Description:

Smart LV shunt Capacitor to be in series with dry reactor, the module is mainly used for reactive power compensation in serious harmonic field.

In series with 6%～7% reactance ratio's reactor, the module is suitable for the electrical system where the main harmonic is 5 times; In series with 12%～13% reactance ratio's reactor, the module is suitable for the electrical system where the main harmonic is 3 times.

Simple understand, the module is one of single-tuned passive filter.

To be composed of:

The module consists of smart measure & control unit, high-power thyristor, dry reactor and LV filter capacitor.

Product Features: 

• To be used for dynamic reactive power compensation as well as single-tuned passive filtering.

• Zero-crossing switching

  No inrush current, No over-voltage and arcing during capacitor switching;

• Auto switching, dynamic compensation reactive power

  Smart capacitors could be automatically switched on and off according to the load reactive power, and dynamically compensate reactive power and improve the power quality;

• The hybrid compensation

  According to the magnitude of reactive power shortage in each phase, by the combination of three-phase and split-phase compensation, the three-phase are switched separately to achieve reactive power compensation optimization;

• Modular Architecture

  Smart capacitors are modular design, which can be used in single or a group;

  Simple connection and easy extension; The capacity expansion of reactive power compensation system can be realized only by increasing the number of modules.

• Perfect protections and alarms

  Smart capacitors have full protections against various hazards, such as over-voltage, over-current, under-voltage, harmonic over-limit protection; over-temperature protection based on its internal temperature components;

  Smart capacitors alarms includes capacity loss over-limit, switching fault, circuit fault alarm, communication fault,etc;

• Networking and fault tolerance

  Smart capacitors can be controlled by extra Var compensation controller, or simple networking by RS485;

  A lot of smart capacitor could be worked in parallel. One network is generated automatically, in which the one with the smallest address code is the host and the others are subsidiaries;

  One or some subsidiaries are quitted automatically when they fall. The other subsidiaries could work normally;

  Once the host is quitted, another new host will be generated from its subsidiaries.
