Modular Compensation Unit (HLWB)

1Product Overview

Our company's low-voltage reactive power compensation filtering module highly integrates the main components of capacitors, filtering reactors, fuses, and switching switches into a self-contained system, transforming the production of traditional fixed cabinets into various mobile modules for production. This provides users with a wider range of usage space and offers more choices for switchgear manufacturers. At the same time, it also makes maintenance and repair work more flexible and convenient.

2. Device features

　 ◆ Optimal design: Non proportional design optimizes the number of circuits and switches,Improve reliability.

　 ◆ Single component:30Kvarand15KvarThe group can meet most capacity requirements.

　 ◆ Universal installation: The installation of this device is independent of the cabinet type and can be matched with various cabinets at home and abroad.

　 ◆ Combination assembly: Using modules is like building blocks, and various capacities and levels can be combined as needed.

　 ◆ Simple interface: Each module forms a relatively independent system and provides external power grid and control interfaces.

　 Compact structure: The reactive power capacity of a single cabinet is at least twice that of a traditional fixed complete cabinet.

　 ◆ Easy expansion: With the development of enterprise production, modules can be added at any time for expansion when the reactive capacity is insufficient.

　 Easy maintenance: The module can be directly removed or its components can be replaced,The remaining modules can continue to work.

　 ◆ Flexible incoming line: Both upper and lower incoming lines can be selected,The main circuit breaker can also be set.

3. Functional Features

　 ◆ Three phase compensation,Phase compensation,Three phase compensation and phase separation compensation mixed compensation.

　 Single reactive power compensation or dual selection of reactive power compensation and filtering.

　 ◆ Contactors, composite switches, or dynamic thyristor switching modes can be selected.

　 The vertical busbar system is equipped with low-voltage fuse protection, ensuring high safety.

　 The installation of the busbar does not require drilling, and it is installed with a matching busbar bracket.

　 ◆ Built in cooling fan, automatically controls fan start.

　 Multiple modules can be combined and installed in the same cabinet to facilitate the implementation of required functions and adapt to different load requirements.
