Power quality cabinets are widely used in power distribution rooms and industrial occasions that require large-capacity compensation. These cabinets are designed to provide multifunctional features such as harmonics, reactive power and unbalance cancellation. They are equipped with event logs, automatic alarms, fault records and a full-featured operator interface for parameter setting. In this blog, we will learn about the use, application and precautions of power quality cabinets.

application
The power quality cabinet contains APF/SVG modules and HYBAGK anti-harmonic capacitors (combined group). These modules are installed in the cabinet together with the incoming circuit breaker and fast acting fuses. The capacity of HYBAGK capacitor module is 5kvar-60kvar, and the capacity of APF/SVG module can be selected from 50A (35kvar), 100A (70kvar), and 100kvar. There are ventilation filter holes at the rear of the cabinet to adjust the temperature and humidity.

Precautions for use
To ensure the longevity and smooth operation of the power quality cabinet, necessary precautions must be taken. First, it is important to monitor the temperature and humidity of the cabinet to avoid overheating and excessive humidity. Regular cleaning of the ventilation filter holes is also recommended to prevent the buildup of dust and debris. Secondly, the cabinet must be installed in a cool and dry place, avoiding exposure to harsh environmental conditions. Finally, be sure to follow the instruction manual and seek professional help in case of any malfunction or abnormality.

advantage
Power quality cabinets offer several advantages over conventional power factor compensation (capacitor banks). Fast response, intelligent, simple structure. It is easy to maintain and expand, and operates quietly. In addition, the capacity of the HYBAGK capacitor module can be continuously adjusted to balance the reactive power required by the system and avoid over-compensation or under-compensation. The combination of APF/SVG modules eliminates harmonic currents and makes up for the shortcomings of traditional reactive power compensation.

in conclusion
In conclusion, power quality cabinets are multifunctional multipurpose cabinets designed to provide efficient power distribution and compensation of reactive power and harmonic currents. With proper installation and precautions, these cabinets can operate smoothly and ensure uninterrupted power supply.
