MSCHA HV Reactive Automatic Compensation Device

MSCHA HV reactive automatic compensation device is a capacitor bank which automatically switches in steps and is connected in parallel with the 3~20kV busbar of the distribution transformer to provide the corresponding capacitive reactive power, according to the reactive load condition of the distribution transformer. The device adopts a unit building block design, each step has a circuit, and each circuit is independent into a cabinet, and the number of cabinets (number of circuits) can be expanded to increase the capacity. The series reactance can effectively suppress harmonics and inrush current, and the step-by-step switching can greatly improve the bus power factor and stabilize it at a certain level, thereby stabilizing the system voltage and improving the utilization rate of the transformer.

Summary: 

MSCHA HV reactive automatic compensation device is a capacitor bank which automatically switches in steps and is connected in parallel with the 3~20kV busbar of the distribution transformer to provide the corresponding capacitive reactive power, according to the reactive load condition of the distribution transformer. The device adopts a unit building block design, each step has a circuit, and each circuit is independent into a cabinet, and the number of cabinets (number of circuits) can be expanded to increase the capacity. The series reactance can effectively suppress harmonics and inrush current, and the step-by-step switching can greatly improve the bus power factor and stabilize it at a certain level, thereby stabilizing the system voltage and improving the utilization rate of the transformer.

Characteristics:

The modularized assembled cabinet is matched with the concave-convex door structure. The installation of components can be adjusted according to the modular position. It has strong three-dimensional sense and high mechanical strength.
The advanced power factor controller switches in stages and steps, automatically tracks the reactive power demand, switches quickly, and compensates accurately.
Equipped with ABB small PLC control system, it can manually and automatically switch without disturbance, with full automation and high reliability.
The spray-by-type fuse is used as the protection of a single capacitor, and its independent insulation interval ensures that there is no phase-to-phase and relative arcing after the action is dropped.
