Main Components
| Component | Description |
|---|---|
| Power Capacitors | The core compensation components that provide capacitive reactive power. |
| Switching Devices | • Contactors: Economical, suitable for stable load conditions. • Thyristors (SCR): Enable dynamic compensation with zero-crossing switching, no inrush current, and fast response (millisecond level), ideal for rapidly changing loads. |
| Filter Reactors | Connected in series with capacitors to form "tuned" compensation. • Suppress Harmonics (e.g., 5th, 7th) Limit Inrush Current |
| Controller | Monitors system parameters such as power factor, voltage, and current in real time,and automatically controls to achieve precise compensation. |
| Protective Devices | Include fuses, thermal relays, circuit breakers,etc., ensuring the safe during faults such as overcurrent, overtemperature, or short circuits. |
Usage conditions:
● Ambient temperature:-5℃~+40℃
● Environmental relative humidity:not more than 90%(20℃)
● Altitude:≤ 2000m
● There is no explosion risk,no corrosive gas,no conductive dust
If the use conditions exceed above value,pls contact us
Features
● High Compatibility: The compensation cabinet can be flexibly combined with various cabinet types, such as MNS, GCK, GGD, etc.
● Diverse Compensation Modes: Supports Star (Y) compensation, Delta (Δ) compensation, and Y+Δ hybrid compensation for adaptable power factor correction.
● Multiple Communication Options: Equipped with RS-232/485 interfaces, wireless data transmission modules, or DSHRS modules for remote communication.
● Precise & Safe Control: Utilizes zero-voltage switching to eliminate inrush currents during activation and avoids high-voltage spikes during deactivation.
● Long Service Life: Maintenance-free operation with a lifespan exceeding 100,000 hours.
