特點Product Features

1、小型化：C、F、V三種柜型的寬度尺寸全部為500mm；且開關高度方向尺寸小，對于柜高1800mm時電纜接線高度≥650mm；

2、一體化：負荷開關（斷路器）+隔離開關+接地開關+熔斷器一體式設計；

3、1250A隔離開關采用專利技術（實用新型專利，專利號：ZL201822267350.0），通流能力強，滿足國網1.1倍溫升要求；

4、母線室與電纜室采用金屬隔板隔開，滿足PM隔室要求，符合LSC2類開關柜的要求；

5、負荷開關、斷路器外形與尺寸一致，方便配柜，便于開關柜的擴展和組合；

6、隔離開關分閘狀態時，隔離刀對地距離仍大于125mm；

7、完善的“五防”聯鎖裝置，操作機構和“五防”聯鎖機構集成在操動機構箱內，采用互鎖式設計，防誤操作直觀可靠；

8、開關裝在柜內后仍可進行機械特性測試；

9、負荷開關（或斷路器）的每一相所有帶電零部件均由單個絕緣套管支撐，結構緊湊；

10、開關可以倒裝，開關柜可靠墻安裝。

1. Miniaturization: The dimensions for C、F、V type switchgear are 500mm and the dimensions of switch height is small, the cable wiring height is not less than 650mm while #he switchgear height is 1800mm;

2. Integration: The intergration design of the load switch (circuit breaker), the disconnector, the earthing switch and the fuse;

3.The 1250A disconnector adopts patent technology（Utility model patent ，Patent number：ZL201822267350.0）, the current carrying ability is strong, which is applicable for the 110% temperature rise requirement of state grid;

4.Adopt metal partitions to divide the bus compartment and cable compartment, which meets the requirement of PM compartments and LSC2 Type switchgear;

5.The appearance and dimensions of load switch and circuit breaker are exactly the same, which is convenient for installation of switchgear, and facilitates the expansion and combination of the switchgears;

6.When the disconnector is in opening status, the distance between the disconnecting knife and the ground is still more than 125mm;

7. The perfect "five prevention" interlock device, the operating mechanism and the “five prevention" interlock mechanism are integrated in the operating mechanism box. The box adopts interlock design, which may prevent misoperation directly and reliably;

8. The switch may still be carried out mechanical characteristic test after it is installed in the switchgear;

9. All the live parts of every phase of the load switch (or the circuit breaker) are supported by the single insulator bushing with compact structure;

10.The switch may be inverted to install. The switchgear may be installed against the wall.
