适用范围Application Range

XGT9开关柜是三相交流空气绝缘的固定式户内开关设备,可内配FT8高分断户内高压交流真空负荷开关、FT8高分断户内高压交流真空负荷开关-熔断器组合电器和VT28户内高压交流真空断路器,适用于12kV三相交流50Hz单母线系统,作为接受和分配电能之用,具备对线路进行控制、保护、监视等功能,可广泛应用于城乡配电、二次变电站、新能源电站及机场、地铁、大型建筑、工厂企业等场所。

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.

产品特点Product Features

1、小型化:C、F、V三种柜型的宽度尺寸全部为500mm;且开关高度方向尺寸小,对于柜高1800mm时电缆接线高度≥650mm;

2、一体化:负荷开关(断路器)+隔离开关+接地开关+熔断器一体式设计;

3、1250A隔离开关采用专利技术,通流能力强,满足国网1.1倍温升要求;

4、母线室与电缆室采用金属隔板隔开,满足PM隔室要求,符合LSC2类开关柜的要求;

5、负荷开关、断路器外形与尺寸一致,方便配柜,便于开关柜的扩展和组合;

6、隔离开关分闸状态时,隔离刀对地距离仍大于125mm;

7、完善的“五防”联锁装置,操作机构和“五防”联锁机构集成在操动机构箱内,采用互锁式设计,防误操作直观可靠;

8、开关装在柜内后仍可进行机械特性测试;

9、负荷开关(或断路器)的每一相所有带电零部件均由单个绝缘套管支撑,结构紧凑;

10、开关可以倒装,开关柜可靠墙安装。

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, 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.
