ABB型号名称:-

单位电容器组的单位通常称为电容器单元。电容器单元被制造为单相单元。这些单相单元以星形或三角形连接以构成完整的三相电容器组。虽然有很少的一些制造商制造三相电容器单元，但通常可用的电容器单元都是单相型的。在这种类型的电容器组中，熔断器单元从外部设置到每个电容器单元。在任何单元故障时，该单元的外部提供的保险丝将被熔断。当熔断系统断开故障电容器单元时，将继续其服务而不中断。在这种类型的电容器单元中并联连接。

由于每个电容器组的每相并联有几个电容器单元，因此在一个单元故障时，对整个组的性能没有太大影响。由于一个电容器单元在一个阶段丢失，该相的电容将低于其他两个相的电容。这将导致存储体的其它两相中的较高电压。如果电容器组中的一个电容器单元的容量足够低，则在组中没有任何单元时将不会有很大的电压不平衡。这就是为什么每个电容器单元的KVAR额定值被限制到指定的范围。电容器单元的额定值通常为50KVAR至40KVAR。

在外部熔断电容器组中，通过目视检查识别熔断器单元可以容易地识别故障单元。

这种类型的电容器组的主要缺点是，在任何熔断器单元故障时，将存在感测到的不平衡，即使该组的所有电容器单元都是完好的。

Product :DSQC 655 capacitor unit

ABB model name :-

The unit of a capacitor bank is usually called a capacitor unit. Capacitor units are manufactured as single-phase units. These single-phase units are connected in a star or triangle shape to form a complete three-phase capacitor bank. Although there are a few manufacturers of three-phase capacitor units, the capacitor units that are usually available are single-phase. In this type of capacitor bank, the fuse unit is set externally to each capacitor unit. In the event of any unit failure, the fuse provided externally to the unit will be blown. When the fuse system disconnects the faulty capacitor unit, it will continue its service without interruption. The capacitor unit of this type is connected in parallel.

Since there are several capacitor units in each parallel phase of each capacitor bank, there is not much impact on the performance of the whole group when one unit fails. Since a capacitor unit is lost in one phase, the capacitance of that phase will be lower than the capacitance of the other two phases. This results in higher voltages in the other two phases of the memory. If the capacity of one capacitor unit in the capacitor bank is low enough, there will not be a large voltage imbalance when there are no units in the group. This is why the KVAR rating of each capacitor unit is limited to a specified range. Capacitor units are typically rated from 50KVAR to 40KVAR.

In an external fusible capacitor bank, the faulty unit can be easily identified by identifying the fuse unit through visual inspection.

The main disadvantage of this type of capacitor bank is that there will be a perceived imbalance in the event of a failure of any fuse unit, even if all capacitor units in the group are intact.
