GGJ Low Voltage Intelligent Reactive Power Compensation Cabinet

Toonice's GGJ low voltage intelligent reactive power compensation cabinet is specially designed for actual grid conditions, adopting intelligent control technology. On the one hand, it effectively solves the problem of automatic switching of reactive power compensation for parallel capacitors under harmonic conditions. On the other hand, it can filter out harmonics according to actual user needs, purify the grid environment, reduce losses, eliminate harmonic hazards, and provide capacitive reactive power to the system to improve power factor. It can be applied to power distribution systems in industries such as power, metallurgy, petrochemical, industrial and mining enterprises, construction, and machinery.

Features and Applications

1. Complete functions and reliable performance: The GGJ low - voltage intelligent reactive power compensation cabinet has multiple functions, which can automatically perform compensation to increase the power factor above 0.9. It can display the power grid power factor in real - time, with a display range of lagging 0.00 - 0.99 and leading 0.00 - 0.99.

2. Comprehensive protection functions: The compensation cabinet has multiple comprehensive protection functions such as overvoltage, over - harmonic, over - compensation, system fault, phase - loss, overload, etc., to ensure the safe operation of the equipment.

3. Automatic memory function: The compensation cabinet can remember the set parameters. Even after a system power outage, the parameters will not be lost. After the power grid returns to normal, it will automatically enter the operating state without manual intervention.

4. Phase - split compensation and mixed compensation: According to the load balance of the power grid, the compensation cabinet can adopt phase - split compensation or mixed compensation methods to adapt to different load requirements.

5. Strong anti - interference ability: The GGJ low - voltage intelligent reactive power compensation cabinet can resist interference pulses with an amplitude of 2000V directly input from the power grid, having a high anti - interference ability.

6. Data monitoring and analysis functions: The equipment can real - time measure and record parameters such as three - phase voltage, current, frequency, active power, reactive power, and power factor on the low - voltage side of the transformer, and achieve remote data transmission and transcription through RS - 232 and RS - 485 interfaces. In addition, it can also conduct statistical analysis on operating load data, calculate indicators such as voltage qualification rate and power supply load rate, and draw relevant curves.

The main application areas of GGJ low-voltage reactive power compensation cabinet are: widely used in substations, factories, industrial and mining enterprises, large power plants, petroleum and chemical enterprises, large steel mills, high-rise building power centers, reactive power compensation and other occasions. Its rated voltage is 380V and rated frequency is 50HZ or 60HZ.
