Product profile

The intelligent filter compensation module comprises of capacitor, reactor, thyristor electronic switch, DSP digital processing circuit, display circuit, etc. The product employs a split modular structure, which may either carry out individual independent running, or support a complete set of equipment in combination with multiple other units in a cabinet. It features in compact size, flexible combination, fast response and considerable filtering result.

This module provides functions of harmonic suppression, fast tracking, automatic zero-off and separate phase compensation. Its response time ≤ 20 ms, making it suitable for electric applications with frequent VAR variations or extreme requirement on voltage eligibility rate. The module may be provided with filter reactors of 6%, 7% or 12% in reactance ratio as required by working conditions, and can effectively suppress tertiary, quintic, septic and above current/voltage harmonics, hence it is particular suitable for power supply system with impact and frequent variations.

Model description

Product features

•Faster response time (down to below 20 ms), longer service life of thyristor, and no less than 1 million times of failure-free opening & closing.

•With reactor of appropriate reactance ratio in series, the amplification of background harmonics may be suppressed to avoid system resonance.

•Employing thyristor-controlled capacitor zero-off function, realizing switching free from surge, operation overvoltage and arc re-ignition.

•The modular cabinet has a nice-looking appearance and a compact drawer structure for easy maintenance;

•Satisfying cooling performance. Each module comes with an independent fan for temperature control that will activate air cooling automatically.

•Comprehensive protection measures. Each module is integrated with overvoltage, phase failure, overcurrent and overheating protection.

•Massive installed capacity of individual cabinet of up to 500 kvar.
